The GWRS is the world’s largest advanced water purification system of its kind for potable reuse. The system takes treated municipal wastewater that would otherwise be discharged to the Pacific Ocean and purifies it using a three-step advanced purification process consisting of microfiltration, RO and ultraviolet light with hydrogen peroxide. The process produces high-quality water that meets or is superior to all state and federal drinking water standards. The water is used to recharge the Orange County Groundwater Basin as a drinking water supply via surface spreading and injection into coastal wells as a seawater intrusion barrier. GWRS water is a highly reliable source, even during times of drought.
“As a leader in the implementation of RO technology for municipal and industrial clients, CH2M recognizes the potential for the Desalitech CCD technology to be a game changer for a wide range of desalination applications and in particular for increasing RO energy efficiency and water recovery in a reliable manner while reducing the costs associated with concentrate management. We look forward to partnering with Desalitech and OCWD in pilot testing of CCD for concentrate recovery at the GWRS,” says Jim Lozier, P.E., Global Technology Leader – Desalination, CH2M.
