Our most efficient, highest-capacity PX for seawater reverse osmosis desalination facilities.
Building upon Energy Recovery’s track record of best-in-class performance, the PX Q400 is the next evolution of our industry-leading PX® Pressure Exchanger® technology. Delivering energy and cost savings, the PX Q400 offers the lowest projected life cycle cost of any energy recovery device (ERD) for seawater reverse osmosis (SWRO) desalination, thanks to high performance and lower maintenance. The PX Q400 further innovates and improves upon what came before—enhancing efficiency, capacity, reliability, and value to ensure it remains the most trusted ERD in desalination.
Highest efficiency at the highest flow compared to our other PX Pressure Exchanger products
<3% volumetric mixing resulting in higher system performance
At 400 gpm, it’s our highest capacity PX yet, resulting in 25% fewer devices compared to the Q300*
Lowest life cycle cost
Offers the lowest projected life cycle cost of any ERD for seawater reverse osmosis (SWRO) desalination due to lower maintenance and operational expenditures
Built on a Foundation of Reliability
Designed for the Long Haul
Constructed from corrosion-resistant ceramic and designed with only one moving part, the PX Q400 is easy to use, highly durable, and ideal for harsh desalination environments. These ceramic components are unique and machined in-house using our vertically integrated and highly specialized manufacturing processes, which create precision down to the micrometer level and a consistently high performing product. The PX Q400 supports a 25-year design life with no scheduled maintenance, leading to incredibly low design life costs and high uptime.

The world’s need for clean water is intensifying, driven by population growth, industrialization, rapid urbanization, and climate change. According to United Nations estimates, global demand for water will surge 30% by 2050.
Industrial Wastewater Treatment
Membrane technologies now offer an energy and cost-effective way to meet regulations requiring minimal liquid discharge (MLD) and zero liquid discharge (ZLD) for wastewater treatment. By employing energy recovery devices, those savings can be compounded while preserving system reliability and operability.
