Chino II Desalter Concentration Reduction Facility (CRF)

Butier Engineering, Inc. provided construction management and inspection services for the Chino II Desalter Concentration Reduction Facility (CRF). The CRF—a groundwater treatment facility—is one of two plants managed by the Chino Basin Desalter Authority (CDA). Both ion exchange (IX) and reverse osmosis (RO) treatment trains are used to treat brackish groundwater from eight wells that also had elevated nitrate concentrations.
