Closed-Loop Hexchrome Plating Waste Recovery Process (280)

The University of Dayton Research Institute has developed and demonstrated a recovery process for toxic hexavalent chromium from hard and decorative chrome plating baths.  This easy-to-implement process involves precipitation of the chrome in the hexavalent oxidation state, unlike current treatment practices which involve chemical reduction.  Because the recovered chromium is in the hexavalent oxidation state, recovery and reuse involves simple resolubilization, with minor addition of virgin chromium to bring the plating solution back up to designated standards.
