Abstract
Heavy metal and oxidizable contaminants are removed from waste water by electrolysis to obtain metallic precipitation of the heavy metal on a stainless steel cathode while simultaneously other contaminants are oxidized on a lead oxide coated titanium or graphite anode; certain additives may be used to break up complex components; subsequently the partially decontaminated electrolyte is passed through an adsorber column for further removal of said contaminants.
