Electroplating Tip Sheet: Rinse Water Reduction

WebElectrowinning is a term used to describe plating metal from a solution for recovery purposes. The water containing nickel is introduced to a plating cell with many anodes and cathodes. DC current and voltage is applied and nickel is deposited on the cathode. The cathodes may be stripped of nickel from time to time, and the nickel reused. WebThe waste containing heavy metallic ions such as nickel, chromium, zinc, lead, silver, cadmium, mercury, cyanides etc. are more hazardous. The hazardous waste generated … WebTarget Pollution Loads. A key parameter is the water use in each pro-cess. Systems should be designed to reduce wa-ter use.
