Low-pressure PX
Ideal for brackish water reverse osmosis and water reuse in municipal and industrial applications, our low-pressure PX solutions offer substantial energy savings and ease of integration.
Designed to Optimize Water Reuse
Solutions for sustainable water treatment for industrial and municipal systems
Energy Recovery’s low-pressure PX® Pressure Exchanger® can drive operational efficiency in clean water production for low-pressure systems, providing a sustainable path to saving operational energy. By reducing the energy consumption of low-pressure reverse osmosis, our PX solutions reduce the emissions associated with industrial and municipal reuse, enabling a circular water economy and preventing harmful discharge into the environment. The low-pressure PX is designed for brackish water reverse osmosis (BWRO) and wastewater reuse applications, operating at low pressures of 5.5-27.6 bar (80 – 400 psi) and is ideal for use in small and large municipal and industrial plants, making the production and recycling of water financially and environmentally sustainable.

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.
