Large-Scale RO Systems
Including the gold-standard PX Q series, Energy Recovery’s PX products provide unmatched energy recovery for large seawater reverse osmosis (SWRO) desalination and water treatment systems.
PX Q400: At a Glance
Highly efficient
Highest efficiency at the highest flow compared to our other PX products
Lower mixing
<3% volumetric mixing resulting in higher system performance
Higher capacity
At 400 gpm, it’s our highest capacity PX yet, needing 25% fewer devices *
Low life cycle cost
Offers the lowest projected life cycle cost of any proven ERD for SWRO desalination due to lower maintenance and operational expenditures
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 30-year design life with no scheduled maintenance, leading to incredibly low design life costs, high uptime, and industry-leading reliability.

Without an Energy Recovery Device (ERD), a high-pressure pump pushes water into a reverse osmosis system where there is rejected seawater that ends up being wasted energy. Equipped with a PX® Pressure Exchanger®, the rejected water is fed back into an ERD that recovers energy and then powers a circulation pump that reduces energy demand on the high-pressure pump—creating a desalination process that’s both optimized and maximizes savings.
