Introduction The increasing demand for hydrous resources makes more and more this food product divine rare, especially in the areas where these resources remain very limited, because of insufficient pluviometer to cover the needs for a socio-economical development. The region of Laayoune Sakia Hamra, in the south of Morocco, is characterized by its Saharian dry climate, suffers from these problematic. Which explain the recourse to the desalination of sea's water. This region which includes one of the biggest and the most important industrial areas in all the Saharian provinces, which is dedicated mainly to the treatment and the transformation of the products of the sea which makes an increasing requirement of water, all of this push them to the realize their own drillings, which generates a problem of intrusion of marine water, because of an overexploitation of subsoil water. Like the case of the liquid rejections of the industrial agglomeration which were poured directly through the sea without any treatment. All of that created a sort of an unbalance by the untreated wastes which involve pollution into the water of receiving environment (the sea). Everybody knows that the same region has bounds of famous coasts characterized by its outstanding halieutic wealth. The objective of this study is to evaluate the pollution's degree of the liquid rejections of the industrial area of ElMarsa Laayoune, across characterizations of various physico-chemical parameters. Then, a comparison of the results obtained to the standards prescribed by the followed regulation is carried out, in order to deduce the multy- possible processes of treatment for this type of rejection. The promising methods based on electrochemical technology as electrocoagulation, present a robust interest, if we can use a solar power like energy source. So the treatment of polluted water will be green and with a low cost effective method.
