ABSTRACT:
Closed recycle system for chromium plating solution, solution wastes from chromium plating and chromic acid cleaning water in chromium plating composed of a chromium plating chamber including a chromic acid mist recovery device in communication with a recovery vessel for recovering and liquefying chromic acid mists formed upon chromium plating, and a chromic acid mist cleaning tower in communication with the recovery vessel for cleaning chromic acid mists flowing from the chromic acid mist recovery device. The recovery vessel is preferably positioned underground, and also preferably positioned in the recovery vessel. Liquid wastes containing noxious substances formed in chromium plating factories are utilized, and generation of materials leading to public pollution is prevented.
