DESALINATION PLANTS SEARCH GOOD QUALITY RAW WATER.

Surprising, but it is reality that desalination stations shut down during periods of flooding. Despite a very demanding pretreatment phase, RO does not accept seawater laden with dust. What can we do to get our stations to agree to desalinate sea water and provide drinking water for the population? However, watercourses quite simply fulfill nature's mission, that of dumping tons of solid particles into the sea annually to preserve and protect the marine ecosystem. This study showed that more than 50 rivers and several Chaabat (ravines) discharge approximately 120 million tons of fine particles annually into the Mediterranean Sea along the 1200 km Algerian coast. However, these fine materials should not enter the desalination process. For us, the choice of the location of the water intake for a seawater desalination plant must follow a serious study to ensure good quality raw water. This will reduce the cost of the pretreatment phase and increase the lifespan of the membranes for the reverse osmosis process. Obviously, without forgetting, the price of m3 of desalinated water will be less expensive. On the other hand, desalinating the brackish waters from the subsoil of the Sahara does not pose a problem with the quality of the raw water, but it does pose a problem with the temperature of the water in the deep water table, which exceeds 60°C. Only the cooling solution to reduce the temperature of the raw water to minus 30°C to be able to desalinate and obtain drinkable water, but at what cost? [ABSTRACT FROM AUTHOR]
