A chromium regeneration apparatus (10) is disclosed for regenerating spent chromium solution by oxidizing trivalent chromium to hexavalent chromium. The apparatus is provided with a tank (42) forming a reservoir full of spent chromium solution. A number of anode assembles (46) are supported on the tank within the reservoir with each assembly including two frame sections (70, 72) bolted together along their sides and bottom with two separate cation selective membranes (100, 102) secured therebetween. Membrane tensioners (104) are inserted between the membranes to separate them and urge them against the frame sections over openings in the frame sections to define an anode chamber. An anode and cathode are provided to a generate a current flow therebetween to regenerate the solution.
