Zero Discharge Spray Rinse System for Electroplating Operations.

Abstract

The zero discharge spray system comprises a tank for collecting and storing rinse water, a set of spray nozzles aligned within the tank, and a pump for both pumping used rinse water through the spray nozzles and/or to the plating bath as makeup for evaporation. A timer level control system maintains the plating bath level and the rinse tank level, and limits the nozzles spray time. The system also includes a fresh water spray for final rinse of plated parts. By using a controlled spray rinse system which reduces the amount of water added to the system so as not to exceed that lost by evaporation, no contaminated rinse water is discharged as waste. Patent Application. (mjm)
