Desalination of Seawater Helps Meet Fresh Water Demand

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.

Remote Water Treatment Process System Benefits

Conventional water treatment control systems often lack the ability to communicate all process parameters from a centralized location to the point of operation. Thus, standardized control of all the facilities within a water district is difficult. Process adjustments performed onsite may not conform to federal, state or municipal regulations for water quality control.
