High Quality Solar Salt Production: Process, Factors and Optimization

Abstract

Solar salt production is an ancient process in which seawater or brine is converted into crystalline sodium chloride by natural evaporation. Common salt contains undesirable impurities like sulphate, carbonates, silica / insoluble,etc.which make it unsuitable for industrial applications. High pure salt is essential for research work, developing new technologies, and producing advanced products. This paper discusses the process of solar salt production, the factors affecting its quality, and the use of digital and analytical tools to optimize the production process which can lead to production process improvement, increased production, improved brine management, which can help in providing high-quality products at low cost and relatively less labour.
