Abstract
This disclosure is directed to a membrane or diaphragm-free, electrolytic process for removal of a significant portion of at least one metal contaminant from waste water containing it comprising contacting said waste water with a plurality of anodes, each anode having openings to permit the flow of waste water therethrough, and a plurality of metallized organic polymer foam reticulate cathodes wherein said anodes and reticulate cathodes are arranged in alternating manner and electrically energized.
Claims11
An electrolytic process for removing a significant portion of at least one metal contaminant from waste water comprising electrolyzing said waste water between a plurality of electrically energized anodes and cathodes arranged in an alternating sequence without either membrane or diaphragm separators therebetween, each of said anodes having openings therein permitting passage of such waste water therethrough and each of said cathodes being in the form of metallized organic polymer foam reticulates.
An electrolytic process for removing a significant portion of at least one metal contaminant while concurrently eliminating some cyanide contained in waste water comprising electrolyzing said waste water by circulating same through a plurality of electrically energized anodes and cathodes arranged in an alternating sequence without either membrane or diaphragm separators therebetween, each of said anodes and cathodes being formed of metallized organic polymer foam reticulates.
