Many people install salt water systems under the impression that it is chlorine free. Salt water systems produce chlorine electronically and therefore does not require adding chlorine to the water physically. So salt water is not chlorine free water. There are alternative pool sanitation systems that use an advanced oxidation process, combined with copper ionization to sanitize the water. These oxygen based systems do not produce any chlorine. These systems produce 100% chlorine free water.
Chlorine is used in the process of cleaning water before its available for human consumption. It kills the bacteria in the water that can cause diseases.
