Ozone Oxidation of Metal Plating Cyanide Wastewater.
Abstract
Electroplating facilities, as associated with aircraft engine maintenance bases operated by the Air Force, generate quantities of wastewater contaminated with cyanides. Although traditionally treated with chlorine, a process was developed by the Houston Research Corporation under Contract No. F29601-72-C-0065 using ozone to oxidize the cyanides. A demonstration plant was designed by CPAC and installed at Tinker Air Force Base to treat 3000 gallons per month of primarily nickel strip waste at concentration up to 50,000 mg/1 of total cyanide. A series of test runs proved ozone to be very effective and economically competitive for the destruction of simple cyanides and most metal complexes. The iron complex proved to be very difficult to destroy even in the presence of UV light and elevated (150 F) temperature. (Author)
