Previous issue date: 2017-04-20 / Esta??es de Tratamento de ?gua s?o concebidas em fun??o da qualidade da ?gua do manancial, o que determina diretamente a tecnologia de tratamento a ser utilizada e consequentemente influi nos custos de opera??o e manuten??o. A adequa??o dos processos dentro das ETA ? fundamental para diminui??o dos custos e melhoria na qualidade da ?gua tratada. O processo de filtra??o ? considerado pela literatura como etapa de polimento, respons?vel pela remo??o de part?culas em suspens?o, e remo??o de cistos e oocistos de protozo?rios. A retrolavagem dos filtros pode consumir entre 3% a 10% do volume produzido nas ETA, ou seja, ? relevante no resultado final de produ??o de ?gua. O objetivo geral desse trabalho foi avaliar as modifica??es na produ??o de ?gua na ETA em escala real atrav?s da altera??o nas carreiras de filtra??o. Foram realizadas caracteriza??o f?sica e qu?mica da ?gua de lavagem dos filtros, da ?gua bruta, da ?gua tratada e da ?gua de recircula??o, al?m do monitoramento do n?vel da ?gua dos filtros em carreiras de filtra??o diferentes. Os resultados demonstraram que com o aumento da carreira de filtra??o aumentou a quantidade de s?lidos na ALF; o crescimento do n?vel da ?gua se comporta como fun??o de primeiro grau; pode-se alterar a carreira de filtra??o de 24 horas para 40 horas em condi??es normais na ETA Extremoz. / Water treatment plants are designed according to the water quality on source, which directly sets up the treatment technology to be used and consequently influences costs of operation and maintenance. The adequacy of the processes in WTP is primordial for reducing costs and improving the quality of treated water. The filtration process is considered by the literature as polishing step, responsible for the removal of suspended particles, and removal of protozoan cysts and oocysts. During backwashing it may consume from 3% to 10% of volume produced in the WTP. It?s relevant in the final result of water production. The general objective of this paper was to evaluate modifications in production of water on WTP in real scale through changes in filtration?s careers. Physical and chemical characterization of backwashing?s water of the filters, raw water, treated water and recirculation?s water, as well as the monitoring of the pressure loss of the filters in different filter run. The results showed that: increasing in filter run increased the amount of solids in backwash water; the growth of the loss behaves as a first-degree function; You can change filter run from 24 hours to 40 hours under normal conditions at WTP Extremoz.
