Electrodialysis (ED) is, at present, used mainly for the desalination of brackish drinking-water. Brackish water with a high scaling potential can be successfully treated, using the electrodialysis reversal (EDR) process without the addition of chemicals. The reliability of the ED process makes it very attractive for water treatment. Although used mainly for brackish water desalination, ED also has certain industrial applications. Plating wash waters, cooling tower recirculation water and glass etching effluents have been treated successfully with ED for water recovery and effluent volume reduction, while ED treatment of nickel plating wash waters is an established industrial process
