Abstract
This audit presents a modification of the rinsing stages of the conventional chromium plating technology. After chromium plating the parts are rinsed. The first rinsing bath which is high in chromic acid, is recycled and the last cold rinsing bath is regenerated on ion-exchange resins and recycled. In the conventional process, the last cold rinsing bath is discarded.
