Déminéralisation des eaux saumâtre pour l'alimentation en eau potable.

Abstract

Due to the lack of rainfall, the world is suffering from a great shortage of potable water. The use of salt water deminiralization techniques that contain minerals (salinity from 1 to 10 g/L) is necessary in response to the shortage of fresh water in this region. One of the most important of these techniques is reverse osmosis. The origin of this salinity is geological, as a result of leaching and gypsum formations of Triassic evaporites that are present in the region through the exploited groundwater. The advantage of this type of deminiralization is the possibility of having non-traditional drinking water to meet the demands of local communities and contribute to the economic upgrade. The other aspect of this study is that Algeria has become one of the countries that relies heavily on desalination techniques because it contains huge quantities of groundwater, especially in the Algerian desert, which has become the owner of many plants to deminiralization salt water.
