Abstract

The present invention discloses a technique to enhance the efficiency of a pure water production by reverse osmosis (RO), which includes introducing a RO concentrate to an electrodialysis unit, so that a dilute water having a reduced electric conductivity is recovered and recycled to the RO unit as a portion of its feeding water.
