Salt Water Chlorinators

Salt water chlorination, is a process that uses dissolved salt (2,500–6,000 ppm) as a store for the chlorination system.

In order to achieve this concentration, the chlorine generator (also known as salt cell, salt generator, salt chlorinator) uses electrolysis to break down approximately 200-500 pounds of salt (NaCl).

The resulting chemical reaction eventually produces hypochlorous acid (HCIO), and sodium hypochlorite (NaClO), which are the sanitizing agents already commonly used in swimming pools.

As such, a saltwater pool is not actually chlorine-free; it simply utilizes a chlorine generator instead of direct addition of chlorine.
