  • Patent number: 4689134
    Abstract: A system and apparatus for dewatering a suspension of solids in a carrier liquid by means of an electrically augmented vacuum filter having an anodic electrode structure comprising an anode and a liquid impervious wall, wherein the wall is a non ion selective membrane which is permeable to both cations and anions. The non ion selective membrane being impervious to the suspension solids, carrier liquid, electrolyte and gaseous electrode reaction products. This non ion selective membrane comprises a substrate and a solid polymeric film, wherein the substrate is a cloth support and the solid polymeric film comprises a cation exchange resin, an anion exchange resin and a binder. The charge transfer numbers of the non ion selective membrane t.sup.+ is in the range of 0.20 to 0.80 and t.sup.- in the range of 0.80 to 0.20, respectively.
    Type: Grant
