The objective of this SBIR project is to develop and commercialize a novel electrochemical/electrodialysis system for in-process recycling of a spent electroless nickel (EN) plating bath. Currently, there is no technology available to treat the spent EN bath for in-process recycling. Additionally, current waste treatment processes generate a large volume of toxic sludge and, therefore, waste disposal costs are high. The proposed system will convert H2PO3, which has an adverse effect on EN deposits, to H2PO2, which is a usable component in EN, without altering the other bath constituents. Consequently, the treated bath can be in-process recycled to the EN plating operation. The system will have potential applications in aircraft, automotive, electronics, surface finishing, and other industries dealing with electroless nickel plating operations.
