Purpose. To optimize the phenomenon of salt crystallization at Merouane Chott (Algeria) by solar energy using mirror reflection of solar radiation.

Methodology. In this work, experimental studies were carried using test facilities for evaporating brine equipped with a mirror and installed near the Merouane Chott. The test results were compared to the data obtained while applying the same facilities, yet without a mirror.

Findings. According to the test results obtained using test facilities with a mirror, the evaporation rate and the crystallization thickness of the salt are very significant compared to the control pan, probably due to the surface of the reflecting mirror; the time of crystallization of the brine by solar energy is proportional to the dimensioning of the mirrors.

Originality. The study site of the Merouane Chott is located in the region of El Oued (South East of Algeria) which is characterized by an intense solar flux. To benefit from this renewable energy source, a flat mirror was installed to accelerate the salt crystallization process and optimize the residence time of salt brine by natural evaporation.

Practical value. The optimization of the salt crystallization process by solar energy with the use of plane mirrors installed on the salt pans and the presence of a favorable organic environment present sources of sustainable development assets of the salt industry based on its evaporation driven by solar energy, as well as the development of a region rich in fauna, flora and geo-tourism.
