The PX Pressure Exchanger® (PX®) is a rotary-type energy recovery device (ERD) with only one moving part that recovers energy from the waste stream of seawater reverse osmosis (SWRO) systems at up to 98% efficiency. At the core of the device is a ceramic rotor which resists corrosion and has low vibration, providing maintenance-free and fail-safe operation. PX technology dramatically reduces costs associated with the energy intensive SWRO desalination process by up to 60% as compared to desalination plants without any energy recovery devices. It is also the most widely used ERD today with installations in over 30 countries world-wide. More >>
