Reducing Energy Costs in Desalination and Wastewater Treatment

Energy Recovery’s PX Pressure Exchanger Q Series is a range of energy recovery devices that optimize high-pressure seawater reverse osmosis (SWRO) and wastewater treatment systems over various flow ranges for maximum energy savings of up to 60%. Our leading pressure exchangers include the gold standard PX Q650, which delivers best-in-class performance and efficiency.

The PX Q Series of energy recovery devices delivers industry-leading uptime and energy savings, is designed for flexible operation, and can be paired with Energy Recovery’s high-pressure pumps and circulation pumps to maximize efficiency and operational savings.

At a Glance

Highly efficient

Peak efficiency of 99%, optimized for a wide range of pressure levels up to 83 bar (1,200 psi). Operates with concentrate flow from 4.5-147.6 m3/h (20-650 gpm).

Reliable

Industry-leading 30-year design life and 99.8% uptime

Low OPEX

Low SEC, minimizing total cost of ownership

Low Mixing

As low as 2% volumetric mixing, resulting in higher system performance
