Impact Environnemental sur l’Etude Physico-chimique Durant les Etapes de Traitement de Sable (ADWAN, Mostaganem)

Abstract

Algeria experienced an economic development and demographic without precedent. The high rate of increase in population generated a which gallop urbanization and a not controlled growth of industry. That was not done without consequence on the environment. So the country faces today many problems involved in industry and the environmental protection and in particular the problem of small industries like the case of unit ADWAN, for the treatment of sand, where this last to undergo with one seriated of treatment (washing, drying, sifting, crushing), to obtain a product to call ’’the silica flour”, necessary for several sectors of industry, such as glass, and ceramic industries… etc Thus our work comes to know the environmental impact lasting this treatment, by making a physicochemical study on each stage.
