1. Remoção de algas em um sistema de biofiltros submersos
RESUMO Esta pesquisa propôs o desenvolvimento de um sistema de biofiltros submersos (SBS), modificados com base na configuração de filtros de pedra, visando ao pós-tratamento do efluente de lagoas de estabilização, inicialmente para a remoção de algas. Foram implantados 2 conjuntos de biofiltros submersos para captar esgoto tratado de duas diferentes

2. Biossorção de íons Cr(III) de soluções aquosas sintéticas e efluente de curtume utilizando a macrófita aquática Pistia stratiotes
RESUMO O cromo é um metal tóxico amplamente utilizado em processos industriais, por isso a constante preocupação com os efluentes líquidos gerados. Uma vez lançados sem o devido tratamento podem comprometer a qualidade do corpo receptor. Este trabalho teve por objetivo analisar o processo de biossorção na remoção de íons Cr(III) de soluções aquo

3. Efeito da qualidade da água no ciclo de vida e na atração para oviposição de Aedes aegypti (L.) (Diptera: Culicidae)
The present research aimed at evaluating the influence of the water quality in the life cycle and attraction of Aedes aegypti (L.) females to oviposit using different sources of water (raw sewage, effluent of UASB reactor, effluent of polishing lagoon, effluent of anaerobic filter, rain water and de-chlorinated water). The immature development time and survi

4. Avaliação (em escala laboratorial) da aplicação do processo eletrolítico em efluente de lagoa de estabilização de esgoto urbano
Physico-chemical and microbiological parameters were evaluated before and after applying an electrolytic process to effluents of a stabilization lagoon, in the presence or absence of "salt". Chlorine generation and bactericidal properties of the treatments were studied following two experiments. Effluent pH increased with electrolysis time. In the absence of

5. Evaluation of HA negatively charged membranes in the recovery of human adenoviruses and hepatitis A virus in different water matrices
Human adenoviruses (HAdV) and hepatitis A virus (HAV) are shed in the faeces and consequently may be present in environmental waters, resulting in an increase in pathogen concentration that can affect water quality and human health. The aim of this study was to evaluate an adsorption-elution method which utilizes negatively charged membrane HA to determine t

6. Tratamento físico-químico de lixiviado de aterro sanitário pré-tratado por processo biológico aeróbio. / Physico-chemical treatment of landfill leachate from pre-treated by aerobic biological process.
Landfill leachates present high ammonia and organic matter concentrations, besides other pollutants, which do not allow its discharge to the environment without a previous treatment. Older landfill leachates, with more stabilized organic matter, present great pollutant potential, mainly due to the presence of recalcitrant substances that not often are remove

7. Avaliação da produção de odor na estação de tratamento de esgoto Paranoá e seus problemas associados
The Federal District of Brazil has been suffering problems of emanations of odors proceeding from sewage treatment plants (STP). For this reason, this work has the objective of evaluating the production of odor in the Paranoá sewage treatment plant (Paranoá STP), in Federal District, and its associated problems, employing hydrogen sulfide (H2S) as an indic

8. O impacto de uma lagoa receptora de efluentes industriais contendo boro em um aqüífero raso / Groundwater impact caused by an industrial effluente lagoon with boron
The boron (B) occurs naturally at low concentrations in surface and ground waters used to human supply and irrigation. Although concentration >1mg/L can cause health and environmental problems, detailed studies on transport and fate of B in aquifers are restricted in Brazil. This study investigated the impacts on groundwater quality caused by an industrial (

9. Avaliação da qualidade dos efluentes das lagoas de estabilização em série da estação de tratamento de esgoto de Samanbaia - DF: para o cultivo de tilápia (Oreochromis niloticus) / Evaluation of the quality effluent from Samambaia (DF) wastewater plant serial stabilization lagoon for tilapia (Oreochromis niloticus) cultivation
O enfoque principal desta pesquisa é a utilização de águas residuárias tratadas da ETE-Samambaia para criação de peixes. Objetivou-se avaliar se a qualidade do efluente da estação é apropriada para a criação da espécie tilápia do Nilo (Oreochromis niloticus) e, em caso negativo, que soluções podem ser dadas para a situação. O trabalho foi d

10. Irrigação por infiltração com efluente de lagoa anaerobia em solo cultivado com milho (Zea mays L.)
The experiment was conducted around of a Sewage Treatment Plant located in Limeira city, São Paulo, Brazil. This research had the proposal to reuse the domestic effluent treated in an anaerobic lagoon, that present a BOD removal efficiency of 50%. The main objective was the determination of application rates of effluent in the soil according to sanitary and

11. Distribution and survival of motile Aeromonas spp. in brackish water receiving sewage treatment effluent.
The spatiotemporal distributions of Aeromonas spp. and fecal coliforms in a cove receiving sewage treatment effluent and draining into a brackish lagoon were studied for 34 months with sampling at six stations. A total of 452 strains of Aeromonas spp. were isolated and identified at the outflow of the treatment system and at stations in the cove. Hemolytic a

12. Bacterial Diversity and Community Structure in an Aerated Lagoon Revealed by Ribosomal Intergenic Spacer Analyses and 16S Ribosomal DNA Sequencing
We investigated the bacterial community structure in an aerated plug-flow lagoon treating pulp and paper mill effluent. For this investigation, we developed a composite method based on analyses of PCR amplicons containing the ribosomal intergenic spacer (RIS) and its flanking partial 16S rRNA gene. Community percent similarity was determined on the basis of
