Swimming pool disinfection
Anode for swimming pool disinfection
Millions of people around the world enjoy swimming in swimming pools every year. The traditional method is to use chlorine-containing chemicals to generate hypochlorous acid for disinfection. At present, a new industrial technology for the generation of hypochlorous acid, the chlor-alkali process, has begun to be applied. This method involves passing an electric current through an electrolytic cell containing a solution of sodium chloride (NaCl), producing chlorine (Cl-) ions at the anode and hydroxide (OH+) ions at the cathode. As with traditional chlorine-containing chemicals, this method Chlorine gas can also be generated. The electrolysis unit eventually produces substances including chloride ions, hydrogen ions and hypochlorous acid. The disinfection system using this salt chlorination system can effectively reduce the corrosion rate of swimming pool equipment and the bleaching and decolorizing damage to swimming suits, and because of the use of soft water, the system can also greatly reduce the irritation to the skin.
