Carlsbad Desalination Project to reduce energy costs using new technology

Aug. 5, 2013

SAN LEANDRO, Calif. — IDE awarded Energy Recovery a contract for its innovative energy recovery device technology to the project.

SAN LEANDRO, Calif. — Energy Recovery Inc. announced that its technology will be used in the Carlsbad Desalination Project to help reach its ambitious carbon neutral goals, while significantly reducing overall energy costs, according to a press release.

IDE, technology provider and future operator of the plant, awarded Energy Recovery a contract for its innovative energy recovery device (ERD) technology to the project, which will be the largest desalination plant in the western hemisphere.

As part of the agreement, Energy Recovery will provide 144 of its PX Pressure Exchanger Q300 units to the seawater reverse-osmosis (SWRO) plant, aiding the estimated production output of 189,250 cubic meters of desalinated water per day (equivalent to 50 million gallons per day). The units are expected to ship by the end of the year, noted the release.

By choosing the PX technology, the vanguard project for California’s first large-scale plant will save an estimated 116 million kWh (kilowatt-hours) of energy per year, the equivalent of $12 million.

This energy savings will also reduce CO2 emissions by 41,000 metric tons per year — roughly the annual greenhouse gas emissions from 8,542 passenger vehicles.
