1. Uso da Luffa cylindrica como meio suporte para crescimento bacteriano em filtro anaeróbio tratando esgotos domésticos
O afastamento em relação aos centros urbanos, em geral, é o maior responsável por inviabilizar economicamente a implantação de uma rede coletora de esgoto nas comunidades periurbanas. Sistemas simplificados e de alta relação benefício/custo podem se mostrar bastante vantajosos como solução sanitária. No Brasil, o filtro anaeróbio tem sido freque

2. Start-up and steady-state conditions of an Anaerobic Hybrid Reactor (AHR) using mini-filters composed with two types of support medium operating under low loading rates
The present work aimed at studying the operational parameters of an Anaerobic Hybrid Reactor (AHR) removing organic matter of coffee wastewater with low concentration. The AHR was built similar to an UASB reactor, however the interior was filled with mini-filters composed by two types of support materials: expanded clay and rolled pebble. Three start-ups wer

3. Tratamento de efluente anaeróbio : condicionamento em filtro de areia visando lançamento e reúso / Anaerobic effluent treatment : sand filters conditioning to disposal or reuse applications
Increasing scarcity of freshwater due to demographic growing, urbanization and, climate changing are the reason of increasing use of the wastewater in agriculture. Nowadays, this practice is a reality, mainly in São Paulo in the southeast areas, where the conflicts caused by multiples use of water are constant. Based on this situation, the aiming of this in

4. 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

5. Tratamento de esgoto sanitario em reator anaerobio preenchido por casca de coco verde (Cocos nucifera) combinado com filtro de areia / Wastewater treatment through an anaeroboc filter filled up with coco nuts (cocos nucifera) combined with sand filter
The development of efficient wastewater treatment systems, which are also adapted to the economic and structural conditions of a village, would be an option to decrease the lack of water problem since the effluent could be reused or discharged into receiving waters. Moreover, with wastewater system, health and environmental problems would be less frequent. F

6. Desempenho de wetlands construídas (banhados construídos) no tratamento de manipueira
The objective of this research was to assess the possibility of applying subsuperficial flow constructed wetlands to lower the pollution load from cassava processing wastewater (cassava wastewater) and to produce Green biomass. The study was performed at lab-scale by using 4 glass units, with fine sand as substrate, where 3 units were cultivated with Tangola

7. Tratamento de lixiviado de aterro sanitário por um sistema composto por filtros anaeróbios seguidos de banhados construídos: estudo de caso - Central de Resíduos do Recreio, em Minas do Leão/RS / Sanitary landfill leachate treatment for a system composed by upflow anaerobic filters followed by constructed wetlands: case study - Recreio Central Waste, in Minas do Leão/RS
This study discussed the sanitary landfill leachate treatment in a full scale system composed by two upflow anaerobic filters followed by two constructed wetlands. The research was developed at the landfill leachate treatment station owned by Recreio Central Waste, located in Minas do Leão/RS. The objective of the study was to verify the efficiency of the s

8. AVALIAÇÃO DA INFLUÊNCIA DO MATERIAL SUPORTE E CARACTERIZAÇÃO DA DIVERSIDADE MICROBIANA DE REATORES ANAERÓBIOS PARA O TRATAMENTO DE EFLUENTE DE ABATEDOURO
The effluent generated in abattoirs has a high concentration of organic matter and need treatment before being discarded in the water bodies. Anaerobic biological filters are considered a good technique for the treatment of industrial effluents; however, choosing the correct support media is extremely important to ensure the success of the reactor. In the sa

9. Produção de forragem verde em sistema hidropônico usando esgoto tratado
In the urban areas of the cities a larger problem of destiny of effluents of the treatment stations is verified due to the junction of the sewages in great volumes. This way the hidroponic cultive becomes important, for your intensive characteristic, as alternative of reuse. This work presents as objective the improvement of the relation hidric-nutritious of

10. Avaliação da eficiência de filtros anaeróbios na remoção de coliformes fecais e ovos de helmintos
The technology of anaerobic reactors for sanitary wastewater treatment has been extensively developed in Brazil, and today it is practically consolidated. They present several advantages, such as low construction and operating costs, and low sludge production, the anaerobic reactors are an attractive alternative to minimize problematic lack of basic sanitati

11. Análise de perigos e pontos críticos de controle APPCC: estudo de caso no sistema de abastecimento de água da Universidade Federal de Viçosa / Hazard Analysis and Critical Control Points HACCP: study of the case in treatment plan of water at Universidade Federal de Viçosa
The drink water production to human use with adequate standards is very important to the health of consumers. At present, there are many researches in development to value the treatment of water in the world with support of World Health Organization and Health Treasury. On this context, the HACCP system is a important instrument to maintain the quality in wa

12. Nitrificação de efluente de reator anaeróbio compartimentado em filtros percoladores com a utilização da serragem de couro do tipo wet blue como meio suporte / Nitrification of anaerobic baffed reactor effluent into trickling filters using wet blue leather sawing as a filter packing
The aim of the work is to promote the ammoniacal nitrogen removal from anaerobic baffed reactor effluent using aerobic trickling filters, through the nitrification process. The research was developed in two phases; firstly the leather sawing was prepared through sieving and washing, later the domestic sewage was applied into four tricking filters. The F1 and
