Impact of Desalination of Sea Water on a Coastal Environment of Chatt El Hillal (Beni Saf

Abstract

Around the Mediterranean coast, 79% of the production of fresh water is assured by reverse osmosis (SWRO). The great units are located in Spain, Israel and in Algeria, who chose the desalination of sea water as solution to solve the problems of drinking water shortage. Desalination thus will be essential like a resource alternative essential with the perenniality of great coastal cities where the need is felt. For to illustrate its strategic importance from now on it desalination became a vital need for great Algerian urban cities of the Mediterranean coastal such as Oran, Algiers, and Arzew. A number which the authorities aim to increase to 43 by 2019 but much of questions is currently posed on the impact of these installations on the environment. The principal environmental impact associated the processes of desalination comes from the production of the brine (salt concentrations maximum 36375mg/l). The other environmental impacts are: problems of landscape degradation, harmful effects sound, the emission of gas, or discharges associated like water coming from cleaning with the filter.
