In the south mediterranean countries and especially the NorthAfrica, the water demands, since many decades, have increased while the conventional water availability has decreased dramatically. These trends continue. The obligation to use other non conventional water resources such as desalinating water or waste water reuse becomes a necessity. The desalination of various synthetic brackish waters by reverse osmosis was conduced using an industrial pilot plant. The influence on the desalination performances of many runing parameters such as pressure, recovery rate and salinitywas studied. The performances of three commercialmembranes in salt rejection were compared.
