1. Methodology for minimum nitrogen compounds removal efficiencies estimation and wastewater treatment systems pre-selection: a watershed approach
RESUMO O nitrogênio constitui importante parâmetro para o controle da poluição hídrica, uma vez que a nitrificação produz consumo de oxigênio do ambiente aquático, além da toxicidade associada à algumas formas de nitrogênio. Este estudo estabeleceu e empregou modelo de otimização visando a determinação simultânea de eficiências mínimas de

3. Desempenho de tanques vegetados em um ecossistema engenheirado para tratamento descentralizado de esgotos domiciliares na Ilha Grande, RJ / Performance of vegetated tanks in an engineered ecosystem for decentralized treatment of sewage in Grande Island, RJ
The lack of appropriate infrastructure for sewage collection and treatment affects several communities living under unhealthy conditions in coastal areas and in insular systems in Rio de Janeiro State. The objective of this study was to assess the performance of an engineering ecosystem for the descentralized treatment of domestic wastewater located at the C

4. Caracterização do conteúdo de fossas e tanques sépticos na cidade de Natal
Only 32% of the population of Natal is attended by sewage, while the remaining population use pits and septic tanks. The characterization of the contents of septic tanks and pits contributes to the performance of such system and may guide the decision on treatment of these contents. The main of this research is to characterize the contents of interior reside

5. Characterization and treatment of sludge originated from septic tanks / Caracterização e pré-tratamento de lodo de fossas e de tanques sépticos
Septic tanks are small structures used for partial treatment of wastewater produced from urban and rural areas. It utilization is justify mainly by simplicity of construction and for being a technology that requires low operational dedication. Although it is a technology vastly used in Brazil, there is not much information about the characteristics of the wa

6. Avaliação da co-disposição do lodo de tanques sépticos e fração orgânica de resíduos sólidos domiciliares em reatores anaeróbios / Evaluation of co-disposal of sludge from septic tanks and organic fraction of domestic solid waste in anaerobic reactors
Despite being an emerging country, unfortunately the sanitary situation of Brazil is quite precarious. Only 52.2% of the 5,507 brazilian municipalities have some type of sanitary service (IBGE, 2000). In this alarming scenario, individual solutions are gaining more importance. The adoption of septic tanks as an alternative to the solution of the sewage becom

7. Environmental characterization of the Mogi Guaçu river upstream region (Bom Repouso - MG): replicability strategies and guidelines for drawing up the environmental adequation plan / Caracterização ambiental da região de montante do rio Mogi-Guaçu (Bom Repouso - MG): estratégias para replicabilidade e diretrizes para elaboração do plano de adequação ambiental
The upstream region of the river Mogi Guaçu is considered strategic regarding the water issue, with hundreds of springs that contribute to the formation of brooks and streams and which enable the multiple uses of water in cities located in the states of Minas Gerais and São Paulo. Considering this, we tried to carry out an environmental diagnostic (between

8. NUMERICAL MODELING OF VIRUS TRANSPORT IN FRACTURED-POROUS MEDIA / MODELAGEM NUMÉRICA DO TRANSPORTE DE VÍRUS EM AQÜÍFEROS FRATURADOS - POROSOS
Setback distances of wellhead and catchments from septic tanks are establised by three aproaches: methods based on fixed setback distances or fixed travel times; methods based on vulnerability analysis and methods based on infection risk. In Costa Rica, the determination of setback distances is based on fixed travel times. This approach considers that during

11. Schistosomiasis mansoni in Bananal (State of São Paulo, Brazil): IV. Study on the public awareness of its risks in the Palha District
A rather high prevalence of mansoni schistosomiasis has been observed in some localities of Bananal, State of São Paulo, during the past decade. The highest prevalence of schistosomiasis was found in the Palha District; it was thus considered adequate for an evaluation of public awareness of the risks involved in acquiring schistosomiasis, a likely outcome

12. Assessment of bifidobacteria as indicators of human fecal pollution.
The distribution of bifidobacteria in the environment has been examined by using YN-6 medium. Although feces of humans, chickens, cows, dogs, pigs, horses, cats, sheep, beavers, goats, and turkeys were examined, bifidobacteria were isolated only from the feces of humans and swine. The frequency and distribution of component species of human fecal isolates we
