Flowserve is a world leader in the manufacture and supply of the most efficient energy recovery devices for the SWRO desalination process. Energy Recovery Devices for SWRO The DWEER Operating Principle Power recovery is independent of the high-pressure pump flow rate, so there is no critical best efficiency point with the DWEER. Because of its flat efficiency curve, the DWEER is able to operate efficiently under the varying range of flow and pressure found in any SWRO plant without adjustment. Energy is generally the biggest cost driver in any SWRO desalination facility, thereby making...

Energy Recovery Turbines Calder energy recovery turbines (ERT) are designed and manufactured specifically for reverse osmosis desalination. They can recover as much as 90% of the hydraulic energy remaining in the brine stream, converting it into rotary power for the high-pressure pumps. Highly efficient and reliable, Calder ERTs are installed in nearly 1000 seawater and brackish water reverse osmosis plants worldwide, with a total installed capacity in excess of 350 MW.
