Abstract: A inventive two-stage batch-CCD RO system includes two separate batch-CCD units of a different number of modules per stage with more modules in the first-stage—N(1)>N(2). A two-stage batch-CCD process proceeds when both units execute parallel fixed flow variable pressure desalination sequences of same operational set-points [flux, module recovery and batch sequence recovery (R)], with brine of a former first-stage used as second-stage feed. In two-stage batch CCD RO systems of high N(1)/N(2) ratio whereby the relative production of permeates of the two stages complies to: ?(1)>>?(2), most of the permeates are produced in the first-stage under mild conditions and contribute to the low energy and salinity of permeates of the entire process. Compared with the performance of a single-stage batch-CCD RO unit, a two-stage system of the same module-number will render a performance of super RO characteristics, unmatched by any existing RO methods.
