Titanium anode specification shape and coating performance requirements can be processed according to customer needs. Chlorine dioxide disinfection method has the following advantages: (1) It can reduce the formation of chlorination by-products such as trihalomethane in water; (2) When the ammonia content in water is high, it does not react with ammonia, so its oxidation and disinfection effects are not affected; (3) It can kill pathogenic microorganism and virus in water; (4) The disinfection effect was not affected by the value of water; (5) After chlorine dioxide treatment, the residual chlorine in water is stable and durable, and has strong ability to prevent re pollution; (6) Due to strong oxidation, it can remove the color and taste of water, and does not form chloronol odor with nol; (7) The removal efficiency of iron and manganese is better than that of chlorine.
