13. Tratamento e reuso do efluente de biodigestores no processo de biodigestão anaeróbia da cama de frango / Treatment and reuse of efluent of digesters in the anaerobic digestion of poultry litter
The anaerobic digestion process contributes as a method of treating poultry litter and energy generation. However, its applicability may cause some counter-intuitive, requiring for dilution to provide a suitable environment for microorganisms active in the anaerobic process. This dilution increases volume and difficulty of disposal of effluent. Thus, the obj

15. Comportamento hidrodinâmico e cinético dos reatores anaeróbios compartimentado (RAC) e manta de lodo (UASB) operados em série / The hydrodynamic and kinetic bahavior of the anaerobic baffled reactor (ABR) and upflow anaerobic Sludge blanket (UASB) operated in serie
The aim of this research was to determine the hidrodymanic and kinetics behavior of a pilot system plant, treating swine liquid effluent, installed in the Zootechnical Department of the Federal University of Lavras. The pilot system was composed by several units working in series, such as sand retention box (SRB), static sieve (SS), acidification and equaliz

16. 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

17. Reúso de efluente de esgoto sanitário anaeróbio e nitrificado em irrigação de roseiras / Reuse of anaerobic and nitrified wastewater effluents for irrigation of roses
Wastewater secondary treatment plants effluent may contain, yet, nutrients in amounts harmful to the environment. These effluents discharging can cause eutrophication in receiving waters, making it unsuitable for intended uses, such as provision for human consumption, leisure activities, etc. Besides the problem of eutrophication, there is the difficulty to

18. Tratamento de água para consumo humano de reservatório eutrofizado através de pré e interoxidação, adsorção em carvão ativado e dupla filtração / Drinking water treatment of eutrophic reservoir by pre and interoxidation, activated carbon adsorption and double filtration
Disordered basins occupation provoked acceleration of eutrophication, which besides purely aesthetic and landscaping problems, results in occurrence of high phytoplankton densities with potentially toxic cyanobacteria dominance. Alongside physical aging and consequent deterioration of installations, usual treatment technologies do not provide adequate condit

19. Estudo comparativo da sensibilidade de dois organismos expostos a efluentes líquidos. / Comparative study of the sensitivity of two organisms exposed to effluents
Given the multiplicity of actions caused by the interaction of chemical agents with possible damage to biota by effluent, the most effective strategy is the integrated use of physical, chemical and ecotóxicological assessment and forecast of environmental risk. In this sense, ecotóxicological tests are important means of environmental monitoring in order t

20. Effluent generation index applied to oil refinery / Índice de geração de efluentes aplicado a uma refinaria de petróleo
Visando subsidiar a gestão ambiental das indústrias do estado de São Paulo, aperfeiçoar o planejamento e execução de suas ações, a Companhia Ambiental do Estado de São Paulo CETESB instituiu o monitoramento por indicadores ambientais envolvendo a captação de água, a geração e lançamento de efluentes versus produto principal produzido. Atendend

21. Variabilidade interanual (10 anos) da comunidade zooplanctônica na região costeira do Espírito Santo, em área sob influência de efluente industrial aquecido
In the last decade (1998-2007) collections were made of biotic (zooplankton) and abiotic (temperature and salinity) in the coastal waters adjacent to Praia Mole, in the Espírito Santo, in order to monitor the potential effects of disposal a heated effluent on the zooplankton community. This study aimed to analyze the data generated by this monitoring by obs

22. Partially aerated attached biomass bed reactor applied to treatment sanitary sewage treatment / Reator com leito de biomassa aderida aerado parcialmente aplicado ao tratamento de esgoto sanitário
This work aimed to evaluate the performance of a full scale up-flow attached biomass bed reactor (159 M POT.3) and with continuous aeration at 7 m above bottom of the reactor to sanitary sewage treatment. The bed of the reactor was constituted for activated granular carbon, anthracite carbon and sand. The work was divided into two stages. In the first stage,

23. Lamella sedimentation: alternative for treatment of overflow sewage - study in ETE Martim de Sá (Caraguatatuba/SP). / Decantação acelerada: alternativa para o tratamento de vazão excedente de esgoto - estudo na ETE Martim de Sá (Caraguatatuba/SP).
This study was motivated by the need to treat high wastewater influent exceeding in sewage treatment plants, which occurs on days of heavy rain. The central hypothesis of this study is that the physical-chemical process to treat dilute sewage overflow, it can be advantageous with respect to increased capacity and expansion of biological systems. The research

24. 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. The objective of this work was to evaluate the possibility of using analysis of coliphages as
