An apparatus for the electrolytic regeneration of hexavalent chromium compounds and recovery of metals from waste bichromate solutions comprises a tank, a plurality of semipermeable membranes subdividing such tank into a plurality of compartments, cathode and anode electrodes positioned in alternate compartments of the tank to form a series of cathodic and anodic compartments and means for circulating the waste bichromate solution through the anodic compartments to oxidize the chromium compound to its hexavalent form, and at least part of the waste bichromate solution through the cathodic compartments for electrodeposition of metals on the cathode. |
