Abstract: To produce freshwater from a surface water located in Middle Atlas of Morocco, reverse osmosis process is used. This surface water has variable quality depending on the seasons, and its average chloride content is about 295 mg/L. The questioning of water quality variation over the seasons, initiated to make several simulations of reverse osmosis system design with two different water qualities. The first quality is characterised by a conductivity of 1,230 μS/cm recorded in winter and the second one is characterised by a conductivity equal to 3,013 μS/cm recorded in summer. The results of those simulations shown a better recovery rate compared with what was initially expected; 88% for the first less salty quality versus 78% for the second quality which was taken into account for the reverse osmosis plant design. This is also reflected in the energy consumption that decreased by 0.09 kWh/m3.
