1. Desempenho da Tecnologia de Filtração em Múltiplas Etapas (FiME) no Tratamento de Águas de Abastecimento em Escala Piloto / Performance technology Multi-Stage Filtration (MSF) for supplying water treatment on a pilot scale
O presente trabalho avaliou a eficiência de um sistema de FiME no tratamento de águas de abastecimento em escala piloto. A instalação piloto FiME, localizada na área da Estação de Tratamento de Água (ETA) de Goianápolis, GO e alimentada pelo Ribeirão Sozinha, era composta de um pré-filtro dinâmico (PFD), um pré-filtro com escoamento vertical asc

2. Desempenho da Tecnologia de Filtração em Múltiplas Etapas (FiME) no Tratamento de Águas de Abastecimento em Escala Piloto / Performance technology Multi-Stage Filtration (MSF) for supplying water treatment on a pilot scale
The present work has evaluated the efficiency of an MSF system for treating supplying water on a pilot scale. A MSF pilot plant was located in the Water Treatment Station (WTS) area in Goianápolis- GO and fed by Sozinha stream. The plant was comprised of a dynamic prefilter (DPF) and a vertical upflowing pre-filter (VUF) in layers, both of them with differe

3. Filtração lenta em areia, manta não tecida e carvão ativado como pós-tratamento de efluentes domesticos e reuso / Slow sand filtration with non woven syxthetic fabric and activated carbon as after treatment of domestic sewer effluent and reuse
The slow sand filtration is a viable economic alternative for small communities moved away from the great urban centers. This work evaluated the efficiency of a slow filter with sand layer, activated carbon and non-woven synthetic fabric, compared with a slow filter of sand and non-woven synthetic fabric to treat constructed wetland effluent. The results had

4. Modelling and simulation of the biological and physical processes of slow sand filtration
Slow sand filtration (SSF) is the earliest form of engineered potable water treatment and remains one of the most efficient processes for improving the physical, biological and chemical quality of water. However, whilst widely used throughout the world, knowledge of the filtration mechanisms remains limited. This is important in understanding and managing th

5. Influencia da redução da espessura da camada suporte na eficiencia da filtração lenta com uso de mantas sinteticas não tecidas para aguas de abastecimento
The purpose of this study was to investigate the influence of the gravel suporter bed replacement for nonwoven synthetic fabrics in slow sand filtration for treating water supplies. The experimental investigation was carried out in a pilot plant built with an upflow roughing filter unit and three slow sand filtration units, which were made by sand (Te = 0,25

6. Reovirus removal and inactivation by slow-rate sand filtration.
Laboratory column studies were conducted at the Utah Water Research Laboratory, Logan, Utah, to evaluate reovirus removal from drinking water supplies by slow-rate sand filtration (SSF). Columns, constructed to simulate a full-scale SSF field operation, were inoculated with reovirus at ca. 1,000-times-greater concentrations than those typically found in dome
