Seawater desalination is unequivocally the future of drinking water production for coastal communities and island countries in the current time of water scarcity. It is already used a lot in a few countries. Saudi Arabia, the United Arab Emirates, and the United States are the top three desalination producers of drinking water by capacity in the world.
These countries benefit from desalination systems because they have a particularly dry climate with few freshwater resources, or because they need an expansion of water resources beyond their existing available water resources.
These seawater desalination systems are mostly used by coastal communities and offer a practically unlimited supply of nutrient water. Know some details about the applications of this seawater desalination technology.

The final goal of a desalination process is to remove the salts present in seawater that are concentrated at around 3–3.5%. There are also other ingredients in seawater that also need to be treated, such as color, silica, and microorganisms. To do this, the process begins by extracting ocean water through an inlet pump from a beach well or buried from an inlet pipe on the seabed. This water enters a leveling tank or basin. In this process, the water undergoes a pretreatment.
The pre-treatment usually consists of one or more filtration units that remove particles larger than 1 nanometer. This pre-treatment process is very important to reduce the risk of contamination of the RO membrane. In RO operation, the pressure is applied to overcome osmotic pressure. Therefore, water flows through the membrane to an area with a lower salt concentration, through which the salts flow to a concentrated solution (brine). The resulting clean water is subjected to an after-treatment process that includes remineralization and residual disinfection.
Finally, the produced brine concentrate is carefully discharged back into the ocean in a dispersing manner. This discharge process has been developed and designed to significantly reduce any negative impact on the local marine ecosystem. With the help of RO treatment systems for seawater desalination, coastal communities and island countries can achieve clean and safe water.
