The Energy Recovery team celebrates the shipment of the 20,000 PX

Energy Recovery, a supplier of pressure energy technology for industrial fluid flows, has shipped its 20,000th PX pressure exchanger unit.

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

The technology is designed for any size reverse osmosis desalination plant, the claims to deliver the lowest lifecycle cost of any energy recovery device on the market, and operates at 98% efficiency. 

Water use rise
"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% by 2050.
