Algeria, like other countries, faces water scarcity and has resorted to desalinating sea water to meet the needs of its population. The graduation project provides us with a reading of the various desalination processes, and provides updated information on the way the Bani Saf seawater desalination plant works. The proposed study aims to know the effect of pressure on the performance of the reverse osmosis system for desalination (flow density and retention rate)
