Industry Applications

PX Pressure Exchangers and Turbochargers can be used in compact freshwater production, including:

  • Containerized desalination
  • Barges and other marine desalination systems
  • Hospitality, including hotel desalination
  • Desalination for agriculture use
  • Brackish applications

The Solution

While large-scale desalination plants can provide critical freshwater to entire regions, smaller scale applications are vital to supply water to operations on the go. This includes serving employees on long-haul shipping and fishing vessels, guests and crew on cruise ships, hotels, decentralized water systems, power plants, mining, isolated locations, expansion projects or other scenarios where water is needed quickly. 

Energy Recovery’s PX® Pressure Exchangers® and turbochargers provide unmatched savings and reliability for small seawater reverse osmosis (SWRO) desalination systems as small as 100 m3/day or as large as 50,000 m3/day with ease of integration and simple installation and advanced durability and performance.

Desalination Products

Energy Recovery offers a complete catalog of energy efficient products for smaller desalination systems to lower operational costs and reduce energy consumption, all while slashing harmful carbon emissions.  

In addition to the PX, Energy Recovery’s family of high-performing turbochargers serve projects with smaller budgets, or where there is a need to mitigate upfront capital spending. Easy to operate and simple to service, turbochargers allow staff to quickly adjust to operating conditions as needed while maintaining facility uptime.

Energy Recovery’s line of high-pressure and booster pumps pressurize feedwater to meet reverse osmosis membranes requirements. Delivering pressures up to 83 bar (1,200 psi), our pumps are designed to stand up to the operational and environmental demands of a high-pressure RO system.

How it works

Frequently Asked Questions

Our PX devices (pressure exchangers and turbochargers) are ideal for compact, modular or containerized RO systems because they deliver high energy-recovery efficiency in small footprints. They enable easy integration and dependable performance in any size desalination units, making them well suited for ship, hotel, mining, remote or barge-based systems.

Implementing PX energy-recovery devices in modular RO systems significantly lowers power consumption and operating cost. By capturing the high-pressure brine reject and reusing its energy, the high-pressure feed pump’s workload is reduced—driving down OPEX and improving life-cycle cost. Additionally, the compact, modular design means reduced footprint, faster installation and simpler logistics, especially beneficial for containerized or mobile RO units.

Designers should match the PX model to the system’s pressure, flow and feed conditions (e.g., brine reject rate, system recovery, variability). The device must fit the modular footprint and align with the RO system’s layout, whether new build or retrofit. It also should deliver high uptime and minimal maintenance to suit modular operations. Proper selection and integration maximize energy savings and ensure a smooth plug-and-play modular solution.
