In-Process Recycling of Spent Hexavalent Chromium Plating Bath

EPA Contract Number: 68D98140
Title: In-Process Recycling of Spent Hexavalent Chromium Plating Bath
Investigators: Renz, Robert P.

EPA Contact: Manager, SBIR Program
Phase: I
Project Period: September 1, 1998 through March 1, 1999

Research Category: Pollution Prevention/Sustainable Development , SBIR - Pollution Prevention

Description:

This SBIR project involves the development of a novel in-process recycling process to decontaminate a spent hexavalent chromium plating bath and eliminate the hazardous waste associated with chromium plating operations. Hexavalent chromium plating will continue due to unique performance characteristics. The toxic mist associated with hard chrome plating processes can be contained; therefore, the only remaining issue is to develop a technology to cost-effectively decontaminate a spent hexavalent chromium plating bath. The proposed novel in-process recycling process will integrate electrodialysis and ion-exchange into one system to simultaneously remove all the contaminants from the spent chromium plating bath. The process makes in-process recycling of a spent chromium plating bath possible and will save millions of dollars in both material costs through recycling and the costs of sludge disposal in a hazardous waste landfill.
