Salt chlorination is a process through which common salt (sodium chloride) is added to the pool water and chlorine is separated from sodium. Through the chlorination of salt, chlorine is produced to disinfect the pool water.

The greatest advantage is economically, since with saline chlorinators there is a great saving in both maintenance and chemical products such as sodium hypochlorite and other compounds derived from chlorine. In addition, as the water is renewed every several years, the cost of the pool is reduced.
