Abstract

"PROCESSO PARA TRATAMENTO FìSICO-QUìMICO DE EFLUENTES". Processo de tratamento físico-químico de efluentes, especialmente de águas de superfície destinadas ao consumo que compreende as etapas sucessivas de coagulação (A), de floculação (B) e de decantação (C), sendo introduzida uma massa de contato na água proveniente da etapa de coagulação, portanto durante a etapa de floculação e esta massa de contato sendo constituída por uma parte das lamas densificadas proveniente da etapa de decantação e reciclada para a etapa de floculação, este processo sendo caracterizado pelo fato de que se injeta, no circuito de recirculação das lamas (16) pelo menos uma parte do polieletrólito que garante a floculação.
