Definition of desalination

Water desalination is the process of converting salt water into pure fresh water, suitable for drinking and daily use, so that it is purified from salts that are used and benefited by the person. The process of desalination of salt water is carried out through many methods used in the desalination process, and it is a large series One of the processes to separate salts and minerals from salty water, which can be used by all people for multiple purposes and purposes, is resorting to conducting these processes to desalinate and purify water, especially in countries that are relatively poor in the amount of water they have.

The basic stages of water desalination are as follows

• Primary treatment of brackish water.
• Salts and minerals are removed from the salt water.
• Final treatment of brackish water.
• Factors related to the use of the proper method for desalination:
• Sea water quality and salt concentration in the water.
• Sea water temperature.
• Medical factors related to salt water.
• Determine the cost and the amount of expenditure spent on electricity and water.

Description of the brackish water desalination process

Salty water is collected from the sea for desalination and purification, special filters are placed to filter the water from impurities, salty water is placed in pumps, which pump salty water to the evaporators, sodium hydrochloride is put into the salty water, before pumping the salty water to the evaporators, to be Treating the salty water from the existing biological substances and impurities in relation to the salty water. Sodium hydrochloride solution is prepared in large tanks, and then added to the salty water. After that, all the salty water is transferred to the evaporators, so that this salty water goes through several processes and stages. So that the sea water evaporates through it, and the process of condensation of sea water occurs, and after that the water is collected, phosphates are added before obtaining fresh water, in order to prevent all impurities and scales from sedimentation, the salt water passes through special devices called (suckers air), in order to get rid of all the dissolved gases present in the salty sea water, the water is purified from salt, minerals and impurities, and the salt is also used.
