Desalination plants produce fresh drinking water from saline sources, such as sea water or underground brackish water reservoirs. The process typically involves several key stages: intake, where water is collected from the source; pre-treatment, which removes suspended solids and impurities; desalination, commonly through reverse osmosis or distillation, which separates salt and other minerals; and post-treatment, where the water is conditioned and disinfected to meet drinking water standards. The result is safe, high-quality potable water suitable for municipal, industrial, or agricultural use.
