Energy Recovery Devices

Global demand for clean water continues to accelerate. Safe, reliable and cost-effective desalination solutions are increasingly important to many communities. The energy-efficient and scalable design of the seawater reverse osmosis (SWRO) process makes it the leading choice for municipal and commercial water supply. Flowserve offers you energy recovery solutions that are among the most efficient and reliable in the world.

Energy is generally the biggest cost driver in any SWRO desalination facility, thereby making energy recovery equipment critical to the process. Flowserve is a world leader in the manufacture and supply of the most efficient energy recovery devices for the SWRO desalination process. Through its Calder™ brand, Flowserve offers two types of energy recovery technologies: isobaric devices and energy recovery turbines. Together they have more than 30 years of experience and have recovered more than 750 MW of energy.

In addition to minimizing your current power usage, both of these technologies help minimize the impact of future energy cost increases.

Centrifugal Devices

Flowserve energy recovery turbines are designed and manufactured specifically for reverse osmosis desalination. They can recover the hydraulic energy stored in the brine stream, converting it into rotary power for the high-pressure pumps. Based on Pelton turbine design, Flowserve ERTs are highly efficient and reliable. They have been installed in nearly 1000 SWRO and BWRO plants worldwide, with a total installed capacity in excess of 350 MW.
