Abstract
The southwestern United States, specifically the Albuquerque, NM area, was chosen as the target location for implementation of the Project ZERO design due to the volume of electronics manufacturing facilities in the area and the critical need to conserve water. The WERC RO reject sample, believed to originate in chemical mechanical polishing, contains high amounts of silica, trace heavy metals, and salt compounds that would negatively impact water quality if it were discharged into surface waters. Because of the high levels of silica, special precaution must be taken when utilizing membrane or mechanical evaporation technologies due to fouling and scaling problems. Project ZERO recovers over 97% of the water with zero liquid discharge (ZLD) and 100% of the solids for productive use. The recovered water will be recycled within the facility, thereby eliminating water discharge, reducing water intake, and lowering operating expenses.
