  abstract =     "This study proposes a new operation methodology for
                 energy saving in the Fujairah seawater reverse osmosis
                 (SWRO) plant, as the optimum feed pressure is
                 determined at the controlled operating temperature. To
                 this end, two functional models were developed by
                 genetic programming (GP) using two-year operational
                 data. The data revealed that the required feed pressure
                 for the plant operation was potentially overestimated.
                 Based on the developed models, simulation of a
                 three-step sequential control was carried out to reduce
                 and optimise the required feed pressure. The simulation
                 results first indicate that the temperature control
                 significantly reduces the required feed pressure at a
                 reasonably high temperature. Second, as the permeate
                 water flow rate (PFR) is determined by the optimised
                 feed pressure instead of the permeate pressure actually
                 used to maintain a steady PFR in Fujairah, the required
                 feed pressure could be substantially reduced. As a
                 result, the proposed methodology can potentially reduce
                 the required feed pressure, by approximately 10 bar,
                 under the identical performance of both PFR and
                 permeate water total dissolved solids (TDS). This study
                 implies that the optimization of operation and
                 management of MSF-hybridized SWRO processes can
                 considerably improve the efficiency of the desalination
                 process in terms of energy and, eventually, cost
                 saving.",
