Electrochemical treatment of spent electroless nickel solution

Electroless nickel (EN) coatings are widely used in the manufacture of auto motive parts, providing uniform coating, corrosion protection, wear resista nce and lubrication contrast to EN plating benefits, the disposal and treat ment of waste solutions can cause many difficulties. The use of electrochem ical treatment technology greatly improves the operation; the main wastewat er treatment,cess and reduces operation A new, state-of-the-art, jobshop in the Chicago area that provides EN plating for the automotive industry has installed a large separated electrolytic cell for the treatment of spent EN solution (from dumps and wastewater). The wastewater is handled by the sep erated electrolytic cell, batch treatment system, filter press and neutrali zation station. The implementation of modern electrolytic technology and au xilliary equipment provides an effective waste treatment process that meets environmental compliance criteria.
