Three French companies are meeting the water demands of large populations through the use of seawater desalination.Distillation and reverse osmosis are two competing techniques in the desalination of seawater. While each method has pros and cons, both provide a vital service in making seawater drinkable. Three French water companies (Saur, Degremont and Sidem) are working to improve the quality of fresh water created by both these methods and have invested heavily in the Mediterranean and Middle East markets with these technologies.
