Millions of people around the world enjoy swimming pools every year. The traditional method is to use chlorinated chemicals to produce hypochlorous acid for disinfection. At present, a new industrial technology of hypochlorous acid production, chlor-alkali process has been applied. According to this method, an electric current is passed through an electrolytic cell containing a solution of sodium chloride (NaCl). The anode generates chlorine (Cl-) ions, and the cathode generates hydroxide (OH+) ions. Like traditional chlorinated chemicals, this method can also produce chlorine gas. The electrolytic 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 bleaching damage to bathing suits, and because it is the use of soft water, the system can also greatly reduce the irritation effect on the skin. The ruthenium-iridium titanium coated insoluble titanium anode provided by Kaida can be used as a swimming pool water electrolysis chlorine disinfection device. 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 bonded to the substrate, and has a long service life. Another unique advantage of Kaida in titanium anode is that the precursor material of the coating belongs to our own technical achievements, combined with international standard titanium substrate processing means and advanced coating technology, so that the product has a higher cost performance.
