Nickel Plating Salt Recovery

Ensuring Greater Savings & Plating Performance

Eco-Tec’s Nickel Recovery System – NickelPur™ — ensures maximum nickel salt recovery, cost reduction, and quality Consistency.  NickelPur™ utilizes Recoflo®, the next generation of ion-exchange technology with compressed-bed, counter-current technology – recovering over 95% of nickel dragged out from the plating baths into the rinses.

How it Works

The combination of ion exchange resin and acid sorption resin ensure the effective recovery of nickel in electroplating operations. The cation exchange and acid sorption beds are coupled in a manner that produces a concentrated de-acidified nickel salt product. Rinse water is pumped through cartridge filters and then through the strong acid cation resin bed where the nickel is exchanged on the resin. Regeneration is accomplished using a mixture of sulfuric and hydrochloric acids, which are pumped into the cation resin bed. Regeneration yields a concentrated nickel sulfate and nickel chloride product, which then passes through the de-acidification bed to remove excess acids. The resulting concentrated, purified, pH adjusted, nickel chloride/nickel sulfate product is stored and added to the plating baths as required.

Why Use NickelPur?
“Nickel drag-out” is a normal operational occurrence during the electroplating process that normally results in nickel loss and additions to sludge compounds. Operational costs related to both the replenishment of the nickel, and sludge waste disposal can seriously impact an operation’s efficiency. The NickelPur™ is specifically designed and manufactured to assist companies in their efforts to increase efficiencies, and lower waste and operating costs.
