Ion exchange system for electroplating and steel pickling acids
In electroplating and steel pickling operations, the challenge of contaminant buildup and lost metal salts poses significant cost and performance issues. Maintaining bath chemistry while reducing waste and chemical expenses is critical for efficiency and quality control.
Recover and purify metal salts from plating baths
The ChromaPur™, NickelPur™, and MicroPur™ systems from Kovalus Separation address these challenges using advanced ion exchange techniques. The ChromaPur™ system targets chrome plating baths, removing dissolved contaminants through a resin bed to purify chromic acid, which is then reused. The NickelPur™ system employs a counter-current compressed-bed operation to recover over 95% of nickel lost during electroplating. It concentrates and de-acidifies nickel salts, which are later reintroduced to the baths. For smaller steel pickling operations, the MicroPur™ system, based on the APU® system, removes dissolved metals from pickling acids, eliminating the need for bath dumping. These systems offer predictable performance, lower waste treatment costs, and enhance product quality.
