Abstract : Aqueous cyanide and complexed metal cyanide wastes from the Air Force's routine electroplating operations and color photographic film processing require extensive treatment to satisfy stringent water quality standards. A process was developed by laboratory experimentation using ozone for the total destruction of cyanide and metal cyanide complexes. Mass transfer and kinetic rate constants were determined by experimentation. A pilot scale prototype was designed, fabricated, and operated to destroy actual Air Force cyanide wastes. In all cases, cyanide concentration in the effluent was reduced to below the detectable limit. A conceptual design of a full scale system to treat electroplating waste is included.
