Case Study / Desalination
As drought, climate change, and water scarcity increase the demand for water systems, ensuring a sustainable method of providing fresh water is essential. For over 30 years, Energy Recovery has partnered with customers to drive operational efficiency in clean water production. Our solutions are critical to optimizing energy consumption and reducing emissions in reverse osmosis systems, making SWRO more affordable and contributing to a water-secure future. By utilizing Energy Recovery’s products, customers have avoided 22.5 million metric tons of carbon emissions annually.
Our high-pressure PX solutions offer unmatched energy recovery for seawater reverse osmosis (SWRO) desalination and wastewater treatment systems and operate at a wide range of pressure levels up to 83 bar (1200 psi). Large and small desalination projects worldwide rely on our range of PXs to achieve optimal operations and maximum energy savings. Designed with only one moving part using highly engineered alumina ceramic, the PX stands up to the harshest environments, resulting in an unmatched life cycle cost advantage.

Featuring a wide range of PX capacities, our high-pressure solutions provide flexibility to optimize train size to specific project requirements, and they’re the ideal solution for new installations or retrofits. Consuming no electrical power and engineered with only one moving part made of highly durable and corrosion-resistant ceramic, they’re the most efficient and reliable energy recovery solution for desalination and wastewater treatment on the market.

The PX Q Series is the gold standard in energy recovery devices. It includes the PX Q650, PX Q400, PX Q300, PX Q260, PX Q220, PX Q180, and PX Q140.
PX Q devices offer low operational sound levels to enhance the safety of SWRO plant working environments.
Low SEC, minimizing total cost of ownership
PX Q devices perform with unparalleled efficiency—up to 99%.
Specially designed options available for small and medium size plants: PX 90, PX 70, PX 45, and PX 30
Offers 97% peak efficiency
Can be installed in parallel according to specific plant needs
Lower the energy consumption of water treatment for reduced greenhouse gas emissions


The PX PowerTrain™ pre-engineered energy recovery solution combines Energy Recovery’s trusted PX® Pressure Exchanger® devices with frame support and ancillary equipment into a compact, ready to install high-performance energy recovery device array package for your seawater reverse osmosis train.
When coupled with our SWRO pumps, a complete end-to-end ERD solution.
Pre-designed ERD and frame support for ease of installation, and 3D models are available for easy integration into plant design.
Train production capacity starting from 3000 CMD.
Work with a single trusted supplier from design to installation.
The PX Q series offers exceptional energy recovery efficiency of up to 99%. By capturing the pressurized brine reject stream and transferring that energy back to feed water, the PX helps reduce the duty on the high-pressure pump and thereby lowers the specific energy consumption (SEC). The PX is the gold-standard of any large desalination plant across the globe.
The PX Q650 delivers roughly 63% higher unit capacity over the previous model, meaning fewer modules are required for the same throughput. The higher capacity and reduced mixing result in lower capital cost, reduced plant footprint and simplified installation. In addition, the PX Q650 has a 30-year design life with no scheduled maintenance, which improves uptime and lowers life-cycle cost.
The High-Pressure PX is built with only one moving part and corrosion-resistant ceramic internal components, engineered in-house for micrometer precision. This design delivers industry-leading reliability and uptime (reported 99.8 % in the PX Q series) with minimal maintenance needs. Because it can operate over a wide range of pressures (up to 83 bar / 1,200 psi) and flow rates, it integrates easily into SWRO trains, wastewater-recovery systems or high-recovery applications. The simplified installation enables faster timelines and lower risk of operational interruptions.
