Desalination
As the global need for freshwater increases, desalination—the process of turning saline water into freshwater—is becoming more important. Energy Recovery’s solutions lower the energy consumption of seawater reverse osmosis (SWRO), making it more efficient and cost-effective.
How it works
The challenge
Droughts, extreme weather, and growing populations are driving many water-stressed regions to look for diversified and sustainable water production strategies to build a secure water future. SWRO desalination can reliably produce clean water by physically filtering it through a membrane. Although this process can be energy intensive, energy recovery devices significantly lower the energy consumption of water production, making it cost-effective while reducing emissions.

The Solution
Without an Energy Recovery Device (ERD), a high-pressure pump pushes water into a reverse osmosis system that results in wasted energy. Equipped with a PX® Pressure Exchanger®, the rejected water is fed back into an ERD that recovers energy that powers a circulation pump, reducing energy demand on the high-pressure pump. The PX ultimately creates a desalination process that both optimizes performance and maximizes savings.
