Abstract

Patente de Invenção: "PROCESSO PARA FLOCULAR SUSPENSõES". Um processo para a floculação e a remoção de água de uma suspensão aquosa de sólidos em suspensão que compreende a introdução dentro da suspensão de (a) uma solução concentrada de polímero, e (b) uma solução diluída de polímero, caracterizado pelo fato de que as soluções concentrada e diluída de polímero são introduzidas dentro do substrato de forma substancialmente simultânea. De preferência as soluções de polímero concentrada e diluída são introduzidas no interior da suspensão como uma composição aquosa que compreende uma solução aquosa diluída do polímero e uma solução concentrada do polímero. O processo apresenta aperfeiçoamentos na filtragem e em tortas de sólidos.
