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

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

Assessment of the Quality of Water Discharges from a Desalination Plant: Case of Honaine Station (Western Algeria)

Around the Mediterranean coast, 79% of the production of fresh water is assured by reverse osmosis (SWRO). T many desalination plants have emerged in Algeria, who chose the desalination of sea water as solution to solve the problems of drinking water shortage. The deficit in drinking water was important in western Algeria, which explains the high number of stations: Macta, Bousfer, Bouzedjar, Chatt el Hillal, Honaine et Ghazaouet. A number which the authorities aims to increase, but much of questions are currently posed on the impact of these installations on the environment.  It is in this context that a study has been carried out to determine the quality of the water discharges at sea, resulting from the desalination process. The principal environmental impact associated the processes of desalination comes from the production of the brine (salt concentrations betwin 36750 mg/l and 37800 mg/l). The other environmental impacts are: discharges associated like water coming from cleaning with the filter, harmful effects sound, the emission of gas, or problems of landscape degradation

Environmental Diagnosis of Coastal Wetlands and Analysis of Anthropogenic Activities: Case of the West Coast of Algeria

The Mediterranean basin is rich in wetlands of great ecological, social and economic value. Yet these important  natural assets have been considerably degraded or destroyed, mainly during the 20th century. The wetlands of western Algeria are characterized by massive urbanization. This anarchic urbanization leads to over exploitation of the natural environment. The installation of numerous residential, industrial and tourist complex sites is a complication that suffocates many recreational sites and degrades the coastal environment. This situation has created a spatial disruption of the entire ecosystem, causing physical and biological disturbances. It is in this context that our diagnosis is inscribed to better understand the stakes of human activities and the urban dynamics of the Algerian west coast. The diagnosis made it possible to highlight an intense anthropogenic activities, and an important industrial activities generating numerous damages to the coastal environment

Contribution to the Characterization of Peri-urban Natural Areas of Sidi Bel Abbes Town (Northwestern Algeria)

Peri-urban areas are very important in the geographical structure of the city, a boundary for urban sprawl, diversifying the territory and its landscape, creating continuity. These areas constituted a problem to geographers and statisticians who wished to assign them contours. The delimitation of peri-urban areas is indeed difficult and must combine geographic, urban, economic and human parameters that might render account of a movement that affects almost all areas. Our approach is a contribution to the use of simple and rapid decisions as a tool for the characterization of natural space in the suburban town of Sidi Bel Abbes. It is based on a diagnosis of the current situation in this municipality. The study allowed us to identify 106 natural areas in a suburban area of over 3969.36 hectares
