ABSTRACT:
A membrane for dewatering a suspension of solids in a carrier liquid by means of either an electrically augmented vacuum filter (EAVF) or an electrically augmented crossflow device. The EAVF and crossflow devices both include an anodic structure comprising an anode, anolyte and a filter membrane for depositing or concentrating solids from the suspension of solids; and a cathodic structure comprising a cathode, catholyte, a catholyte chamber, and a filtrate chamber for filtering the filtrate of the bath of the suspension of solids. The catholyte chamber having a membrane wall which is liquid impervious and either an anion exchange membrane or a non ion selective membrane. Filtrate being removed at the filtrate chamber.
