CLOSED-LOOP WATER SYSTEMS Crest Ultrasonics Corp. www.crest-ultrasonics.com Closed-loop water systems are used for removing organ- ic and inorganic contamination from water through con- tinuous reciruclation. This is accomplished by pssing effluent rinsewater through carbon beds to remove organics followed by ion exchange to remove the inor- ganic impurities. When used with an ultrasonic cleaning system, spray system, or overflow rinse system, the rin- sewater flows into the CLWS process sump. The water is then pressurized and sent through the purification sys- tem at a controlled flow with visual monitoring and automatic mechanical controls. Water losses from dragout and evaporation are automatically added to the system using tap water feed. Circle 165 on reader information card
