    2016-12-1 · To produce high purity water with RO, UPW production system often adopts two-pass RO where the permeate of the first-pass RO process is filtered by the second-pass RO , (Fig. 7a). Two-pass RO aims for a low level of impurity with additional membrane barrier, different from two-stage RO process which was suggested for a high recovery rate.
