PRODUCTION OF HIGH PURITY WATER FROM ELECTROPLATING PROCESS RINSE WATER

An electronics manufacturer planned to relocate its electroplating process to an existing facility that was located in an arid region where periodic drought conditions trigger water rationing. In the event of water rationing, the facility's groundwater extraction permit did not allow sufficient with drawl to meet process requirements. The industry wanted a sustainable solution that was appropriate for the site's climatic constraints.The primary goal of the project was to develop and install an electroplating rinse water treatment and recycle system that would allow the facility to operate in an unrestricted manner using the permitted groundwater extraction rates. Project objectives included developing a system that could utilize either municipal or ground water supplies, operate in a once through or recycle mode, and produce electronics grade water.
