Description:
The objective of Faraday Technology's Phase I program is to demonstrate the feasibility of a novel treatment technology for in process recycling of wastewaters generated by the printed wiring board (PWB) and metal finishing industries. Specifically, their electrochemical ion-exchange (EIX) process will enable in-process recycling of both water to rinsing operations and metal salts to plating operations. Conventional ion-exchange allows in-process recycling of rinse water; however, the metal salts are not reusable in the plating process. Conventional electrochemical treatment (electrowinning) allows recovery of metal in metallic form for off-site recycling, however, the metal recovered is not compatible with in-process recycling. Additionally, the treated water from electrowinning cannot be recycled to the rinse operation. In Phase I, they will:
- fabricate EIX cathodes and anodes,
- incorporate EIX electrodes into their existing electrochemical hardware,
- evaluate the EIX process for treatment of lead/tin wastewater representative
of solder plating operations, and
- conduct and economic analysis of the EIX process.
