SAN LEANDRO, Calif. — April 23, 2019 — Energy Recovery, Inc. (NASDAQ:ERII), the leader in pressure energy technology for industrial fluid flows, today announced the shipment of its 20,000th PX Pressure Exchanger unit.

“Our PX Pressure Exchangers have enabled our customers around the globe to reduce the operating costs and the environmental footprint of their water desalination operations.  Today, desalination plants using our technology produce enough fresh water to meet the daily consumption of approximately 52 million people,” said Energy Recovery President and CEO Chris Gannon. “The recent United Nations World Wide Water report found that water use has risen roughly one percent per year since the 1980s, and global potable water demands are expected to increase up to 30 percent by 2050.  Our role in reducing the cost of providing clean, fresh water and helping to meet these challenges is a source of pride for Energy Recovery, and we continue to innovate our product and solutions offerings in the water industry and beyond.”

The PX Pressure Exchanger, which was first introduced over 20 years ago, revolutionized the economics of seawater reverse osmosis (SWRO) desalination by recycling pressure energy that would otherwise be lost in the desalination process.  The technology reduces the energy costs of converting seawater to fresh water via SWRO desalination by up to 60 percent.  In 1997, Energy Recovery installed its first PX Pressure Exchanger in the Canary Islands.

“I started my career with Energy Recovery two decades ago when the PX Pressure Exchanger had just recently been commercialized.  At that time, we were at the very beginning of tapping into the technology’s game-changing potential for the emerging SWRO desalination industry.  Since commercialization, we have increased the performance, reliability, and durability of our technology while becoming the energy recovery solution of choice for SWRO plants of all sizes,” shared Energy Recovery Vice President of Water Rodney Clemente.  “From our humble beginning in Chesapeake, Virginia, we have now deployed our PX Pressure Exchanger technology across all seven continents, helping to produce over 17 million m3/d of fresh water.  We are truly humbled and extremely proud of this milestone, and we look forward to continuing to support our industry partners in bridging the gap between the global water supply and demand imbalances.”

Energy recovery devices like the PX Pressure Exchanger have greatly influenced the trajectory of the SWRO desalination industry.  An Energy Recovery-produced infographic exploring this history can be found here:
