Abstract : The subject review concludes that present reverse osmosis (RO) technology cannot insure production of drinking water quality effluent in all instances, but that the technology may be improved by staging the RO units. This may be done by optimizing power cost and permeate water flux (objective functions) with the sole constraint that an arrangement effect 100 percent rejection of solute, The report also recommends searching for a better membrane than polyethylenimine (PEI) and continuation of the literature review to cover membrane fouling, disposal of concentrates, operation costs, and removal of bacteria, protozoa and viruses. The review finds that PEl is the best candidate membrane for optimization studies at this time.
