Study of high efficiency membrane pilot test for membrane design optimisation in order to reduce the electrical consumption

Abstract

Regarding the studies of other authors about energy performance of a reverse osmosis desalination plant operating with variable pressure; about desalination efficiency in their different recent articles, we continued working in this way researching in a real seawater reverse osmosis plant following the items below. The objectives of this test are to get the minimum electrical consumption and energy costs for the operation of a sea water desalination plant using membranes. We need to compare the performance of the different membranes manufacturer’s and to determine, under this new thermal scenario, the optimal configuration to get the water quality and quantity needs with the minimum energy consumption.
