Energy Recovery reduces desalination’s overall costs in Mexico

Posted by: Maven on August 2, 2009 at 7:55 am

From Water World:

“Efficiency and lifecycle costs of a seawater reverse osmosis (SWRO) desalination plant's energy recovery technology are critical to both winning SWRO projects and achieving maximum plant profitably through the lowest operating costs.

Spanish contractor Inima was awarded the new 20,000 m3/day Cabo San Lucas Desalination Plant project located in Baja California, Mexico. With no prior experience using Energy Recovery Inc.'s technology, Inima selected PX Pressure Exchanger ® (PX ®) devices as the energy recovery solution for the largest plant in Mexico. The plant operates with a pressure center design (common high-pressure feed header and common concentrate header) to provide operational flexibility and minimize process downtime.

The ERI device is a rotary positive displacement pump that recovers energy from the high-pressure waste stream of SWRO systems at up to 98% efficiency with no downtime or scheduled maintenance. At its core is a single moving rotor made of tough engineered ceramic that's unaffected by chemicals, won't corrode and requires no periodic maintenance. Over 80 OEMs are standardizing on this technology with installations around the world, including desalination plants such as Al Shuaibah III, Barcelona, Chennai, Hamma, Perth, Skikda, Torrevieja and Yuhuan. …”
