Energy Recovery, Inc. (ERI) is the global leader in high efficiency energy recovery products and technology. Our PX Pressure Exchanger® (PX®) energy recovery device is driving the rapid growth of the seawater reverse osmosis (SWRO) industry and making desalination affordable. The PX® is a rotary positive displacement pump that recovers energy from the high-pressure waste stream of SWRO desalination systems at up to 98% efficiency with no downtime or scheduled maintenance. Since its introduction in 1997, PX® technology has emerged as the industry standard solution for SWRO desalination. There are currently over 6,000 PX® units sold or contracted in SWRO plants worldwide, significantly reducing the cost to produce over 5.2 million m3/day of fresh water - saving customers an estimated 500 MW of energy or $352 million a year in operating costs. And the PX® comes with an industry first 5 year standard warranty.
ERI’s headquarters is situated in the San Francisco Bay Area; San Leandro, California USA with offices in every continent of the globe including: Sunrise, Florida; Madrid, Spain; Dubai, United Arab Emirates; Shanghai, China; and service representatives in Sydney, Australia. As the world demand for clean, potable water increases; ERI continues to strategically open locations in key cities around the world. With sales representatives already positioned in key parts of the world, ERI is poised to face the global challenges ahead.
ERI was the first company in the world to demonstrate
an SWRO plant producing fresh water for only 2.0 kWh/m³ (7.5
kWh/1,000 gal) - an achievement formerly thought impossible. Recently,
working with the Affordable Desalination Collaboration (ADC) in
California, which has proven 1.6 kWhr/m³ on Pacific Sea Water
with off-the-shelf high efficiency equipment. www.affordabledesal.com
