Abstract

TRATAMENTO DE SUSPENSÕES AQUOSAS. Um processo em que uma suspensão compreendendo um material particulado disperso em um meio aquoso é transferida como um fluido para uma área de deposição, depois deixada repousar e enrijecer, e em que a rigidez é melhorada enquanto retém a fluidez da suspensão durante a transferência, mediante a combinação com a suspensão durante a transferência de uma quantidade de enrijecimento de um sistema de tratamento que compreende i) um polímero sintético solúvel em água e ii) um polímero natural ou seminatural solúvel em água. A rigidez melhorada pode ser obtida, incluindo a eficiência de dose especialmente quanto à quantidade de polímero sintético requerido. Além disso, melhoras na limpidez da substância líquida liberada a partir da suspensão podem ser alcançadas.
