Abstract

"PROCESSO QUE PERMITE EVITAR OU REDUZIR A OBSTRUçãO DE MEMBRANAS DE FILTRAçãO". Processo que permite evitar ou reduzir a obstrução das membranas de filtração empregadas notadamente no tratamento de efluentes tais como águas servidas caracterizado pelo fato de que ele consiste em adicionar ao efluente a filtrar, um adsorvente orgânico natural destinado a captar as moléculas e partículas obstrutivas em face das membranas de filtração.
