“…In solution chemistry, saturation is the concentration at which a substance can no longer dissolve in a solvent (water in this case), the amount of salt recovered by the solar distillation system is 105 grams of salt per 3 liters of brine (this is the equivalent of 35 grams per liter). In countries with sufficient sunshine and temperature, such as Algeria, salt of rejected RO brine can be extracted by evaporation using a salt evaporation pond, and valuable salts could be obtained from brine for which there is great demand for several sectors such as agriculture, industry, environmental and others (Belhout et al 2018).…”

“…Currently, this brine causes substantial environmental problems because it has to be disposed of, which usually means it gets dumped back into the sea resulting in a region of hypersaline water that causes damage to fish and sea vegetation (Pérez-González et al 2012;Morillo et al 2014;Tong & Elimelech 2016;Heck et al 2018). The problem is even worse in applications far from the marine environment where the brine may be disposed of in deep wells or other sites, and again is a cause of environmental stress (Belhout et al 2018).…”

Disposal of rejected brine is a fundamental part of reverse osmosis desalination technology, it presents negative influences on the marine ecosystem, due to the high salt content and the presence of other harmful chemicals in the concentrate. Solar distillation is such a promising technology for brine management. The main goal of this study is to treat high salinity solution of reverse osmosis desalination brine and to recover valuable resources while producing freshwater. The implementation of the study is through two phases: the first phase includes desalination by reverse osmosis process to produce fresh water and the concentrated brine, while the second phase consists of recovering solid salts using the solar distillation. Thus, different experiments of desalination by reverse osmosis pilot and solar distillation were carried out under the optimal experimental conditions. The obtained results showed that Chlorides are the most dominant constituents in the composition of brines, while the daily water productivity contributed to around 80% of the total productivity of the solar system (volume of the water produced/m2/day) and the amount of salt crystallize by solar distillation represents 35 grams per liter of brine, this salt has a great demand for several sectors such as agriculture, industry, and others.
