A salt chlorinator is a device that is used to sanitize swimming pool water using electrolysis.

The process involves passing a small electrical current through a saline solution, which generates chlorine gas that is then dissolved in the pool water.

The resulting solution is a weak form of hypochlorous acid, which is an effective disinfectant that can kill bacteria and other microorganisms in the water.

Salt chlorinators are an alternative to using liquid or solid chlorine as a sanitizer, and they are often preferred because they are easier to use and require less maintenance.
