26. Sistema fermentativo de duas fases para a produção de hidrogênio e metano a partir de esgoto sanitário combinado com águas residuárias industriais / Two phase fermentative for hydrogen and methane production from domestic wastewater combined with industrial wastewaters
A possibilidade da produção de hidrogênio a partir de esgoto sanitário com a posterior geração de metano a partir do efluente do processo acidogênico foi avaliada em reatores anaeróbios em batelada e contínuos. Nos reatores em batelada com biomassa acidogênica não houve produção de hidrogênio a partir de esgoto sanitário, o que motivou a avali

27. Remoção de matéria orgânica carbonácea e nitrogênio em Reator Aeróbio-Anóxico de Leito Fixo (RAALF) aplicado ao pós-tratamento de efluente de reator anaeróbio / Removal of carbonaceous organic matter and nitrogen in an Aerobic-Anoxic Fix Bed Reactor (AAFBR) applied to the tertiary treatment of domestic wastewater
This work presents the Aerobic-Anoxic Fix Bed Reactor (AAFBR), with superimposed chambers, as an alternative concerning the post-treatment of anaerobic reactors efiluents aiming the removal of carbonaceous organic matter and nitrogen. Polyurethane foam cubic matrices (5 mm) were used packing material. Hydrodynamic essays were carried out in order to obtain t

28. 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

29. AvaliaÃÃo da Piscicultura em Esgoto DomÃstico Tratado: Aspectos ZootÃcnicos, Ambientais e de Qualidade do Pescado Produzido / Evaluation of treated domestic sewage in fish: aspects of husbandry, environmental and quality of fish produced.
The use of wastewater is an alternative widespread nowadays. One way to reuse it in fish activity, considering that the effluent from Sewage Treatment Stations, are rich sources of nutrients that could be used by fish. However, some restrictions arise regarding the quality of animals for use in human diet. Thus, this research was conducted using treated sewa

31. Avaliação do perfil de resistência a antimicrobianos de bactérias gram-negativas isoladas nas águas do Arroio Dilúvio / Evaluation of antimicrobial resistance the profile of gram-negative bacteria isolated from dilúvio gully waters
The Dilúvio is part of an important watershed in the city of Porto Alegre, RS, having 17.605m of extension rising in the city of Viamão and flowing into Guaíba Lake receiving all kind of waste resulting from pluvial, domestic and hospital wastewater. Thus, the gully receives a diverse microbial population, some of these microorganisms may exhibit resistan

32. Tratamento combinado de drenagem ácida de minas e esgoto doméstico
Muitos locais de mineração de carvão estão próximos a centros urbanos, coexistindo, nestas regiões, a drenagem ácida de minas (DAM) e os esgotos domésticos, sendo que, ambos os efluentes afetam a qualidade da água dos corpos receptores se ali lançados sem o devido tratamento. A drenagem ácida de minas afeta a qualidade da água baixando o pH, aume

34. Estrogênios em águas naturais e tratadas da região de Jaboticabal - São Paulo
The aim of this work was to analyze 17 β estradiol and estrone, natural estrogenic hormones present in domestic effluents and animal excreta, in the public water supply system of Jaboticabal, SP. The results have shown the presence of estrogens in 22% of the samples in concentrations from 6,8 ng L-1 (treated water) to 30,6 ng L-1 (riverhead) for 17 β estra

In the present work was estimated the contribution of methane emission to the global atmosphere. In this study were realized two campaigns of collections in the settling ponds n.°03 (2008) and n.°04 (2010) with sampling operation being carried out in points coming into and out of the lagoons. A gas collector has been utilized as the UASB inner gas keeper a

36. Avaliação da utilização de colifagos como indicadores virais a partir da análise de enterovírus e adenovírus em efluentes tratados por diferentes processos biológicos
Domestic sewage contains a high amount of bacteria and other pathogens and non pathogens that are discharged into water bodies. Contamination of water by the presence of pathogenic bacteria and viruses, brings undesirable consequences, especially for public health.
