The technologies used in water desalination are accompanied by adverse environmental effects. There are several effects to be considered in desalination plants, such as the use of the land, the groundwater, the marine environment and noise pollution. Seawater desalination plants are located by the shoreline, to supply desalted water to the population of the main cities and for other uses. The construction of both the desalination plants and all the required infrastructure in coastal areas affects the local environment. For instance, the high salt concentration in the brine and several chemical products used in the desalination process are returned to the sea. Most impacts on the marine environment arise as a consequence of the brine discharge. In this paper, the objective of this work consists to study the dispersion of the brine discharges and its impact into marine environment. Then, a pilot used to study the different parameters of dispersion such as position of brine and depth and time of dispersion. Different points of brine (P1, P2, P3) were studied horizontally and vertically according to the ambient sea water. Experimental results obtained show that dispersion of brine in best then position of brine point is far and in down sea (P3).
