Meta-Treat EN is a waste treatment additive for spent Metal-Chem Inc. electroless nickel solutions. This process reduces nickel metal levels from 6,000 ppm to below 5 ppm in 2-4 hours without creating sludge. The Meta-Treat EN process is simple, inexpensive and can be carried out in your EN tank thus eliminating the need to invest in costly waste treatment equipment. The Meta-treat EN process eliminates serious liability risks EN platers assume when they have their spent solutions hauled away for treatment or recycling. The Meta-Treat EN process is designed for use on all Metal Chem Electroless Nickel Plating baths.
