ABSTRACT:
A system and apparatus for dewatering a suspension of solids in a carrier liquid by means of an electrically augmented vacuum filter (EAVF). The EAVF including an anodic structure comprising an anode, anolyte and a filter membrane for depositing solids from the suspension of solids thereon; 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.
