Energy Savings and Ease of Integration
Our family of efficient and reliable turbochargers offers substantial energy savings and ease of integration into desalination systems. Suitable for both high-pressure seawater and low-pressure brackish reverse osmosis desalination, our turbochargers are easy to operate and simple to service.
Efficiency in One Compact Package
Every Energy Recovery turbocharger consists of a single-stage turbine impeller connected to a single-stage pump impeller via a common shaft. All hydraulics are housed within the casing, with no seals required. The turbine impeller absorbs the hydraulic energy of the concentrate stream and converts it into mechanical energy. This energy is then transferred to the pump impeller. The impeller converts the mechanical energy back to hydraulic energy, providing an additional pressure boost to the feed stream of brackish or seawater reverse osmosis (SWRO) systems.
Perfected for High-Pressure Environments
The AT Turbocharger is an efficient, versatile, and reliable solution designed with a compact footprint—no instrumentation or additional equipment is necessary. In addition, it requires minimal installation time and operator training. With the turbocharger’s completely removable and replaceable hydraulics, plant staff can quickly and inexpensively change operating conditions as needed while maintaining facility uptime.
This modular technology consists of pump and turbine volutes, a turbine nozzle and pump-side discharge diffuser. Ideal for any size SWRO system, the AT Turbocharger handles flows from 11 to 2,272+ m3/h (10,000+ gpm) and pressures from 27 to 83 bar (400 to 1,200 psi). For a centrifugal solution, the innovative volute insert technology allows systems to perform within a best efficiency range rather than at a single best efficiency point. If system conditions change, requiring a new operating point, these lightweight inserts can be removed and replaced in hours instead of days or even weeks, maximizing facility uptime.
Optimized for Low-Pressure Systems
The LPT Turbocharger is a low-cost energy recovery solution that’s ideal for low-pressure systems. Like our AT Turbochargers, the LPT line offers high-efficiency, long-term reliability and versatility in a compact footprint.
Designed for low-pressure applications such as multi-stage brackish reverse osmosis water treatment, this device handles flows from 6.8 to 908 m3/h (30 to 4,000 gpm) and pressures up to 45 bar (650 psi). The LPT is the ideal solution for two-stage systems where flux balancing and system optimization are desired. It can easily replace a booster pump for this service, providing equal or better performance all while requiring no electrical connections, motors or drives.

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.
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.
