March 7, 2017 | Gilad Cohen, CEO of IDE Americas, discusses the membrane technology used in the Carlsbad Desalination Plant
The Claude “Bud” Lewis Carlsbad Desalination Plant, owned by Poseidon Water, was recognized at the Membrane Technology Conference as ‘Membrane Facility of the Year.’ The Carlsbad plant, located in San Diego County, is a seawater desalination plant using reverse osmosis technology and is the largest desalination plant in the Western Hemisphere. IDE’s technology has created a highly-efficient use of membranes in an environmentally-friendly approach. In Carlsbad, IDE has implemented 144 energy recovery devices which save 44 percent of the energy. The energy recovery devices work by capturing the hydraulic energy created by the high pressure reject stream of seawater produced during the reverse osmosis processes and transfers it into incoming seawater, without consuming any electrical power themselves. This process saves 146 million kilowatt-hours of energy and prevents 42,000 metric tons of carbon releases. Carlsbad currently produces 54 million gallons of water per day.
This acknowledgement adds to the award-winning Carlsbad plant which was also recognized as ‘Desalination Plant of the Year’ and ‘North American Water Deal of the Year’ by Global Water Intelligence and Project Finance respectively.
