Abstract: The reduction of energy consumption constitutes one of the major thrust areas of research in seawater reverse osmosis (SWRO) desalination plants. The cost of energy in the SWRO process is usually about 30–50% of the total production cost of water and can be as much as 75% of the operating cost, depending on the cost of electricity. Thus, energy forms the major contributing factor in determining the water production cost. Hence reducing the energy consumption, which is mainly due to wastage of energy in high-pressure brine, is a major goal of desalination industries.
