ABSTRACT:
Apparatus for elctrolytically removing silver from a spent photographic processing solution. A thin flexible cathode sheet is removably fitted within the inside periphery of a tank which receives the solution. A lid unit is removably secured over the tank and rotatably supports an anode assembly extending within the tank. A power unit is removably secured on the lid unit and carries a motor for driving the anode assembly to circulate the solution. An electric power conducting circuit in the power unit is automatically connected to the anode assembly and the cathode when the power unit is secured.
