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...
