Swimming pool electrolyzer using in swimming pool, cooling water system, fire water system, fresh water and other water cleaning plants. Swimming pool: when we pass mildly salted (3 to 4 gram per litter - which is 90% less salty than normal seawater) pool water through the electrolyzer, the salt is converted in to chlorine which disinfects it and kills any algae and bacteria. The water in the swimming pool becomes silky soft to the skin, no slat taste & kind to your hair. The process operates continuously whilst the filtration system is in action, cleansing the water thoroughly without the need for extra additives.
