发明名称 Electrically augmented vacuum filtration
摘要 A process for dewatering a suspension of solids in an electric field controllably maintained between opposing electrode structures, causing the solids to migrate relative to the carrier liquid to form a layer or cake on one set of electrode structures while withdrawing carrier liquid under vacuum in the opposite direction through the liqid pervious wall of hollow, counterelectrode structures. A selected electrolyte is pumped through the hollow electrode structure on which the cake is formed to continuously bathe the electrode element therein in said electrolyte. Vacuum is applied to the electrolyte in said electrode structure to remove gases evolved at the electrode element. The cake material is detached from the electrode structure and recovered.
