Energy Recovery PX Q180 Pressure Exchanger

Energy Recovery's award-winning PX® Pressure Exchanger® (PX) family of products provides unmatched energy recovery for seawater reverse osmosis (SWRO) desalination systems. Large and small desalination projects around the world rely on this 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 of environments resulting in an unmatched life-cycle cost advantage.


* Historically energy consumption and costs made SWRO uneconomical. With the PX Pressure Exchanger, up to 60% of that wasted energy can be recycled, driving substantial savings and emission reductions. In addition, the size and/or number of high pressure pumps can be decreased.


Superior Precision and Durability:

The PX cartridges have only one moving part and are made with high-purity aluminum oxide ceramic. They’re corrosion-proof and three times more abrasion-resistant than steel. All that adds up to unmatched durability.

We design and manufacture ceramic PX components in-house at our California headquarters. This allows us to control the precision and quality of our core components down to the micrometer level, ensuring every PX device performs with maximum efficiency, durability, and reliability.

Features:


Quiet operation
PX Q devices offer operational sound levels below 79 decibels—comparable to a home vacuum cleaner—to enhance the safety of SWRO plant working environments through reduced audio levels.


Productive
PX Q devices provide reduction in fluid mixing, resulting in lower membrane feed salinity and pressure, and higher desalination system performance.

Scalable
Up to 40 parallel PX Q devices have been successfully installed in a single train, with 10 to 16 PXs commonly installed in parallel.

Efficient

PX Q devices perform with unparalleled efficiency—up to 98%.

Advantages:

Efficiency
Designed for maximum efficiency, the PX consumes no electrical power, enabling SWRO facilities to reduce their energy consumption by as much as 60%.


Performance
With no scheduled maintenance and proven performance for the long run, our PXs offer unbeatably low life-cycle costs.

Flexibility
Our range of PX capacities provides flexibility to optimize train size to specific project requirements, making the PX the ideal solution for new installations and retrofits alike.
