Electrodialysis Stacks for cost effective recovery and reuse of nickel electroplating solutions from Bright Nickel electroplating effluent are available. Electrodialysis is a clean technique able to produce dilute and concentrated solutions from a contaminated started solution.

The treated effluent had sufficient quality for reuse as rinsewater in galvanic process. All ions detected presented adequate concentrations for reuse. Even the organic compounds from the additives could be removed by ED.

Electrodialysis can be applied effectively for chromium recovery from chromium electroplating drag-out for reuse. Electrodialysis effectively recovers more than 80 percent of plating metals such as nickel, chromium, cadmium, copper and zinc.

Recovery of EDTA from electroless copper plating bath.

Recovery of exhausted alkali from process solutions for the manufacture of nickel-cadmium batteries.
