Title: Apparatus and method for removal of soluble metal ions from aqueous effluent

Abstract: Apparatus for removal of soluble metal ions, preferably copper ions, from an effluent solution is provided comprising a chamber for continuous passage of effluent therethrough having high surface area donor and acceptor electrodes in physical contact provided therein. One preferred embodiment comprises a rectangular tank having a multiplicity of high surface area stainless steel and aluminum electrode members comprising screens or expanded or perforated sheets bisecting the flow of effluent therethrough and being in physical contact. An alternate embodiment comprises a cylindrical tank having a "jelly-roll" configuration of stainless steel and alumium screens in physical contact provided in the center of the tank, along its longitudinal axis. A method for removal of soluble metal ions from effluent solution is provided comprising treatment of the effluent by passage through the apparatus of the invention.
