Abstract
An energy recovery device has an important role in reducing specific energy consumption in seawater reverse osmosis desalination process. A next–generation isobaric energy recovery device (ERD) has been developed under the Mega–ton Water System Project. The device achieved 2% higher energy recovery effectiveness and low volumetric mixing without over–flush compared to the conventional ERD. The design concept and its characteristic feature of the next–generation ERD is presented together with the results of experimental validation and numerical computations.
