Abstract
The continuous flow of fresh water to and metal hydroxide contaminated water from a counter flow rinse tank in an electroplating apparatus is greatly reduced or eliminated by a parallel flow path provided to an adjacent ion exchange treatment unit and from the ion exchange unit back to the rinse tank. The rinse tank is fitted with a submerged pump to provide the rinse water to the ion exchange unit and through this unit back to the rinse tank.
