Industrial Wastewater

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.

Along with the Ultra PXTM for ultra high-pressure systems, our PX® Pressure Exchangers®, turbochargers, and pumps offer a full slate of energy recovery devices that cover a range of pressure levels and flow rates to accommodate any size plant, or multiple stages of a membrane-based industrial wastewater treatment system.  These devices are able to capture lost energy and recycle it back into the system to increase energy efficiency and reduce operating costs and emissions.

The Pressure Exchanger® is the market leader in energy saving devices for the seawater reverse osmosis (SWRO) desalination industry, with over 25,000 PX devices installed in over 100 countries over the last 30 years. Our customers in SWRO save approximately $3.9 billion in energy costs each year, and the PX can offer the same energy saving benefits for industrial wastewater treatment facilities.

Operating at pressures of up to 120 bar (1740 psi), the Ultra PXTM brings the benefits of the PX to ultra high-pressure reverse osmosis systems.

PX and Ultra PX benefits

  • Up to 98%* of the wasted energy is recovered
  • Up to 60% energy savings from recovering wasted energy
  • Up to 60% reduction in high-pressure pump size

*PX has peak efficiency of up to 98%, Ultra PX has peak efficiency of up to 93%

The PX and Ultra PX have a simple design with just one moving part and no controls or electronics to boost reliability, making them easy to install and scale. They require no scheduled maintenance to maximize facility uptime and are effective under a wide range of operating conditions, providing efficiency and savings even as flow rate, pressure, or salinity levels change.

Combined with our Turbochargers, which provide energy recovery for low-pressure stages, and our UHP Pump, which is designed to work in conjunction with the Ultra PX, our range of energy recovery products can provide benefits for any membrane-based industrial wastewater treatment facility.

Energy Recovery Devices

Ultra PX

Energy Recovery’s Ultra PX™ energy recovery device for ultra high-pressure reverse osmosis (UHPRO) wastewater treatment dramatically reduces the energy needs, costs, and emissions associated with treating industrial wastewater discharge with UHPRO.
