Designed to optimize

Solutions built upon decades of engineering expertise

Energy Recovery has spent 30 years perfecting the reliable, field-proven, and trusted PX® Pressure Exchanger® technology. Consuming no electrical power and engineered with only one moving part made of highly durable and corrosion-resistant ceramic, the PX Pressure Exchanger offers substantial energy savings and ease of integration resulting in reduced operational expenditures. Our low-pressure PX solutions are designed for brackish water reverse osmosis (BWRO) applications. It is designed to operate at low pressures of 5.5-27.6 bar (80 – 400 psi) and is ideal for use in potable, non-potable, agricultural, and industrial water reuse.

Peak efficiency

The PX Pressure Exchanger transfers hydraulic energy from the concentrated brine stream and uses it to supplement the flow from the main high-pressure feed pump, which feeds the membranes. This is done via direct contact between the concentrated brine and filtered seawater feed stream. An optional booster pump can be used to balance the fluxes in both stages.

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.
