Energy Recovery Announces $28 Million in Desalination Contracts for Flagship PX Q400 Energy Recovery Device

Energy Recovery, Inc. (Nasdaq: ERII) today announced the award of contracts totaling over $28 million to supply its newest top-of-the-line PX® Pressure Exchanger® energy recovery device (ERD), the PX Q400, to mega desalination projects in the Gulf region.

These facilities will produce nearly 1.5 million cubic meters of water for municipal use in the Gulf, a significantly water-stressed region, and the awards demonstrate confidence in Energy Recovery's latest innovation, the PX Q400. With the highest capacity and efficiency of any PX® Pressure Exchanger®, the Q400 offers best-in-class performance and the lowest projected life cycle cost of any proven ERD for seawater reverse osmosis (SWRO) desalination due to lower maintenance and operational expenditures.

"The PX Q400 is the new gold standard ERD for SWRO desalination," said Rodney Clemente, Energy Recovery Senior Vice President of Water. "These mega desalination facilities are fulfilling a critical need to supply water in the Gulf at a low cost, and by choosing the PX Q400, our customers are demonstrating trust in our ability to innovate and provide the best performing ERD while continuing to deliver the reliability that they expect from Energy Recovery."

All orders are expected to ship by Q4 2024. When installed, the PX Q400 devices are projected to prevent more than 600,000 metric tons of carbon emissions from entering the atmosphere, which is equivalent to removing roughly 130,000 passenger cars from the road each year.
