Abstract
A system and method for dewatering of a suspension of solids in an electric field controllably maintained between a pair of opposing self-contained electrode structures, to cause the solids to migrate relative to the carrier liquid to form a layer or cake on the respective self-contained electrode structure, while allowing carrier liquid to be withdrawn under vacuum in the opposite direction through the liquid - pervious wall of a hollow self-contained counter electrode structure, combined with means for controlling the rate of filtrate liquid withdrawal consistent and compatible with the relative speed of migration of the solids in the carrier liquid, and wherein said layer or cake material may be detached from said electrode structure, for instance during exposure from the suspension.
