On April 2, 1999, The Board of Directors of the Water Replenishment District (WRD) approved the award of a 3.5 MGD Microfiltration Plant to Pall Corporation. Pall Corporation’s Microfiltration Plant will be a cornerstone of the recycled water project. Pall Corporation in conjunction with the engineering teams of Separation Processes Inc. (SPI) and Camp Dresser McKee (CDM) will provide the skid mounted microfiltration plant as a prefilter for the Reverse Osmosis (RO) plant. The plant furnished by Pall Corporation will be similar to the 1 MGD MF plant installed at the OCWD Factory 21 facility, located in Fountain Valley, Ca., as shown on the following pictures.
The drastic decline of the water tables levels in the late 1950’s allowed salt water to seep into the groundwater basin. This intrusion contaminated wells and caused significant loss of groundwater storage capacity. Seawater intrusion barriers were constructed to inject freshwater to raise the groundwater levels and stop this flow. Currently, water for the barriers is from imported water supplies. WRD and the Orange County Water District (OCWD) in cooperation with the City of Long Beach have joined forces on an innovative recycled water project for one of the barriers. Designed to substitute highly treated recycled water for the imported water currently used, the Alamitos Barrier Recycled Water Project consists of a water reclamation plant and facilities to transfer treated water for injection into barrier wells located along the coast in Long Beach. Information gathered from this project will promote the safe and beneficial use of recycled water not only for California, but for the entire nation as well. The increased use of recycled water will lower the dependence of unreliable and expensive out-of-state and Northern California water resources. In addition, this use will promote a greater reliance on local resources.
