What are the differences between sodium hypochlorite generator and other disinfection equipment

At present, many new waterworks uniformly use sodium hypochlorite generators to disinfect tap water, and many old waterworks replace other existing disinfection equipment with sodium hypochlorite generators when upgrading equipment. Why do so many waterworks choose sodium hypochlorite generator? What is the difference between sodium hypochlorite generator and other disinfection equipment?
Although the sodium hypochlorite disinfection technology has been very mature, the use of sodium hypochlorite generator to disinfect tap water in China is still in the promotion stage. Before that, many waterworks used liquid chlorine or chlorine dioxide generators to prepare and disinfect on site. Compared with the two, the sodium hypochlorite generator has the following advantages:
1. The purchase of raw materials for liquid chlorine and chlorine dioxide generators is complex, and liquid chlorine, sodium chlorate and hydrochloric acid are hazardous chemicals, which pose risks in transportation and storage. Therefore, many people use sodium hypochlorite generators to prepare chemicals on site for disinfection.
2. The raw materials used in the sodium hypochlorite generator are salt and electricity. The sodium hypochlorite solution produced is a strong oxidant, which can kill all kinds of organisms and bacteria in the water without chemical reaction with other substances in the water. The treatment safety is far greater than other types of equipment.
3. Compared with other types of disinfection methods, the only disadvantage of sodium hypochlorite generator is its high operating cost. In addition to the high operating costs, there are no other shortcomings.
At present, sodium hypochlorite disinfection method has been widely used abroad. With the increasingly strict control of chemicals in China, the operation cost of other disinfection methods will become higher and higher. At this time, it is appropriate to use sodium hypochlorite generator to replace other disinfection equipment.
