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 to play a role in disinfection. At present, a new industrial technology for generating hypochlorous acid, the chlor-alkali process, is beginning to be applied. This method uses an electric current to pass through an electrolyzer containing a sodium chloride (NaCl) solution, and the anode generates chlorine (Cl^-) ions, and the cathode generates hydroxide (OH⁺) ions. Like traditional chlorine-containing chemicals, this method can also generate chlorine gas. The electrolytic unit eventually generates substances including chloride ions, hydrogen ions, and hypochlorous acid. The disinfection system using this salt-chlorinated system can effectively reduce the corrosion rate of swimming pool equipment and bleaching and decolorizing damage to swimming suits, and because it uses soft water, the system can also greatly reduce the irritation effect on the skin. The ruthenium, iridium and titanium coated insoluble titanium anode provided by Kaida can be used as a chlorine disinfection device for water electrolysis in swimming pools. The biggest advantage of this mixed oxide coated titanium anode (MMO) is that it can greatly improve the chlorine production efficiency, has excellent stability, and the coating is firmly combined with the substrate, resulting in a long service life. Another unique advantage of Kaida in titanium anode is that the precursor material of the coating is completely its own technical achievements. Combined with international standard titanium substrate processing methods and advanced coating technology, the product has a higher cost performance.
