    While more attention has been paid in recent years to urban point source pollution control through the establishment of wastewater treatment plants in many developing countries, no considerable planning nor any serious measures have been taken to control urban non-point source pollution (urban stormwater runoff). The present study is a screening analysis to investigate the pollution loads in urban runoff compared to point source loads as a first prerequisite for planning and management of receiving water quality. To compare pollutant loads from point and non-point urban sources, the pollutant load is expressed as the weight of pollutant per hectare area per year (kg/ha.year). Unit loads were estimated in stormwater runoff, raw sanitary wastewater and secondary treatment effluents in Isfahan, Iran. Results indicate that the annual pollution load in urban runoff is lower than the annual pollution load in sanitary wastewater in areas with low precipitation but it is higher in areas with high precipitation. Two options, namely, advanced treatment (in lieu of secondary treatment) of sanitary wastewater and urban runoff quality control systems (such as detention ponds) were investigated as controlling systems for pollution discharges into receiving waters. The results revealed that for Isfahan, as a low precipitation urban area, advanced treatment is a more suitable option, but for high precipitation urban areas, urban surface runoff quality control installations were more effective for suspended solids and oxygen-demanding matter controls, and that advanced treatment is the more effective option for nutrient control.

    Full Text Available Sewage may serve as a source of water and nutrients for plants. In this study, the effects of fertigation with treated sanitary wastewater from Janaúba Sewage Treatment Plant were evaluated on the postharvest and microbiological quality of ‘Prata-Anã’ banana. A randomized block experimental design was used. Four concentrations of wastewater were tested (70, 130, 170, and 200% of 150 kg ha-1 sodium. A wastewater-free control treatment was used for comparison. Two crop cycles were assessed for postharvest and microbiological quality. The parameters measured included total soluble solids, titratable acidity, total soluble solids/titratable acidity ratio, pH, total coliforms, and fecal coliforms on both the peel and the pulp. In the first crop cycle, both soluble solids and fruit pulp pH decreased as wastewater level increased up to a maximum of 141.5%. These correlations were not observed in the second cycle. Wastewater management did not affect the titratable acidity of the soluble solids. The agricultural application of treated sanitary wastewater provided banana fruits with a microbiological profile similar to that obtained with the control (pure water and with mineral fertilizers. A microbial balance is necessary to maintain the nutritional status of the banana crop.

    We investigated 33 pharmaceuticals and personal care products (PPCPs) with emphasis on anthelmintics and their metabolites in human sanitary waste treatment plants (HTPs), sewage treatment plants (STPs), hospital wastewater treatment plants (HWTPs), livestock wastewater treatment plants (LWTPs), river water and seawater. PPCPs showed the characteristic specific occurrence patterns according to wastewater sources. The LWTPs and HTPs showed higher levels (maximum 3000 times in influents) of anthelmintics than other wastewater treatment plants, indicating that livestock wastewater and human sanitary waste are one of principal sources of anthelmintics. Among anthelmintics, fenbendazole and its metabolites are relatively high in the LWTPs, while human anthelmintics such as albendazole and flubendazole are most dominant in the HTPs, STPs and HWTPs. The occurrence pattern of fenbendazole's metabolites in water was different from pharmacokinetics studies, showing the possibility of transformation mechanism other than the metabolism in animal bodies by some processes unknown to us. The river water and seawater are generally affected by the point sources, but the distribution patterns in some receiving water are slightly different from the effluent, indicating the influence of non-point sources.

    To complete a parasitological survey, entomological prospections were carried out in the southern sanitary District of Dakar, the most urbanized of the city and which includes the city centre and the oldest administrative districts. The prospections took place between June 1994 and May 1995 in sites 1.5 km apart, and distributed in such a manner that they covered the entire area. On a monthly basis, female Culicidae were collected in each site at night on human volunteers, followed the next day by the collection of early morning residual fauna in 10 bedrooms located in district concessions. For a total of 308 collections at night on human volunteers and from 1,510 rooms for the residual fauna, 22,901 female Culicidae were caught of which 167 anopheles, corresponding to 0.7%, the remaining 98.5% being Culex quinquefasciatus. This was the species that thus explained the mosquito-nuisance of which the inhabitants of the southern District complained during the period of survey. The female anopheles collected belonged to 2 species, An. arabiensis for 97.6% of those caught and An. pharoensis for 2.4%. An. arabiensis were very slightly represented in the southern District with a density of aggressive females of 0.26 bite/man/night (B/M/N) and a density per room of 0.05 female. The aggressive populations appeared to be relatively important only at the end of the rainy season (September-October) with an average of 0.65 B/M/N in sites located at the periphery of the district with a maximum of 1.33 B/M/N. The highest density of endophilic females registered at the end of the rainy season was 0.1 and its highest value in a given site was 0.36 female/room. The parturity rate of aggressive females was 43.5% and those collected in houses of 84% with an anthropophilic index of 0.98. None of the dissected An. arabiensis females (77.3% of those collected) was a carrier of Plasmodium sporozoites and the circum-sporozoite antigen was not found. A very weak density of An. arabiensis

    Starr, Robert Charles; Green, Timothy Scott; Hull, Laurence Charles

    2001-02-01

    A review has been performed of existing information that describes geology, hydrogeology, and geochemistry at the South District Wastewater Treatment Plant, which is operated by the Miami-Dade Water and Sewer Department, in Dade County, Florida. Treated sanitary wastewater is injected into a saline aquifer beneath the plant. Detection of contaminants commonly associated with treated sanitary wastewater in the freshwater aquifer that overlies the saline aquifer has indicated a need for a reevaluation of the ability of the confining layer above the saline aquifer to prevent fluid migration into the overlying freshwater aquifer. Review of the available data shows that the geologic data set is not sufficient to demonstrate that a competent confining layer is present between the saline and freshwater aquifers. The hydrogeologic data also do not indicate that a competent confining layer is present. The geochemical data show that the freshwater aquifer is contaminated with treated wastewater, and the spatial patterns of contamination are consistent with upward migration through localized conduits through the Middle Confining Unit, such as leaking wells or natural features. Recommendations for collection and interpretation of additional site characterization data are provided.

  12. Sanitary Quality of Raw Milk within the Commodity Subsector in Mbarara District and Kampala City in Uganda

    2005-04-01

    Full Text Available The sanitary quality of raw milk is an important issue in Uganda for social, economical and health reasons. The present study carried out on the informal raw milk subsector of Uganda highlighted two main issues: (i poor hygiene conditions from the production location all the way to the consumer; (ii lack of an efficient preservation system to limit bacteria development during transportation to Kampala. The bacteria population reached very high levels close to 2 x 106 colony forming units per milliliter on the farm milk of Mbarara District in the southwestern region of the country, and these levels increased 150-fold during transportation to Kampala. The sector also includes rudimentary pasteurization units, where the overheated milk comes out bacteria-free. However, conservation over several days of the overheated milk makes this process potentially more dangerous than beneficial. Thus, the need for all the players of the sector to implement a strategy to improve milk quality can be two ways: (i by changing common practices to ensure better hygiene conditions; (ii by improving milk preserving through new methods such as cooling, small-scale pasteurization, or the use of the lactoperoxidase system. This study can help develop a technical and scientific basis to generate quality improvement actions in Uganda. But, whatever the strategy adopted by decision makers, it can only be implemented if all the stakeholders of the sector are involved.

    The article describes the results of studying the problems of industrial wastewater treatment using higher aquatic vegetation (hydrophytes) in the former mining enterprise of the Far Eastern Federal District (FEFD). They are aimed at reducing the negative environment impact of toxic tin ore wastes. The material of research were drainage, mine and slime waters as well as Lemna minor and Common reed grass (Phragmites communis). In the work conventional modern physico-chemical, chemical, biological and mathematical-statistical methods were used, as well as in the process of research the methods of atomic absorption spectrophotometry for AAS and mass spectrometry with inductively coupled plasma on ISP-MS ELASN DRS II PerkinElmer was applied. The data obtained in the course of the experiment (2015-2016), indicate that a degree of wastewater treatment, using Lemna minor, is high. Virtually, all compounds of toxic chemical elements contained in industrial wastewater (zinc, cobalt, nickel, cadmium, iron, manganese, lead, etc.) were fully absorbed by a hydrophyte. Pollutant extraction was almost 95%. The obtained results of the study in laboratory conditions proved the possibility of effective use of the Lemna minor for the purification of drainage and mine waters. A key contribution of this paper is the relationship between possible toxic metals contained in industrial wastewater and a higher degree of absorption by their higher aquatic vegetation. These hydrophytes absorb these possible toxic metals in an aqueous medium and are contaminated with these heavy metals.

    Nonhazardous, secondarily treated, domestic wastewater (effluent) has been injected about 1 kilometer below land surface into the Boulder Zone of the Floridan aquifer system at the North District Wastewater Treatment Plant in southeastern Florida. The Boulder Zone contains saline, nonpotable water. Effluent transport out of the injection zone is a risk of underground effluent injection. At the North District Wastewater Treatment Plant, injected effluent was detected outside the Boulder Zone. The U.S. Geological Survey, in cooperation with Miami-Dade Water and Sewer Department, investigated effluent transport from the Boulder Zone to overlying permeable zones in the Floridan aquifer system.One conceptual model is presented to explain the presence of effluent outside of the injection zone in which effluent injected into the Boulder Zone was transported to the Avon Park permeable zone, forced by buoyancy and injection pressure. In this conceptual model, effluent injected primarily into the Boulder Zone reaches a naturally occurring feature (a karst-collapse structure) near an injection well, through which the effluent is transported vertically upward to the uppermost major permeable zone of the Lower Floridan aquifer. The effluent is then transported laterally through the uppermost major permeable zone of the Lower Floridan aquifer to another naturally occurring feature northwest of the North District Wastewater Treatment Plant, through which it is then transported vertically upward into the Avon Park permeable zone. In addition, a leak within a monitoring well, between monitoring zones, allowed interflow between the Avon Park permeable zone and the Upper Floridan aquifer. A groundwater flow and effluent transport simulation of the hydrogeologic system at the North District Wastewater Treatment Plant, based on the hypothesized and non-unique conceptualization of the subsurface hydrogeology and flow system, generally replicated measured effluent constituent

    Untreated wastewater from the Mexico City basin has been used for decades to irrigate cropland in the Mezquital Valley, State of Hidalgo, Mexico. Excess irrigation water recharges the near-surface aquifer that is used as a domestic water supply source. We assessed the groundwater quality of three key groundwater sources of domestic water by analyzing for 24 trace metals, 67 target base/neutral/acid (BNA) organic compounds, nontarget BNA organics, 23 chlorinated pesticides, 20 polychlorinated biphenyls, and nitrate, as well as microbiological contaminants--coliforms, Vibrio cholerae, and Salmonella. Study participants answered a questionnaire that estimated ingestion and dermal exposure to groundwater; 10% of the sample reported frequent diarrhea and 9% reported persistent skin irritations. Detection of V. cholerae non-01 in surface waters at all sites suggested a potential risk (surrogate indicator present) of diarrheal disease for canal and river bathers by accidental ingestion, as well as potential Vibrio contamination of near-surface groundwater and potential cholera risk, magnified by lapses in disinfection. High total coliform levels in surface water and lower levels in groundwater at all sites indicated fecal contamination and a potential risk of gastrointestinal disease in populations exposed to inadequately disinfected groundwater. Using chemical criteria, no significant risk from ingestion or dermal contact was identified at the method detection limits at any site, except from nitrate exposure: infants and young children are at risk from methemoglobinemia at all sites. Results suggest that pathogen risk interventions are a priority, whereas nitrate risk needs further characterization to determine if formal treatment is needed. The risks exist inside and outside the irrigation district. The method was highly cost-effective.

    Full Text Available Regulatory practices in the field of health surveillance are indispensable. The aim of this study is to show ‒ taking the Brazilian National Surveillance Agency, governing body of sanitary surveillance in Brazil as a reference ‒ that bioethics provides public bodies a series of theoretical tools from the field of applied ethics for the proper exercise and control of these practices. To that end, the work uses two references of bioethics for the development of a comparative and supportive analysis to regulatory activities in the field of health surveillance: the Universal Declaration on Bioethics and Human Rights of Unesco and the theory of intervention bioethics. We conclude that organizations and staff working with regulatory activities can take advantage of the principles and frameworks proposed by bioethics, especially those related to the Declaration and the theory of intervention bioethics, the latter being set by the observation and use of the principles of prudence, precaution, protection and prevention.

    Full Text Available We assessed the occurrence of Vibrio pathogens in the final effluents of five wastewater treatment plants (WWTPs located in Amathole and Chris Hani District Municipalities in South Africa over a 12 months period between September 2012 and August 2013 using standard membrane filtration technique followed by cultivation on thiosulphate citrate-bile salts-sucrose (TCBS agar. The identities of the presumptive Vibrio isolates were confirmed using polymerase chain reaction (PCR including delineation into V. parahaemolyticus, V. vulnificus and V. fluvialis pathotypes. The counts of Vibrio spp. varied with months in all the study sites and ranged in the order of 101 and 104 CFU/100mL. Vibrio distribution also showed seasonality with high counts being obtained in autumn and spring (p < 0.05. Prevalence of Vibrio spp. among the five WWTPs also differed significantly (p < 0.05. Of the 300 isolates that were confirmed as belonging to the Vibrio genus, 29% (86 were V. fluvialis, 28% (84 were V. vulnificus and 12% (35 were V. parahaemolyticus. The isolation of Vibrio pathogens from the final effluent suggests that this pathogen is in circulation in some pockets of the population and that the WWTPs under study do not efficiently remove bacterial pathogens from the wastewater and consequently are threats to public health.

    Full Text Available Polycyclic aromatic hydrocarbons are very toxic and persistent environmental contaminants. This study was undertaken to assess the concentrations and possible sources of 16 PAHs (Polycyclic aromatic hydrocarbons classified by the United State Environmental Protection Agency as priority pollutants in water and sediments of the Mvudi and Nzhelele Rivers. Effluents from Thohoyandou wastewater treatment plant and Siloam waste stabilization ponds were also investigated. Diagnostic ratios were used to evaluate the possible sources of PAHs. PAHs in the water samples were extracted using 1:1 dichloromethane and n-hexane mixtures, while those in the sediment samples were extracted with 1:1 acetone and dichloromethane using an ultrasonication method. The extracts were purified using an SPE technique and reconstituted in n-hexane before analyses with a gas chromatograph time of flight—mass spectrometer. The results obtained indicate the prevalence of high molecular weight PAHs in all the samples. PAHs concentrations in water and sediment samples from all the sampling sites were in the range of 13.174–26.382 mg/L and 27.10–55.93 mg/kg, respectively. Combustion of biomass was identified as the major possible source of PAHs. Effluents from wastewater treatment facilities were also considered as major anthropogenic contributions to the levels of PAHs found in both river water and sediments. Mvudi and Nzhelele Rivers show moderate to high contamination level of PAHs.

    Full Text Available A combinação de processos físico-químicos e biológicos no tratamento de esgotos sanitários tem se apresentado como uma alternativa na remoção de fósforo. No entanto, uma das limitações é a sua maior produção de lodo. Desse modo, este trabalho teve por objetivo avaliar a produção de lodo resultante da aplicação de sais de ferro para diferentes tipos de efluentes, bem como estudar o impacto de sua aplicação nas características físico-químicas dos efluentes estudados. Concluiu-se que os valores médios de produção de lodo resultante da formação do hidróxido férrico situaram-se em torno de 1,80; 1,95 e 1,34 mg lodo/mg Fe+3 para esgoto bruto, efluente aeróbio e anaeróbio tratado, respectivamente, indicando que as características da fase líquida não influenciaram os mecanismos de precipitação dos íons férricos.The combination of physical-chemical and biological processes in sanitary wastewater treatment has been employed as an alternative for phosphorus removal; however, one of its limitations is its large sludge production. This work aimed at evaluating the sludge production which resulted from iron salt application to different types of effluents, as well as studying the impacts of iron salt application on the physical-chemical characteristics of the studied effluents. It was concluded that the average sludge production values which resulted from ferric hydroxide formation were around 1.80, 1.95 and 1.34 mg sludge per mg of Fe+3 ion, with regard to raw wastewater, aerobic treated effluent and anaerobic treated effluent, respectively, thus indicating that the liquid phase characteristics did not influence the ferric ion precipitation mechanisms.

    Full Text Available The objective of this study was to investigate the efficiency of germicidal lamps in the tertiary treatment of sewage to control pathogens. The performance of the photochemical reactor used in the tests was monitored by microbiological analyses to quantify E. coli (bacteria indicator, C. perfringens (protozoa indicator, coliphages (virus indicator. The experiments were performed with effluent from an UASB reactor installed at the WTP- USP São Carlos campus subjected to an aerated submerged biological filter and a photochemical reactor with radiation UV at 254 nm. The results showed that the indicators coliphages and E. coli showed the least resistance to UV radiation reaching removal from 1.70 to 3.90 log and 1.60 to 5.20 log, respectively. On the other hand, the indicator C. perfringens was more resistant to the effect of germicidal lamps reaching values between 0.0 (no inactivation and 1.30 log. For SST concentrations greater than 100.0 mg.L-1, the effect of the germicidal lamps became less pronounced. However, in practice it was possible to notice significant results in tests with TSS concentrations of 135.0 mg.L-1. The experimental approach proved the usefulness of the combined method for inactivating pathogens commonly found in domestic sewage. Besides meeting the standards established by the Brazilian regulation, the final effluent is in agreement with the guidelines defined by WHO. This allows the reuse of the final effluent for unrestricted irrigation, although complementary examination must be performed.

MÉTODOS: estudo avaliativo transversal. Os dados foram coletados a partir de entrevistas realizadas junto aos profissionais das onze equipes de PACS e PSF. A análise dos dados contemplou duas dimensões: acesso da população e lógica de territorialização. RESULTADOS: o distrito apresentava relevo bastante acidentado e todas as equipes informaram a existência de barreiras geográficas na área, em especial escadarias, morros e ladeiras. Não foi observada diferença significativa na acessibilidade às equipes de PACS e PSF. O processo de territorialização esteve dissociado da concepção de território-processo. Algumas áreas de abrangência das equipes situavam-se em locais afastados das UBS, constituindo-se em importante barreira ao acesso da população. CONCLUSÕES: o processo de implantação da estratégia PACS/PSF no distrito e o modelo de territorialização adotado não atenderam aos princípios que devem nortear a organização da atenção primária à saúde, resultando em restrições na acessibilidade geográfica da população coberta. Recomenda-se que seja realizada uma revisão do desenho atual da territorialização, visando uma melhor adequação às diretrizes do PSF e à promoção de uma maior acessibilidade à atenção primária.OBJECTIVES: to assess the geographical accessibility of primary health care for the population served by the Community Health Agents Program (PACS and the Family Health Program (PSF in one sanitary district in the city of Salvador, Brazil.

    Full Text Available The global growth of cruise tourism has brought increasing concern for the pollution of the marine environment. Marine pollution from sanitary wastewater is a problem especially pronounced on large cruise ships where the number of people on board may exceed 8,000. To evaluate future marine pollution in any selected period of time it is necessary to know the movement of ships in the Adriatic Sea. This paper presents the problem of marine pollution by sanitary wastewater from cruise ships, wastewater treatment technology and a model of cruise ship traffic in the Adriatic Sea considering MARPOL Annex IV areas of limited wastewater discharge. Using the model, it is possible to know in advance the routes of the cruisers and retention time in certain geographic areas. The data obtained by this model can be used as input parameters for evaluation model of wastewater pollution or for evaluation of other types of pollution from cruise ships.

    Full Text Available The goal of the present work was to investigate the occurence of canine Visceral Leishmaniasis (VL in Itapuã, Cajazeiras and Pau da Lima sanitary districts (SD, all belonging to the city of Salvador. In order to achieve it, a canine epidemiological and entomological surveys were applied as an epidemiological questionnaire to the owners of the animals sampled and to the veterinary physicians of the city. The study detected six VL seropositive dogs among the eight hundred and eleven ones randomly sampled. It was not possible to determine the autoctonous condition for L. chagasi infection. One animal was positive by culture of splenic material and in the entomologic survey of the vector, Lutzomyia longipalpis, none was captured. Veterinary clinicians from 41.7% of the clinics evaluated reported the diagnostic of, at least, one VL case in Salvador domiciliated dogs. The SD of Itapuã, Cajazeiras and Pau da Lima presented VL transmission risk once there is Leishmania parasite occurrence in the municipality, verified in this study by splenic culturing of an animal aspirative puncture, previous record of vector (L. longipalpis presence in the Itapuã district by the Bahia State Health Agency (SESAB and canine VL diagnostics by veterinary doctors from clinics all around the city of Salvador. This work is the first epidemiological analysis of this zoonosis in these SD and they point out the need to perform sampled entomological and serological surveys in all areas of the city. The development of a VL surveillance system may contribute for monitoring the disease in Salvador.Objetivou-se com este estudo investigar a ocorrência da Leishmaniose Visceral (LV canina nos Distritos Sanitários (DS de Itapuã, Cajazeiras e Pau da Lima, pertencentes ao município de Salvador, por meio da realização de inquérito sorológico canino; inquérito entomológico, aplicação de questionário epidemiológico aos proprietários dos animais amostrados e a m

    Vibrios and other enteric pathogens can be found in wastewater effluents of a healthy population. We assessed the prevalence of three non-cholerae vibrios in wastewater effluents of 14 wastewater treatment plants (WWTP) in Chris Hani and Amathole district municipalities in the Eastern Cape Province of South Africa for a period of 12 months. With the exception of WWTP10 where presumptive vibrios were not detected in summer and spring, presumptive vibrios were detected in all seasons in other WWTP effluents. When a sample of 1,000 presumptive Vibrio isolates taken from across all sampling sites were subjected to molecular confirmation for Vibrio, 668 were confirmed to belong to the genus Vibrio, giving a prevalence rate of 66.8 %. Further, molecular characterisation of 300 confirmed Vibrio isolates revealed that 11.6 % (35) were Vibrio parahaemolyticus, 28.6 % (86) were Vibrio fluvialis and 28 % (84) were Vibrio vulnificus while 31.8 % (95) belonged to other Vibrio spp. not assayed for in this study. Antibiogram profiling of the three Vibrio species showed that V. parahaemolyticus was ≥50 % susceptible to 8 of the test antibiotics and ≥50 % resistant to only 5 of the 13 test antibiotics, while V. vulnificus showed a susceptibility profile of ≥50 % to 7 of the test antibiotics and a resistance profile of ≥50 % to 6 of the 13 test antibiotics. V. fluvialis showed ≥50 % resistance to 8 of the 13 antibiotics used while showing ≥50 % susceptibility to only 4 antibiotics used. All three Vibrio species were susceptible to gentamycin, cefuroxime, meropenem and imipenem. Multiple antibiotic resistance patterns were also evident especially against such antibiotics as tetracyclin, polymixin B, penicillin G, sulfamethazole and erythromycin against which all Vibrio species were resistant. These results indicate a significant threat to public health, more so in the Eastern Cape Province of South Africa which is characterised by widespread poverty, with more than a

    As a first approximation to wastewater classification in susceptibility terms to treatment by anaerobic biological system, anaerobic biodegradability trials are accomplished to leached of sanitary landfill, to wastewater of coffee grain wet treatment plant and to wastewater of fumaric acid recuperation plant. In the last Plant, anaerobic toxicity trials and lethal toxicity on the Daphnia pulex micro-crustacean are made too. Anaerobic biological trials are made continuing the Wageningen University (Holland) Methodology (1.987). Lethal toxicity biological trials are made following the Standard Methods for the Examination of Water and Wastewater(18th edition, 1992). In development of this investigation project is found that fumaric acid recuperation plant leached it has a low anaerobic biodegradability, a high anaerobic toxicity and a high lethal toxicity over Daphnia pulex, for such reasons this leached is cataloged as complex and toxic wastewater. The other hand, wastewater of coffee grain wet treatment plant and wastewater of sanitary landfill they are both highly biodegradability and not-toxic, for such reasons these wastewaters are cataloged as susceptible to treatment by anaerobic biological system

    The US Department of Energy (DOE) Hanford Site is located in southeastern Washington State. The Hanford Site is approximately 1,450 sq. km (560 sq. mi) of semiarid land set aside for activities of the DOE. The reactor fuel processing and waste management facilities are located in the 200 Areas. Over the last 50 years at Hanford dicard of hazardous and sanitary waste water has resulted in billions of liters of waste water discharged to the ground. As part of the TPA, discharges of hazardous waste water to the ground and waters of Washington State are to be eliminated in 1995. Currently sanitary waste water from the 200 Area Plateau is handled with on-site septic tank and subsurface disposal systems, many of which were constructed in the 1940s and most do not meet current standards. Features unique to the proposed new sanitary waste water handling systems include: (1) cost effective operation of the treatment system as evaporative lagoons with state-of-the-art liner systems, and (2) routing collection lines to avoid historic contamination zones. The paper focuses on the challenges met in planning and designing the collection system

    Wastewater collection systems are an important component of proper management of wastewater to prevent environmental and human health implications from mismanagement of anthropogenic waste. Due to aging and inadequate asset management practices, the wastewater collection assets of many cities around the globe are in a state of rapid decline and in need of urgent attention. Risk management is a tool which can help prioritize resources to better manage and rehabilitate wastewater collection systems. In this study, a risk matrix and a weighted sum multi-criteria decision-matrix are used to assess the consequence and risk of sewer pipe failure for a mid-sized city, using ArcGIS. The methodology shows that six percent of the uninspected sewer pipe assets of the case study have a high consequence of failure while four percent of the assets have a high risk of failure and hence provide priorities for inspection. A map incorporating risk of sewer pipe failure and consequence is developed to facilitate future planning, rehabilitation and maintenance programs. The consequence of failure assessment also includes a novel failure impact factor which captures the effect of structurally defective stormwater pipes on the failure assessment. The methodology recommended in this study can serve as a basis for future planning and decision making and has the potential to be universally applied by municipal sewer pipe asset managers globally to effectively manage the sanitary sewer pipe infrastructure within their jurisdiction.

    This work is carried out in Veracruz State covering over 11 jurisdictions of the State (Panuco, Tuxpan, Poza Rica, Martinez de la Torre, Xalapa, Cordoba, Orizaba, Veracruz, Cosamaloapan, San Andres Tuxtla and Coatzacoalcos). The sampling was realized in a period from 2009 to 2013 analyzing home drinking water, supply sources and wells, the sampling was done by the sanitary checkers of different jurisdictions with approved methods and the methodology was validated at the State Laboratory of Public Health. 1637 samples were analyzed by counting equipment Tennelec Canberra series 5 and a gas supply system P-10 with calibration curves for alpha and gross beta. The results of measurements ranging from 0.07 to 0.25 Bq/L in the activity concentration gross alpha annual average, an gross beta were from 0.12 to 0.17 Bq/L in the activity concentration gross beta annual average, and with a concentration range of alpha activity up to 0.62 and a minimum 0.02, and the concentration of beta activity of a maximum value 1.54 and a minimum 0.02, taking also as resulted in five years of analysis only 1.16% of the analyzed samples (19 samples) showed a value of alpha activity concentration above the minimum detectable concentration and 62.43% (1022 samples) of the analyzed samples showed a value of beta activity concentration above the minimum detectable concentration, is also clear that the results of the sanitary jurisdictions of Panuco and Tuxpan not have corresponding activity values for the years 2009, 2011-2013 except 2010. We can conclude that the regular measurements of alpha and gross beta activity in water are invaluable for timely detection of radioactive contamination. (Author)

    In the field of rehabilitation of separate sanitary sewer systems, a large number of technical, environmental, and economic aspects are often relevant in the decision-making process, which may be modelled as a multi-objective optimization problem. Examples are those related with the operation and assessment of networks, optimization of structural, hydraulic, sanitary, and environmental performance, rehabilitation programmes, and execution works. In particular, the cost of investment, operation and maintenance needed to reduce or eliminate Infiltration from the underground water table and Inflows of storm water surface runoff (I/I) using rehabilitation techniques or related methods can be significantly lower than the cost of transporting and treating these flows throughout the lifespan of the systems or period studied. This paper presents a comprehensive I/I cost-benefit approach for rehabilitation that explicitly considers all elements of the systems and shows how the approximation is incorporated as an objective function in a general evolutionary multi-objective optimization model. It takes into account network performance and wastewater treatment costs, average values of several input variables, and rates that can reflect the adoption of different predictable or limiting scenarios. The approach can be used as a practical and fast tool to support decision-making in sewer network rehabilitation in any phase of a project. The fundamental aspects, modelling, implementation details and preliminary results of a two-objective optimization rehabilitation model using a genetic algorithm, with a second objective function related to the structural condition of the network and the service failure risk, are presented. The basic approach is applied to three real world cases studies of sanitary sewerage systems in Coimbra and the results show the simplicity, suitability, effectiveness, and usefulness of the approximation implemented and of the objective function proposed

    The Almendares river, one of the most important water bodies of the Havana City, is very polluted. The analysis of parameters as dissolved oxygen, biochemical oxygen demand and ammonium is very helpful for the studies aimed to the recovery of the river. There is a growing recognition around the word that the water quality models are very useful tools to plan sanitary strategies for the management of wastewater contamination to predict the effectiveness of control options to improve water quality to desired levels. In the present work, the advective, steady- state, one-dimensional Streeter and Phelps model, calibrated and validated was used to elaborate environment strategies to improve the water quality of the Almendares river. The use of the 99mTc and the Rodamina WT as tracers allowed determining the hydrodynamic parameters necessary for modelling purposes. (Author)

    1995-01-01

    TNX has a large supply of 55 gallon drums containing pure glycerin and glycerin with additives. The glycerin drums were procured to simulate the glass stream in a pilot-scale melter process at TNX. Since the glycerin was not used for this process, TNX is looking at disposing the material in a sanitary waste treatment facility onsite. The effect of adding the contents of the drums to sewage bacteria was tested. A drum of pure glycerin and a drum of glycerin mixed with lithium chloride were tested. The test consisted of mixing sanitary sludge material with the glycerin material. The purpose of the test was to determine if the glycerin impacted the aerobic bacterial population. The bacterial densities were determined by taking samples from the sludge/glycerin mixtures and using aerobic plate count methods. The total organic carbon (TOC) levels were measured before and after testing. The results indicate that the cell density of the aerobic bacteria increased with the addition of glycerin and the glycerin mixture and the TOC removal rate was different for all tests. Disposal of glycerin in the wastewater treatment facilities should pose no problems. Additional testing and analysis of the mixed samples should be done before its disposal in a waste water treatment facility

  14. Municipal Treated Wastewater Irrigation: Microbiological Risk Evaluation

    Full Text Available Municipal wastewater for irrigation, though treated, can contain substances and pathogens toxic for humans and animals. Pathogens, although not harmful from an agronomical aspect, undoubtedly represent a major concern with regards to sanitary and hygienic profile. In fact, vegetable crops irrigated with treated wastewater exalt the risk of infection since these products can also be eaten raw, as well as transformed or cooked. Practically, the evaluation of the microbiological risk is important to verify if the microbial limits imposed by law for treated municipal wastewater for irrigation, are valid, thus justifying the treatments costs, or if they are too low and, therefore, they don’ t justify them. Different probabilistic models have been studied to assess the microbiological risk; among these, the Beta-Poisson model resulted the most reliable. Thus, the Dipartimento di Scienze delle Produzioni Vegetali of the University of Bari, which has been carrying out researches on irrigation with municipal filtered wastewater for several years, considered interesting to verify if the microbial limits imposed by the italian law n.185/03 are too severe, estimating the biological risk by the probabilistic Beta-Poisson model. Results of field trials on vegetable crops irrigated by municipal filtered wastewater, processed by the Beta-Poisson model, show that the probability to get infection and/or illness is extremely low, and that the actual italian microbial limits are excessively restrictive.

    Wastewater is a mixture of domestic, municipal and industrial waste dissolved in water. The biggest fraction of wastewater is sanitary sewer water. Before its release in rivers or sea, water must be cleaned and all harmful bacteria must be killed. Biosolids are nutrient-rich organic waste obtained following wastewater treatment and used beneficially as fertilizer. Routinely, biosolids are deposited in agricultural areas or incinerated. For this reason the level of microbial pathogens in the b...

    The US Nuclear Regulatory Commission (NRC), in accordance with 10 CFR 20, and agreement states, in accordance with state regulations, regulates the discharge of radioactive materials into sanitary sewer systems. A one-year study was conducted by Pacific Northwest Laboratory (PNL) for the NRC to assess whether radioactive materials that are dischared to sanitary sewer systems undergo significant reconcentration within the wastewater treatment plants (WWTP) and to determine the physical and/or chemical processes that may result in radionuclide reconcentration within the WWTPs. The study objectives were addressed by collecting information and data on wastewater treatment, relevant geochemical processes, and individual radionuclide behavior in WWTPs from the open literature, NRC reports, EPA surveys, and interviews with NRC licensees and staff of WWTPs that may be impacted by these discharges. Radionuclide mass balance and removal efficiencies were calculated for WWTPs at Oak Ridge, TN; and Erwin, TN, but were not shown to be reliable since the licensee release data generally underestimated the mass of radionuclide that was ultimately found in the sludge. This disparity may be due, in part, to the fact that data available for use in this study were collected to address regulatory concerns and not to perform mass balance calculations. A limited modeling study showed some promise for predicting radionuclide behavior in WWTPS, however, the general applicability of using these empirical models remains uncertain. With the data and models currently available, it is not possible to quantitatively determine the physical and chemical processes that cause reconcentration or to calculate, a priori, reconcentration factors for specific WWTP unit processes or WWTPs in general

    As part of IPEN's Environmental Monitoring Program, wastewater sample collection and analysis was implemented on a daily basis. CQMA- Centro de Quimica e Meio Ambiente was responsible for the determination of total, fixed and volatile solids, pH, metals (as Al, Sb, Ba, Cd, Pb, Co, Cu, Cr, Hg, Mo, Ni, Ag, Na, Zn, Ca, Mg, Be, Sn, Li, K, Sr, Ti and V), semimetals (As, B, Se and Si) and anions (such as chloride, nitrate, sulfate and fluoride). The results were compared to the legal values established by the Sao Paulo State regulation 8,468/76, which defines the maximum permitted values for most of the studied substances in wastewater, aiming its releasing in public wastewater treatment system. The evaluation of this parameters concentration on Ipen's effluent implies that 50% of the wastewater corresponds to organic matter due to the sanitary load and inorganic macro elements, mainly as sodium, potassium, calcium. The only parameter not found in accordance with Brazilian legislation was pH in four out of the one hundred and seven samples collected throughout 2009 (2.8% of the samples analyzed). This preliminary study showed the effluents generated at Ipen's facility is characterized by the presence of organic matter and macro elements, commonly found in sanitary wastewater and it is in compliance with Sao Paulo regulations.

    Full Text Available The paper outlines the first stages of sanitary activities development in Perm region. We highlight the fact that it was Perm where I.I. Molessson, the first official sanitary inspector in Russia, worked. Here one of the first sanitary inspection of a whole region was performed and "Perm sanitary bulletin" was first published. It was in Perm, where the first sanitary office was established in 1890, and in 1898 the first bacteriological laboratory was organized. Bodies and institutions of Rospotrebnadzor in Perm region are known to be founded on September 15, 1922, when a Decree by Russian People's Commissars Council "On the Republic's sanitary bodies" was issued. A sanitary-hygienic faculty of Perm Medical Institute was set up in 1931 and it gave grounds for preparing qualified sanitary inspectors for state sanitary authorities. We described basic tasks which were tackled by sanitary inspectors during the Great Patriotic War and just after it. Rospotrebnadzor activities are proved to make for substantial improvements of sanitary-epidemiologic situation in the region. Currently more than 95 % of population are provided with drinking water which fully corresponds to the sanitary legislation requirements. We note constant improvements in catering objects quality and we also see that a quantity of food samples taken at such objects which don't correspond to hygienic standards remains stably low. A share of working places deviating from hygienic standards as per noise, vibration, and illumination, has reduced. Medical examinations are now available to 97.9 % of workers functioning under hazardous (dangerous working conditions. The lowest occupa-tional morbidity level over the last few years was registered in Perm region in 2016. The Service was among the first in the country to transfer to result-oriented budgeting and risk-oriented surveillance model. Organizational structure is constantly being developed; new legal, economic and organizational

The local conditions including regulations, institutions, financial mechanisms, availability of local technology and stakeholder participation have a great influence on the decisions for wastewater reuse. The increasing awareness of food safety and the influence of the countries which import food are influencing policy makers and agriculturists to improve the standards of wastewater reuse in agriculture. The environmental awareness of consumers has been putting pressure on the producers (industries to opt for environmentally sound technologies including those which conserve water and reduce the level of pollution. It may be observed that we have to move forwards to implement strategies and plans for wastewater reuse. However, their success and sustainability will depend on political will, public awareness and active support from national and international agencies to create favorable    environment for the promotion of environmentally sustainable technologies. Wastewater treatment has a long history, especially in agriculture, but also in industry and households. Poor quality of wastewater can pose a significant risk to the health of farmers and users of agricultural products. The World Health Organization (WHO is working on a project for the reuse of wastewater in agriculture. To reduce effects of human activities to the minimum, it is necessary to provide such technical and technological solutions that would on the one hand ensure complying with  the existing regulations and legislation, and on the other hand provide economically viable systems as seen through investments and operating costs.

The procedure of stopping the operation of a household treatment plant that doesn’t meet the statutory wastewater treatment efficiency was presented. The decision ordering to stop the use of a household wastewater treatment plant has to be preceded by a decision ordering to take measures to limit its adverse impact on the environment. The clarification procedure has to determine the adverse impact on the environment in a doubtless manner and it has to be reflected in the documentation. The assessment of adverse impact should take into account the binding standards of use of the environment. Stopping the operation of a household wastewater treatment plant may result in issuing a decision ordering the user to connect to the sanitary sewage system.

    his study was undertaken to evaluate the possibility of disposing low-level radioactive waste in sanitary landfills with leachate containment to prevent environmental releases. To meet this objective, two simulated landfills, each 200 l. in volume and containing 55 kg of municipal refuse, were operated in the laboratory with simulated rainfall additions for a 9-month period to observe the extent to which radio-cobalt, -cesium, -strontium and tritium were leached into the liquid phase. One of the units was operated with leachate recycle, the other as a single pass control. Liquid samples were analyzed weekly for 3H, 58Co, 85Sr and 134Cs tracers. Weekly analyses were also performed for approximately 30 parameters to define the degree of stabilization of the waste. Major parameters included BOD, COD, pH and concentrations of specific organics, metals and gases. Concentrations of stable cobalt, strontium and cesium were also measured periodically. Soluble radioactivity levels in both systems were reduced by factors of 50 for 58Co, 5 for 85Sr and 7 for 134Cs, taking radioactive decay and dilution into account. Some radionuclide removal from the liquid phase was associated with major chemical changes in the landfills that occurred within 80 days for the control system and within 130 days for the recycle unit. Observed acid, sulfide, and CO2 concentrations suggested mechanisms for removing some of the radionuclides from leachate. Detection of 3H in the off-gas indicated that less than 1% of tritiated waste became airborne. The waste in the leachate recycle unit was more completely stabilized than in the control unit.

    Being cared for when sick is a benefit of sociality that can reduce disease and improve survival of group members. However, individuals providing care risk contracting infectious diseases themselves. If they contract a low pathogen dose, they may develop low-level infections that do not cause disease but still affect host immunity by either decreasing or increasing the host's vulnerability to subsequent infections. Caring for contagious individuals can thus significantly alter the future disease susceptibility of caregivers. Using ants and their fungal pathogens as a model system, we tested if the altered disease susceptibility of experienced caregivers, in turn, affects their expression of sanitary care behavior. We found that low-level infections contracted during sanitary care had protective or neutral effects on secondary exposure to the same (homologous) pathogen but consistently caused high mortality on superinfection with a different (heterologous) pathogen. In response to this risk, the ants selectively adjusted the expression of their sanitary care. Specifically, the ants performed less grooming and more antimicrobial disinfection when caring for nestmates contaminated with heterologous pathogens compared with homologous ones. By modulating the components of sanitary care in this way the ants acquired less infectious particles of the heterologous pathogens, resulting in reduced superinfection. The performance of risk-adjusted sanitary care reveals the remarkable capacity of ants to react to changes in their disease susceptibility, according to their own infection history and to flexibly adjust collective care to individual risk.

    A study into the removal of contamination load and indicator bacteria was carried out in 1992-1996 in the mechanical, biological and chemical waste-water treatment plant WTP in Lezany, in the County of Reszel, in the Province of Warmia and Mazury in Poland. The results of chemical analyses found a high efficiency of removal of carbon compounds, COD (90%) and BOD (98%), in the process of purification of household sewage. In addition, a high effectiveness of total nitrogen, on average 71%, and unsatisfactory removal of ammonia nitrogen and phosphorus compounds were found. The results of microbiological analyses confirmed the high efficiency of removal of indicator bacteria in the process of sewage treatment from 94 to 97%. In the sewage after the final phase of purification in stabilization ponds, the following pathogenic bacteria were identified with the use of the EPL 21tests: Escherichia coli, Enterobacter agglomerans, Enterobacter aerogenes, Enterobacter cloacae, Enterobacter georgoriae, Citrobacter freundii, Klebsiella pnemoniae, Klebsiella oxytoca, Klebsiella ozaenae, Ervinia herbicola, Edwardsiella tarda, Serratia odoriefra, Serratia marcescens, Providencia alcalifaciens, Hafnia alvei, Yersina pestis, Yersina pseudotuberculosis, Yersinia fredericksenii, Salmonella spp., Shigella dysenteriae, Aeromons hydrophila, Pseudomonas aerulginosa. The obtained results show that although the sewage purification system is efficient and reduces the contamination load to the level required by the regulations (Ministry of Environmental Protection, Natural Resources and Forestry from 20 September 1991) and removes a great percentage of indicator bacteria, the purified sewage may be a source of pathogenic bacteria in inland waters.

    Full Text Available Quality of life on Earth in the future will largely depend on the amount of safe water. As the most fundamental source of life, water is relentlessly consumed and polluted. To halt this trend, many countries are taking extensive measures and investing substantial resources in order to stop the contamination of water and return at least tolerably good water quality to nature. The goal of water purification is to obtain clean water with the sewage sludge as a by-product. Clean water is returned to nature, and further treatment of sludge may be subject to other procedures. The conclusion of this paper is simple. The procedure with purified water is easily achievable, purified water is discharged into rivers, lakes and seas, but the problem of further treatment of sludge remains. This paper presents the basic methods of wastewater treatment and procedures for processing the products from contaminated water. The paper can serve as a basis for further elaboration. Water Pollution In order to ensure normal life of living creatures, the water in which they live or the water they use must have a natural chemical composition and natural features. When, as a result of human activities, the chemical composition of water and the ratio of its chemical elements significantly change, we say that water is polluted. When the pollutants come from industrial plants, we are talking about industrial wastewater, and when they come from households and urban areas, we are talking about municipal wastewater. Both contain a huge amount of pollutants that eventually end up in rivers. Then, thousands of defenseless birds, fish and other animals suffer, and environmental consequences become immeasurable. In addition, the waste fed to the water often ends up in the bodies of marine animals, so they can return to us as food. Thermal water pollution also has multiple effects on the changes in the wildlife composition of aquatic ecosystems. Polluted water can be purified by

    Full Text Available Sea urchin (Paracentrotus lividus is an edible echinoderm very common in the Mediterranean sea. In the Sardinian gastronomic tradition it represents a product very used in some periods of the year, but in practice the sanitary controls by the competent authorities are very difficult. The Reg. (EC n. 853/2004 provides that, as regards as the control on production, echinoderms are assimilable to live bivalve molluscs, with the exception of the provisions on purification. In this work a proposal for the sanitary management of the phases of gathering, transport and selling of the sea urchins has been studied.

    2010-01-01

    The scientific rationale for preventive measures based on sanitary-and-epidemiological surveillance on environmental objects is considered. The sizes of functional zones and space for various types of communal services and amenities and leisure are regulated to ensure good urban vital activities. Multistorey housing causes an increase in the number of negative factors per area units and in their impact on health. A proposal has been made for the standardization of the ranges of urban population upsurge and size, by using the sanitary-and-hygienic rules and norms rather than climatic parameters. A criterion system for assessing the data of statistical observations has been substantiated and 5 levels of analysis and managerial decision-making have been proposed. Cause-and-effect relations may be determined for the parameters of the second level; models of program-oriented studies for the third level, only sanitary-and-epidemiological surveillance is possible for the fourth and fifth levels. The space planning scheme must provide for water supply reserves, generation areas for pure air coming into the town, and waste disposal areas. The general layout may use statistical observation parameters characterizing the second level of occurrence of negative phenomena. The statistical observation parameters characterizing the third and fourth levels of occurrence of negative phenomena may be used for municipal improvements and sanitary maintenance. These characterizing the fourth and fifth level may be used for prevention in therapeutic-and-prophylactic institutions.

    Full Text Available In the article the short historical review on the design of sanitary rooms and their configurations is given. The main errors of the recent years, which led to the decrease in accommodation convenience because of the wrong approach from both the architect and engineers, are given. It is possible to use a small useful area for sanitary facilities, but it is connected with the lack of possibility of connecting washing and dishwashers. The author considers the options of engineering equipment placement in sanitary rooms taking into account the convenience of use, safety, and also resource-saving aspect. Various solutions on the organization of heating and ventilation are provided. The possible technical solutions allowing solving a flooding problem of the first floors in elite housing estates in case of accident are offered with the help of full waterproofing of sanitary rooms, and also the whole area of the apartment. The main attention was focused on the improvements of sanitary rooms for one-room and two-room apartments, which are the most demanded in the modern market of real estate. Layout solutions of the reduced bathrooms on the placement of the necessary equipment with choice justification are provided. The attention is paid to the layout solution for modern kitchens on order to increase their comfort by the use of special two-section sinks, and also a grinder of food waste in order to allow to lower the load of the systems of rubbish disposal of a building, by dumping the crushed garbage in an internal sewer network. Various options of evolutionary development of sanitary rooms for increasing the comfort degree are given. First of all, the development should happen in the direction of not only sanitation and hygiene, but also of the maintenance of the physical health of the people living in the building. It can be carried out by increase in a useful area of sanitary rooms, installation of exercise machines, medical bathtubs and a Jacuzzi

    2009-12-01

    To assess the performance of SBR to treat three different types of wastewater from domestic, hospital, slaughterhouse and investigate the kinetic rates of active biomass. Mass balance calculation of COD, TKN and TP was further performed to explain the mechanisms of the biological nutrient removals processed in the SBR system. The measured kinetic rates were in turn used to evaluate the process performances under different types of wastewater. Experimental research involving 3 similar SBR lab-scales were installed and operated at the Sanitary Engineering Laboratory. The reactors were seeded with sludge biomass obtained from the Sri-Phraya Domestic Wastewater Treatment Plant in Bangkok. The slaughterhouse, hospital and domestic wastewaters were treated by SBR system for biological organic carbon (COD), nitrogen (TKN) and phosphorus removals. Biological methods for kinetic rates evaluation were conducted in five replicated batch tests. The removal efficiencies of COD and TKN were greater than 90% for all three types of wastewater while the biological phosphorus removal for domestic and hospital wastewaters were less than 60% and phosphorus removal for slaughterhouse exceeded 95%. The kinetic rates of nitrification and denitrification of hospital wastewater was lower than those the domestic and slaughterhouse wastewaters. Phosphorus release and uptake rates of slaughterhouse wastewater were high but domestic and hospital wastewaters were very low. The result of system removal efficiency and batch test for kinetic rates confirmed that the domestic and hospital wastewaters were in deficiency of organic carbon with respect to its ability to support successful biological phosphorus removal.

    Antonio Lonigro

    2007-07-01

    Full Text Available In this paper the utility of the treated municipal wastewaters in agriculture, analyzing the chemical, physical and microbiological characteristics and their pollution indicators evaluation are being illustrated. Some methods employed for treating wastewaters are examined, as well as instructions and rules actually in force in different countries of the world, for evaluating the legislative hygienic and sanitary and agronomic problems connected with the treated wastewaters use, are being collected and compared. Successively, in order to provide useful indications for the use of treated municipal wastewaters, results of long-term field researches, carried out in Puglia, regarding two types of waters (treated municipal wastewater and conventional water and two irrigation methods (drip and capillary sub-irrigation on vegetable crops grown in succession, are being reported. For each crop cycle, chemical physical and microbiological analyses have been performed on irrigation water, soil and crop samples. The results evidenced that although irrigating with waters having high colimetric values, higher than those indicated by law and with two different irrigation methods, never soil and marketable yield pollutions have been observed. Moreover, the probability to take infection and/or disease for ingestion of fruits coming from crops irrigated with treated wastewaters, calculated by Beta-Poisson method, resulted negligible and equal to 1 person for 100 millions of exposed people. Concentrations of heavy metals in soil and crops were lesser than those admissible by law. The free chlorine, coming from disinfection, found in the wastewaters used for watering, in some cases caused toxicity effects, which determined significant yield decreases. Therefore, municipal wastewaters, if well treated, can be used for irrigation representing a valid alternative to the conventional ones.

    2002-01-01

    Last July the a new legal Rule concerning Sanitary Protection against Ionising Radiation was published, as a transposition of the EU Directive about the Basic Norms related to the sanitary protection of workers and population against the risks resultant of the ionising radiation. The origin of this legislation goes back to the revision of the protection doctrine by the International Commission of Radiation Protection (ICRP) en the year 1990. El scope of the revised Rule is the regulation of the protection of population and workers against ionising radiation, the establishment of the national protection system with its exposition and dose limits and the correspondent penalty regime. It also modifies the maximum radiation dose limits and reinforces the application of the optimisation principle in the use of ionising radiation. In this article, the novelties introduced by the new Rule are commented in detail, ordered by the Titles I to IX in which the Rule is divided. (Author)

    2006-07-01

    Full Text Available The aim of the paper was to evaluate sanitary condition of food preparation and distribution in the "Public kitchen" in Nis, as well as the meals’ quality in order to assess the health risks. The local inspection of the objects and microbiological analysis of swaps were done according to standard methods. Energetical values and biochemical structure of the meals were assessed by bromatological methods and energetical density was calculated. The study was being conducted from 2002 – 2005. The results show that sanitary conditions in the object were not adequate, because of a high percentage of incorrect samples (13.4% from the total number of samples. Energetical values of meals were usually adequate (1157 – 1564 kcal, 4837 – 6581 kJ, but constantly decreased. The chemical structure of the meals was adequate too, meaning that meals were very well- planed. The energetic density of meals was high (1,18 – 1,42 kcal/g. Our conclusion is that there are no alternatives to continuous health care education of the medical stuff and regular sanitary hygienic control, all with the aim to accomplish complete social function of the public kitchen and to protect the health of its consumers.

    Waste disposal represents an important problem in developed countries. Many different techniques are available to reduce the amount of waste production and its environmental impact. In most cases, sanitary landfills have been and continue to be one of the most common ways to dispose of urban and industrial wastes. It is well known how landfilling produces an important environmental drawback due to gaseous, liquid and solid emissions that are dangerous for the environment. Landfill biogas emissions contain mainly carbon dioxide and methane. In particular, the methane concentration can be higher than 50% by volume. This means that the calorific value of sanitary landfill biogas can be higher than 18,000 kJ/N m 3 . The utilization of such gas as fuel for electrical and thermal energy production can be an important way to reduce the landfill impact on the environment and represent an easy way to use a renewable energy source. In the following, the amount and composition of the biogas produced in a sanitary landfill situated in central Italy have been analysed. Experimental results have been discussed, and an energetic potential evaluation has been performed

    The first formally adopted regulatory policy for irradiation as a phyto sanitary treatment in the United States was issued in 1989 and was based on Title 7 of the Code of Federal Regulations. These regulations authorized irradiation as a quarantine treatment for papayas intended for movement from the State of Hawaii to the continental United States (U.S.), Guam, Puerto Rico, and the U.S. Virgin Islands. This authorization was specific for commodity, place of origin, and program, but was designed for a complex of three fruit flies rather than a single pest. Routine commercial shipments were never realized under this regulation due to the lack of a treatment facility in Hawaii. However, the authorization has proven useful from the standpoint of beginning to establish policies for irradiation as a phyto sanitary treatment in the United States. The United States Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS), Plant Protection and Quarantine (PPQ) remains dedicated to using the most up-to-date, appropriate and least intrusive technology to provide quarantine security. The need for alternative treatments for pests mitigation systems is greater than ever. Global trade pressures and the possible loss of methyl bromide make it imperative that all practical treatment options be explored. Since 1989 irradiation treatment concepts have matured significantly. Technological advances, greater experience, and an increasingly larger body of research indicate that irradiation has important potential as a treatment for quarantine pest problems. It is in this light that PPQ is expanding its regulatory framework, is addressing irradiation treatment options, and is developing comprehensive policy statements intended to facilitate the development and formalization of new treatments for phyto sanitary applications.

E-mail: jeanberg@ufersa.edu.br The aim of this study was to evaluate hygienic and sanitary conditions of municipal slaughterhouses in Rio Grande do Norte. Through a check list, hygienic conditions of establishments and handlers were observed and the percentage of compliance was rated excellent (≥ 80%, good (60 to 79.9%, regular (40 to 59.9% and poor (<40%, according to official standards established by Brazilian legislation. Ten water samples were collected to analyze total and thermotolerant coliforms; and 200 swab samples, including 150 from the utensils, equipment, handlers, and cattle carcasses were investigated for Staphylococcus aureus and Enterobacteria, and 50 from the environment for Listeria sp. research. It was noted, through the check list, the existence of various inadequate parameters when compared to those established, and required by law. According to the percentage of compliance found in abattoirs during the assessment visits, no slaughterhouse was rated as excellent, only one was considered good, one was classified as regular and three were considered poor. As for the microbiological analyzes, the presence of coliforms was confirmed in water from two slaughterhouses. High bacteria counts were found in swabs from tools, handlers, and cattle carcasses, and the presence of Listeria sp. was observed in three slaughterhouses. Therefore, the precarious sanitary conditions of the municipal slaughterhouses studied in Rio Grande do Norte represent a risk to

    The first formally adopted regulatory policy for irradiation as a phyto sanitary treatment in the United States was issued in 1989 and was based on Title 7 of the Code of Federal Regulations. These regulations authorized irradiation as a quarantine treatment for papayas intended for movement from the State of Hawaii to the continental United States (U.S.), Guam, Puerto Rico, and the U.S. Virgin Islands. This authorization was specific for commodity, place of origin, and program, but was designed for a complex of three fruit flies rather than a single pest. Routine commercial shipments were never realized under this regulation due to the lack of a treatment facility in Hawaii. However, the authorization has proven useful from the standpoint of beginning to establish policies for irradiation as a phyto sanitary treatment in the United States. The United States Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS), Plant Protection and Quarantine (PPQ) remains dedicated to using the most up-to-date, appropriate and least intrusive technology to provide quarantine security. The need for alternative treatments for pests mitigation systems is greater than ever. Global trade pressures and the possible loss of methyl bromide make it imperative that all practical treatment options be explored. Since 1989 irradiation treatment concepts have matured significantly. Technological advances, greater experience, and an increasingly larger body of research indicate that irradiation has important potential as a treatment for quarantine pest problems. It is in this light that PPQ is expanding its regulatory framework, is addressing irradiation treatment options, and is developing comprehensive policy statements intended to facilitate the development and formalization of new treatments for phyto sanitary applications.

    Planning, construction and operation of onsite wastewater treatment systems at mountain refuges is a challenge. Energy supply, costly transport, limited water resources, unfavourable climate and load variations are only some of the problems that have to be faced. Additionally, legal regulations are different between and even within countries of the Alps. To ensure sustainability, integrated management of the alpine infrastructure management is needed. The energy and water supply and the wastewater and waste disposal systems and the cross-relations between them were analysed for 100 mountain refuges. Wastewater treatment is a main part of the overall 'mountain refuge' system. The data survey and first analyses showed the complex interaction of the wastewater treatment with the other infrastructure. Main criteria for reliable and efficient operation are training, technical support, user friendly control and a relatively simple system set up. Wastewater temperature, alkalinity consumption and high peak loads have to be considered in the planning process. The availability of power in terms of duration and connexion is decisive for the choice of the system. Further, frequency fluctuations may lead to damages to the installed aerators. The type of water source and the type of sanitary equipment influence the wastewater quantity and quality. Biosolids are treated and disposed separately or together with primary or secondary sludge from wastewater treatment dependent on the legal requirements. IWA Publishing 2008.

    For the 2014 World Cup and the 2016 Olympic Games, Brazil has expanded its airport infrastructure. This will lead to an increase in wastewater generation from aircrafts. This wastewater is traditionally taken from the aircrafts and disposed in the public sewage collection system. However, this residual water may have a different composition than the usual sanitary sewage. Therefore, it is important to study an alternative to treat this kind of wastewater. Thus, the objective of this study was to characterize and analyze the treatment of wastewater from airplane toilets through chemical precipitation for the removal of ammonia in the form of struvite. The airplanes' effluent showed a composition similar to human urine with pH 8.9, ammonia nitrogen 4,215 mg L -1 , phosphorus 430 mg L -1 and a very high acute toxicity (Vibrio fischeri). The best treatment for struvite formation was with pH 9.0 and molar ratio Mg:NH 4 :PO 4 equal to 1.5:1.0:1.0. In this case, the removal of ammonia and phosphorus achieved 97.0% and 95.3%, respectively. After this procedure, the toxicity by Vibrio fischeri decreased.

    Population densities and freshwater resources are not evenly distributed worldwide. This has forced farmers to use wastewater for the irrigation of food crops. This practice presents both positive and negative effects with respect to agricultural use, as well as in the context of environmental contamination and toxicology. Although wastewater is an important source of essential nutrients for plants, many environmental, sanitary, and health risks are also associated with the use of wastewater for crop irrigation due to the presence of toxic contaminants and microbes. This review highlights the harmful and beneficial impacts of wastewater irrigation on the physical, biological, and chemical properties of soil (pH, cations and anions, organic matter, microbial activity). We delineate the potentially toxic element (PTEs) build up in the soil and, as such, their transfer into plants and humans. The possible human health risks associated with the use of untreated wastewater for crop irrigation are also predicted and discussed. We compare the current condition of wastewater reuse in agriculture and the associated environmental and health issues between developing and developed countries. In addition, some integrated sustainable solutions and future perspectives are also proposed, keeping in view the regional and global context, as well as the grounded reality of wastewater use for crop production, sanitary and planning issues, remedial techniques, awareness among civil society, and the role of the government and the relevant stakeholders.

    Land application is one of the best options for the elimination of wastewater sludge, because sludge is useful as conditioner and fertilizer in soils. However, land application represents a sanitary hazards due to the sludge's content in pathogenic agents. Helminth eggs are among these agents, and their hardness and resistance to adverse environmental conditions allows them to survive in soils for months. With this in mind, we have launched a study of the presence of helminth eggs in the sludge of a wastewater treatment plant in Alboraia (Valencia). The results show a concentration of helminth eggs in digestion sludge of 27.000 eggs/kg dry matter. We discuss the potential sanitary relevant of these results and the need to continue with this evaluation program. (Author) 20 refs.

    The environmental risks and uncertainties of a high-energy future are disturbing and give rise to several reservations concerning the use of fossil fuels. A number of technologies will help to reduce atmospheric pollution. In Denmark special importance is attached to the following: Energy conservation. Efficient energy conversion. Renewable energy sources. District heating, combined production of heat and power. Many agree that district heating (DH), produced by the traditional heat-only plant, and combined heat and power (CHP) have enormous potential when considering thermal efficiency and lowered environmental impacts: The basic technology of each is proven, it would be relatively simple to satisfy a substantial part of the energy demand, and their high efficiencies mean reduced pollution including greenhouse gas emissions. This is especially important in high population density areas - the obviously preferred sites for such energy generation. Compared with individual heating DH can provide a community with an operationally efficient and most often also an economically competitive heat supply. This is particularly true under the circumstances where the DH system is supplied from CHP plants. Their use results in very substantial improvements in overall efficiency. Further environmental improvements arise from the reduced air pollution obtainable in reasonably large CHP plants equipped with flue gas cleaning to remove particles, sulphur dioxide, and nitrogen acids. As a consequence of these considerations, DH plays an important role in fulfilling the space and water heating demand in many countries. This is especially the case in Denmark where this technology is utilised to a very great extent. Indeed, DH is one of the reasons why Denmark has relatively good air quality in the cities. (au)

  4. The sanitary effect of gamma irradiation on sewage sludge

    1975-01-01

    Sludge contains Salmonellae in more than 90% of samples. The maximum number reaches 10 7 per liter. Neither aerobic stabilization nor anaerobic digestion significantly reduces the contamination with Salmonellae. Moreover, Salmonellae in sewage sludge spread on grass may survive up to 72 weeks. Fertilizing with unsanitized sludge may therefore lead to transmission from plant to animal. Sanitizing of sludge to be used as fertilizer is therefore urgent. The sanitary effect of pasteurisation and of gamma irradiation on sewage sludge was investigated. For this the number of Enterobacteriaceae before and after irradiation in 259 specimens of sludge from 44 different sewage disposal plants was examined. The doses applied were 100, 200, 300, 400 and sometimes 500 krad. A linear reduction of Enterobacteriaceae was achieved with increasing radiation doses. A dose of 300 krad resulted in a death rate of 10 4 - 10 8 , occasionally 10 9 Enterobacteriaceae. Less than 10 Enterobacteriaceae per gramm were found in 97.2% of the samples irradiated with 300 krad. The effect found in the above mentioned model experiments could be perfectly confirmed under practical conditions in the irradiation plant of Geiselbullach. The sanitary effect of gamma irradiation with 300-350 krad, determined by Enterobacteriaceae reduction, was equivalent to the effect of heat treatment by pasteurisation. (orig./MG) [de

These wells are sampled semiannually to comply with the South Carolina Department of Health and Environmental Control Modified Municipal Solid Waste Permit 025500-1120 and as part of the SRS Groundwater Monitoring Program. Trichlorofluoromethane and 1,1,1-trichloroethane were elevated in one sidegradient well and one downgradient well during 1996. Zinc was elevated in three downgradient wells and also was detected in the associated laboratory blanks for two of those wells. Specific conductance was elevated in one background well and one sidegradient well. Barium and copper exceeded standards in one sidegradient well, and dichloromethane (a common laboratory contaminant) was elevated in another sidegradient well. Barium, copper, and dichloromethane were detected in the associated blanks for these wells, also. The groundwater flow direction in the Steed Pond Acquifer (Water Table) beneath the Interim Sanitary Landfill was to the southeast (universal transverse Mercator coordinates). The flow rate in this unit was approximately 210 ft/year during first quarter 1996 and 180 ft/yr during third quarter 1996

    This paper presents the effect of wastewaters on properties of Portland pozzolana cement (PPC). Fourteen water treatment plants were found out in the Narasaraopet municipality region in Guntur district, Andhra Pradesh, India. Approximately, from each plant, between 3500 and 4000 L/day of potable water is selling to consumers. All plants are extracting ground water and treating through Reverse Osmosis (RO) process. During water treatment, plants are discharging approximately 1,00,000 L/day as wastewater in side drains in Narasaraopet municipality. Physical and chemical analysis was carried out on fourteen plants wastewater and distilled water as per producer described in APHA. In the present work, based on the concentrations of constituent's in wastewater, four typical plants i.e., Narasaraopeta Engineering College (NECWW), Patan Khasim Charitable Trust (PKTWW), Mahmadh Khasim Charitable Trust (MKTWW) and Amara (ARWW) were considered. The performance of four plants wastewater on physical properties i.e., setting times, compressive strength, and flexural strength of Portland pozzolana Cement (PPC) were performed in laboratories and compared same with reference specimens i.e., made with Distilled Water (DW) as mixing water. No significant change was observed in initial and finial setting time but setting times of selected wastewaters were retarded as compared to that of reference water. Almost, no change was observed in 90 days compressive and flexural strengths in four plants wastewaters specimens compared to that of reference water specimens. XRD technique was employed to find out main hydration compounds formed in the process.

    Our investigations prove that sludge contains Salmonellae in more than 90% of samples. The maximum number of organisms was 10 7 per litre. One of our most important findings was the fact that neither aerobic stabilization nor anaerobic digestion significantly reduces contamination with Salmonellae. Moreover we found that Salmonellae in sewage sludge spread on grass may survive up to 72 weeks. Fertilizing with unsanitized sludge may therefore lead to transmission from plant to animal. The increasing number of Salmonella carriers among our herds of cattle and their striking accumulation during the grazing period demonstrate that such transmission represents a growing danger. Sanitation of sludge to be used as fertilizer is therefore urgent. In our investigation of the sanitary effect of pasteurization (70degC for 30 min) and of gamma irradiation on sewage sludge, we examined the number of Enterobacteriaceae before and after irradiation in 259 specimens of sludge from 44 different sewage disposal plants. The doses applied were 100, 200, 300, 400 and also 500 krad. We found a linear reduction of Enterobacteriaceae with increasing doses; a dose of 300 krad resulted in a death rate of 10 4 - 10 8 , occasionally 10 9 Enterobacteriaceae; and there were less than 10 Enterobacteriaceae per gram in 97.2% of the samples irradiated with 300 krad. The results of these model experiments could be completely confirmed under practical conditions in the irradiation plant of Geiselbullach. The sanitary effect of gamma irradiation with 300-350 krad, determined by the reduction in Enterobacteriaceae, was equivalent to the effect of heat treatment by pasteurization. (author)

Their excess concentrations in water receiving bodies lead to eutrophication, moreover, the nitrogen content in water bodies is standardized according the sanitary-toxicological criterion of harmfulness: NH 4 + -N ≤0,39-2,0 mgl - , NO 3 -N ≤9,1-10 mgl - . The municipal wastewater contain, usually, organic matter estimated by BOD 150-200 mgl - , and COD 300-400 mgl - , the nitrogen compounds 50-60 mgl - , and NH 4 + -N 20-25 mgl - . NO x -N are practically absent. Their presence indicated on discharge of industrial wastewater. The total phosphorus is present in the concentration of 15 mgl - , PO 4 - - P 5-8 mgl - . Activated sludge process has been most widely used in the USSR for municipal wastewater treatment. The activated sludge is biocenoses of heterotrophic and auto trophic microorganisms. They consume nutrient matters, transferring pollution of wastewater by means of enzyme systems in acceptable forms. C, N and P-containing matters are removed from wastewater by biological intake for cell synthesis. Moreover C- containing matters are removed by oxidation to CO 2 and H 2 O. P-containing compounds under definite conditions associate with solid fraction of activated sludge and thus simultaneously removed from wastewater. The removal of nitrogen in addition to biosynthesis is carried out only in the denitrification process, when oxygen of NO x -N is used for oxidation of organic matter and produced gaseous nitrogen escapes into the atmosphere

    Full Text Available The results of the comparative assessment of the sanitary and epidemiological quality of the ambient air in Moscow and the Russian Federation, that demonstrate a decrease of the air pollution level in 2014 in comparison with 2012, both in Moscow and in the Russian Federation, are presented in this study. It has been noted that most of the excess of hygienic air quality standards in the areas of Russian cities are recorded on stationary observation stations situated close to the motorway, located in residential areas, and in Moscow – in the zones of industrial enterprises’ impact. It has been revealed that the tendency to the reduction of the negative impact from industrial enterprises on air pollution is registered in the whole of the Russian Federation and in Moscow. It is demonstrated that the high-priority contaminating agents, the content of which for the year 2014 in the Russian Federation exceeded the hygienic daily average standards in 5 and more times, are mainly: benzo (a pyrene, suspended substances, sulfur dioxide, benzene, formaldehyde, nitrogen dioxide, hydrogen sulfide, etc. To assess the quality of the ambient air in Moscow, the method of "inverse distance" and inter- and extrapolation of the data obtained from the observation stations on the whole territory of Moscow has been used. The study shows that the air quality of the individual administrative districts of Moscow varies considerably, and is determined by the traffic load level as well as by the volume of emissions of the industrial enterprises and the wind rose. As high-priority contaminating agents affecting the air quality, nitrogen dioxide, ammonia, benzene, suspended substances, ozone and formaldehyde are distinguished. It is noted that close to the highway near Moscow there is an excessive concentration of nitrogen dioxide, formaldehyde, phenol, and carbon monoxide, and in areas close to industrial zones – nitrogen dioxide, phenol formaldehyde and benzo (a

    The major objectives of this investigation are: (1) to study the attenuation mechanisms for radionuclides (LLRW) in simulated sanitary landfills with and without leachate recycle; and (2) to determine the complexation potential of ligands (viz., sulfides, humic substances) present in the leachate during different stages of landfill stabilization. Since the major emphasis of this research is on containment and isolation of LLRW within a sanitary landfill the following key elements have been incorporated into the design of the simulated pilot-scale sanitary landfills: (1) containment of LLRW within the landfills by placing the municipal refuse and LLRW in polymeric membrane-lined cells (30-mil, HDA, Gundline liner, Gundle, TX) with a leachate collection system; (2) enhancement of stabilization by leachate recycle; and (3) recovery of the gas produced from the sanitary landfills. The proposed research program addresses the fate of LLRW in municipal sanitary landfills thereby, establishing a data base to predict radionuclide pathways in sanitary landfills and to aid in assessing the environmental impacts of codisposal of LLRW within sanitary landfills. The outcome of this study may also serve to alleviate the current concern of unnecessary filling of limited space in existing licensed shallow-land burial sites. 4 figures, 1 table

  1. Narratives of Public Health in Dickens's Journalism: The Trouble with Sanitary Reform.

    Science.gov (United States)

    Smith, Ralph F

    2015-01-01

    Although Dickens is still known as having been a highly visible supporter of England's well-known nineteenth-century sanitary movement, he became, in fact, deeply troubled by many of this movement's fundamental tenets, as evidenced by journal narratives on fever that he edited and wrote in the mid-nineteenth century. Rather than water and sewer engineering works and a sanitary regime policed by government agencies as envisaged by Edwin Chadwick and other sanitary reformers, Dickens's view by 1855 was that only a massive erasure of the existing social and political systems and their replacement by an utterly new infrastructure would suffice.

  2. Leachate treatment system using constructed wetlands, Town of Fenton sanitary landfill, Broome County, New York. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1993-11-01

    Municipal sanitary landfills generate leachate that New York State regulations require to be collected and treated to avoid contaminating surface water and groundwater. One option for treating leachate is to haul it to municipal wastewater treatment facility. This option may be expensive, may require excessive energy for transportation, and may require pretreatment to protect the receiving facility`s processes. An alternative is on-site treatment and discharge. Personnel from the Town of Fenton, New York; Hawk Engineering, P.C.; Cornell University; and Ithaca College designed, built, and operated a pilot constructed wetland for treating leachate at the Town of Fenton`s municipal landfill. The system, consisting of two overland flow beds and two subsurface flow beds has been effective for 18 months in reducing levels of ammonia (averaging 85% removal by volatilization and denitrification) and total iron (averaging 95% removal by precipitation and sedimentation), two key constituents of the Fenton landfill`s leachate. The system effects these reductions with zero chemical and energy inputs and minimal maintenance. A third key constituent of the leachate, manganese, apparently passes through the beds with minimal removal. Details and wetland considerations are described.

  3. Environmental impacts of wastewater from urban slums: case study - Old Fadama, Accra

    2013-06-01

    Full Text Available The burgeoning of slums in the developing world poses an urgent environmental threat due to insanitary conditions and rampant disposal of wastewater. To assess the potential environmental impacts, domestic wastewater from Ghana's biggest urban slum - Old Fadama was characterised throughout the dry and wet seasons. The study drew on a comprehensive assessment of the general sanitary conditions in the community to determine the sources of pollution and water quality monitoring. BOD5 levels of wastewater from the study area were 545.63±99.88mg/L and 645.94±331.43mg/L in the dry and wet seasons respectively whereas COD levels were 1100.45±167.16mg/L and 1415.12±722.83mg/L in the dry and wet seasons respectively. E-coli levels were 4±1x106CFU/100mL and 4200±2400 x106CFU/100mL in the dry and wet seasons respectively whereas total coliform levels also showed the same trend with 9±2106CFU/100mL and 16800±5100106CFU/100mL in the dry and wet seasons respectively. The study identifies that wastewater from this community has potential deleterious environmental implications due to high levels of nutrients, oxygen-demanding substances and faecal coliforms. Pollutants were identified to be emanating predominantly from open defecation and indiscriminate waste disposal. Efforts should thus be directed towards improving sanitary conditions viz. access to toilet facilities, waste disposal mechanisms and best management practices for wastewater.

    An experimental study was carried out in order to evaluate the possibility of upgrading the conventional activated sludge WWTP of Seano (Prato, Italy) which treats municipal and textile wastewaters, by using membrane bioreactor (MBR) technology. The MBR pilot plant, set up within Seano WWTP, was fed with mixed municipal-industrial wastewaters during the first experimental period and with pure industrial wastewaters during the second. Performances and operation of the MBR were evaluated in terms of permeate characteristics and variability (COD, colour, surfactants, total N and P) and other operational parameters (sludge growth and observed yield). According to the experimental results the MBR permeate quality was always superior to the Seano WWTP one and it was suitable for industrial reuse in the textile district of the Prato area. Respirometric tests provided a modified IWA ASM1 model which fits very well the experimental data and can be used for the design and the monitoring of a full-scale MBR pilot plant.

    1992-09-01

    A heat recovery system is described with a heat exchanger and a mixing valve. A drain trap includes a heat exchanger with an inner coiled tube, baffle plate, wastewater inlet, wastewater outlet, cold water inlet, and preheated water outlet. Wastewater enters the drain trap through the wastewater inlet, is slowed and spread by the baffle plate, and passes downward to the wastewater outlet. Cold water enters the inner tube through the cold water inlet and flows generally upward, taking on heat from the wastewater. This preheated water is fed to the mixing valve, which includes a flexible yoke to which are attached an adjustable steel rod, two stationary zinc rods, and a pivoting arm. The free end of the arm forms a pad which rests against a valve seat. The rods and pivoting arm expand or contract as the temperature of the incoming preheated water changes. The zinc rods expand more than the steel rod, flexing the yoke and rotating the pivoting arm. The pad moves towards the valve seat as the temperature of the preheated water rises, and away as the temperature falls, admitting a variable amount of hot water to maintain a nearly constant average process water temperature. 6 figs.

  13. Sanitary-epidemiological audit in russia and abroad: challenges and growth prospects (analytical review

    Directory of Open Access Journals (Sweden)

    I.V. May

    2016-12-01

    Full Text Available The shaping the system of control and surveillance activities in the Russian Federation, which affects the bodies of the sanitary-epidemiological surveillance, requires the development of new forms of cooperation between authorities and legal entities, individual entrepreneurs and population. Such a form may be represented by the sanitary and epidemiological audit as an independent objective assessment of reputable third parties. The audit is intended to check the compliance with the mandatory requirements of the economic entities, performing economic or other activities. The sanitary-epidemiological audit may be associated with a system of certification for compliance with sanitary requirements and may assume the documented confirmation of the compliance issued by the authorized persons. The sanitary-epidemiological audit and the compliance certification to mandatory sanitary requirements can make an alternative to the planned supervision activities on facilities attributed to the category of low and moderate risk of harm to human health. The Russian sanitary legislation does not recognize the sanitary-epidemiological audit as a form of conformity assessment. The analysis of the international experience shows that it is necessary to consolidate the general rules and regulations of the sanitary-epidemiological audit at the legislative level and to develop a set of sublegislative documents in order to implement these norms. The crucial is a creation of the national system capable to regulate the registration and functioning of the organization having a right to conduct the audit activities in the field of hygienic safety. It is reasonable to develop the regulation on the list-register of auditors and to create a special training system for the auditors, who possess the methodology for health risk assessment. The key aspect of the successful introduction of the audit is a granting of presences to the economic entities having compliance

    1991-01-01

    District heating has been used in Switzerland for more than 50 years. Its share of the heat market is less than 3% today. An analysis of the use of district heating in various European countries shows that a high share of district heating in the heat market is always dependent on ideal conditions for its use. Market prospects and possible future developments in the use of district heating in Switzerland are described in this paper. The main Swiss producers and distributors of district heating are members of the Association of District Heating Producers and Distributors. This association supports the installation of district heating facilities where ecological, energetical and economic aspects indicate that district heating would be a good solution.

    Full Text Available Minas Gerais is the largest one out of the four states that comprise the southeastern region of Brazil, with the bigest goat herd of this region. The characterization of health aspects of dairy goat husbandry was done in 84 dairy herds in 81 municipalities and 200 beef herds in 70 municipalities in the State of Minas Gerais. A questionnaire was filled out for each herd, requesting data regarding the farm, the herd and the farmer by the veterinarians within the Agriculture and Livestock Institute of Minas Gerais (Instituto Mineiro de Agropecuária – IMA. A data bank was developed in Windows Excel and analyzed using the Epi-Info system. Comparisons of categorical variables were based on Chi-square test. The individual identification of the animals was done at 73.8% of dairy farms and at 7.5% of beef farms, use of quarentine at 15.5% and 4.0%, isolation of sick animals at 30.9% and 11.0%, requisition of sanitary certificate in the acquisition of new animals at 28.6% and 1.5%, regular veterinary monitoring at 52.4% and 1.5%, respectively. The main health problems reported at dairy and beef farms, respectively, were abortion (50.0% and 49.5%, mastitis (41.7% and 19.0%, pneumonia (37.4% and 16.5%, diarrhea (34.5% and 16.5% and caseous lymphadenitis (20.2% and 43.0%.

    Palestinian inhabitants have disposed of their solid wastes at open dumpsites over the past 40 years without an adequate solid waste management (SWM) plans. Recently, the Palestinian Authority initiated SWM planning to establish controlled sanitary landfills, based on a participatory approach. The purpose of this study was to assess public concerns about existing solid waste dumpsites and public perceptions of sanitary landfill site selection. The study will also take into consideration the effect of diverse social, economic, and environmental related factors of the inhabitants on sitting suitable landfill sites in three Palestinian districts in the West Bank, namely, "Nablus," "Salfit," and "Ramallah and Al-Bireh." The results of this study showed that 64.9% of the sample population are aware of the problems and potential impacts associated with random dumpsites, and 41.6% think that they are suffering from the dumps. Among the environmental, socioeconomic, and political factors, the environmental factors, air pollution in particular, are thought be the most important consideration in selecting a landfill site. The "fairness in selecting a landfill site" was chosen to be one of the most important socioeconomic factors, possibly as a reaction to the Israeli occupation and subsequent land use restrictions in the West Bank, Palestinian territory.

    The outsourcing informal home practices adopted in jewelry and fashion jewelry chain can cause toxic substance elimination in the effluents and raise a concern for its environmental impact. This study evaluates if this informal work alters the concentration of potentially toxic elements (PTEs: As, Cd, Cr total and Cr-VI, Cu, Hg, Ni, Pb, Sn, and Zn) in the sewage network. The sanitary sewage samples (n = 540) were collected in 15 manholes during two campaigns in three different areas of Limeira-SP, Brazil (industrial area, with informal work and without known industrial/informal activity). The sewage sludge (n = 12), raw (n = 12), and treated sewage (n = 12) were collected in two wastewater treatment plants (WWT: AS and TATU) operating with different treatment process. The PTE determination was performed by ICP-OES, direct mercury analysis, and UV-Vis spectroscopy. Cr-VI, Cu, Ni, and Zn were the only elements above the quantification limit. Four samples exceeded Cu or Zn values permitted to be discharged into sewage system; however, the concentration average was lower than that established by Brazilian legislation. A difference was found between values above and below the 75th percentile for campaign and total organic carbon values (p < 0.015). The AS-treated sewage presented low concentrations of Cu (p < 0.05), Zn (p = 0.02), and Ni (p = 0.01) compared to treated sewage from TATU. In the sludge samples, the Cu means exceeded the limits of the Brazilian legislation (1500 mg kg -1 ) and the Zn results were very close to the limits (2800 mg kg -1 ). The heterogeneity of the results can indicate the sporadic nature of the PTE's sanitary disposal. PTEs used in jewelry and fashion jewelry chain may precipitate on the sludge, where presented high concentrations of Cu and Zn which require controlled destination.

  12. Domestic hot water storage: Balancing thermal and sanitary performance

    International Nuclear Information System (INIS)

    Armstrong, P.; Ager, D.; Thompson, I.; McCulloch, M.

    2014-01-01

    Thermal stratification within hot water tanks maximises the availability of stored energy and facilitates optimal use of both conventional and renewable energy sources. However, stratified tanks are also associated with the proliferation of pathogenic bacteria, such as Legionella, due to the hospitable temperatures that arise during operation. Sanitary measures, aimed at homogenising the temperature distribution throughout the tank, have been proposed; such measures reduce the effective energy storage capability that is otherwise available. Here we quantify the conflict that arises between thermodynamic performance and bacterial sterilisation within 10 real world systems. Whilst perfect stratification enhances the recovery of hot water and reduces heat losses, water samples revealed significant bacterial growth attributable to stratification (P<0.01). Temperature measurements indicated that users were exposed to potentially unsanitary water as a result. De-stratifying a system to sterilise bacteria led to a 19% reduction in effective hot water storage capability. Increasing the tank size to compensate for this loss would lead to an 11% increase in energy consumed through standing heat losses. Policymakers, seeking to utilise hot water tanks as demand response assets, should consider monitoring and control systems that prevent exposures to unsanitary hot water. - Highlights: • Domestic hot water tanks are a potential demand side asset for power networks. • A preference for bacterial growth in stratified hot water tanks has been observed. • Temperatures in base of electric hot water tanks hospitable to Legionella. • Potential exposures to unsanitary water observed. • De-stratifying a tank to sterilise leads to reduced energy storage capability

In its surroundings live circa 16 million inhabitants, out of which 6 million live in Rio de Janeiro city, one of the largest cities of the country, and the host of the 2016 Olympic Games. Anthropogenic interference in Guanabara Bay area started early in the XVI century, but environmental impacts escalated from 1930, when this region underwent an industrialization process. Herein we present an overview of the current environmental and sanitary conditions of Guanabara Bay, a consequence of all these decades of impacts. We will focus on microbial communities, how they may affect higher trophic levels of the aquatic community and also human health. The anthropogenic impacts in the bay are flagged by heavy eutrophication and by the emergence of pathogenic microorganisms that are either carried by domestic and/or hospital waste (e.g., virus, KPC-producing bacteria, and fecal coliforms), or that proliferate in such conditions (e.g., vibrios). Antibiotic resistance genes are commonly found in metagenomes of Guanabara Bay planktonic microorganisms. Furthermore, eutrophication results in recurrent algal blooms, with signs of a shift toward flagellated, mixotrophic groups, including several potentially harmful species. A recent large-scale fish kill episode, and a long trend decrease in fish stocks also reflects the bay’s degraded water quality. Although pollution of Guanabara Bay is not a recent problem, the hosting of the 2016 Olympic Games propelled the government to launch a series of plans to restore the bay’s water quality. If all plans are fully implemented, the restoration of Guanabara Bay and its shores may be one of the best legacies of the Olympic Games in Rio de Janeiro. PMID:26635734

    The article that one presents has for purpose outline and comment on the recent modifications to the Penal Code for the Federal District of México which establish, for the first time, crimes related to the artificial procreation and to the genetic manipulation. Also one refers to the interaction of the new legal texts with the sanitary legislation of the country. Since it will be stated in some cases they present confrontations between the penal and the sanitary reglamentation and some points related to the legality or unlawfulness of a conduct that stayed without the enough development. These lacks will complicate the application of the new rules of the Penal Code of the Federal District.

    The purpose of the study was to assess the sanitary-and-hygienic state of solid garbage (SG) burial grounds in the Perm Territory in different stage of a life cycle. This paper presents the results of the study of deposited waste, forming dump soil, and SG ground emissions by general sanitary and sanitary-microbiological parameters and their effect on environmental objects. The performed studies of the sanitary-and-hygienic situation on some grounds of the Perm Territory suggest that there is a need for setting up a system for sanitary-and-monitoring of SG ground and for elaborating engineering, organizational, and prophylactic measures to assure the sanitary-and-hygienic safety of objects and to control the quality and quantity of waste to be buried and the currents of emissions (ground body degassing, filtrating sewage drainage and purification).

  17. Estimation of the collective sanitary impact of the land contamination by the radioactivity found at Gif sur Yvette

    International Nuclear Information System (INIS)

    2002-06-01

    The company 'Societe Nouvelle du Radium' extracted radium and produced radium needles in Gif-sur-Yvette (Essonne) from 1904 to 1957. In 1959, this site was converted into a habitable zone. Since then, this district called the 'Petite Coudraie' has been going through several radioactivity measurements and decontamination works. In 2000, the detection of very high levels of radon above sanitary recommendations in one house encouraged the local authorities to launch a systematic investigation and risk analysis in order to take the necessary measures against radiological risks for the whole concerned district. The 'Direction Departementale des Affaires Sanitaires et Sociales' (D.D.A.S.S.), the French Institute of Public Health (InVS) and the Institute of Nuclear Protection and Security (I.P.S.N.) conducted a health impact assessment of the pollution in this area. The Office for the Protection against Ionizing Radiations (O.P.R.I.) and the I.P.S.N. first measured the radioactivity found on the surface area. The I.P.S.N. then conducted a dosimetric study based on the measurement results and realistic exposure scenarios of adults and children present in the area. Finally, on the base of these results, the InVs did a quantitative risk assessment of cancer due to exposure to the radioactive residuals from the past industrial activities which is the subject of this report. This assessment allows to estimate the extent of this potential health impact due to the contamination of the area with the current scientific knowledge. It assesses the contribution of the various sources ways of exposure to risk and therefore directs the measures of management priority. Finally, it also allows to appreciate the relevance of an epidemiological study on the population who was present in this area. (author)

  2. Radiological Risk Assessment for King County Wastewater Treatment Division

    Energy Technology Data Exchange (ETDEWEB)

    Strom, Daniel J.

    2005-08-05

    Staff of the King County Wastewater Treatment Division (WTD) have concern about the aftermath of a radiological dispersion event (RDE) leading to the introduction of significant quantities of radioactive material into the combined sanitary and storm sewer system in King County, Washington. Radioactive material could come from the use of a radiological dispersion device (RDD). RDDs include "dirty bombs" that are not nuclear detonations but are explosives designed to spread radioactive material (National Council on Radiation Protection and Measurements (NCRP) 2001). Radioactive material also could come from deliberate introduction or dispersion of radioactive material into the environment, including waterways and water supply systems. This document develops plausible and/or likely scenarios, including the identification of likely radioactive materials and quantities of those radioactive materials to be involved. These include 60Co, 90Sr, 137Cs, 192Ir, 226Ra, plutonium, and 241Am. Two broad categories of scenarios are considered. The first category includes events that may be suspected from the outset, such as an explosion of a "dirty bomb" in downtown Seattle. The explosion would most likely be heard, but the type of explosion (e.g., sewer methane gas or RDD) may not be immediately known. Emergency first responders must be able to quickly detect the radioisotopes previously listed, assess the situation, and deploy a response to contain and mitigate (if possible) detrimental effects resulting from the incident. In such scenarios, advance notice of about an hour or two might be available before any contaminated wastewater reaches a treatment plant. The second category includes events that could go initially undetected by emergency personnel. Examples of such a scenario would be the inadvertent or surreptitious introduction of radioactive material into the sewer system. Intact rogue radioactive sources from industrial radiography devices, well-logging apparatus, or

    2008-01-01

    According to the national plan of actions on environmental protection, industrial garbage recycling is to be introduced in Almaty and Astana for the sustainable development of the Republic of Kazakhstan. Integrated assessment of the hazard of garage is made by the sanitary-and-chemical and sanitary-and-epidemiological indices to provide the hygienic and ecological reliability of a procedure for neutralization and utilization of solid garbage (SG). According to the data obtained, Astana SG Astana in summer is characterized by the high total level of bacterial contamination. The indices of microbial contamination of SG and soil near the dustbins correlate with the density of population and the maturity of an infrastructure. Comparison of the sanitary-and-epidemiological indices of different types of SG (wastes from housing facilities, wholesale and retail outlays, and education, culture, and entertainment institutions) revealed no significant differences. According to the sanitary-and-helmintological indices, the Astana soil should be classified as pure (noninvasive). Involvement of SG into industrial recycling should be accompanied by a hygienic assessment of the hazard of waste and the reliability of used technologies in the context of warning and on-going sanitary surveillance.

This environmental analysis will primarily focus on improvements to the SRWTP facilities and a 24 inch pipeline designed to carry up to 5,400 gallons per minute of secondarily treated wastewater. The wastewater will be transported from the Lake County Sanitation District's Southeast Regional Wastewater Treatment Plant, Middletown Wastewater Treatment Plant with additional make-up water from Clear Lake to the Southeast portion of the Geysers Geothermal Field in Lake and Sonoma Counties, California

  10. Solidarity: an innovative perspective in the management and organization of Sanitary Surveillance actions.

    Science.gov (United States)

    Leal, Cristian Oliveira Benevides Sanches; Teixeira, Carmen Fontes de Souza

    2017-10-01

    This is a theoretical essay about the development of the concept of solidarity, a word used in the regulatory framework and in political proposals to reorient the Brazilian Unified Health System (SUS). The methodology consisted of mapping authors addressing human action aspects related to this theme from Durkheim's tradition, linking them to his followers, like Marcel Mauss and authors from the "anti-utilitarianism" movement in social sciences. Solidarity is one way to express a "gift" and appears as a multidimensional action, where duty and freedom, instrumental interest and disinterest interpose and interlace. The planning and execution of sanitary surveillance (VISA) actions requires comprehension of organizational forms and solidary relationship management among agents involved in health risk control, transcending the strongly normative aspect of the prevailing supervision actions. The development of associative actions involving sanitary surveillance professionals, economic agents and consumers, aiming to share the responsibilities in the health risk control of products, services and environments subjected to Sanitary Surveillance action is suggested.

    At the beginning of the First World War the most typical diseases in the Russian Army were typhoid, typhus, diphtheria, cholera, smallpox and other infectious diseases. At the beginning of the First World War the level of infectious morbidity was significantly low, but further increased and pandemic risk arose. Servicemen were mostly ill with typhus, relapsing fever, flux, cholera, smallpox and typhoid. The highest mortality rate was registered in patients with cholera, typhus and typhoid. According the prewar deployment program of the Russian Army anti-epidemiologic facilities were established. By the end of war were established 110 sanitary-and-hygienic and 90 disinfection units. However, organization of anti-epidemiologic security was unsatisfactory. Due to lack of specialists and equipment anti-epidemiologic facilities of units were under strength. Commanders of sanitary units and sanitary service had not enough resources for operational service in the Forces and facilities of rear area.

    This paper aims to evaluate the hygienic-sanitary conditions of kitchens in philanthropic and public daycare centers in the city of São Paulo using a tool of easy application. Information on the hygienic-sanitary conditions was gathered observing the operational conditions of five public and philanthropic daycare centers in the city of São Paulo. A score was developed for classifying the risks of food contamination. The operational conditions in the kitchens of the studied philanthropic and public daycare centers in the city of São Paulo can result in contamination of the prepared food. Among the most important risk factors for food contamination is the behavior of the workers who handle the food. Training and continuous supervision of the involved personnel are the best and easiest alternatives for assuring the appropriate hygienic-sanitary conditions and quality of the food offered to the children in these daycare centers.

    Advanced treatments are attributed to improving the quality of various types of waste such as the sanitary wastewater. The heterogeneous photocatalysis is an alternative that allows to improve the effluents conditions. This is possible because many chemical compounds of environmental concern can be degraded using UV radiation on a semiconductor. However, to enable the efficiency of the process photocatalytic is necessary to conduct a study of optimization to establish favorable conditions between selected variables. The aim of this work was a reactor solar photocatalytic optimization using factorial design 2{sup k}, depending on variables: mass (TiO{sub 2}), time (min) and flow of air (L min{sup -1}), using as analytical response the removal of color. The experiment was conducted at the Faculty of Agricultural Engineering (FEAGRI) and it was used the sanitary wastewater of there. The results indicated that there were significant efficiency using combinations mass = 1000 mg L{sup -1}, time = 360 min and flow of air = 5 L min{sup -1}. In the calculations of factorial design, the time showed a marked positive effect of 7.76, while the flow of air, when in excess, had an inhibitor behavior, even getting positive effect. (author)

    Full Text Available The use of treated wastewater for agricultural purposes can be an alternative to maintaining the quality of water bodies and the biota of natural systems. It can also reduce the demand for water and preserve water supplies for more important uses. This study aimed to evaluate the effects of wastewater reuse in the microbiological quality of above ground parts of sunflower crops. The experiment was conducted from July to September 2012 in the greenhouse of the Department of Agricultural Engineering (DEA at the Federal University of Sergipe, São Cristóvão Campus. Treated wastewater was collected at the Sewage Treatment Plant (WWTP Rosa Elze, located in the municipality of São Cristóvão, SE. Irrigation was performed using different ratios of water and treated wastewater. The irrigation followed the FAO 56 method. We used a completely randomized design (CRD with five treatments and four replicates per plot. The data were analyzed according to the parameters recommended by Resolution no. 12, 02/01/2001 of the Brazilian National Agency for Sanitary Vigilance. Coliforms, E. coli, yeast and mold, and Salmonella were counted. Results have shown that the microbiological quality of the superficial area of sunflower crops analyzed met the standards of Brazilian law. However, further studies should be conducted to investigate the effects of soil.

    Full Text Available In this study, the performance of a pilot-scale vermifilter (VF for the treatment of hospital wastewater using the earthworm species Eisenia fetida was evaluated. The earthworms’ gut acts as a bioreactor and can ingest the wastewater solid and liquid organic wastes and expel these as vermicompost. A pilot-scale vermifilter was installed and operated for 133 days in one of hospitals in Hamadan city; the designed system was fed with the influent passed through coarse and fine grillage and the sedimentation tank of the hospital’s sanitary collection system. In order to study the efficiency of the system, the variations of pH value, chemical oxygen demand (COD, biochemical oxygen demand (BOD5, and total suspended solids (TSS were measured. In addition, a conventional geofilter (GF without Earthworm was used as the experimental control. The vermifiltration caused a significant decrease in the levels of COD (75%, BOD5 (93%, and TSS (89% as well as neutralized pH in the wastewater. Also, these contents in the geofilter were observed to be 65%, 71%, and 71%, respectively. The vermifiltration technology can, therefore, be applied as an environmentally friendly method for hospital wastewater treatment.

    The purpose of the study was to characterize natural ventilation in full-scale gravity collection system components while measuring other parameters related to ventilation. Experiments were completed at four different locations in the wastewater collection systems of Los Angeles County Sanitation Districts, Los Angeles, California, and the King County Wastewater Treatment District, Seattle, Washington. The subject components were concrete gravity pipes ranging in diameter from 0.8 to 2.4 m (33 to 96 in.). Air velocity was measured in each pipe using a carbon-monoxide pulse tracer method. Air velocity was measured entering or exiting the components at vents using a standpipe and hotwire anemometer arrangement. Ambient wind speed, temperature, and relative humidity; headspace temperature and relative humidity; and wastewater flow and temperature were measured. The field experiments resulted in a large database of measured ventilation and related parameters characterizing ventilation in full-scale gravity sewers. Measured ventilation rates ranged from 23 to 840 L/s. The experimental data was used to evaluate existing ventilation models. Three models that were based upon empirical extrapolation, computational fluid dynamics, and thermodynamics, respectively, were evaluated based on predictive accuracy compared to the measured data. Strengths and weaknesses in each model were found and these observations were used to propose a concept for an improved ventilation model.

    Modern wastewater treatment plants are often inappropriate for communities in developing countries. Such communities lack the funding, resources and skilled labour required to implement, operate, and maintain these plants. This research was conducted to investigate and establish an appropriate wastewater treatment system for the district of Gunung Kidul, Indonesia. Due to its lack of water during the dry season, this district is considered one of the poorest areas in the nation. First, wastewater was stored in septic tank units for a retention time of 26 days. Anaerobic conditions occurred, resulting in an 80% reduction of initial COD. The retained sludge was well stabilized with great potential, if dewatered, for reuse as fertilizer. Consequently, supernatant was separated for experiments consisting of lab scale aerobic sand filtering unit. Through filtration, further removals of COD (about 30%) and pathogens were achieved. Rich in nitrogen, the resulting effluent could be used for irrigation and soil conditioning. With faecal sludge and also a mixture of septic sludge and food waste, the hydrolysis stage of anaerobic digestion was examined. This paper discusses the laboratory findings in Karlsruhe and the design and implementation of a treatment system in Glompong, Indonesia.

    Carstensen, Niels Jacob

    The introduction of on-line sensors for monitoring of nutrient salts concentrations on wastewater treatment plants with nutrient removal, opens a wide new area of modelling wastewater processes. The subject of this thesis is the formulation of operational dynamic models based on time series...... of ammonia, nitrate, and phosphate concentrations, which are measured in the aeration tanks of the biological nutrient removal system. The alternatign operation modes of the BIO-DENITRO and BIO-DENIPHO processes are of particular interest. Time series models of the hydraulic and biological processes are very......-known theory of the processes with the significant effects found in data. These models are called grey box models, and they contain rate expressions for the processes of influent load of nutrients, transport of nutrients between the aeration tanks, hydrolysis and growth of biomass, nitrification...

    1987-01-01

    The Feed Materials Production Center (FMPC), a US Department of Energy facility at Fernald, Ohio, is constructing a fluidized-bed biodenitrification plant based on pilot work conducted at the Oak Ridge National Laboratory (ORNL) in the late 1970s and early 1980s. This plant is designed to treat approximately 600 to 800 L/min of wastewater having a nitrate concentration as high as 10 g/L. The effluent is to contain less than 0.1 g/L of nitrate. Since this new facility is an extrapolation of the ORNL work to significantly larger scale equipment and to actual rather than synthetic wastewater, design verification studies have been performed to reduce uncertainties in the scaleup. The results of these studies are summarized in this report. 7 refs., 1 fig

    The Mediterranean basin (and particularly North African countries) is one of the poorest regions in the world in terms of water resources. In Tunisia, treated municipal wastewater is becoming one of the main alternative sources of water. Indeed, in 2007, 99 municipal wastewater treatment plants (WWTP) has treated a quantity of 215 millions of m 3 from which more than 30 pour cent are reused. The treated volume in 2011 is expected to be 266 millions m 3 , whereas the reused wastewaters should reach more than 50 pour cent. However, especially in the eastern and northern Mediterranean regions, wastewaters are inefficiently treated and re-used for irrigation or sanitary purposes, serving as a carrier for diseases or causing water pollution when discharged to water bodies. In the last decade, several water treatment technologies have been used in the region with little success in pathogen removal. Membrane bioreactor (MBR) technology is a very promising alternative to those conventional water treatments as membranes act as a barrier against bacteria and viruses achieving a high degree of water purification. However, most membrane bioreactors currently in use have very high running costs because of the high pressure drop and high air-flushing rate required for their operation. The objective of this PURATREAT FP 6 EU project was to study a new approach to the operation of membrane bioreactors. This study was included a comparison of three leading membrane technologies. The operating procedure to be studied is expected to yield very low energy consumption and reduced maintenance costs. After the start up period, the MBR3 was operated with a MLSS concentration of 4.5 and 9 g/L, respectively. Different fluxes as 16, 18, 20 and 22 Lh -1 m -2 were tested. When the flux increase from 16 to 22 Lh -1 m -2 , the treatment energy consumption decreased from 7 to 5 kWh/m 3 . However the increases of MLSS concentration from 4.5 and 9 g/L raise the membrane fouling frequency from 1

    This test report documents the results obtained while conducting operational testing of the sampling equipment in the 225-WC building, the PFP Wastewater Sampling Facility. The Wastewater Sampling Facility houses equipment to sample and monitor the PFP's liquid effluents before discharging the stream to the 200 Area Treated Effluent Disposal Facility (TEDF). The majority of the streams are not radioactive and discharges from the PFP Heating, Ventilation, and Air Conditioning (HVAC). The streams that might be contaminated are processed through the Low Level Waste Treatment Facility (LLWTF) before discharging to TEDF. The sampling equipment consists of two flow-proportional composite samplers, an ultrasonic flowmeter, pH and conductivity monitors, chart recorder, and associated relays and current isolators to interconnect the equipment to allow proper operation. Data signals from the monitors are received in the 234-5Z Shift Office which contains a chart recorder and alarm annunciator panel. The data signals are also duplicated and sent to the TEDF control room through the Local Control Unit (LCU). Performing the OTP has verified the operability of the PFP wastewater sampling system. This Operability Test Report documents the acceptance of the sampling system for use

    2000-01-01

    The internal organisation for first aid to the injured in case of an accident on E.D.F. nuclear power plant calls for the immediate assistance of a first aid team, consisting of five workers, under the direction of a principal first aid officer; one of the first aid workers, the sanitary officer who instructs the first aid workers intervention awaiting the arrival of an external medical. When the 'Sanitary on-site Emergency Plan' was up' dated, twenty medical doctors and seventy members of staff from five different sites were questioned as to the function of the sanitary officer. The conclusions revealed a notable difference of training amongst the different sites, and concerning first aid organisation, difference of priority of actions, extent of their participation once the medical team arrives and their participation in case of decontamination treatment. The medical doctors and staff lay a particular stress on importance of defining on a national scale the limits of role and responsibilities of the sanitary officer and establish a more specific training in this field, consequently motivating commitment and professionalism involvement. There is a great difference between the training and coaching of the first aid assistance and fire protection teams. To conclude, we propose that the first aid officer be known as first aid coordinator and the qualification of 'Certificat de Formation aux Premiers Secours en Equipe' in compliance with the current legislation together with a specific nuclear module and they should undergo regular on-site drills.

    Full Text Available It was found out that in most cases the system of removable water disposal is arranged with violations, i.e. cesspools that collect runoffs are either not designed at all — waste water merge into an open trench (ditch, and then water is filtered into the ground, or are designed against the rules (instead of a cesspool the user presupposes a simple hole dug in the ground. The authors witnessed the cases of ingress of wastewater into open waters, near which holiday villages are situated. This fact raises the question on the necessity of solving these problems which will prevent pollution of soil and surface waters, as well as the surrounding areas by sewages to prevent the development of infections and to prevent environmental disaster on a local scale. If you have a small rate of water flow in a summer cottage, it is feasible to design a sump for removal of faecal discharge (human physiological discharge, which are the most dangerous. It is advisable to install in the ground sealed (cumulative capacity, and build headroom on the top in the form of a toilet cabin (detached structure. This will allow completely getting rid of contamination with sewage effluents. The volume of the tank must be calculated individually depending on the water consumption on the site. Periodically it is needed to call out a cesspoolage truck after filling the reservoir, which would be then emptied of faecal material. In the last 20 years in our country a promising trend in removable sanitation began to develop — bio toilets. They became popular in country houses, as well as for persons with disabilities A composting toilet is a portable container, which is very compact and can be installed in any location of a country house. A more costly option, but an environmentally sound and convenient one to use is the construction of local water disposal systems with the use of not only mechanical, but also biological treatment. The choice of a particular scheme of

    2015-10-01

    Full Text Available Wastewater collection network simulation in normal conditions dose not provide performance assessment in unusual circumstances. In this paper, a model has been developed for risk assessment of wastewater collection systems to manage their performance under natural or man-made critical conditions. In this model, certain criteria were defined, fuzzy MADM techniques were exploited, and a questionnaire was employed to measure such risk parameters as the probability of threats, the severity of their impacts, and the vulnerability of the network components. Based on the calculated magnitude of the risks, the threats and hazards were classified into groups ranging from low-risk to high-risk threats. The approaches adopted to combat the risks were also classified into the following three categories: "to deal with the risk", "risk shifting", and "risk taking". This process was implemented for the wastewater collection system in Shahrak-Gharb District in Tehran as a case study. ‘Introduction of chemical pollutants into the sewers’ and ‘drastic changes in wastewater quality’ were identified as the most threatening crises for the district and the ‘risk reduction strategy’ was proposed for combating the critical conditions in this district.

    2002-01-01

    'Full text:' This presentation will describe the nature, scope, and findings of a third-party evaluation of a wastewater treatment technology identified as the Advanced Wastewater Treatment System Inc.'s Superior Extended Aerobic Digester System (SEADS). SEADS is an advanced miniaturized wastewater treatment plant that can meet advanced wastewater treatment standards for effluent public reuse. SEADS goes beyond primary and secondary treatment operations to reduce nutrients such as nitrogen and phosphorus, which are typically found in excessive quantities in traditional wastewater treatment effluent. The objective of this evaluation will be to verify the performance and reliability of the SEADS to treat wastewater from a variety of sources, including domestic wastewater and commercial industrial wastewater. SEADS utilizes remote telemetry equipment to achieve added reliability and reduces monitoring costs as compared to many package wastewater treatment plants. The evaluation process will be overseen and coordinated by the Environmental Technology Evaluation Center (EvTEC), a program of the Civil Engineering Research Foundation (CERF), the research and technology transfer arm of the American Society of Civil Engineers (ASCE). EvTEC is a pilot program evaluating innovative environmental technologies under the US Environmental Protection Agency's (USEPA) Environmental Technology Verification (ETV) Program. Among other performance issues, the SEADS technology evaluation will address its ability to treat low flows-from remote individual and clustered housing applications, and individual commercial applications in lieu of a main station conventional wastewater treatment plant. The unneeded reliance on particular soil types for percolation and the improved effluent water quality over septic systems alone look to make these types of package treatment plants a viable option for rural communities, small farms, and other low-flow remote settings. Added benefits to be examined

    Urban effluents are rich in nutrients, organic matter, pharmaceuticals and personal care products (PPCPs), pesticides, hydrocarbons, surfactants, and others. Previous studies have shown that oysters Crassostrea gigas accumulate significant levels of linear alkylbenzenes (LABs) in sanitary sewage contaminated sites, but there is little information about its toxicological effects in marine bivalves. The aim of this study was to analyze the transcription of genes in two tissues of C. gigas exposed for 12, 24, and 36 h to LABs or sanitary sewage. Likewise, the activity of antioxidant and biotransformation enzymes was measured in oysters exposed for 36 h in all groups. Oysters exposed to LABs and oysters exposed to sanitary sewage showed different patterns of transcriptional responses. LAB-exposed oysters showed lower level of biological responses than the oysters exposed to sanitary sewage. Despite the ability of the oyster C. gigas to accumulate LABs (28-fold), the data indicate that these contaminants are not the cause for the transcriptional responses observed in oysters exposed to sanitary sewage. Possibly, the biological changes observed in the sanitary sewage-exposed oysters are associated with the presence of other contaminants, which might have caused synergistic, additive, or antagonistic effects. The results show that FABP-like and GST-ω-like messenger RNAs (mRNAs) have a rapid response in tissues of oyster C. gigas exposed to sanitary sewage, suggesting a possible protective response and a role in maintaining homeostasis of these organisms.

E-mail: keniacarrijo@ famev.ufu.br To compare the concordance of the diagnosis of porcine enzootic pneumonia (PEP by post-mortem Sanitary Inspection with other methods (histophatology and immunohistochemistry - IHC, were used lung tissue samples from 100 pigs slaughtered under sanitary inspection, and 50 of these had macroscopic lesions suggestive of PEP and 50 had no such lesions. These were fixed in 10% buffered formalin and processed by routine procedures for paraffin embedding and IHC technique for Mycoplasma hyopneumoniae using a monoespecific polyclonal antibody. The study demonstrating that there is concordance between the diagnosis of Sanitary Inspection with histophatology, between the diagnosis of Sanitary Inspection with IHC and histophatology with IHC. It can be conclude that when the lung has gross lesions of PEP, the probability the result is positive to M. hyopneumoniae by IHC and the presence of microscopic lesions increases. Thus, the microscopic diagnosis for PEP is feasible because it is associated to the other, so that the diagnosis given by the officials of Sanitary Inspection in slaughterhouses is not wrong; the macroscopic diagnosis is therefore a valid method for the diagnosis of PEP, it being understood this is not to say that the detection of M. hyopneumoniae.

    The emergence of resistance to last resort antibiotics is a public health concern of global scale. Besides direct person-to-person propagation, environmental pathways might contribute to the dissemination of antibiotic-resistant bacteria and antibiotic resistance genes (ARGs). Here, we describe the incidence of blaNDM-1, a gene conferring resistance to carbapenems, in the wastewater of Jeddah city over a one-year period. blaNDM-1 was detected at concentrations ranging from 104 to 105 copies per m3 of untreated wastewater during the entire monitoring period. These results indicate the ubiquity and high incidence of blaNDM-1 in the local wastewater. To track the bacteria carrying blaNDM-1, we isolated Escherichia coli PI7, a strain of the sequence type ST101, from wastewater around the Hajj event in October 2013. Genome sequencing of this strain revealed an extensive repertoire of ARGs as well as virulence and invasive traits. These traits were further confirmed by antibiotic resistance profiling and in-vitro cell internalization in HeLa cell cultures. Given that this strain remains viable even after a certain duration in the sewerage, and that Jeddah lacks a robust sanitary infrastructure to fully capture all generated sewage, the presence of this bacterium in the untreated wastewater would represent a potential hazard to the local public health. To the best of our knowledge, this is the first report of a blaNDM-1-positive E. coli isolated from a non-nosocomial environment in Saudi Arabia, and may set a preceding concern for the need to establish an improved surveillance for carbapenem-resistant E. coli in the country and nearby regions.

It supplies nearly 2 million square feet of heating and cooling for Windsor's city centre. The district energy system produces hot water or chilled water at a central plant. Energy is then piped out to buildings in the area, including the Art Gallery of Windsor, the Royal Bank Business Centre, the Windsor Justice Facility, the Windsor Casino, and Northwind Windsor. The energy, which is transferred through heat exchangers, is used for space heating, domestic hot water heating, and air conditioning. The 8 reasons for getting connected are: (1) less management costs, (2) lower energy costs, (3) lower level of risk management, (4) stable energy rates, (5) better use of building space, (6) reliable service, (7) reduced expansion costs, and (8) a cleaner environment. District heating improves air quality through reduced carbon dioxide and nitrogen oxide emissions. In addition, fuel delivery and storage are eliminated. figs.

    Full Text Available This work on the process of biosorption of nickel and chromium in an ascendant continuous-flow, fixed packed-bed bioreactor of sanitary sewage sludge was conducted in a search for solutions to the environmental problem caused by heavy metals. Analysis of the results demonstrated that the absorbent had an extraordinary capacity for biosorption of the heavy metals studied at about 9.0 pH of the effluent, with a removal percentage of over 90.0% for the two metals. Chemometric study results demonstrated that 20 days of the experimental system function were sufficient for achieving the maximum efficiency of sorption of the heavy metals studied by the sanitary sewage sludge employed.

    1995-02-01

    Eighty-nine wells of the LFW series monitor groundwater quality in the Steed Pond Aquifer (Water Table) beneath the Sanitary Landfill at the Savannah River Site (SRS). These wells are sampled quarterly to comply with the South Carolina Department of Health and Environmental Control Domestic Waste Permit DWP-087A and as part of the SRS Groundwater Monitoring Program. Dichloromethane, a common laboratory contaminant, and trichloroethylene were the most widespread constituents exceeding standards during 1994. Benzene, chloroethene (vinyl chloride), 1,2-dichloroethane, 1,1-dichloroethylene, 1,2-dichloropropane, gross alpha, mercury, nonvolatile beta, tetrachloroethylene, and tritium also exceeded standards in one or more wells. The groundwater flow direction in the Steed Pond Aquifer (Water Table) beneath the Sanitary Landfill was to the southeast (universal transverse Mercator coordinates). The flow rate in this unit was approximately 140 ft/year during first and fourth quarters 1994

    A series of the investigations of the electron beam influence on sanitary-model test cultures and antibiotics in model solutions has been carried out. For each of the test objects, the authors have found the boundary doses of the absorbed radiation. The higher doses cause the sharp increase in the bactericidal influence, which becomes complete. The sanitary-bactericidal indices of the water samples remain sable during 6 days. The samples of antibiotics in various concentrations (from 100 UA) have been irradiated. It is proved that the substratum processing by the beam (in the regimes 30 kGy) causes diminution and complete neutralization of the antibacterial activity in all probes of the samples

    This article analyzes the international sanitary conferences that were held in South America in 1873 and 1887, involving the Brazilian Empire and the Republics of Argentina and Uruguay, as an integral part of a series of similar events that took place in Europe and North America starting in the second half of the nineteenth century. The interests of the countries involved, namely trade relations and immigration from Europe - both directly affected by the epidemics - are discussed, and the repercussions of these sanitary agreements on the other countries in the Americas are indicated. The American health conventions in the late nineteenth century represented the first initiatives in the Americas to solve international public health problems.

  15. Cleaner mites: sanitary mutualism in the miniature ecosystem of neotropical bee nests.

    2009-06-01

    Cleaning symbioses represent classic models of mutualism, and some bee mites are thought to perform cleaning services for their hosts in exchange for suitable environments for reproduction and dispersal. These mutual benefits, however, have not been rigorously demonstrated. We tested the sanitary role of bee mites by correlating mite loads with fungal contamination in natural nests of Megalopta genalis and Megalopta ecuadoria and by experimentally manipulating mite loads in artificial cells with developing brood. Field observations revealed significant correlations between the presence of mites and the absence of fungi inside the brood cells, as well as between the absence of mites and increased bee mortality. Likewise, experimental brood cells with mites have fewer fungal colonies than do cells without mites. Field observations and experimental manipulations, therefore, provide clear evidence of the sanitary effect of mites in nests of Megalopta bees. This bee-mite association constitutes one of the few examples of terrestrial cleaning mutualisms.

  16. Sanitary quality of surface water during base-flow conditions in the Municipality of Caguas, Puerto Rico, 2014–15: A comparison with results from a similar 1997–99 study

    Rodríguez-Martínez, Jesús; Guzmán-Ríos, Senén

    2017-06-26

    A study was conducted in 2014–15 by the U.S. Geological Survey (USGS), in cooperation with the Municipality of Caguas, to determine if changes in the stream sanitary quality during base-flow conditions have occurred since 1997–99, when a similar study was completed by the USGS. Water samples were collected for the current study during two synoptic surveys in 2014 and 2015. Water samples were analyzed for fecal and total coliform bacteria, nitrate plus nitrite as nitrogen, nitrogen and oxygen isotopes of nitrate, and human health and pharmaceutical products. Water sampling occurred at 39 stream locations used during the 1997–99 study by the USGS and at 11 additional sites. A total of 151 stream miles were classified on the basis of fecal and total coliform bacteria results.The overall spatial pattern of the sanitary quality of surface water during 2014–15 is similar to the pattern observed in 1997–99 in relation to the standards adopted by the Puerto Rico Environmental Quality Board in 1990. Surface water at most of the water-sampling sites exceeded the current standard for fecal coliform of 200 colonies per 100 milliliters adopted by the Puerto Rico Environmental Quality Board in 2010. The poorest sanitary quality was within the urban area of the Municipality of Caguas, particularly in urban stream reaches of Río Caguitas and in rural and suburban reaches bordered by houses in high density that either have inadequate septic tanks or discharge domestic wastewater directly into the stream channels. The best sanitary quality occurred in areas having little or no human development, such as in the wards of San Salvador and Beatriz to the south and southwest of Caguas, respectively. The concentration of nitrate plus nitrite as nitrogen ranged from 0.02 to 9.0 milligrams per liter, and did not exceed the U.S. Environmental Protection Agency drinking-water standard for nitrate as nitrogen of 10 milligrams per liter. The composition of nitrogen and oxygen

  17. District heating in Flensburg

    Energy Technology Data Exchange (ETDEWEB)

    Prinz, W.

    1981-01-01

    The majority of our population, but also of our authorities, are still skeptical or even disapproving towards district heating. The reasons of this negative attitude are partly psychological - e.g. the individualism of the Swiss and their dislike for too centralised structures and ''forced connections'' - but also the existence of finished gas supply networks and the fear of considerable pre-investments and torn streets over years. The following article - held as a speech on the information meeting ''District heating and the possible contribution of nuclear energy'' organised by the Swiss Association for Atomic Energy in Bern shows a practical problem solving at the example of the district heating in Flensburg and deals with these questions.

    1981-01-01

    Changing the quality of circulating water, raising the effectiveness of sedimentation, examples of biological treatment of wastewater are presented. The necessity of continuing the studies on biological treatment of wastewater is demonstrated. It is considered useful to define the importance of KhPK and BP5 in each case. During biological treatment in ponds, to define the relation BPK5:N:P, research on conditions for nutrient removal must be done. To do this, as well as decrease the significance of KhPK, a mathematical model for defining the effectiveness of biological treatment of wastewater and consequently their reuse must be developed.

    The Oak Ridge Y-12 Plant is situated adjacent to the Oak Ridge city limits and is operated by the United States Department of Energy (DOE). The Y-12 Plant is located on 4,860 acres, which is collectively referred to as the Y-12 Plant site. Among the missions for which the facility is in existence are producing nuclear weapons components, supporting weapon design laboratories, and processing special nuclear materials (SNM). The Y-12 Plant is under the regulatory guidance of DOE Order 5400.5 and has complied with the technical requirements governing SNM since its issue. However, an in-depth review with appropriate documentation had not been performed, prior to the effect presented herein, to substantiate this claim. As a result of the solid waste issue, it was determined that other types of waste should be formally reviewed for content with respect to SNM. Therefore, a project was formed to investigate the conveyance of SNM through the sanitary sewer system. It is emphasized that this project addresses only effluent from the sanitary sewer system and not the storm sewer system. The project reviewed sanitary sewer data both for the Y-12 Plant and the Y-12 Plant site

    This study evaluated the efficiency of a shallow (0.5 m deep) waste stabilization pond series to remove high concentrations of ammonia from sanitary landfill leachate. The pond system was located at EXTRABES, Campina Grande, Paraiba, Northeast Brazil. The pond series was fed with sanitary landfill leachate transported by road tanker to the experimental site from the sanitary landfill of the City of Joao Pessoa, Paraiba. The ammoniacal-N surface loading on the first pond of the series was equivalent to 364 kg ha(-1) d(-1) and the COD surface loading equivalent to 3,690 kg ha(-1) d(-1). The maximum mean ammonia removal efficiency was 99.5% achieved by the third pond in the series which had an effluent concentration of 5.3 mg L(-1) ammoniacal-N for an accumulative HRT of 39.5 days. The removal process was mainly attributed to ammonia volatilization (stripping) from the pond surfaces as a result of high surface pH values and water temperatures of 22-26°C. Shallow pond systems would appear to be a promising technology for stripping ammonia from landfill leachate under tropical conditions.

    2010-11-01

    The term sanitary safety (SS) appeared in the international debate mainly due to the emerging sanitary crisis, although its meaning has remained obscure. This paper aims to analyze the concept of SS brought into the Brazilian sanitary surveillance upon the creation of the National Health Surveillance Agency. An exploratory case study was undertaken with technical data analysis and semi-structured interviews with informants who had taken part in the process of formulating the body's institutional design. The following categories were analyzed: incorporation of the SS term into the institutional mission, the SS concept and SS mechanisms. The SS concept was analyzed in both institutional and technical discursive dimensions. The former elicits the sense of strategy, a reliable relationship and legitimacy whereas the latter shows the sense of an acceptable risk-benefit relationship from the perspective of individual and collective health protection and promotion. The SS concept was found to encompass health-related products, technologies and services, especially those designed for medical diagnosis and treatment, but environmental issues received little mention. The scope of the SS concept was shown to be widening to include the surveillance of hospital infection, drugs and blood.

    The consumption of street food is an economical and practical alternative for the population. However, concerns regarding the safety of these foods are increasing. Thus, this study aimed to analyze the hygienic and sanitary conditions of the street food trade in Uberaba in the State of Minas Gerais. For this purpose, 30 street vending sites were evaluated using a structured questionnaire and microbiological analysis of food handlers' hands and food contact recipients and surfaces. The findings showed low adequacy of street food regarding hand hygiene and food contact surfaces. With respect to surfaces, the results for mesophilic aerobic microorganisms revealed that only 23.3% had satisfactory sanitary conditions. The level of contamination of hands by fecal thermotolerant coliforms and/or Coagulase positive Staphylococci was unsatisfactory in approximately 47% of food handlers. The conclusion drawn is that the hygienic and sanitary conditions of food handlers in Uberaba are poor. It is therefore necessary to adopt effective and permanent training programs on food safety for food handlers urgently.

  17. Diptera of sanitary importance associated with composting of biosolids in Argentina

    Directory of Open Access Journals (Sweden)

    Valeria Alejandra Labud

    2003-12-01

    Full Text Available OBJECTIVE: Odorous compounds produced at the biosolids composting plant in Bariloche (NW Patagonia attract a variety of insects, mainly belonging to the order Diptera. In order to characterize these flies, collected specimens were taxonomically identified, their community characteristics were described and their sanitary and synanthropic importance and autochthonous or introduced character were determined. METHODS: Sampling was performed from October 1999 until March 2000. Adults were collected using an entomological net, and larvae and puparia were obtained from the composting material and incubated to obtain adults. Richness, abundance and sex ratio were calculated. RESULTS: A total of 9 taxa of Diptera were identified: Sarconesia chlorogaster, Phaenicia sericata, Calliphora vicina, Cochliomya macellaria, Ophyra sp, Muscina stabulans, Musca domestica, Sarcophaga sp and Fannia sp. Specimens of Anthomyiidae, Acaliptratae and one larva of Eristalis tenax were also found. Ophyra sp. was the most abundant taxa. All the captured Diptera belonged to introduced taxa. Most of them are considered to be eusynanthropic and/or hemisynanthropic and have sanitary importance as they may cause myiasis and pseudomyiasis. The high number of females registered and the finding of immature stages indicated that flies can develop their complete life cycle on biosolid composting windrows. CONCLUSIONS: The characterization of flies obtained in this study may be useful for defining locations of urban or semi-urban composting facilities. It also highlights the importance of sanitary precautions at such plants.

    The Miyun Reservoir provides most of Beijing's drinking water. Despite its importance, the Miyun reservoir suffers from decreasing water quality caused by uncontrolled wastewater discharges, inadequate land use and over fertilization, which increase the pressure on soil and water resources. The major pollutants are nitrogen and phosphorus which emanate to some extent from untreated sewage. So far there is little data about the existing wastewater quantity and quality in rural settlements in northern China. This study was conducted in typical villages situated along upstream rivers in the catchment of the Miyun Reservoir. The main objective was to determine the current situation and efficiency of the wastewater treatment system in rural settlements.

    Sanitary landfill leachate is one of the major problems arising from disposal of urban waste. Sanitary landfill leachate may, however, have use in agriculture. This study, therefore, aimed to analyze initial plant growth and gas exchange in sunflower seedlings supplemented with sanitary landfill leachate and subjected to drought stress through variables of root fresh mass (RFM), shoot fresh mass (SFM), total fresh mass (TFM), relative chlorophyll content (CL), stomatal conductance (g s ), transpiration rate (E), net photosynthetic rate (A), ratio of internal to external CO 2 concentration (Ci/Ca),water use efficiency (EUA), instantaneous carboxylation efficiency (A/Ci), and electron transport rate (ETR). The experimental design was a completely randomized 2 (irrigated and non-irrigated) × 4 (sand, sand + 100 kg N ha -1 organic fertilizer, sand + 100 kg N ha -1 sanitary landfill leachate, and sand + 150 kg N ha -1 sanitary landfill leachate) factorial with five replicates. Under drought stress conditions, leachate treatment supplemented with 100 kg N ha -1 exhibited higher plant fresh weights than those of the treatment containing 150 kg N ha -1 . Increases in fresh mass in plant treatments supplemented with 100 and 150 kg N ha -1 sanitary landfill leachate were related to higher photosynthetic rates.

    Nanotechnology has widespread application in agricultural, environmental and industrial sectors ranging from fabrication of molecular assemblies to microbial array chips. Despite the booming application of nanotechnology, there have been serious implications which are coming into light in the recent years within different environmental compartments, namely air, water and soil and its likely impact on the human health. Health and environmental effects of common metals and materials are well-known, however, when the metals and materials take the form of nanoparticles - consequential hazards based on shape and size are yet to be explored. The nanoparticles released from different nanomaterials used in our household and industrial commodities find their way through waste disposal routes into the wastewater treatment facilities and end up in wastewater sludge. Further escape of these nanoparticles into the effluent will contaminate the aquatic and soil environment. Hence, an understanding of the presence, behavior and impact of these nanoparticles in wastewater and wastewater sludge is necessary and timely. Despite the lack of sufficient literature, the present review attempts to link various compartmentalization aspects of the nanoparticles, their physical properties and toxicity in wastewater and wastewater sludge through simile drawn from other environmental streams.

    2001-07-01

    The concept of district energy was introduced in the City of North Vancouver, a city of 45,000, in 1997. A preliminary study was completed in 1997, followed by a tour of some district energy facilities in Finland in the same year. In 1999 a large district energy study was completed by a consultant. The study indicated the need for an investment of $15 million to implement district heating in the City. Lack of sufficient financial resources and immediately connectable heat load, the project was considered a non-starter. Some of the other factors leading to shelving the project included no current significant pricing advantages over competing energy sources and no current opportunity for cogeneration, given the low price that BC Hydro is willing to pay for independently produced power. The project, although shelved for the moment, has not been discarded. Planning and exploration are continuing, aided by the City's commitment to energy efficiency and conservation, its long term planning horizon and its significant influence over the development of some prime real estate.

    Enteric parasites are the most common cause of parasitic diseases and cause significant morbidity and mortality, particularly in developing countries like Nepal. The objective of this study was to estimate the prevalence and risk factors of intestinal parasitic infections among school going children of Lalitpur district of Nepal. A total of 1392 stool samples were collected from school children of two government, two private and two community schools of the same district. The stool samples were examined for evidence of parasitic infections by direct microscopy and confirmed by concentration methods (formal ether sedimentation technique or floatation technique by using Sheather's sugar solution). Modified Ziehl-Neelsen (ZN) staining was performed for the detection of coccidian parasites. Prevalence of intestinal parasitosis was found to be 16.7%. The highest prevalence rate was seen with Giardia lamblia (7.4%) followed by Entamoeba histolytica (3.4%) and Cyclospora cayetanensis (1.6%). Children aged 11-15 years and the ones belonging to family of agriculture workers were most commonly affected. Hand washing practice and type of drinking water also showed significant difference. The burden of parasitic infections among the school children, coupled with the poor sanitary conditions in the schools, should be regarded as an issue of public health priority and demands for effective school health programs involving periodic health education and screening.

  12. Development of an irradiation device for electron beam wastewater treatment

    International Nuclear Information System (INIS)

    Rela, Paulo Roberto

    2003-01-01

    When domestic or industrial effluents with synthetic compounds are disposed without an adequate treatment, they impact negatively the environment with damages to aquatic life and for the human being. Both population and use of goods and services that contribute for the hazardous waste are growing. Hazardous regulations are becoming more restrictive and technologies, which do not destroy these products, are becoming less acceptable. The electron beam radiation process is an advanced oxidation process, that produces highly reactive radicals resulting in mineralization of the contaminant. In this work was developed an irradiation system in order to optimize the interaction of electron beam delivered from the accelerator with the processed effluent. It is composed by an irradiation device where the effluent presents to the electron beam in an up flow stream and a process control unit that uses the calorimetric principle. The developed irradiation device has a different configuration from the devices used by others researchers that are working with this technology. It was studied the technical and economic feasibility, comparing with the literature the results of the irradiation device demonstrated that it has a superior performance, becoming an process for use in disinfection and degradation of hazardous organic compounds of wastewater from domestic and industrial origin, contributing as an alternative technology for Sanitary Engineering.

    Brienza, Monica; Nir, Shlomo; Plantard, Gael; Goetz, Vincent; Chiron, Serge

    2018-06-08

    A tertiary treatment of effluent from a biological domestic wastewater treatment plant was tested by combining filtration and solar photocatalysis. Adsorption was carried out by a sequence of two column filters, the first one filled with granular activated carbon (GAC) and the second one with granulated nano-composite of micelle-montmorillonite mixed with sand (20:100, w/w). The applied solar advanced oxidation process was homogeneous photo-Fenton photocatalysis using peroxymonosulfate (PMS) as oxidant agent. This combination of simple, robust, and low-cost technologies aimed to ensure water disinfection and emerging contaminants (ECs, mainly pharmaceuticals) removal. The filtration step showed good performances in removing dissolved organic matter and practically removing all bacteria such as Escherichia coli and Enterococcus faecalis from the secondary treated water. Solar advanced oxidation processes were efficient in elimination of trace levels of ECs. The final effluent presented an improved sanitary level with acceptable chemical and biological characteristics for irrigation.

  16. Wastewater for agriculture: A reuse-oriented planning model and its application in peri-urban China.

    Science.gov (United States)

    Murray, Ashley; Ray, Isha

    2010-03-01

    The benefits of Integrated Water Resources Management (IWRM) are widely known but its recommendations remain thinly implemented. Designing wastewater treatment plants for reuse in irrigation is a particularly underutilized IWRM opportunity that could potentially increase agricultural yields, conserve surface water, offset chemical fertilizer demand, and reduce the costs of wastewater treatment by eliminating nutrient removal processes. This paper presents a novel planning model, consisting of a reuse-centric performance assessment and optimization model to help design wastewater treatment plants for reuse in agriculture. The performance assessment and optimization model are described, and their coupled application is demonstrated in the peri-urban district of Pixian, China. Based on the results of the performance assessment, two reuse scenarios are evaluated: wastewater to supplement business as usual (BAU) irrigation, and wastewater to replace BAU irrigation. The results indicate that wastewater supplementation could increase profits by $20 million (M) annually; alternatively, wastewater replacement could conserve 35Mm(3) of water in local rivers each year.

    Excessive world wastes production generates constant preoccupations with relation to its management. The methods of classic elimination as sanitary landfill controlled as compared to controvertible incineration and gasification plants as well as expectations created in connection with practices of recycling, its are intensive discussions motive between town halls, technical specialists, ecologists and general public. What is certain is that wastes in the last 30 years have been valued economically. Today the wastes are appreciated by certain sectors that begin to monopolize the recycling line because they see an excellent business. All methods of residues elimination produce at same time other wastes. Solid nature wastes generally end in the landfill and semi-liquid waste are dehydrated with same objective. In the present Thesis, without intending to say that the landfill processing will be the better option, is outlined the form of optimizing the utilization of same. It's demonstrated that landfill, furthermore to fulfil its sanitary function, are converted into an energetic alternative with utilization of flammable gas generated in them, something which represents an interesting value added if is converted into source of welfare for social and economically kernels, as happens in peripheries of the sanitary landfill at large Latin American cities. Of other side are considered principal aspects that intervene in methane gas generation and quality and utilization alternatives. Finally it is made emphasis in environmental situation at European and international level about the landfill gases, how is outlined greenhouse effect topic, what are environmental actions for year 2000 and are related some biogas utilization experiences at Europe

  1. Prospective technologies and equipment for sanitary hygienic measures for life support systems

    Science.gov (United States)

    Shumilina, I. V.

    Creation of optimal sanitary hygienic conditions is a prerequisite for good health and performance of crews on extended space missions. There is a rich assortment of associated means, methods and equipment developed and experimentally tested in orbital flights. However, over a one-year period a crew of three uses up about 800 kg of ground-supplied wet wipes and towels for personal needs. The degree of closure of life support systems for long-duration orbital flights should be maximized, particularly for interplanetary missions, which exclude any possibility of re-supply. Washing with regenerated water is the ultimate sanitary hygienic goal. That is why it is so important to design devices for crew bathing during long-term space missions. Investigations showed that regeneration of wash water (WW) using membrane processes (reverse osmosis, nanofiltration etc.), unlike sorption, would not require much additional expendables. A two-stage membrane recovery unit eliminated >85% of permeate from real WW with organic and inorganic selectivity of 82 95%. The two-stage WW recovery unit was tested with artificial and real WW containing detergents available for space crews. Investigations into the ways of doing laundry and drying along with which detergents will be the best fit for space flight are also planned. Testing of a technology for water extraction from used textiles using a conventional period of contact of 1 s or more, showed that the humidity of the outgoing air flow neared 100%. Issues related to designing the next generation of space life support systems should consider the benefits of integrating new sanitary hygienic technologies, equipment, and methods.

    The calculation of a sanitary impact present a great interest at the decision level for the decision-makers and the whole of concerned actors. It constitutes a first step to organize a social debate around the risk acceptance, to analyze the feasibility of an inquiry or an epidemiological surveillance or to proportion an activity leading to pollutants emission in natural medium. Several conclusions are brought out: it is justified to estimate a sanitary impact from a sanitary risk excess, especially coming from animal tissue. It is conceivable to go beyond an estimation of the only individual risk and to calculate a number of cases in excess in the concerned population. The working group underlines that the characteristics of the situation are the determining factor to give the type of response to bring. The effective of the population is an important element and a situation has not to be underestimated because of the size at the pretext that the excess calculation leads to a number of cases inferior to one leading to believe that the impact is minor or negligible while the individual probability is high. The sanitary impact, expressed by the number of cancer cases in excess in an exposed population is quantified from the average value of excess of sanitary risk multiplied by the population effective, and expressed with a confidence interval. The sanitary impact can be expressed under the form of a percentage of the population present in the exposure area and goes past the comparison marks usually pointed up. This practice must be cheered. An analysis of uncertainties must be made as often as possible. (N.C.)

  18. Quantum leap for treating wastewaters

    Full text: For many Australian food manufacturers there is increasing pressure from government agencies to reach higher standards of wastewater treatment for environmental discharge. In fact, throughout the western wolrd industrual water users are facing a similar challenge. One of the big problems is ageing pipe networks, particularly sewage pipes. Also, industrial wastewaters with high sugar-nutrient loads can cause serious damage to pipelines. This is because fermentation occurs within the wastewater, eroding and degrading the pipes, causing numerous cracks and fractures. This in turn leads to water ingress, which puts a strain on treatment plants because of the higher volume of water, especially in wet weather. Food manufacturing produces large volumes of mostly biodegradable liquid and solid waste. Wastewaters released from food manufacturing can be 'muddy', with high concentrations of suspended solids, fats, oils and grease (FOGs), and, usually, nutrients such as nitrogen. The issue for many food manufacturers is that existing wastewater treatment systems are unable to reduce the nutrient load in the biological treatment stage to a level allowing acceptable discharge. In addition, most rely on large tanks housing bacteria that are submerged in water and aerated. Aeration is energy-hungry and can create a 'sludge-cake' on top of the water, which is difficult to treat. Most existing technologies also use filters, but they foul easily and require ongoing maintenance. According to BioGill chief executive John West, the BioGill technology is groundbreaking and radically different from conventional bioreactors because the 'gills' are not submerged. Instead, the gills, composed of Nano-Ceramic Membrane sheets arranged vertically in pairs, are suspended in the air, above ground, with wastewater travelling down between them. “Fungi and bacteria, known as biomass, grow on the membranes in direct contact with the air, eating nutrients much faster than other systems

    Full Text Available Wastewater plants, mainly with secondary treatments, discharge polluted water to environment that cannot be used in any human activity. When those dumps are in the sea it is expected that most of the biological pollutants die or almost disappear before water reaches human range. This natural withdrawal of bacteria, viruses and other pathogens is due to some conditions such as the salt water of the sea and the sun effect, and the dumps areas are calculated taking into account these conditions. However, under certain meteorological phenomena water arrives to the coast without the full disappearance of pollutant elements. In Mediterranean Sea there are some periods of adverse climatic conditions that pollute the coast near the wastewater dumping. In this paper, authors present an automatic control that prevents such pollution episodes using two mathematical models, one for the pollutant transportation and the other for the pollutant removal in wastewater spills.

    Population expansion and industrial development has deteriorated the quality of freshwater reservoirs around the world and has caused freshwater shortages in certain areas. Discharge of industrial effluents containing toxic heavy metals such as Cd and Cr into the environment have serious impact on human, animal and aquatic life. In order to solve these problems, the present study was focused on evaluating and demonstrating potential of microalgae for bioremediation of wastewater laden with nitrogen (N) in the form of nitrates, phosphorous (P) in the form of phosphates, chromium (Cr (VI)) and cadmium (Cd (II)). After screening several microalgae, Chlorella vulgaris and algae taken from Pleasant Hill Lake were chosen as candidate species for this study. The viability of the process was demonstrated in laboratory bioreactors and various experimental parameters such as contact time, initial metal concentration, algae concentration, pH and temperature that would affect remediation rates were studied. Based on the experimental results, correlations were developed to enable customizing and designing a commercial Algae based Wastewater Treatment System (AWTS). A commercial AWTS system that can be easily customized and is suitable for integration into existing wastewater treatment facilities was developed, and capital cost estimates for system including installation and annual operating costs were determined. The work concludes that algal bioremediation is a viable alternate technology for treating wastewater in an economical and sustainable way when compared to conventional treatment processes. The annual wastewater treatment cost to remove N,P is ~26x lower and to remove Cr, Cd is 7x lower than conventional treatment processes. The cost benefit analysis performed shows that if this technology is implemented at industrial complexes, Air Force freight and other Department of Defense installations with wastewater treatment plants, it could lead to millions of dollars in

    Sanitary agents are the most exposed ones to the effects of insecticides in eradication campaigns since its preparation until its application inside and outside houses. The lack of protection equipment and misinformation on how to use the material properly increase the risk of intoxication. The aim of this work was to analyze the occupational history of vector control sanitary agents in Ceará State, Brazil and its effects on their health. Individual recorded interviews were done with 10 agents who verbally described their life history. The content of these interviews were analyzed through the following categories: agent profile, endemic controls, work conditions, risks and health changes. Health risk situations were described from acute and chronic intoxication to problems with alcoholism. The research showed that sanitary agents have been disrespected as human beings as well as their labor rights, showing negligence by their employers.

    Full Text Available The objective of this research was to evaluate the effects of using different herbicides as desiccants in pre - harvest and the effects of storage on the physiological and sanitary quality of azuki bean seeds ( Vigna angularis Willd. The experiment was arranged in a randomized complete block design in a split plot scheme, with four replications. Four herbicides were tested: paraquat (400 g a.i. ha - 1 , glufosinate ammonium (400 g a.i. ha - 1 , glyphosate (720 g a.i. ha - 1 , flumioxazin (30 g a.i. ha - 1 and a control without herbicide application. In the subplots seed quality was tested in two evaluation periods: at harvest and six months after harvest. Desiccant was applied when the azuki beans were physiologically mature. We assessed the physiological and sanitary quality of the seeds using a vigour and seed health test. The use of glyphosate resulted in a higher incidence of abnormal seedlings and reduced size and weight of the seedlings. With paraquat and flumioxazin the physiological quality was maintained and there was reduced pathogen infestation in the seeds six months after harvest. Storage affected the physiological quality of the azuki bean seeds.

    Full Text Available This article presents a critical review of scientific literature on waste sanitary landfills and its effects on human health, with an approach to the adverse effects that are most commonly associated to living near waste landfills. The health variables included were low birth weight, congenital abnormalities, some types of neoplasms, allergies, asthma and other respiratory diseases using the MEDLINE, LILACS and CAPES’ thesis post graduation database for systematic review. In spite of the fact that some studies indicate positive asssociation between health risks and living close to landfills, the majority of the studies, mainly the most recent ones, do not demonstrate a significant health risk in this condition. Some common limitations and bias of the work in the field are discussed. The lack of direct quantification of exposure, lack of prospective approach and no comparaison of the different types and quality of management of the residues are common limitations to most studies. So far, there is weak evidence to support significant epidemiological health risks associated to landfills. More interdisciplinary research should improve the knoledge of the health risks related to living in the proximity to sanitary landfills.

    Full Text Available OBJECTIVE: To verify the physical, functional, hygienic, and sanitary conditions of the food services of municipal schools located in the Brazilian Midwest region. METHODS: This is a cross-sectional study of 296 school food services conducted from February to June 2012. The food services were assessed by a semi-structured check list divided into the following sections: physical conditions, available equipment, food handlers' conduct, and food service cleaning processes and procedures. The study variables were classified as compliant or noncompliant with the regulations passed by the National Sanitary Surveillance Agency. RESULTS: Noncompliances were found in all study food services, especially with respect to food service conditions, and the wiring and plumbing in the food preparation area. In this section, 62.7 to 95.9% of the food services did not comply with nine out of the thirteen study items. The main problems were: poorly cleaned external areas, deteriorated walls, floors, ceilings, roofs, drains, and roof gutters; and unscreened doors and windows, allowing the entrance of insects; among others. The main noncompliance regarding processes and procedures was the uncontrolled temperature of the ready-to-eat foods. CONCLUSION: The conditions of the study food services are unsatisfactory for the production of safe meals, possibly compromising meal quality, food safety, and the effectiveness of the School Food Program.

    Full Text Available Determination of the flow characteristics is very important for the design of sanitary sewers in any area. In the present study these are determined in the running sewers for the two parameters; per capita flow contribution and the peak flow factor. ISCO area - velocity flow meter model 4250 is used for this purpose. The flow meter, before being used in the running sewers, is calibrated first in the Hydraulics and Hydrology Laboratory of the UTM (Universiti Teknologi Malaysia. During the study the flow meter is installed inside the manhole in 10 different phases in the months of June, August, September, and October 2005 to monitor the sewage flow running in it. Continuous data is recorded in the flow meter during the process and the recorded time varies between 47 hours 25 minutes and 128 hours 35 minutes. The rainfall data is also collected during the same time using an automatic rain gauge which recorded rainfall at every five minutes of interval. Both the parameters thus calculated are then compared with the Malaysian Standard for sewer design i.e. MS 1228:1991. The results show that higher values of these parameters are being used in the design of sanitary sewers and extensive study needs to be carried out to review these values for future use

    Phosphogypsum is a by-product of the phosphatic fertilizer production from the beneficiation of phosphate minerals (apatites). Produced in large quantities throughout the world and stored temporally in stacks, the final destination of this product is nowadays a subject of investigation. Due to the presence of radionuclides ( 226 Ra, 232 Th and 40 K, mainly), possible applications for the phosphogypsum must be verified for radiological safety. The goal of this paper was to elaborate a representative water flow conceptual model of a sanitary landfill for the safety assessment of the impact of using phosphogypsum as a cover material. For this, the ground water flow in variably saturated conditions and solute transport model HYDRUS-2D has been used for simulating the impact in the saturated zone of potential radionuclides leaching. The conceptual model was developed by collecting and analyzing the data from environmental license documentation of municipal sanitary landfills located on the State of Minas Gerais, Brazil. In order to fulfill the requirements of HDRUS-2D model in terms of the necessary parameters, the physical characteristics and typical configuration of the landfills, as well as the hydrogeological parameters of soils and aquifers related to the local of placement of the landfills, were taken in account for the formulation of the conceptual model.

    Full Text Available ABSTRACT The aim of this study was to evaluate the initial growth of sunflower seedlings under different concentrations of sanitary landfill leachate, considering the feasibility of its use as source of nutrients for agricultural production. Biometric and vigor variables were analyzed through the measurements of collar diameter, shoot height, number of leaves and shoot and root fresh and dry matters, from January to February 2015. The experimental design was completely randomized in a 5 x 4 factorial scheme: five leachate concentrations (0, 40, 60, 80 and 100 kg N ha-1 x four harvest periods (14, 21, 25 and 29 days after sowing, with five replicates each containing two plants. The data were subjected to analysis of variance and polynomial regression, and the results of the last harvest (29 DAS were compared by Tukey test (p ≤ 0.05. The use of sanitary landfill leachate increased all analyzed variables in sunflower plants when compared to the control plants (without leachate, especially in the treatment of 100 kg N ha-1. There was no inhibitory effect of the leachate on the initial growth of sunflower seedlings under adopted experimental conditions.

    Since the 1991 Y-12 Plant report, a flow study of the Y-12 Plant sanitary sewer collection system has been completed by the Y-12 Plant staff (Hanzelka and Maguire, 1993). Additional data has been obtained by the Y-12 Plant and the City of Oak Ridge (COR, 1994). COR developed limits on radionuclide concentrations in sludges used for land application (Stetar, 1993). Martin Marietta Energy Systems has provided recommendations to the Department of Energy (DOE) regarding the impacts of sludge land farming operations on the ORR (Frye, 1992). The DOE Office of Nuclear Safety (USDOE, 1993) completed an audit of activities related to radiological contamination of the COR sewer system due to DOE operations. In addition COR is currently developing limits on radionuclide releases for all industrial customers to be applied through the permitting process. In 1994, a new sanitary sewer monitoring station was installed and began operation at the Y-12 Plant to determine releases specifically from the Y-12 Plant. Previously, estimates were based on mass balance calculations using data from the City Monitoring Station which monitors Union Valley and Y-12 Plant releases. The purpose of this report is to update the 1991 Y-12 Plant study taking into account current data and information

    Full Text Available Soybean production accounts for approximately 43% of Brazil’s grain produce, worth over 81 million tons for the 2012- 2013 cropping season. The use of quality seeds is essential for a high-yield agriculture, since low quality seeds compromise plant standing and increase production costs due to reseeding. This will in turn reduce yields through delays on the establishment dates. Seed quality is affected by relative humidity levels, mechanical damage during harvest and processing, thermal damage during the drying process and the environmental conditions during storage that could foster insect and fungi damage. The climate in the state of Santa Catarina favors soybean seed production, and seed companies in general work with high levels of technology. This work is aimed at characterizing the physical and sanitary quality of soybean seeds produced by different companies at different locations throughout the state of Santa Catarina (municipalities of Xanxerê, Abelardo Luz, Campos Novos and Canoinhas. The physical purity, moisture level, sanitary quality and mechanical damage of soybean seeds were studied at three stages, i.e. reception at the seed processing unit, at the end of the processing process and before being marketed. Results pointed out at mechanical injury and cultivar mixture as the main issues concerning seed lot quality, and that soybean seeds produced in Santa Catarina show pathogen contamination, which emphasizes the need for seed treatment.

  13. District heating from Forsmark

    1980-11-01

    The district heating system of Greater Stockholm must be based on other energy sources than oil. Two alternatives are assessed, namely heat from Forsmark or a coal fueled plant in the region of Stockholm. Forsmark 3 can produce both electricity and heat from the year 1988 on. The capacity can be increased by coal fueled blocks. For low electricity use, 115 TWh in the year 1990, the Forsmark alternative will be profitable. The alternative will be profitable. The alternative with a fossile fuelled plant will be profitable when planning for high consumption of electricity, 125 TWh. The Forsmark alternative means high investments and the introduction of new techniques. (G.B.)

    The aim was to examine, critically, 19th century hospital sanitary reform with reference to theories about infection and contagion. In the nineteenth century, measures to control epidemic diseases focused on providing clean water, removing waste and isolating infected cases. These measures were informed by the ideas of sanitary reformers like Chadwick and Nightingale, and hospitals were an important element of sanitary reform. Informed by the paradigmatic tradition of social history, the study design was a historical analysis of public health policy. Using the methods of historical research, documentary primary sources, including official reports and selected hospital archives and related secondary sources, were consulted. Emerging theories about infection were informing official bodies like the Board of Superintendence of Dublin Hospitals in their efforts to improve hospital sanitation. The Board secured important reforms in hospital sanitation, including the provision of technically efficient sanitary infrastructure. Public health measures to control epidemic infections are only as effective as the state of knowledge of infection and contagion and the infrastructure to support sanitary measures. Today, public mistrust about the safety of hospitals is reminiscent of that of 150 years ago, although the reasons are different and relate to a fear of contracting antimicrobial-resistant infections. A powerful historical lesson from this study is that resistance to new ideas can delay progress and improved sanitary standards can allay public mistrust. In reforming hospital sanitation, policies and regulations were established--including an inspection body to monitor and enforce standards--the benefits of which provide lessons that resonate today. Such practices, especially effective independent inspection, could be adapted for present-day contexts and re-instigated where they do not exist. History has much to offer contemporary policy development and practice reform and

    The 1607-F3 waste site is the former location of the sanitary sewer system that supported the 182-F Pump Station, the 183-F Water Treatment Plant, and the 151-F Substation. The sanitary sewer system included a septic tank, drain field, and associated pipeline, all in use between 1944 and 1965. In accordance with this evaluation, the verification sampling results support a reclassification of this site to Interim Closed Out. The results of verification sampling demonstrated that residual contaminant concentrations do not preclude any future uses and allow for unrestricted use of shallow zone soils. The results also showed that residual contaminant concentrations are protective of groundwater and the Columbia River.

    The problem of water pollution acquires greater relevance in the context of a developing agrarian economy like Pakistan. Even though, the leather industry is a leading economic sector in Pakistan, there is an increasing environmental concern regarding tanneries because they produce large amounts of potentially toxic wastewater containing both trivalent and hexavalent chromium, which are equally hazardous for human population, aquaculture and agricultural activities in the area. Therefore, we defined the scope of the present study as to employ different bioassays to determine the eco-toxic potential of tannery effluent wastewater (TW) and its chromium based components, i.e., potassium dichromate (K(2)Cr(2)O(7)) and chromium sulfate Cr(2)(SO(4))(3). Particle-induced X-ray emission (PIXE) analysis of TW was carried out to determine the concentration of chromium in TW and then equal concentrations of hexavalent (K(2)Cr(2)O(7)) and trivalent chromium Cr(2)(SO(4))(3) were obtained for this study. Cytotoxicity assay, artemia bioassay and phytotoxicity assay was utilized to investigate the eco-toxicological potential of different concentrations of TW, K(2)Cr(2)O(7) and Cr(2)(SO(4))(3). All the dilutions of TW, K(2)Cr(2)O(7) and Cr(2)(SO(4))(3) presented concentration dependent cytotoxic effects in these assays. The data clearly represents that among all three tested materials, different dilutions of K(2)Cr(2)O(7) caused significantly more damage (P<0.001) to vero cell, brine shrimp and germination of maize seeds. Interestingly, the overall toxicity effects of TW treated groups were subsequent to K(2)Cr(2)O(7) treated group. Based on biological evidences presented in this article, it is concluded that hexavalent chromium (K(2)Cr(2)O(7)) and TW has got significant eco-damaging potential clearly elaborating that environmental burden in district Kasur is numerous and high levels of chromium is posing a considerable risk to the human population, aquaculture and agricultural

    This paper describes the geology of the Streltsovskoye uranium district located in south-eastern Zabaikalie region, Chita Province, Siberia, Russia. This district hosts Russia's only currently active uranium production centre. The uranium ore was discovered from 1963 to 1967 by drilling below fluorite veins which had minor associated uranium mineralization and radioactive anomalies. The uranium occurs as large scale vein stockwork deposits of hydrothermal origin within a volcano-tectonic caldera formed by continental volcanism of Late Mesozoic age. Rocks occurring in the caldera include basalt and trachydacite, overlain by rhyolite, and with associated interbedded sediments. The ore bodies occur in steeply dipping faults, with the greatest concentrations located where faults along the margins of the caldera intersect steeply dipping, cross cutting, northeasterly and northwesterly striking faults. The Streltsovskoye caldera extends over an area of 150 km 2 and is underlain by a large batholith. The 19 identified uranium deposits occurred in structural features that cut through the caldera sequence and extend into the basement rocks. The caldera has a maximum thickness of 1400 metres. Details of several deposits are given, including descriptions of mineralization and associated alteration. (author). 10 figs

    2013-01-01

    Full Text Available Changes in regulations and development of new technologies have affected the selection of alternative for treated wastewater disinfection. Disinfection is the last barrier of wastewater reclamation process to protect ecosystem safety and human health. Driving forces include water scarcity and drinking water supply, irrigation, rapid industrialization, using reclaimed water, source protection, overpopulation, and environmental protection. The safe operation of water reuse depends on effluent disinfection. Understanding the differences in inactivation mechanisms is critical to identify rate-limiting steps involved in the inactivation process as well as to develop more effective disinfection strategies. Disinfection byproducts discharged from wastewater treatment plants may impair aquatic ecosystems and downstream drinking-water quality. Numerous inorganic and organic micropollutants can undergo reactions with disinfectants. Therefore, to mitigate the adverse effects and also to enhance that efficiency, the use of alternative oxidation/disinfection systems should be evaluated as possible alternative to chlorine. This review gives a summary of the traditional, innovative, and combined disinfection alternatives and also disinfection byproducts for effluent of municipal wastewater treatment plants.

    2004-03-31

    In wastewater treatment, a method that specifically recognizes a variety of impurities in a flexible manner would be useful for treatment facilities with varying needs. Current purification techniques (i.e. bacteria, oxidation, reduction, precipitation and filtration) are nonspecific and difficult to control in complex mixtures. Heavy metal removal is particularly important in improving the efficiency of wastewater treatment, as they inhibit or even destroy the bacteria used for filtration. Imprinting polymerization is a technique that allows for the efficient removal of specific compounds and has been used in purification of enantiomers. It has potential to be applied in wastewater systems with the impurities acting as the template for the imprinting polymerization. The polymer with the bound impurities intact can then be removed via precipitation. After removal of the impurity the polymer can be reused. Data for the imprinting polymerization of polyacrylates and polyacrylamides for several metal complexes will be presented. Imprinting polymerization in combination with emulsion polymerization to improve the removal of hydrophobic contaminants will be described. Removal efficiencies will be presented and compared with conventional wastewater treatment methods.

    Physicochemical treatment of meat industry wastewater is used to increase the organic matter removal efficiency, and it generates great amounts of sludge. Treatment using commercial ferric sulfate as coagulant for this specific wastewater gave high organic matter removals, decreasing considerably the amount of waste material to be treated in biological systems, and also allowing the obtention of 0.83-0.87 kg of biomass fuel for each m{sup 3} of treated wastewater. Due to sanitary, environmental problems and operational costs related to the discharge, land disposal and re-use of wastes, the utilization of this Biofuel (dried sludge) for steam generation has shown to be a viable alternative. This type of fuel has a high heating value, and it is a renewable energy source. The combustion test with a Biofuel to sawdust ratio of 4:1 met the technical requirements for the characterization of this promising fuel; nevertheless, operating conditions must be well designed to achieve NO{sub X} and SO{sub 2} emissions below local and/or international limits.

    This study was designed to remove Pb(II) and Cd(II) from aqueous solution, shipyard wastewater, and sanitary landfill leachate using an alkaline-modified Rhizopus oryzae biomass. According to the Fourier transform infrared test, different functional groups like O–H, N–H, C=O, and P–O were detected in the bioadsorbent. The x-ray fluorescence (XRF) analysis showed that CaO, P2O3, and SO3 oxides have the highest content in the bioadsorbent. The surface area of modified Rhizopus oryzae was obtained as 20.32 m2 g‑1. The effect of initial pH, temperature, contact time, and bioadsorbent dose on the metals removal was discussed. At optimal conditions, maximum Pb(II) and Cd(II) removal was obtained 95.66% and 94.55%, respectively. Freundlich model was well- accurately described the equilibrium data. Among four studied models, the pseudo-second-order was better able to describe the kinetic behavior of the bioadsorption process. The amount of enthalpy, free energy of Gibbs, and entropy parameters indicated that the bioadsorption process of studied heavy metals is negative, exothermic, and spontaneous. The amount of heavy metals in a shipyard wastewater and sanitary landfill leachate was significantly decreased by using the developed bioadsorbent.

    An economic study of nuclear district heating is concerned with: heat production, its transmission towards the area to be served and the distribution management towards the consumers. Foreign and French assessments show that the high cost of now existing techniques of hot water transport defines the competing limit distance between the site and township to be below some fifty kilometers for the most important townships (provided that the fuel price remain stationary). All studies converge towards the choice of a high transport temperature as soon as the distance is of some twenty kilometers. As for fossile energy saving, some new possibilities appear with process heat reactors; either PWR of about 1000MWth for large townships, or pool-type reactors of about 100MWth when a combination with an industrial steam supply occurs [fr

    Wastewater from thirty onsite wastewater treatment systems was sampled during a reconnaissance field study to quantify bulk parameters and the occurrence of organic wastewater contaminants including endocrine disrupting compounds in treatment systems representing a variety of wastewater sources and treatment processes and their receiving environments. Bulk parameters ranged in concentrations representative of the wide variety of wastewater sources (residential vs. non-residential). Organic contaminants such as sterols, surfactant metabolites, antimicrobial agents, stimulants, metal-chelating agents, and other consumer product chemicals, measured by gas chromatography/mass spectrometry were detected frequently in onsite system wastewater. Wastewater composition was unique between source type likely due to differences in source water and chemical usage. Removal efficiencies varied by engineered treatment type and physicochemical properties of the contaminant, resulting in discharge to the soil treatment unit at ecotoxicologically-relevant concentrations. Organic wastewater contaminants were detected less frequently and at lower concentrations in onsite system receiving environments. Understanding the occurrence and fate of organic wastewater contaminants in onsite wastewater treatment systems will aid in minimizing risk to ecological and human health.

    2005-01-01

    The King County Wastewater Treatment Division (WTD) have concern about the aftermath of a radiological dispersion event (RDE) leading to the introduction of significant quantities of radioactive material into its combined sanitary and storm sewer system. Radioactive material could come from the use of a radiological dispersion device (RDD). RDDs include 'dirty bombs' that are not nuclear detonations but are explosives designed to spread radioactive material. Radioactive material also could come from deliberate introduction or dispersion of radioactive material into the environment, including waterways and water supply systems. Volume 2 of PNNL-15163 assesses the radiological instrumentation needs for detection of radiological or nuclear terrorism, in support of decisions to treat contaminated wastewater or to bypass the West Point Treatment Plant (WPTP), and in support of radiation protection of the workforce, the public, and the infrastructure of the WPTP. Fixed radiation detection instrumentation should be deployed in a defense-in-depth system that provides (1) early warning of significant radioactive material on the way to the WPTP, including identification of the radionuclide(s) and estimates of the soluble concentrations, with a floating detector located in the wet well at the Interbay Pump Station and telemetered via the internet to all authorized locations; (2) monitoring at strategic locations within the plant, including (2a) the pipe beyond the hydraulic ram in the bar screen room; (2b) above the collection funnels in the fine grit facility; (2c) in the sampling tank in the raw sewage pump room; and (2d) downstream of the concentration facilities that produce 6% blended and concentrated biosolids. Engineering challenges exist for these applications. It is necessary to deploy both ultra-sensitive detectors to provide early warning and identification and detectors capable of functioning in high-dose rate environments that are likely under some scenarios

    The results of radiological measurements of the north west mediterranean observation network outline the level of artificial radionuclides coming from industrial seewages, 106 Ru and from atmospheric fall out, 137 Cs and sup(239+240)Pu measured on 3 differents types of bioindicators: Mytilus sp., Posidonia oceanica (L.) Del. and demersal fishes as Solea sp., Anguilla anguilla L., Conger conger L. Mytilus sp. is quite a perfect bioindicator of radionuclides contamination but must be linked with fishes sampling which muscles concentrate Cesium at higher level. The sanitary consequences for the waterside population involved by molluscs and fishes ingestion contamined by these 3 radionuclides lead to a fraction (10 -5 ) of the annual dose limit recommanded by the ICRP 26 [fr

    The Savannah River Site is a 315 square mile, Department of Energy production facility located in western South Carolina. This facility has multiple operational areas which generate a variety of waste materials. Over the nearly 40 years of operation, sanitary wastes were deposited in a 60-acre, permitted solid waste disposal facility located on the site. Refuse and other clean wastes were deposited in shallow, slit trenches, ranging in size from 20 to 50 feet-wide and approximately 400 feet long. The historical depth of deposition appears to range between 12 and 15 feet below the ground surface. Recent changes in regulations has classified some wastes contained within the landfill as hazardous wastes, necessitating the closure of this facility as a RCRA hazardous waste management facility. The focus of this paper is to present the innovative techniques used to fully determine the engineering parameters necessary to reasonably predict future settlements, for input into the closure system design

    Full Text Available This research verified the influence of a Sanitary Landfill located at the Jockey Club of the Brasilia City (JCB on the chemical contents in the tree species of “Cerrado”. Six 25 x 500 m blocks were established in the PNB to sample the soil and the trees to chemical analysis. Three blocks were established near the landfill area and three in the control area. Nitrogen, phosphorus, potassium, calcium, lead, chromium, copper and mercury were analyzed. The highest nutrients and metals concentrations in soil were sampled in landfill adjacent area. The significant, crescent and directly proportional relationship (R2 > 0.80; p < 0.001 were observed between the elements concentration analyzed in soil with the leaves tissues. Therefore, the studied landfill presences increased nutrients and metals concentrations in soil and leaf tissue, fact that did not occur in the control area.

    Through the history of railways, wooden crossties impregnated with potentially hazardous creosote tar, have been used for years. There are six major classes of compounds in the creosote: aromatic hydrocarbons; tar acids/phenolics; tar bases/nitrogen-containing heterocycles; aromatic amines; sulfur-containing heterocycles; and oxygen-containing heterocycles. The creosote molecules applied in railway crossties can be released in the environment and they can bioaccumulate in animals and vegetables. Some constituents (benzo(a)pyrene and phenolics like benzene) are considered as being carcinogenic which renders the entire complex of creosote to be classified as potentially carcinogenic. After several decades of use the railway-ties are been recycled for varies uses like fences, stakes for agriculture and fruit production or bank protection. In this paper are examined some environmental and sanitary risks from wood impregnated with creosote reported in the literature.

    Environmental consequences from sanitary landfill as well as incineration with power generation were compared in terms of life cycle analysis (LCA) for Laohukeng Waste-disposal Plant that is under consideration in Shenzhen. A variety of differences will be resulted from the two technologies, from which the primary issue that affects the conclusion is if the compensatory phase in power generation can be properly considered in the boundary definition of LCA. Upon the compensatory phase is taken into account in the landfill system, the negative environmental consequences from the landfill will be more significant than those from the incineration with power generation, although the reversed results can be obtained as the compensatory phase is neglected. In addition, mitigation of environmental impacts through the pollutant treatment in the incineration process will be more effective than in the landfill process.

    Full Text Available The experiment was carried out in the years 2006-2008 in Bałcyny (N=53°35'49"; E=19°51'20". The aim of this study was to determine the effect of sulfur fertilization on the sanitary state of spring oilseed rape, winter oilseed rape, white mustard and Chinese mustard as well as on the species composition of fungi colonizing their seeds. Sulfur fertilization had a beneficial effect on the health of Brassicaceae plants infested by Alternaria blight, grey mould, Sclerotinia stem rot, Phoma stem canker and Verticillium wilt, but it had a varying effect on the occurrence of powdery mildew. Alternaria alternata and Penicillium spp. were isolated most frequently from Brassicaceae seeds. In general, more fungi (including pathogenic to Brassicaceae were isolated from the seeds of plants grown in non-sulfur fertilized plots. Pathogens occurred primarily on the seed surface, and their number decreased after surface disinfection of seeds.

    Problems of activity optimization of the sanitary and epidemiologic stations (SES) concerning state inspection of for radiation source application are considered to improve the effort efficiency of the radiological subdivisions. The necessity to specify the inspection objects is shown. Inspection of all the stages of creation, introduction and application of radioactive substances and other sources, as well as, of radioactive waste utilization remains urgent problem. Determination of internal and external radiation doses to population in different regions as well as, radiation protection of personnel and patients in nuclear medicine are vital problems as well. Justification of the necessity to enlist specialists in different fields, to determine rationally their functional duties presents sufficient component of the SES activity optimization. Usage optimization of dosimetric and radiometric devices, laboratory equipment and instruments is a vital problem

    Landfills are among the most common sources of pollution in ground water. Their widespread deployment, prolonged usage and the serious damage they cause to all of the elements of the environment are the reasons, which make the study of the problem particularly relevant. Most dangerous of all are the open dumps used until the middle of the twentieth century, from which large amounts of liquid emissions flowed freely (landfill infiltrate). In recent decades, the problem is solved by the construction of sanitary landfills in which they bury waste or solid residue from waste utilization plants. The bottom and the sides of the sanitary landfills are covered with a protective waterproof screen made of clay and polyethylene and the landfill infiltrate is led outside through a drainage system. This method of disposal severely limits any leakage of gas and liquid emissions into the environment and virtually eliminates the possibility of contamination. The main topic in the conducted hydrogeological study was a quantitative assessment of groundwater pollution and the environmental effects of re-landfilling of an old open dump into a new sanitary landfill, following the example of the municipal landfill of Asenovgrad, Bulgaria. The study includes: 1.A set of drilling, geophysical and hydrogeological field and laboratory studies on: -the definition and designation of the spatial limits of the main hydrogeological units; -identification of filtration parameters and migration characteristics of the main hydrogeological units; -clarifying the conditions for the sustentation and drainage of groundwater; -determininng the structure of the filtration field; -identifying and assessing the size and the extent of groundwater contamination from the old open dump . 2.Mathematical numeric models of migration and entry conditions of contaminants below the bottom of the landfill unit, with which the natural protection of the geological environment, the protective effect of the engineering

    With the notion of sustainable development gaining ground, practices aimed at saving water and energy are more and more frequent, particularly the installation of hydroelectric turbine on drinking water networks. It is essential in this case that the water quality should not be deteriorated, and the water supply for consumption and fire protection has to be prioritized over energy production. Thus, a sanitary risk assessment must be done and actions to control the described critical points have to be taken. The installation of a turbine is an additional risk whereas it is not necessary for drinking water production and distribution. As a consequence, a quality management system including the turbine and additional quality water monitoring should be carried out. (authors)

    Microbiological pollution of drinking water is a major health problem in the suburbs of the Albanian capital. Intermittent supply and contamination, resulting in several gastrointestinal manifestations, are the main concerns for the population and health workers. The risk of outbreaks of water-borne diseases is high. Pollution originates from contamination of drinking water with domestic sewage. This research investigated the drinking water cycle from its natural source to the consumer, analysing samples and verifying pollution levels in the microbiological and chemical setting. The most important pollution sources were found in the distribution network, due to cross-contamination with sewers and illegal connections. The second pollution source was found around the extraction wells. This is related to abusive constructions within the sanitary zone around the wells and maybe the highly sewage-contaminated river water which feeds the aquifer.

    The search for having access to health care and medicines right granted through Judicial Courts has increased in Brazil. What has been nominated "health judicialization" is a multidimensional phenomenon, a need for dealing with it in a multidisciplinary way involving legal-judicial, political-institutional and sanitary approaches has raised. The Health is recognized as a fundamental human right in the Brazilian Constitution giving it a different legal protection under the legal-constitutional order and the country guarantees the right to health are not only the Constitution and the law strictly, but mainly in an normative infralegal arc that define the goals and outcomes to be achieved by public policy. The lawsuits by drugs may be a reflection of the difficulty of access to health services, to empty and downgrading of health care. Therefore, this turns out to affect the judicialization of pharmaceutical care in Brazil.

  17. Sanitary hot water consumption patterns in commercial and industrial sectors in South Africa: Impact on heating system design

    International Nuclear Information System (INIS)

    Rankin, R.; Rousseau, P.G.

    2006-01-01

    A large amount of individual sanitary hot water consumers are present in the South African residential sector. This led to several studies being done on hot water consumption patterns in this sector. Large amounts of sanitary hot water are also consumed in the commercial sector in buildings such as hotels and in large residences such as those found in the mining industry. The daily profiles of sanitary hot water consumption are not related to any technical process but rather to human behavior and varying ambient conditions. The consumption of sanitary hot water, therefore, represents a challenge to the electrical utility because it is an energy demand that remains one of the biggest contributors to the undesirable high morning and afternoon peaks imposed on the national electricity supply grid. It also represents a challenge to sanitary hot water system designers because the amount of hot water as well as the daily profile in which it is consumed impacts significantly on system design. This paper deals with hot water consumption in the commercial and industrial sectors. In the commercial sector, we look at hotels and in the industrial sector at large mining residences. Both of them are served by centralized hot water systems. Measured results from the systems are compared to data obtained from previous publications. A comparison is also made to illustrate the impact that these differences will have on sanitary hot water system design. Simulations are conducted for these systems using a simulation program developed in previous studies. The results clearly show significant differences in the required heating and storage capacity for the new profiles. A twin peak profile obtained from previous studies in the residential sector was used up to now in studies of heating demand and system design in commercial buildings.

    Amongst all the different alternatives for the eliminator or treatment of MSW (Municipal Solid Waste), sanitary landfills is probably the one that is most widely employed to date, due to its economic advantages. With the coming into effect of the Spanish Containers and Packaging Law, alongside that of the Council Directive 1999/31/CE, concerning waste disposal, this situation will be substantially modified. At the same time, the application of said Directive will influence the amount of biogas generated in landfills. The present research work a study of the influence that the aforementioned Directive will have on the production of biogas in a sanitary landfill which currently disposes of around 400.000 Tm/year of MSW, 52% of which is easily biodegradable organic matter. The model proposed by Marticorena was applied and the kinetic parameters, MPO and d, were experimentally obtained by means of a pilot-plant study of MSW anaerobic degradation, the values employed being 173 Nm3 of biogas/Tm of the organic fraction of MSW for MPO, and 3 years for d. The results obtained in the model are compared with those obtained experimentally at the COGERSA landfill, Asturias, Spain. Twenty wells were chosen to analyse the production of biogas, giving an overall average yield of 70%. In 1999, around 4,100 m''3/h of biogas were extracted at the COGERSA landfill. Application of the model gave an estimation for 1999 of an average production of 5,369 m''3/h giving a maximum yield in the extraction of biogas of around 75%. The difference between the two average yields obtained may be due to the fact that the model only takes into account the easily biodegradable organic fraction, whilst in the landfill, given that more time has passed, other substances with a longer period of degradation, such as paper and cardboard, may also be degraded.

    Full Text Available Over the last decades, the emphasis on the health of dairy cows has changed from an individual to a herd level. In this scenario, the role played by the recording system and its interpretation by veterinarians has gained primordial importance. The records of productive and reproductive performance and of sanitary status from a southern Brazilian dairy cattle herd have been presented and discussed. The period of study was 2000-2009. Mean values per lactation period were 349D 8436M 290F 275P 201SCS (D: days in lactation, M: kg of milk yield, F: kg of fat, P: kg of protein and SCS: somatic cell score in 1000 cells/ml of milk. Major indexes of reproductive efficiency included age at first calving (31 months, services per conception (2.1, intercalving interval (428 days, calving to conception interval (146 days, mean annual rates of parturitions (76.2%, fetal losses (9.8-19.0%, and stillbirths (3.6%, apart of voluntary waiting period (94 days. Main information on sanitary status of the herd was associated with the mean prevalence of common disorders of dairy cattle such as anaplasmosis (29.8%, mastitis (27.8%, digital diseases (26.3%, ovarian cysts (21.3%, placental retention (19.7%, postpartum uterine infections (10.6%, and calf diarrhea (23.7% and pneumonia (16.8%, among others. In addition, culling reasons (low reproductive performance [56.3%] and udder/mastitis problems [33.6%], causes of cattle deaths (anaplasmosis [16.4%] and leukosis [11.4], and the impact of cattle diseases such as tuberculosis, leukosis, and neosporosis on the herd have also been presented and succinctly discussed. Numbers between brackets represent rates accumulated in the 10-year period.

    This work is carried out in Veracruz State covering over 11 jurisdictions of the State (Panuco, Tuxpan, Poza Rica, Martinez de la Torre, Xalapa, Cordoba, Orizaba, Veracruz, Cosamaloapan, San Andres Tuxtla and Coatzacoalcos). The sampling was realized in a period from 2009 to 2013 analyzing home drinking water, supply sources and wells, the sampling was done by the sanitary checkers of different jurisdictions with approved methods and the methodology was validated at the State Laboratory of Public Health. 1637 samples were analyzed by counting equipment Tennelec Canberra series 5 and a gas supply system P-10 with calibration curves for alpha and gross beta. The results of measurements ranging from 0.07 to 0.25 Bq/L in the activity concentration gross alpha annual average, an gross beta were from 0.12 to 0.17 Bq/L in the activity concentration gross beta annual average, and with a concentration range of alpha activity up to 0.62 and a minimum 0.02, and the concentration of beta activity of a maximum value 1.54 and a minimum 0.02, taking also as resulted in five years of analysis only 1.16% of the analyzed samples (19 samples) showed a value of alpha activity concentration above the minimum detectable concentration and 62.43% (1022 samples) of the analyzed samples showed a value of beta activity concentration above the minimum detectable concentration, is also clear that the results of the sanitary jurisdictions of Panuco and Tuxpan not have corresponding activity values for the years 2009, 2011-2013 except 2010. We can conclude that the regular measurements of alpha and gross beta activity in water are invaluable for timely detection of radioactive contamination. (Author)

  2. Sanitary and phytosanitary measures and food safety: challenges and opportunities for developing countries.

    2006-08-01

    Because of fast-growing demand, export markets can absorb high value added products and offer high returns; for many developing countries export market development is thus a key requirement for rural income generation and rural growth. Although developing countries face increasingly strict sanitary and phytosanitary standards in their export markets, they can maintain and improve market access--and improve domestic food safety and agricultural productivity--by adopting a strategic approach to food safety, agricultural health and trade. High-income countries should increase development flows to help developing countries build the capacity to plan and execute the necessary strategies. The first proposal in this paper is to make two existing sets of guidelines widely available to interested parties, in particular through the World Bank and the World Organisation for Animal Health (OIE). The first covers the broad process of problem assessment, strategy development and action plan formulation; the second set deals with institutional analysis and training of staff of the official sanitary control services. The second proposal is that interested countries and donors should speed up the ongoing development of guidelines, computer software tools and training material to help countries quantify the importance and impact of food safety issues. The focus here is on a 'multipurpose agricultural data analysis and modelization system'. The third proposal is to carry out a case study to help demonstrate that a number of animal health issues related to food safety should be treated as relating to 'global public goods' and thus require intervention on a global scale. Possible candidates are foot and mouth disease and highly pathogenic avian influenza.

    To study the strengths, weaknesses, opportunities, and threats of the Total Sanitation Campaign (TSC) in the Yavatmal district of Maharashtra. Data was collected in December 2006 through interviews with stakeholders, house-to-house surveys, focus group discussions, and transect walks. Information in each category was finalized in a meeting after brainstorming and discussion with the TSC cell members. The strengths of the campaign were innovations in Information Education and Communication, motivation through incentives, competitive spirit, active participation and partnerships, involvement of women, and universal coverage. The main weaknesses of the program were the absence of Rural Sanitary Marts/Production Centers, poor maintenance of Women Sanitary Complexes, lack of facilities for monitoring/ follow-up and a temporary focus of the campaign approach. There is an opportunity to tap additional resources, learn from other experiences, and institute back-up agencies to support and guide the community in the post-TSC phase. A change in administration and local leadership and loss of priority and interest needed to sustain the momentum while scaling up the interventions are possible threats for the program.

    The use of wastewater for rearing domestic animals is a common phenomenon in most of the developing countries like Pakistan that face a serious shortage of freshwater resources. However, most of the literature has only focused on the indirect effects of wastewater use on animal health or productivity, and literature on the direct effects of wastewater use is rare. Therefore, this study aims to investigate the direct and indirect effects of wastewater usage on the prevalence of animal diseases and animal health in Pakistan. The study is based on a household-level survey of 360 domestic water buffalo herds collected from 12 districts of Punjab Province, Pakistan. We tested the prevalence of the animal's diseases, animal's health, and wastewater-use preference with various econometric tools, such as the Poisson, negative binomial, and logistic regressions. The findings of the study show that the majority of the farmers use wastewater for buffalo bathing due to the shortage of freshwater resources. Results explore the prevalence of diseases such as clinical mastitis, tick infestation, and foot and mouth disease at the farm level significantly associated with buffalo bathing in the wastewater. Moreover, bathing in wastewater pre- and post-milking also plays a role in the occurrence of diseases. Particularly, if the buffalo's access to wastewater for bathing is within 60 min after milking, the probability of the animals being exposed to mastitis is higher. Furthermore, on investigation, a number of factors are found, such as the distance to the water source, power shortage, groundwater availability, and the education of farmers that influence farmers' behavior of letting their animals take a bath in wastewater. Moreover, the use of different preventive measures improves the animal's health.

    Full Text Available Water reuse and recycling, wastewater treatment, drinking water production and environmental protection are the key challenges for the future of our planet. Membrane separation technologies for the removal of all suspended solids and a fraction of dissolved solids from wastewaters, are becoming more and more promising. Also, these processes are playing a major role in wastewater purification systems because of their high potential for recovery of water from many industrial wastewaters. The aim of this work was to evaluate the application of micro and ultrafiltration for distillery wastewater purification in order to produce water suitable for reuse in the bioethanol industry. The results of the analyses of the permeate obtained after micro and ultrafiltration showed that the content of pollutants in distillery wastewater was significantly reduced. The removal efficiency for chemical oxygen demand, dry matter and total nitrogen was 90%, 99.2% and 99.9%, respectively. Suspended solids were completely removed from the stillage.

    Water and wastewater treatment and delivery is the most capital-intensive of all utility services. Historically underpriced, water and wastewater rates have exhibited unprecedented growth in the past fifteen years. Steep annual increases in water and wastewater rates that outpace the Consumer Price Index (CPI) have increasingly become the norm across the United States. In this paper, we analyze water and wastewater rates across U.S. census regions between 2000 and 2014. We also examine some of the driving factors behind these rate increases, including drought, water source, required infrastructure investment, population patterns, and conservation effects. Our results demonstrate that water and wastewater prices have consistently increased and have outstripped CPI throughout the study period nationwide, as well as within each census region. Further, evaluation of the current and upcoming challenges facing water and wastewater utilities suggests that sharp rate increases are likely to continue in the foreseeable future.

  13. Separation of Tritium from Wastewater

    International Nuclear Information System (INIS)

    JEPPSON, D.W.

    2000-01-01

    A proprietary tritium loading bed developed by Molecular Separations, Inc (MSI) has been shown to selectively load tritiated water as waters of hydration at near ambient temperatures. Tests conducted with a 126 (micro)C 1 tritium/liter water standard mixture showed reductions to 25 (micro)C 1 /L utilizing two, 2-meter long columns in series. Demonstration tests with Hanford Site wastewater samples indicate an approximate tritium concentration reduction from 0.3 (micro)C 1 /L to 0.07 (micro)C 1 /L for a series of two, 2-meter long stationary column beds Further reduction to less than 0.02 (micro)C 1 /L, the current drinking water maximum contaminant level (MCL), is projected with additional bed media in series. Tritium can be removed from the loaded beds with a modest temperature increase and the beds can be reused Results of initial tests are presented and a moving bed process for treating large quantities of wastewaters is proposed. The moving bed separation process appears promising to treat existing large quantities of wastewater at various US Department of Energy (DOE) sites. The enriched tritium stream can be grouted for waste disposition. The separations system has also been shown to reduce tritium concentrations in nuclear reactor cooling water to levels that allow reuse. Energy requirements to reconstitute the loading beds and waste disposal costs for this process appear modest

    The application of high intensity, low frequency ultrasound for the disinfection of simulated and septic tank wastewaters is evaluated in this work. Laboratory scale experiments were conducted at 24 and 80 kHz ultrasound frequency with horn-type sonicators capable of operating in continuous and pulsed irradiation modes at nominal ultrasound intensities up to 450 W. For the experiments with simulated wastewaters, Escherichia coli were used as biological indicator of disinfection efficiency, while for the experiments with septic tank wastewaters, the total microbiological load was used. Complete elimination of E. coli could be achieved within 20-30 min of irradiation at 24 kHz and 450 W with the efficiency decreasing with decreasing intensity and frequency. Moreover, continuous irradiation was more effective than intermittent treatment based on a common energy input. Irradiation of the septic tank effluent prior to biological treatment at 24 kHz and 450 W for 30 min resulted in a three-log total microbiological load reduction, and this was nearly equal to the reduction that could be achieved during biological treatment. Bacterial cell elimination upon irradiation was irreversible as no reappearance of the microorganisms occurred after 24 h

    Throughout history of European agglomerations in the nineteenth and twentieth century the relation between expanding industry and worsening sanitary and epidemiological conditions was seen. These changes, having great impact on public health, were investigated in the present study. Problems related to sanitary and epidemiological conditions in Lodz first emerged during the Russian occupation of Poland in the XIX century. The Russian Governing Council was not overseeing sanitary conditions of the city, and transferred this responsibility to the industrial bourgeoisie of Lodz. In this situation, uncontrolled development of the industry led to serious deterioration in natural environment and increase of risk for acute and chronic infectious diseases. Improvement of the sanitary situation in Lodz commenced in the period of the Second Polish Republic (1918-1939). Sanitary Divisions were created at the Lodz Department of Public Health. Activities in this Department involved, among others, detailed epidemiological examination of potable water, the investigation of manufacturing processes, retail and wholesale groceries, hygienic conditions of public housing. The activity and interventions of Sanitary Divisions contributed substantially to a decrease of incidence of various diseases and improvement of living conditions of the Lodz populations. The improvement of sanitary and epidemiological conditions in Lodz after 1918 was mainly related to the construction of water supply and sewage systems. This led to an approximation of the urban standards of this 500,000 population agglomeration to European standards.

    The treatment of wastewaters with high concentrations of organic compounds often represents a difficult problem. In some cases, for the destruction and removal of toxic compounds using processes like biological and chemical oxidation were proposed. Wastewaters from manufactured gas plants contain high concentrations of organic pollutants and ammonia. In this paper a technology for the treatment of these wastewaters is proposed. The experiments were realized with wastewaters from two Romanian manufactured gas plants. The process consists of the following steps: polycondensation-settling-stripping-biological treatment-electrocoagulation-electrochemical oxidation, or chemical oxidation. 6 refs., 4 tabs.

    In developing countries the awareness on the importance of sanitation facilities, whether it is for municipal solid waste or domestic wastewater treatment, is still very low. Jodipan and Ksatrian Village, in Malang, East Java, are two slum areas that have recently been improved visually by using simple colorful paints. The visual improvement was expected to increase the resident's awareness on the importance of keeping the area clean; adjacent to the project, a new municipal waste management system was also put in place, changing the president's behaviour towards municipal solid waste. This study focuses on the relationship between community awareness in municipal solid waste management and domestic wastewater management. The result is expected to be an input for the government to enhance wastewater infrastructure program and its sustainability, related to its awareness on municipal solid waste. A descriptive model through questionnaire to 48 households of Jodipan sub district in Kampung Warna-warni and 69 households of Ksatrian sub district in Kampung 3D by random sampling, with an error of 0.1, was used to conduct this research. A nonlinear relationship between the change in awareness in municipal solid waste management (MSW) and domestic wastewater management was observed, with only 0.1312 of determination coefficient. Weak Spearman correlation coefficient number was found, ranging from 0.284 to 0.39, indicating another parameter turned into a role on affecting the awareness of wastewater. Further study about another parameter (eg. social and economic parameter) intervension on sanitation awareness could be investigated.

    This report summarises results and experiences gathered from field trials with recycling of pre-treated wastewater, diverted human urine mixed with water, and municipal sludge, within plantations of willow species specifically selected for biomass production. Experimental sites were established in Sweden (Roma), France (Orchies), Northern Ireland (Culmore) and Greece (Larissa). The project was carried out during a 4-year period with financial support from the EU FAIR Programme. The experimental sites were supplied with primary effluent from municipal treatment plants (Culmore and Larissa), stored industrial effluent from a chicory processing plant (Orchies), biologically treated and stored municipal wastewater (Roma) and human urine mixture from diverting low-flush toilets mixed with water (Roma). Application rates of the wastewaters or the urine mixture were equivalent to the calculated evapotranspiration rate at each site. Wastewaters were also applied up to three times this value to evaluate any possible negative effects. Estimations and evaluations were carried out mainly concerning: biomass growth, potential biological attacks of the plantations, plant water requirements, fertilisation effects of the wastewater, plant uptake of nutrients and heavy metals from applied wastewater, possible soil or groundwater impact, sanitary aspects, and potentials for removal in the soil-plant filter of nutrients and biodegradable organic material from applied wastewater. The results clearly indicated that biomass production in young willow plantations could be enhanced substantially after recycling of wastewater resources. The impact on soil and groundwater of nutrients (nitrogen and phosphorus) and heavy metals (copper, zinc, lead and cadmium) was limited, even when the application of water and nutrients exceeded the plant requirements. Also, the soil-plant system seemed to function as a natural treatment filter for pre-treated (primary settled) wastewater, with a treatment

    Objective: The present study was aimed at evaluating the quality and the impact of an intervention involving inspection and education in mammography centers of the Federal District, Brazil. Materials and methods: Forty one mammography centers in the Federal District were studied in the period between 2000 and 2002. The intervention involved an initial inspection followed by a training activity and notification of mammography centers by the Federal District Sanitary Vigilance authority. The imaging quality was compared before and after the intervention. Results: None of the 36 centers which completed the study reached more than 90% compliance with the standard imaging quality prior to the interventions, whereas ten were above 90% afterwards. Major improvements were observed in chassis maintenance, breast compression and visualization of microcalcifications. Conclusion: Despite the availability of a great number of mammography centers in the Federal District, most of them did not meet the required quality standards. The intervention has shown to be effective for improving the imaging quality, however a continued action is required to solve the remaining problems and increase the impact of the program. (author)

    Global withdrawals of water to satisfy human demands have grown dramatically in this century. Between 1900 and 1945, water consumption increased by over six times, more than double the rate of population growth. This rapid growth in water demand is due to the increasing reliance on irrigation to achieve food security, the growth of industrial uses, and the increasing use per capita for domestic purposes. Given the seriousness of the situation and future risk of crises, there is an urgent need to develop the water-efficient technologies including economical treatment methods of wastewater and polluted water. In the Central Research Institute of Samsung Heavy Industries (SHI), many industrial wastewater including leachate from landfill area, wastewater from papermill, dyeing complex, petrochemical processes, etc. are under investigation with electron beam irradiation. For the study of treating dyeing wastewater combined with conventional facilities, an electron beam pilot plant for treating 1,000m{sup 3}/day of wastewater from 80,000m{sup 3}/day of total dyeing wastewater has constructed and operated in Taegu Dyeing Industrial Complex. A commercial plant for re-circulation of wastewater from Papermill Company is also designed for S-paper Co. in Cheongwon City, and after the successful installation, up to 80% of wastewater could be re-used in paper producing process.

    Full Text Available Use of wastewater for growing vegetables has become a common practice around big cities. Wastewater contains organic material and inorganic elements essential for plant growth but also contain heavy metals which may be lethal for animals and humans if their concentration increases than permissible limit. To monitor this situation, a survey was conducted to ascertain the addition of heavy metals into agricultural fields through wastewater irrigation and their translocation in to the edible parts of the vegetables. For this purpose, during year 2009-10, 25 sewage water, 76 soil, 40 leaf and 30 vegetable samples (tomato, spinach, carrot and cauliflower were taken from peri-urban area of Lahore district. These samples were analyzed for Zn, Cu, Fe, Mn, Pb, Cd and Ni contents. The analysis showed that in wastewater concentration of Cu (100 %, Mn (72 %, Ni (32 % and Cd (44% were higher than the safe limits while Zn, Fe and Pb concentration was below permissible limits. In soil DTPA extractable concentration of Zn, Cu, Fe, Mn, Pb, Ni and Cd was in safe limit and ranged between 1.30-8.02, 1.06 -5.42, 8.60-35.03, 8.7-30.07, 2.11-30.86, 0.28-1.76 and 0.05-0.52 mg kg-1 respectively. In vegetable, 100 % leaf and fruit samples were contaminated and accumulation of heavy metals was higher than the WHO/FAO recommended permissible limits.

    Full Text Available The preserved wastewater was treated by the upflow anaerobic sludge blanket (UASB reactor, the effects of the anaerobic time on COD, turbidity, pH, conductivity, SS, absorbance, and decolorization rate of the preserved wastewater were investigated. The results showed that with the increase of the anaerobic time, the treatment effect of the UASB reactor on the preserved wastewater was improved. Under the optimum anaerobic time condition, the COD removal rate, turbidity removal rate, pH, conductivity, SS removal rate, absorbance, and decoloration rate of the wastewater were 49.6%, 38.5%, 5.68, 0.518×104, 24%, 0.598, and 32.4%, respectively. Therefore, the UASB reactor can be used as a pretreatment for the preserved wastewater, in order to reduce the difficulty of subsequent aerobic treatment.

    For industrial wastewater with low impurity levels such as contaminated ground water, cleaning water and etc., purification only with electron beam is possible, but it should be managed carefully with reducing required irradiation doses as low as possible. Also for industrial wastewater with high impurity levels such as dyeing wastewater, leachate and etc., purification only with electron beam requires high amount of doses and far beyond economies. Electron beam treatment combined with conventional purification methods such as coagulation, biological treatment, etc. is suitable for reduction of non-biodegradable impurities in wastewater and will extend the application area of electron beam. A pilot plant with electron beam for treating 1,000 m 3 /day of wastewater from dyeing industries has constructed and operated continuously since Oct 1998. Electron beam irradiation instead of chemical treatment shows much improvement in removing impurities and increases the efficiency of biological treatment. Actual plant is under consideration based upon the experimental results. (author)

    Lack of basic infrastructure, poor knowledge of hygiene and practices in food service establishments can contribute to outbreaks of foodborne illnesses. The aims of this study were to investigate the food safety knowledge and practices of food handlers and to assess the sanitary conditions of food service establishments in Bahir Dar town. A cross-sectional study was conducted in Bahir Dar in May 2011 and data were collected using questionnaire and observation checklist on employees' knowledge of food hygiene and their practices as well on sanitary conditions of the food service establishments The median age of the food handlers was 22 years and among the 455 subjects 99 (21.8%) have had food hygiene training. Sixty six percent of the establishments had flush toilets whereas 5.9% of the establishment had no toilet. Only 149 (33.6%) of the establishments had a proper solid waste collection receptacle and there was statistically significant association between the sanitary conditions and license status of the establishments (p=0.01). Most of all, knowledge gap in food hygiene and handling practice was observed. In addition, there was statistically significant difference between trained (professional) handlers and non-trained handlers with regard to food hygiene practices (p<0.05). While more than 50% of the handlers prepare meals ahead of the peak selling time, more than 50% of the left over was poorly managed. This study revealed poor sanitary conditions and poor food hygiene practices of handlers. Educational programs targeted at improving the attitude of food handlers and licensing and regular inspections have been recommended.

    Quantifying rainfall-derived inflow and infiltration (RDII) in a sanitary sewer is difficult when RDII and overflow occur simultaneously. This study proposes a novel conductivity-based method for estimating RDII. The method separately decomposes rainfall-derived inflow (RDI) and rainfall-induced infiltration (RII) on the basis of conductivity data. Fast Fourier transform was adopted to analyze variations in the flow and water quality during dry weather. Nonlinear curve fitting based on the least squares algorithm was used to optimize parameters in the proposed RDII model. The method was successfully applied to real-life case studies, in which inflow and infiltration were successfully estimated for three typical rainfall events with total rainfall volumes of 6.25 mm (light), 28.15 mm (medium), and 178 mm (heavy). Uncertainties of model parameters were estimated using the generalized likelihood uncertainty estimation (GLUE) method and were found to be acceptable. Compared with traditional flow-based methods, the proposed approach exhibits distinct advantages in estimating RDII and overflow, particularly when the two processes happen simultaneously.

    Full Text Available Objective: To characterize the epidemiological and sanitary conditions of the city of Ushuaia (National Territory of Tierra del Fuego at a key time in its history- a time in which interethnic contact and the consolidation of the Argentine nation-state were intensified as two parallel and related processes. Materials and methods: All death certificates available for the period 1890-1930 were analyzed, as well as relevant government documents and secondary sources in order to ob¬tain the health profile of the city and its relationship with the country in the following aspects: type of epidemiological phase, mortality rates, population structure, and the structure in health¬care. Conclusions: There was a great relevance of infectious diseases, and specially tuberculosis, among the population of the city in general, and among the indigenous and criminal population in particular. This epidemiological profile showed the shortcomings of a national health system that was trying to establish at the time, especially in a region difficult to reach.

  7. Seasonal trends in vegetation and atmospheric concentrations of PAHs and PBDEs near a sanitary landfill

    St-Amand, Annick D.; Mayer, Paul M.; Blais, Jules M.

    Spruce needle and atmospheric (gaseous and particulate-bound) concentrations were surveyed near a sanitary landfill from February 2004 to June 2005. The influence of several parameters such as temperature, relative humidity, wind speed and direction, as well as increased domestic heating during the winter was assessed. In general, polybrominated diphenyl ethers (PBDE) and polycyclic aromatic hydrocarbons (PAH) concentrations in spruce needles increased over time and decreased following snowmelt with a minimum coinciding with bud burst of deciduous trees. Atmospheric concentrations of PBDE and PAH, both particulate-bound and gaseous phase, were linked to daily weather events and thus showed more variability than those in spruce needles. Highest PAH concentrations were encountered during the winter, likely reflecting increased emission from heating homes. Pseudo Clausius-Clapeyron plots revealed higher PBDE gaseous concentrations with increasing temperature, but showed no correlation between PAH gaseous concentrations and temperature as this effect was obscured by seasonal emission patterns. Finally, air mass back trajectories and local wind directions revealed that particulate-bound PBDEs, along with both gaseous and particulate-bound PAHs were from local sources, whereas gaseous PBDEs were likely from distant sources.

  8. PHYSIOLOGICAL AND SANITARY QUALITIES OF MAIZE LANDRACE SEEDS STORED UNDER TWO CONDITIONS

    2015-08-01

    Full Text Available The preservation of seed quality during the storage period depends not only on the conditions during production and harvesting but also on the storage and maintenance of appropriate storage product conditions. Thus, the aim of this study was to evaluate the physiological and sanitary qualities of maize landrace seeds stored under two conditions. The maize seed batch varieties Oito carreiras, Cabo roxo and Lombo baio were used. Tests included germination, first count, cold test, accelerated aging and sanity. Based on the results it was concluded that the physiological quality of these seed varieties decreased with the storage period. The major fungi identified in the maize seeds during storage were from the genera Aspergillus, Fusarium and Penicillium, which caused deterioration and reduction of the physiological quality. Storage using a paper bag at a temperature of 10 °C did not prevent the deterioration of maize seeds but was more effective at preserving the quality of the seed compared with a plastic bag at room temperature.

    The electro-Fenton oxidation of a concentrate from reverse osmosis of a sanitary landfill leachate, with an initial chemical oxygen demand (COD) of 42 g L -1 , was carried out using a carbon-felt cathode and a boron doped diamond anode. The influence of the applied current intensity, initial pH and dissolved iron initial concentration on the electro-Fenton process was assessed. For the experimental conditions used, results showed that the initial pH is the parameter that more strongly influences the current efficiency of the electro-Fenton process, being this influence more pronounced on the oxidation rate than on the mineralization rate of the organic matter. The increase in iron initial concentration was found to be detrimental, since the natural amount of iron present in the effluent, 73 mg L -1 of total iron and 61 mg L -1 of dissolved iron, was sufficient to ensure the electro-Fenton process at the applied intensities - 0.2-1.4 A. For the more favourable conditions studied, initial pH of 3 and natural iron concentration, it was found an increase in the organic load and nitrogen removals with the applied current intensity. For the highest current intensity applied, a COD removal of 16.7 g L -1 was achieved after 8-h experiments. Copyright © 2017 Elsevier Ltd. All rights reserved.

    There are many ways to eliminate the municipal solid wastes, but only a few help to treat them and to dispose of them suitably. Some of the forms to avoid the problems that the trash originate are: not to produce it, recycling it in a 100% or creating a fictitious market where its value is equal to or greater than the product that gave origin to it; in any case, these alternatives are not absolutely practical. The trash can be incinerated, be segregated, be recycled partially or also be arranged in sanitary landfills. Anyway, the trash has always existed and it will continue existing for sure.

    From the very beginning of the scout organization one of its main trends was the Samaritan service consisting in giving medical help to victims of disasters and acts of God. It became a domain of girls guide mainly. The articles describes a great commitment of the Polish girls guide in the medical assistance offered to their compatriots during the September campaign of 1939 and during the years of occupation from 1939 to 1945. It shows the education and training methods that prepared the girls to work with great dedication. From the first days of the war the girl guides started to work as nurses and orderlies in civil and military hospitals. They organized also their own hospitals and numerous first aid stations in bombed localities and roads frequented by fugitives escaping from the west parts of the country to the eastern territories. Under occupation, the girl guides organized their own underground medical service that collaborated strictly with military organization fighting for independence. Assisted by doctors they organized medical trainings for the members, collected medicines and sanitary materials, preparing themselves for the fights of the last part of the war. The girl guides organized groups of medical assistance of the National Army, which constituted a core of the organization medical service. During the "Storm" action several thousands of girls worked as orderlies that belonged to the combat troops of the National Army. The Warsaw insurrection was the greatest battle of soldiers of the National Army. The girls offered their help to thousands of soldiers and civilian victims.

    In accordance with 10 CFR 20, the US Nuclear Regulatory Commission (NRC) regulates licensees` discharges of small quantities of radioactive materials into sanitary sewer systems. This generic study was initiated to examine the potential radiological hazard to the public resulting from exposure to radionuclides in sewage sludge during its treatment and disposal. Eleven scenarios were developed to characterize potential exposures to radioactive materials during sewer system operations and sewage sludge treatment and disposal activities and during the extended time frame following sewage sludge disposal. Two sets of deterministic dose calculations were performed; one to evaluate potential doses based on the radionuclides and quantities associated with documented case histories of sewer system contamination and a second, somewhat more conservative set, based on theoretical discharges at the maximum allowable levels for a more comprehensive list of 63 radionuclides. The results of the stochastic uncertainty and sensitivity analysis were also used to develop a collective dose estimate. The collective doses for the various radionuclides and scenarios range from 0.4 person-rem for {sup 137}Cs in Scenario No. 5 (sludge incinerator effluent) to 420 person-rem for {sup 137}Cs in Scenario No. 3 (sewage treatment plant liquid effluent). None of the 22 scenario/radionuclide combinations considered have collective doses greater than 1000 person-rem/yr. However, the total collective dose from these 22 combinations was found to be about 2100 person-rem.

    To increase the remediation ability and life expectancy of a leachate channel in a sanitary landfill, the plants used for remediation were composted as a post-remediation management technique. Phragmites australis or Typha angustifolia used for phytoremediation in a landfill leachate channel was harvested and used as a co-composting material with sewage sludge. The macrophyte compost was applied to the slope of a landfill on which plants were introduced for revegetation and to plants grown in pots to test for acute effects of the compost. The compost of the macrophytes successfully increased soil moisture and nutrient contents both on the landfill slope and in the soil of the pot experiment. Additionally, the rates of photosynthesis and the nutrient contents increased for plants grown in macrophyte compost. Thus, the revegetation or restoration management of the landfill would improve with the macrophyte compost used as a soil conditioner. The harvest of the macrophytes has the additional benefit of improving the remediation function of the leachate channel. Therefore, to sustainably manage both the leachate channel and the landfill, the composting of post-remediation macrophytes is an environmentally friendly and economically affordable method.

    To know patients' perceptions about relational aspects and technical procedures when they are attended by the administrative staff in Health Centres. To assess the utility of two ways for measuring satisfaction. Cross-sectional study carried out in people attending the administrative sections of Health Centres for diverse reasons. Just after the interaction with the administrative they were interviewed using two different questions for assessing their opinions and satisfaction with communicational and technical aspects related with their demands. Descriptive analysis. Significant differences among mean was explored by χ(2) test. Open-ended questions were grouped in categories in a process involving three researchers independently. Over than 90% (360) of the attendees declared to be satisfied or very satisfied with the service received from the staff personal. Nevertheless, among 18-36% gave suggestions for improving the service after their consultation. Independently the domain explored, people suggested the communicational, personal capability, quality and quantity of explanations and waiting time as the main aspects to be improved. Surveys with open-ended questions are more useful to assess the quality of the attention the citizens receive from no-sanitary staff in Health Centres. These type of questions are also more useful for detecting problems and planning new interventions. Relational and informative issues seem to be the most prioritary areas to improve in this section of Health Centres. Copyright © 2010 SECA. Published by Elsevier Espana. All rights reserved.

    The consumption of lacteal desserts in the province of Santa Cruz de Tenerife is notably high. However, there are no legal standards in Spain regarding microbiological quality. For this reason, we have decided that it would be of interest to carry out a health-sanitary study of these products, with the aim of discovering their microbial content. 330 samples of lacteal desserts on sale in the province of Santa Cruz de Tenerife have undergone analysis. They have been divided into three groups: cream caramel (egg and vanilla) (80), mousse (60) and the third group, known as "other desserts", which includes custard and the rest of lacteal desserts not included in the previous groupings (190). Neither E. coli, Salmonella spp., Shigella spp., nor Staphylococcus aureus have been detected in any of the samples analysed. In spite of the fact that the results obtained do not reflect high microbiological contamination, we consider it necessary to lay down legal standards, with reference values, for these lacteal products, which will guarantee good microbiological quality.

    The purpose of this work is to analyze the process of importation, that is a part of the sanitary control of psychotropic substances, made by Brazilian National Health Surveillance Agency's ports, airports and borders. For this work, psychotropic substances are defined as active pharmaceutical raw materials present in the list B1 of Portaria nº 344/98; which need Anvisa's permission to be imported. For this purpose we used semistructured interviews with key informers and participant observation. The information were collected and systematized through the content analysis, thematic modality. The results show a very complex control which involves an intense bureaucratic process. The main identified critical points of the process were: the information system precariousness; the absence of human resources; deficiency of laboratorial support and infra-structure at customs. Anvisa's web page and the specific law are strong points of the process, but still needing improvements. We understood that despite of the progress made, there are many things to do for giving the country an efficient health control system to the importation of these substances.

  17. How to model a negligible probability under the WTO sanitary and phytosanitary agreement?

    Since the 1997 EC--Hormones decision, World Trade Organization (WTO) Dispute Settlement Panels have wrestled with the question of what constitutes a negligible risk under the Sanitary and Phytosanitary Agreement. More recently, the 2010 WTO Australia--Apples Panel focused considerable attention on the appropriate quantitative model for a negligible probability in a risk assessment. The 2006 Australian Import Risk Analysis for Apples from New Zealand translated narrative probability statements into quantitative ranges. The uncertainty about a "negligible" probability was characterized as a uniform distribution with a minimum value of zero and a maximum value of 10(-6) . The Australia - Apples Panel found that the use of this distribution would tend to overestimate the likelihood of "negligible" events and indicated that a triangular distribution with a most probable value of zero and a maximum value of 10⁻⁶ would correct the bias. The Panel observed that the midpoint of the uniform distribution is 5 × 10⁻⁷ but did not consider that the triangular distribution has an expected value of 3.3 × 10⁻⁷. Therefore, if this triangular distribution is the appropriate correction, the magnitude of the bias found by the Panel appears modest. The Panel's detailed critique of the Australian risk assessment, and the conclusions of the WTO Appellate Body about the materiality of flaws found by the Panel, may have important implications for the standard of review for risk assessments under the WTO SPS Agreement. © 2012 Society for Risk Analysis.

    Full Text Available Palytoxin (PLTX, one the most potent marine toxins, and/or its analogs, have been identified in different marine organisms, such as Palythoa soft corals, Ostreopsis dinoflagellates, and Trichodesmium cyanobacteria. Although the main concern for human health is PLTXs entrance in the human food chain, there is growing evidence of adverse effects associated with inhalational, cutaneous, and/or ocular exposure to aquarium soft corals contaminated by PLTXs or aquaria waters. Indeed, the number of case reports describing human poisonings after handling these cnidarians is continuously increasing. In general, the signs and symptoms involve mainly the respiratory (rhinorrhea and coughing, skeletomuscular (myalgia, weakness, spasms, cardiovascular (electrocardiogram alterations, gastrointestinal (nausea, and nervous (paresthesia, ataxia, tremors systems or apparates. The widespread phenomenon, the entity of the signs and symptoms of poisoning and the lack of control in the trade of corals as aquaria decorative elements led to consider these poisonings an emerging sanitary problem. This review summarizes literature data on human poisonings due to, or ascribed to, PLTX-containing soft corals, focusing on the different PLTX congeners identified in these organisms and their toxic potential.

    In accordance with 10 CFR 20, the US Nuclear Regulatory Commission (NRC) regulates licensees' discharges of small quantities of radioactive materials into sanitary sewer systems. This generic study was initiated to examine the potential radiological hazard to the public resulting from exposure to radionuclides in sewage sludge during its treatment and disposal. Eleven scenarios were developed to characterize potential exposures to radioactive materials during sewer system operations and sewage sludge treatment and disposal activities and during the extended time frame following sewage sludge disposal. Two sets of deterministic dose calculations were performed; one to evaluate potential doses based on the radionuclides and quantities associated with documented case histories of sewer system contamination and a second, somewhat more conservative set, based on theoretical discharges at the maximum allowable levels for a more comprehensive list of 63 radionuclides. The results of the stochastic uncertainty and sensitivity analysis were also used to develop a collective dose estimate. The collective doses for the various radionuclides and scenarios range from 0.4 person-rem for 137 Cs in Scenario No. 5 (sludge incinerator effluent) to 420 person-rem for 137 Cs in Scenario No. 3 (sewage treatment plant liquid effluent). None of the 22 scenario/radionuclide combinations considered have collective doses greater than 1000 person-rem/yr. However, the total collective dose from these 22 combinations was found to be about 2100 person-rem

    The Lawrence Livermore National Laboratory (LLNL) is the largest discharger of sewage treated by the Livermore Water Reclamation (LWRP), contributing approximately 7% by volume of the LWRP influent LILNL operations, as potential sources both of industrial pollutants and radioactivity, are therefore of particular concern to the LWRP. For this reason, LLNL has maintained vigorous wastewater discharge control and monitoring programs. In particular, the monitoring program has demonstrated that, except in a few rare instances, the concentration of contaminants in LLNL effluent have always remained below the appropriate regulatory standards. The exceptions have generally been due to inadvertent discharges of metals-bearing solutions produced by metal plating or cleaning operations

    This report jointly written by IPSN and InVS, reviews the sanitary consequences in France of the Chernobyl accident, which occurred in 1986. The first point is dedicated to a short presentation of the knowledge relative to the sanitary consequences of the Chernobyl accident in the high contaminated countries and to the risk factors of the thyroid cancer. Secondly, this report describes the main systems of epidemiological surveillance of health implemented in France in 1986 and in 1999, as well as the data of the incidence and mortality of thyroid cancer observed in France since 1975. In addition, this report presents an analysis of the risk of thyroid cancer related to radioactive contamination in France, for young people of less than 15 years of age who where living in 1986 in the highest contaminated areas of France (Eastern territories). For this purpose, the theoretical number of thyroid cancers in excess is evaluated for this population, on the basis of different available risk model. Finally starting from the results of risk assessment, there is a discussion about the relevance and the feasibility of different epidemiological methods in view of answering the questions related to the sanitary consequences of the Chernobyl accident. In conclusion, this report recommends to reinforce the surveillance of thyroid cancer in France. (author)

    Full Text Available Deaths by venomous animals are medical emergencies that can lead to death and thus constitute sanitary problems in some regions of the world. In the South of America, the accidents by these animals are a common sanitary problem especially in warm, tropical or subtropical regions, related with rural work in several countries. Argentina is located in the extreme South of South America and a minor part of the continental surface is in tropical or subtropical regions, where most of the accidents by venomous animals happen. However, in the big cities in the center and South of the country, with no relation to rural work, scorpionism, mostly due to the synanthropic and facultative parthenogenetic scorpion Tityus trivittatus, has become a sanitary problem in the last few decades. This scorpion is present in the biggest cities of Argentina and in the last decades has killed over 20 children in provinces of the center and north of the country, mostly in big cities. In addition, it seems that this species is growing and spreading in new regions of the cities. In this revision, some characteristics of this scorpion regarding its habitat, spreading in Buenos Aires city, combat measures and available treatments are discussed.

    Full Text Available The paper presents the results obtained in the course of a study on the concrete made of aggregate obtained from wastes of sanitary ceramics. Previous examinations proved high in strength and durability of concrete of this type, and it showed a resistance to high temperatures. The material was classified as a fireproof concrete. While searching for the optimal applications of such concrete, a series of examinations and analyses on its thermal energy storage (TES properties were performed. This paper describes the two-stage experiment on the thermal behavior of the concrete made with sanitary ceramic wastes during cooling processes in comparison to different building materials subjected to the same thermal conditions. On the basis of the thermal, infrared analysis, and suitable calculations, the thermal power and the ability of the composite to store thermal energy was estimated. Finally, it was stated that the concrete made of sanitary ceramic waste aggregate and alumina cement can be recommended as a heat-accumulating material, and in combination with high durability can be used, e.g., for the construction of fireplace bodies.

    2016-05-01

    Full Text Available The tannery industry is one of the most important economic sectors in many countries, representing an important economic field also in developing countries. Leather tannery industry is water intensive and originates highly polluted wastewater that contain various micropollutants raising environmental and health concerns. Tannery wastewater is difficult to treat biologically because of complex characteristics like high salinity e high content of xenobiotics compounds. After conventional treatment (i.e., chromium precipitation–primary sedimentation–biological oxidation–secondary sedimentation, effluents still do not meet the required limits, at least for some parameters such as BOD, COD, salinity, ammonia and surfactants. The leather industry is being pressured to search cleaner, economically as well as environmentally friendly wastewater treatment technologies alternative or integrative to the conventional treatment in order to face the challenge of sustainability. The most spread approach to manage tannery wastewater is the steam segregation before conveying wastewaters to in treatment plants that typically include pre-treatment, mechanical and physico-chemical treatment, biological treatment, and treatment of the generated sludge. Thus proper treatment technologies are needed to handle tannery wastewater to remove effectively the environmental benign pollutants. However among various processes applied or proposed the sustainable technologies are emerging concern. This paper, as the-state-of-the-art, attempts to revise the over world trends of treatment technologies and advances for pollution prevention from tannery chemicals and wastewater.

    1996-12-31

    This study assesses the number of industries in Pakistan, the total discharge of wastewater, the biological oxygen demand (BOD) load, and the toxicity of the wastewater. The industrial sector is a major contributor to water pollution, with high levels of BOD, heavy metals, and toxic compounds. Only 30 industries have installed water pollution control equipment, and most are working at a very low operational level. Priority industrial sectors for pollution control are medium- to large-scale textile industries and small-scale tanneries and electroplating industries. Each day the textile industries discharge about 85,000 m{sup 3} of wastewater with a high BOD, while the electroplating industries discharge about 23,000 m{sup 3} of highly toxic and hazardous wastewater. Various in-plant modifications can reduce wastewater discharges. Economic incentives, like tax rebates, subsidies, and soft loans, could be an option for motivating medium- to large-scale industries to control water pollution. Central treatment plants may be constructed for treating wastewater generated by small-scale industries. The estimated costs for the treatment of textile and electroplating wastewater are given. The legislative structure in Pakistan is insufficient for control of industrial pollution; not only do existing laws need revision, but more laws and regulations are needed to improve the state of affairs, and enforcement agencies need to be strengthened. 15 refs., 1 fig., 9 tabs.

    2014-06-01

    Full Text Available The underlying assumption of this study is that in order to retain the competitiveness while reaching for the EU targets regarding low-energy construction, district heating companies need to develop new business and service models. How district heating companies could broaden their perspective and switch to a more service-oriented way of thinking is a key interest of our research. The used methods in our study are house builder interviews and a questionnaire. With the help of these methods we discussed the potential interest in heating related services acquiring a comprehensive understanding of the customer needs. The results indicate the importance of certain criteria when choosing the heating system in households: easiness, comfort and affordability seem to dominate the house builders’ preferences. Also environmental awareness seems to be for many an important factor when making a decision about the heating of the house. Altogether, based on the results of this study, we suggest that the prospects of district heating could benefit from highlighting certain aspects and strengths in the future. District heating companies need to increase flexibility, readiness to adopt new services, to invest in new marketing strategies and improving the communication skills.

    Based on results obtained in the laboratory a WWTP composed of a septic tank and an aerated percolating filter packed with organic media was built for a school. The system can treat 18 m3 d(-1) and was operated with a hydraulic loading rate of 0.078 (m3 m(-2) d(-1). For 360 days different operational conditions including start-up; stabilization; operation with aeration and non aeration; effect of rainy season, breaks from activities due to holidays and restart; were monitored and described in the article. Once stabilized, the system was able to remove, without the need for mechanical aeration, 97% of BOD5, 71% of COD, 93% of TKN, 11% of PO(4-)-P, 95% of TSS, 96% of VSS, in addition to having a removal efficiency of 4 log units of Faecal Coliforms (FC) and 100% helminthes eggs (HE). With this quality, the treated wastewater can be chlorinated and reused to irrigate green areas and/or in toilets. Although sanitary wastewater has a high concentration of Total-N (250 mg L(-1)) and a C/N ratio of less than 1, the system removed 65% of Total-N. Finally it was observed that after non activity periods, there was neither system failure nor the need to re-stabilize the system.

    The purpose of the study was to investigate the potential for stabilization of sanitary landfills by injecting fly ash. The method is supposed to prevent differential settlements in landfills and by that to counteract damages in the final cover. Injecting fly ash may also affect the chemical development in a positive way and prevent metal leaching. Pilot experiments at the Tveta waste recycling center (Tveta Aatervinningsanlaeggning) have been performed in order to estimate if the grouting technology is a suitable method for sanitary landfills. Fly ashes from the combustion of bio fuels were used in these tests. A literature study and laboratory experiments in order to prepare the field experiments were also part of the project. About 100 tons of ash slurry were injected during the pilot experiments. This corresponds to a filling degree of approximately 12-16 % of the available pores in the landfill body. As a result of the pilot test, the following conclusions can be drawn: Ash can be mixed with water to a pumpable slurry which can be injected without hardening inside the equipment. Neither the waste nor the grouting material caused a backpressure during the injection and nothing indicates that the injected ash deforms the landfilled waste. The ash-water-slurry flows through the voids in the waste easily. Thus, the ash may dispread quite far from the injection holes. Using a more powerful equipment backpressure and movements in the waste might occur. It was not possible to estimate the flow required for backpressure in this study. Large variations are possible but for safety reasons the maximal pressure should be limited with regard to the expected stability in the actual area. The grouted ash will harden within the landfill body within a couple of days. It accumulates in hard but brittle lumps, which may result in an increased stability of the landfill. Further studies are necessary in order to evaluate how the stability is affected and what amounts of ash are

    Full Text Available This study examined the possibility of reusing the ceramic wastes of sanitary ware as coarse aggregate, in partial substitution (15, 20 y 25 % of natural coarse aggregates. Firstly, the characterization of recycled coarse ceramic aggregate was carried out subsequently proceeded to establish the parameters of dosage and manufacture of different concretes. Lastly, tests were conducted using these mixes to characterize physical and mechanical, and a study was carried out to identify the crystalline phases. Results showed that as the substitution proportion increased, the mechanical properties of the concrete improved, whilst physical properties remained practically constant. In view of these results, we conclude that it is possible to use this type of ceramic waste as coarse aggregate when mixing concrete destined for structural purposes.

    En este estudio se plantea la posibilidad de reutilizar los residuos cerámicos de sanitarios como árido grueso sustituyendo de forma parcial (15, 20 y 25 % al árido grueso natural. Para ello, se llevó a cabo la caracterización del árido cerámico reciclado y posteriormente se procedió a establecer los parámetros de dosificación y fabricación de los distintos hormigones. Finalmente, se realizó sobre los mismos unos ensayos de caracterización de las propiedades físicas y mecánicas, y un estudio de las fases cristalinas. Los resultados indican que a medida que se aumenta el porcentaje de sustitución se ven mejoradas las propiedades mecánicas de estos, mientras que las propiedades físicas se mantienen prácticamente constantes. A la vista de estos resultados se puede concluir que es posible la utilización de este tipo de residuo cerámico como árido grueso en la elaboración de hormigones con fines estructurales.

    The analysis of a long time period of time (about 17 years) of the professional exposure to ionising radiation of the workers of an accidents Mutual, that has its own personal Dosimetry Service, allows to establish a relation between the showed global reduction of the registered doses of the people exposed and the circumstances and actions that did it possible. The fact to carry out a dosimetric control is an essential factor directed to accomplish the objective of holding the doses as low as achievable, joined with the fact of passing more strict law. Those factors that fixed a reduction of the doses inherited by the sanitary exposed workers whose relation are demonstrated in this study. The collective dose inherited by the bunch of people exposed is the parameter suitable to measure and assess the time history at medium and long term of the exposure conditions of the workers, and identify the more relevant characteristics of the risk by ionising radiation at workplace. The conclusion of the time history analysis of the quantity shows that the total collective dose for more than a thousand people group, are strongly affected by the doses corresponding to less than a 1,5 % of the users. The number of people that have a value dose higher that the average, and the high value of the dose in some periods because of their activity lead to changes of the value of the collective doses that can be higher than 100%. This great uncertainty in the measured value needs more than ten months of control to guarantee the lowering of doses received. The decreasing doses observed are strongly related with the reduction of this relative short number of cases with incidences in the doses registered. An important part of the work is related to identifying the incidences registered, noticing the evolution and checking the most suitable actions to lower it. (Author) 4 refs

    The limitless world production of residuals generates constant concerns with relationship to its administration. The classic elimination methods as the drains controlled in front of the controversial incineration plants and gasification as well as the expectations created around the recycle practices, are reason of intense debates among city councils, specialist, environmentalist technicians and the public in general. The certain thing is that the residuals in the last 30 years have been valued economically. Today in day the residuals are appreciated by certain sectors that begin to monopolize the line of the recycle because they come them an excellent business. All the methods of elimination of residuals produce in turn others. Those of solid nature in general go to the drain, the semi-liquids becomes dehydrated for the same end. Presently work, without seeking to say that the employment of the drains is the best option, thinks about how it has more than enough they are possible to optimize its use.

    Spray irrigation was used to test the survival and efficiency of forage grasses as a concentrating mechanism for the inorganic waste elements in leachate from a municipal solid waste sanitary landfill. Lime (0.67 metric tonnes ha), rock phosphate, and superphosphate (each at 11.2 metric tonnes ha) were applied in a randomised complete block design to reed canarygrass Phalaris arundinacea L., tall fescue Festuca arundinacea Schreb., cv. Ky31, orchardgrass Dactylis glomerata L., bromegrass Bromus inermis Leyss., and bermudagrass Cynodon dactylon (L.) Pers. cvs. Midland and Tufcote. Leachate was applied by overhead rotary sprinklers in weekly 8-h applications from 22 October 1974 to 28 April 1975. The total application averages about 155 cm. Sprayed leachate contained about 500 ppM of Ca, 150 to 200 ppM of Na, Fe, and Cl, 50 to 100 ppM of Mn, K, Mg, and N, 2 to 5 ppM of Al, Sr, Zn, and P, and less than 0.5 ppM of Ni, Co, Cr, Cu, Pb, and Cd. Chemical oxygen demand (COD) decreased from approximately 7500 mg liter in water emerging from landfill drains to 5000 mg litre in sprayed leachate. Electroconductivity ranged from 3000 to 4000 ..mu..mhos cm and pH from 5.3 to about 5.5. Leachate irrigation appreciably increased Na, Fe, Mn, Cl, and S levels in all forages except orchardgrass. Lime significantly prevented Mn accumulation and benefited forage grass persistence. Reed canarygrass generally contained the highest levels of most elements and along with Tufcote bermudagrass was more leachate-tolerant than other grasses. Seasonal factors affected the uptake of several elements, e.g. Na, Fe, Mn, Zn, K and Co were significantly lower in regrowth cuttings as compared with first cuttings of Midland bermudagrass and reed canarygrass.

    Full Text Available Introduction. Shopping habits have changed over the past several years and consumers choose shopping centres, where they can spend time and visit restaurants. People usually wash hands before meals, but toilets in shopping centres are visited by hundreds of users every day which makes their cleanliness questionable. Therefore, the aim of this study was to assess the sanitary condition of electrical hand dryers in toilets of the selected shopping centres in Kraków. Material and methods. Air was sampled at the outlet of electrical hand dryers and surface swabs of hand dryers were taken in toilets of five shopping centres. Air sampling was conducted using the MAS-100 impactor. The number of mesophilic bacteria, fungi, actinomycetes, staphylococci and Escherichia coli was determined. The results of air analyses were compared with the limits provided by the Polish Standards on air quality. Results. The number of microorganisms varied between the studied centres. In terms of mesophilic bacteria and fungi the air was unpolluted. The concentration of actinomycetes however significantly exceeded the limits set by the Polish Standards. Numerous Escherichia coli were found both in the air and in swabs in one of the centres. However the number of E. coli and staphylococci did not exceed the minimum infective dose. Conclusions. The studies showed high concentrations of airborne actinomycetes and staphylococci. Also the presence of E. coli in the air and swabs allows the conclusion that legal regulations for concentrations of airborne microorganisms are necessary to make people aware of this problem. However, it was found that using electrical hand dryers does not have impact on human health.

    In samples of 15 fodder phosphates a proper activity of natural radionuclides K-40, Ra-226 and Th-228 was determined. It was found that the content of K-40 in the examined phosphates was from 0 to 113.6 mBq/g (0-3.07 pCi/g), Ra-226 from 5.6 to 2523.4 mBq/g (0.15-68.2 pCi/g) and Th-228 from 11.1 to 100 mBq/g (0.3-2.7 pCi/g). On the basis of the obtained data the quantity of uranium in fodder phosphates and the quantity of Ra-226 transmitted into milk of cows fed on these phosphates was estimated. It was found that the quantity of uranium in phosphates was harmless for animals. It was admitted that the criterion of phosphates evaluation on the basis of quantity of Ra-226 transmitted into milk is not sufficient for drawing conclusion about their sanitary value. For a complex evaluation of fodder phosphates a limit value of radioactive activity of Ra-226 37 mBq/g (1 pCi/g) is proposed. Considering the possibility of air pollution in fodder factories a disuse of phosphates in production in which the activity of Ra-226 increases to 0.37 mBq/g (10 pCi/g) and of Th-228 to 75 mBq/g (2pCi/g) was proposed. The proposed criterion of evaluation concerns all phosphates used in Poland. (author)

    In this study, characterization and anaerobic treatability of leachate from Komurcuoda Sanitary Landfill located on the Asian part of Istanbul were investigated. Time based fluctuations in characteristics of leachate were monitored for an 8 month period. Samples were taken from a 200 m3 holding tank located at the lowest elevation of the landfill. COD concentrations have ranged between 18,800 and 47,800 mg/l while BOD5 between 6820 and 38,500 mg/L. COD and BOD5 values were higher in summer and lower in winter due to dilution by precipitation. On the other hand, it was quite interesting that such a dilution effect was not observed for ammonia. The highest ammonia concentration, 2690 mg/L was in November 1998. BOD5/COD ratio was larger than 0.7 for most samples indicating high biodegradability, and acidic phase of decomposition in the landfill. For anaerobic treatability, three different reactors, namely an upflow anaerobic sludge bed reactor, an anaerobic upflow filter and a hybrid bed reactor, were used. The anaerobic reactors were operated for more than 230 days and were continuing operation when this paper was prepared. Organic loading was increased gradually from 1.3 kg COD/m3.day to 8.2 kg COD/m3.day while hydraulic retention time was reduced from 2.4 days to 2.0 days. All the reactors showed similar performances against organic loadings with efficiencies between 80% and 90%. However the reactors have experienced high ammonia concentrations several times throughout the experimental period, and showed different inhibition levels. Anaerobic filter was the least affected reactor while UASB was the most. Hybrid bed reactor has exhibited a similar performance to anaerobic filter although not to the same degree.

    The onset of menstruation is one of the most important physiological changes occurring among girls during the adolescent years. Menstruation heralds the onset of physiological maturity in girls. It becomes the part and parcel of their lives until menopause. Apart from personal importance, this phenomenon also has social significance. In India, menstruation is surrounded by myths and misconceptions with a long list of "do's" and "don'ts" for women. Hygiene-related practices of women during menstruation are of considerable importance, as it may increase vulnerability to Reproductive Tract Infections (RTI's). Poor menstrual hygiene is one of the major reasons for the high prevalence of RTIs in the country and contributes significantly to female morbidity. Most of the adolescent girls in villages use rags and old clothes during menstruation, increasing susceptibility to RTI's. Adolescents constitute one-fifths of India's population and yet their sexual health needs remain largely unaddressed in the national welfare programs. Poor menstrual hygiene in developing countries has been an insufficiently acknowledged problem. In June 2010, the Government of India proposed a new scheme towards menstrual hygiene by a provision of subsidized sanitary napkins to rural adolescent girls. But there are various other issues like awareness, availability and quality of napkins, regular supply, privacy, water supply, disposal of napkins, reproductive health education and family support which needs simultaneous attention for promotion of menstrual hygiene. The current article looks at the issue of menstrual hygiene not only from the health point of view, but also considers social and human rights values attached to it.

    Full Text Available Internationalization consists of extending an organization's operations abroad. It involves decisions based on objective criteria and on an evaluation of strategies for entering the foreign market. The problem addressed in this study concerns a Brazilian firm’s difficulties developing its operations abroad. Thus, the purpose of this study was to identify the internationalization process of an industry in the sanitary ware segment in the development of its operations in another country. The research method employed was the single case study and data was collected by means of a semi-structured research script applied to company executives. The results showed that the internationalization process is characterized by the dynamic learning model (Uppsala Model, according to which an organization develops its activities abroad gradually, as it acquires experience and expertise in the market. The company is attempting to overcome cultural barriers and psychic distance in a slow internationalization process, aligned with the differentiation strategy and focus that it uses in the Brazilian market. This strategy comprises a sequence of planned and deliberate steps, with low investment exposure and risk. It was found that the firm adopts a strategy of exporting through distributors, this being a critical success factor, but that the distributor approval and development process lacks robust and formalized structuring. There are opportunities for improvement in the process of competitive intelligence in order to systematize the search and interpretation of information about the markets in which the company wants to operate.  Key-words: Internationalization of companies.

    The proposed paper covers the various aspects of control and monitoring of potential landfill gas (LFG) migration through soil voids or rock fractures at the City of Montreal sanitary landfill site. It depicts the social, geographical and geological context and presents a brief history of the landfill site. It describes the LFG collecting system and LFG migration monitoring equipment and programs. Finally it presents monitoring data taken over last few years. The landfill site is located in a well populated urban area. Since 1968, about 33 million metric tons of domestic and commercial waste have been buried in a former limestone quarry. Because of houses and buildings in the vicinity, 100 m in some locations, LFG underground migration is a major risk. LFG could indeed infiltrate buildings and reach explosive concentrations. So it must be controlled. The City of Montreal acquired the site in 1988 and has progressively built a LFG collecting system, composed of more than 288 vertical wells, to pump out of the landfill 280 million m 3 of gas annually. To verify the efficiency of this system to minimize LFG underground migration, monitoring equipment and programs have also been designed and put into operation. The monitoring network, located all around the landfill area, is composed of 21 well nests automated to monitor presence of gas in the ground in real time. In addition, 55 individual wells, where manual measurements are made, are also available. To complete the monitoring program, some measurements are also taken in buildings, houses and underground utilities in the neighborhood of the site. Monitoring data show that LFG underground migration is well controlled. They also indicate significant decrease of migration over the years corresponding to improvements to the LFG collecting system

    A characterization study has been conducted at Gongju Livestock Wastewater Treatment Plant, Gongju, South Korea. It is owned and operated by the government with treatment capacity of 250 tons per day. Livestock wastewater was collected from individual farmer and treated at the treatment plant. The centralized livestock wastewater treatment plant has various treatment processes namely pre-treatment, anaerobic digestion, nitrification, de-nitrification , chemical treatment, sand filtration and ozonization. The livestock wastewater was characterized by high COD, SS, T-N and T-P with concentration of 20600 mg/l, 6933 mg/l, 2820 mg/l and 700 mg/ l, respectively. After the wastewater has undergone various treatment processes it was discharged to waterways with concentration of COD, SS, T-N and T-P at 105 mg/l, 73 mg/l, 2.1 mg/l and 9 mg/l, respectively. This is part of the study to investigate the potential of irradiation to be applied at the centralized livestock wastewater treatment plant. Although livestock wastewater can be potentially applied to crop as source of nutrients it also affect the water quality due to runoff and leaching. When the wastewater applied at the rates in excess of crop uptake rates, the excess wastewater could potentially enter surface and groundwater and polluted them. (author)

  9. Characteristics and Biodegradability of Wastewater Organic Matter in Municipal Wastewater Treatment Plants Collecting Domestic Wastewater and Industrial Discharge

    Full Text Available Municipal wastewater treatment plants (WWTPs in Korea collect and treat not only domestic wastewater, but also discharge from industrial complexes. However, some industrial discharges contain a large amount of non-biodegradable organic matter, which cannot be treated properly in a conventional biological WWTP. This study aimed to investigate the characteristics and biodegradability of the wastewater organic matter contained in the industrial discharges and to examine the fate of the industrial discharges in a biological WWTP. In contrast to most previous studies targeting a specific group of organic compounds or traditional water quality indices, such as biological oxygen demand (BOD and chemical oxygen demand (COD, this study was purposed to quantify and characterize the biodegradable and nonbiodegradable fractions of the wastewater organic matter. Chemical oxygen demand (COD fractionation tests and fluorescence spectroscopy revealed that the industrial discharge from dyeing or pulp mill factories contained more non-biodegradable soluble organic matter than did the domestic wastewater. Statistical analysis on the WWTPs’ monitoring data indicated that the industrial discharge containing non-biodegradable soluble organic matter was not treated effectively in a biological WWTP, but was escaping from the system. Thus, industrial discharge that contained non-biodegradable soluble organic matter was a major factor in the decrease in biodegradability of the discharge, affecting the ultimate fate of wastewater organic matter in a biological WWTP. Further application of COD fractionation and fluorescence spectroscopy to wastewaters, with various industrial discharges, will help scientists and engineers to better design and operate a biological WWTP, by understanding the fate of wastewater organic matter.

    Complete text of publication follows. Ozone is forming with high enough radiation chemical yield during work of electron accelerator. It is useful to use oxidizing properties of ozone with combination of ionizing radiation. The combined action of ionized radiation and ozone on aqueous solutions increases efficiency of water purification. But at the same time, this kind process of water purification is characterized by some limited stages: 1. Ozone mass transfer rate from gaseous phase (where it is formed) into liquid phase (where pollutants present); 2. Small solubility ozone in water; 3. High rate constant of radiation induced decomposition of ozone. We have proposed some optimizations for this kind of process. The most effective action of ionized radiation and radiolytic ozone on polluted water is running this process in aerosol flow. The highly developed surface of phase division is provided the maximum rate of reaction of ozone with pollutants. The volatile pollutants react with radiolytic ozone in gaseous phase in ozone creation moment. Ozonoradiolysis of real municipal wastewater in an aerosol flow was investigated on a facility with electron accelerator with electron energy E=0,3 MeV, power up to 15 kWatt, productivity 500 m 3 /day. Density of the irradiated aerosol was 0,02-0,05 g/cm 3 . It is increase low-energy electron range on 1-2 orders of magnitude as compared with liquid water and increases effective depth of uniformed irradiated layer. Because aerosol density is much higher compare with air density, it is clear, that water drops in aerosol flow absorbed main energy. The treated municipal wastewater in this facility was cleaned from organic and inorganic pollutants. COD and BOD values were reduced. Water disinfecting is achieved to sanitary standards

    Cultures of duckweed (Lemna gibba and L. minor) were made for 2 months in 2 ponds fed by a semicontinuous flow of partially treated animal wastewaters. The growth rate of the organic load were obtained from weekly data and the rate of removal of N and P was evaluated. At high loads (concentrations greater than 400 COD, 60 NH/sub 4/+, 10 mg/L PO/sub 4/ to the power of 3-) an average yield (dry weight) of approximately 7 g/square meters/day was established. The mean dry weight of biomass was 6%. The N and P content in duckweed was 1.1 and 4.7%, respective, and the daily absorption rates were 415 N and 97 mg/square meters/day P. The technique of skimming biomass at a rate proportional to the growth rate is useful to maintain duckweed cultures in continuous active growth conditions.

    Analysis of epidemic manifestations of natural-foci infections (NFI), clarification of spectrum of their causative agents, determination of epizootic activity of natural foci in the Crimea Federal District (KFD). Epizootologic examination of 10 administrative districts of KDF was carried out. 291 pools (2705 specimens) of ixodes ticks and 283 samples of organs of small mammals were studied by PCRmethod for the presence of DNA/RNA of causative agents of a number of NFI. Morbidity by NFI in KFD was registered by 6 nosologies: Lyme borreliosis, Marseilles fever, leptospirosis; tularemia, intestine yersiniosis and tick-borne viral encephalitis, wherein, transmissive infections made up 91.6%. Circulation of causative agents of Crimea hemorrhagic fever, Q fever, group of tick-borne spotted fever, Lyme borreliosis, human granulocytic anaplasmosis, human monocytic ehrlichiosis, hemorrhagic fever with renal syndrome, West Nile fever, tularemia and leptospirosis was established. Due to activity of natural foci of NFI further monitoring of epidemiologic and epizootologic manifestations of these infections in the Crimea, including using genetic methods of analysis, is necessary for ensuring sanitary-epidemiologic welfare of KFD population.

    The company 'Societe Nouvelle du Radium' extracted radium and produced radium needles in Gif-sur-Yvette (Essonne) from 1904 to 1957. In 1959, this site was converted into a habitable zone. Since then, this district called the 'Petite Coudraie' has been going through several radioactivity measurements and decontamination works. In 2000, the detection of very high levels of radon above sanitary recommendations in one house encouraged the local authorities to launch a systematic investigation and risk analysis in order to take the necessary measures against radiological risks for the whole concerned district. The 'Direction Departementale des Affaires Sanitaires et Sociales' (D.D.A.S.S.), the French Institute of Public Health (InVS) and the Institute of Nuclear Protection and Security (I.P.S.N.) conducted a health impact assessment of the pollution in this area. The Office for the Protection against Ionizing Radiations (O.P.R.I.) and the I.P.S.N. first measured the radioactivity found on the surface area. The I.P.S.N. then conducted a dosimetric study based on the measurement results and realistic exposure scenarios of adults and children present in the area. Finally, on the base of these results, the InVs did a quantitative risk assessment of cancer due to exposure to the radioactive residuals from the past industrial activities which is the subject of this report. This assessment allows to estimate the extent of this potential health impact due to the contamination of the area with the current scientific knowledge. It assesses the contribution of the various sources ways of exposure to risk and therefore directs the measures of management priority. Finally, it also allows to appreciate the relevance of an epidemiological study on the population who was present in this area. (author)

  20. Quality of concrete plant wastewater for reuse

    Directory of Open Access Journals (Sweden)

    H. M. Paula

    Full Text Available Efficient water use is one of the most important requirements of cleaner production, and the use of the wastewater from concrete production can be an important means to this end. However, there are no Brazilian studies on the quality of concrete plant wastewater and the activities in which such water can be used. This paper aims to evaluate the quality of concrete plant wastewater and to propose guidelines for its treatment for non-potable applications. Wastewater samples were collected from three points in the studied treatment system, and tests were later performed in the laboratory to evaluate the water quality. The results obtained were compared with the limit values for the quality parameters that have been used for the analysis of the non-potable water supply in Brazil. The results indicate a need to at least add coagulation and pH correction processes to the treatment system.
