PX Q400

PX Q400

Our most efficient, highest-capacity PX for seawater reverse osmosis desalination facilities.

The PX Q400 offers best-in-class performance from Energy Recovery’s 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 provides superior performance from the most trusted ERD in desalination – enhancing efficiency, capacity, reliability, and value. At 77 dB, the PX Q400 is the quietest ERD on the market.

Highly efficient

Highest efficiency at the highest flow compared to our other PX Pressure Exchanger products

Lower mixing

<3% volumetric mixing resulting in higher system performance

Higher capacity

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 proven 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, high uptime, and industry-leading reliability.

Desalination

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.

A breaking wave

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.
