Abstract

A process for removing contaminants from large volumes of wastewater is disclosed. The process involves treating a wastewater stream containing the contaminant with a coagulant that reacts with the contaminant to form a particulate or aggregate of particulates having a size greater than 10 &mgr;m. The treated wastewater is passed through a microfiltration membrane having a pore size in the range from 0.5 &mgr;m to 10 &mgr;m at low pressure (less than 20 psig) to remove the contaminant. Under such conditions, the treated wastewater flux rate is greater than 200 gallons per square foot of membrane per day (“GFD”), and typically from 200 to 1500 GFD.
