Acid Recycling Technology

Abstract

Wastes from plating and other wet processing operations are a permanent liability for the generator. With the Resources Conservation and RecoveryAct (RCRA) and other legislation, the legal, financial and moral obligations imposed on waste generators have become major area of concern. Recovering acids from process waste avoids the costly problems of treatment, disposal, reporting and liability. Cleaner process baths improve manufacturing quality and maximize production capacity. This fact sheet describes the use of diffusion dialysis, a membrane separation technology designed for the metal finishing industry to recover acids from process baths.
