For more than 20 years, we’ve pioneered technologies that have become the industry standards for energy recovery solutions.

Scalable Solutions for Global Desalination

The world’s need for clean water is intensifying, driven by population growth, industrialization, rapid urbanization, and climate change. According to United Nations estimates, global demand for water will surge 30% by 2050. Even today, nearly 2 billion people experience extreme water stress year-round.

These trends make desalinating water increasingly vital to quench global thirst. As the industry leader in energy recovery devices (ERDs), we’re actively deploying highly efficient, scalable solutions for recovering otherwise wasted energy in the seawater reverse osmosis (SWRO) desalination process.  Our flagship PX® Pressure Exchanger® (PX) ERD saves water desalination customers approximately USD $2 billion annually in energy costs*. In 2019, the PX, which generates no emissions when operating, also helped our customers avoid 21 terawatt hours and approximately 12.4 million metric tons of carbon emissions – equivalent to removing more than 2.5 million passenger vehicles from the road annually*.  As water scarcity grows in communities across the globe, we are proud of our impact in enabling more affordable, sustainable access to this critical resource.

PX Pressure Exchanger

Our flagship PX isobaric technology is the most efficient and reliable energy recovery solution for desalination on the market.


Suitable for both high-pressure seawater and low-pressure brackish reverse osmosis systems, our turbochargers offer substantial savings for lower investment solutions.

Pumping Systems

We offer high-pressure multi and single stage centrifugal pumps designed to complement our energy recovery devices for any size reverse osmosis plant.

PX PowerTrain™

The PX PowerTrain™ line of pre-engineered energy recovery solutions combine Energy Recovery’s award-winning PX® Pressure Exchanger® (PX) devices with frame support and ancillary equipment into a compact, ready to install high-performance energy recovery device (ERD) array package.

Ultra PX

Energy Recovery’s Ultra PX™ energy recovery device for Ultra High-Pressure Reverse Osmosis (UHPRO) wastewater treatment dramatically reduces the energy needs, costs and emissions associated with treating industrial wastewater discharge with UHPRO.
