For more than 30 years, we’ve pioneered technologies that have become the industry standards for energy recovery solutions.

The Importance of 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.

Saving Energy During Seawater Reverse Osmosis

Thermal desalination is a highly energy intensive process used to transform saline water into drinkable water by vaporizing the water, separating it from the solid salts. Another desalination process, seawater reverse osmosis (SWRO), involves physically filtering water through a membrane, but historically this process has also been energy intensive and has proven uneconomical. However, advances in energy recovery devices, membranes and other technology have contributed to the affordability of the SWRO process in recent years. At Energy Recovery, we’re invested in the evolution of energy recovery devices for the SWRO desalination process to help reduce energy consumption and make it sustainable—helping bring freshwater to more people, everywhere.
