Abstract

trata-se de um sistema para tratar água servida que compreende uma montagem de coagulação-floculação que tem uma entrada de água servida bruta e uma saída de água servida coagulada-floculada; e um separador de pasta fluida que compreende uma área de ingresso configurada para receber pasta fluida de água servida da saída de água servida coagulada-floculada, uma saída de líquido, uma saída de sedimentos e um módulo de filtração configurado para facilitar a penetração de líquido através do mesmo e a formação de um bolo de filtração no mesmo. em que o separador de pasta fluida é configurado para receber pasta fluida na área de ingresso, separar a pasta fluida em líquido e sedimentos através do módulo de filtração, remover o líquido por meio da saída de líquido e transportar os sedimentos da área de ingresso para a saída de sedimentos. o sistema compreende adicionalmente uma disposição de manutenção de nível configurada para manter pelo menos um nível mínimo do bolo de filtração.
