Acid baths at the US Air Force/Oklahoma City Air Logistic Center (OC-ALC) will be rejuvenated by the use of a new technology -- Waste Acid Detoxification and Reclamation (WADR), a distillation process that concentrates the metals and creates a clean reusable acid. The concentrated metals are recovered for disposal or recycling. A 200-gallon batch prototype system will be installed and demonstrated on HCl, HNO{sub 3} and H{sub 2}SO{sub 4} baths at OC-ALC`s electroplating shop in late 1994. The system was tested in the summer of 1994 with typical industrial spent acids. The WADR system is expected to reduce waste from the OC-ALC acid baths by 80% to 90% as compared with current treatment operations. Laboratory test results and the prototype system design are presented here. The technology is expected to meet the needs of various industries generating spent acids with increasing disposal costs.
