Abstract
Wastewater from metal plating operations is treated to remove heavy metal and other contaminants, including toxic organic materials, chelating agents, and cyanide. The wastewater is passed through the cathode and anode of an electrochemical reactor in which the cathode preferably comprises a felt mass of conductive fibers and the anode comprises porous carbon, carbon fibers or metal oxides. A method and apparatus are disclosed which are particularly useful in removing impurities from plating plant wastewater.
