Reversing the Flow – Full-Scale Design Considerations for Flow Reversal Reverse Osmosis

The City of Santa Monica has limited additional local water supplies available and is seeking the most cost-effective and sustainable technology capable of squeezing as much production as possible from the existing Arcadia Water Treatment Plant. Between June to December 2020, two high-recovery reverse osmosis technologies were piloted simultaneously in an existing brackish groundwater treatment […]

The First U.S. Installation of a BWRO Pressure Exchanger

Energy recovery technologies such as the pressure exchanger (PX), have previously focused on seawater RO applications due to the rather quick payback. This leaves brackish water RO (BWRO) facilities to turbochargers that yield less efficient transfer of energy than their PX counterparts. Recently, the first municipal BRWO application of a PX energy recovery device was […]

A Plethora of Seawater Intakes Which Will Be Selected?

The Claude “Bud” Lewis Carlsbad Desalination Plant (CDP), pictured in Figure 1, has been operating for nearly 3 years, producing approximately 50= million gallons per day (MGD) to meet 10 percent of the City of San Diego’s daily potable water demands. The plant has been operating under a temporary State Water Quality Control Board (Water […]

Using MBR for On Site Water Recovery in New Mexico – Challenges and Solutions

The Albuquerque Bernalillo County Water Utility Authority (Water Authority) is developing a state of the art on site water resources recovery plant, located at a shopping center in the uptown district of Albuquerque. The Winrock Town Center was originally constructed in the early 1960s and is currently undergoing a complete renovation. The vision for the […]
