Reverse osmosis is a highly efficient and less energy demanding process for separation of salts and other pollutants from water. A durable and flexible membrane developed by the researchers led the desalination industry to apply reverse osmosis on a massive scale. Today major desalination facilities in Israel and around the world are based on this development. The second reverse osmosis desalination facility in the world based on this method was constructed by prof. Loeb at Kibbutz Yotvata at 1968.
