Optimize your operations

Best-in-class energy recovery for desalination and wastewater treatment

As drought, climate change, and water scarcity increase the demand for water systems, ensuring a sustainable method of providing fresh water is essential. For over 30 years, Energy Recovery has partnered with customers to drive operational efficiency in clean water production. Our solutions are critical to optimizing energy consumption and reducing emissions in reverse osmosis systems, making SWRO more affordable and contributing to a water-secure future. By utilizing Energy Recovery’s products, customers have avoided 19.7 million metric tons of carbon emissions annually.

Our high-pressure PX products provide highly efficient energy recovery for SWRO desalination and water treatment systems. Large and small desalination projects worldwide rely on our range of PXs to achieve optimal operations and maximum energy savings. Designed with only one moving part using highly engineered alumina ceramic, the PX stands up to the harshest environments, resulting in an unmatched life cycle cost advantage.

Desalination

As the global need for freshwater becomes more critical, desalination—the process of turning saline water into freshwater—is becoming more important with each passing day. However, as vital as the process is, desalination consumes a significant amount of energy. We're here to change that.

Wastewater

Membrane technologies now offer an energy-efficient and cost-effective way to meet regulations requiring minimal liquid discharge (MLD) and zero liquid discharge (ZLD) for wastewater treatment.
