Introduction to the use, specification and structure of sodium hypochlorite generator
Sodium hypochlorite generator is the equipment for producing sodium hypochlorite by electrolysis of low concentration chlorine solution on site, which is commonly used in the disinfection and sterilization of bacterial wastewater in hospitals and the treatment of cyanide-containing wastewater in electroplating, and also can be used in the oxidation treatment of other organic wastewater, and the disinfection of small-scale water supply projects where chlorine source (liquid chlorine and bleaching powder) is difficult to be used. Its models and types are very many, different models and types of sodium hypochlorite generator structure is not the same, in this paper, we will choose a few typical sodium hypochlorite generator to do the introduction.

Manufacturing process and use of industrial hydrochloric acid
Industrial hydrochloric acid is usually made by letting chlorine and hydrogen undergo a chemical reaction in corrosion-treated cylinders to produce hydrogen chloride, which is then injected into water. Because the chemical reaction will produce some iron trichloride part of the impurities.
Outstanding Advantages and Detailed Uses of Sodium Hypochlorite Disinfection Solution
Sodium hypochlorite disinfectant has the following outstanding advantages compared with other disinfectants: I. Pure quality The use of edible salt and water as raw materials, no impurities and other substances Disinfection effect is precise, efficient and fast 1. chlorine disinfectant, is a highly effective chemical disinfectant. 2-10 minutes to kill a variety of microorganisms, including bacterial spores and fungal spores, can inactivate all viruses; can effectively prevent hepatitis, venereal disease, dysentery, cholera, typhoid fever and other diseases. 2. Low effective concentration. At the concentration of 5ppm, it has the exact disinfection effect. Safety and environmental protection 1.The effective chlorine content of the disinfectant solution produced by sodium hypochlorite disinfectant generator is from 1200ppm to 5000ppm.The concentration range of sodium hypochlorite solution is enough for disinfection, but safe enough for users. 2. Sodium hypochlorite disinfectant solution is highly efficient, high speed, broad spectrum, non-toxic, harmless, and free from residue contamination. 3. Sodium hypochlorite disinfectant is relatively stable, but it is very easy to decompose when it meets water, heat and light. It can be decomposed rapidly after disinfection and has no harm to the environment. 4. There is no free chlorine in sodium hypochlorite disinfectant, and it will not react with other organic substances to form a class of carcinogenic chlorinated organic compounds such as trichloromethane, carbon tetrachloride, dioxin. Fourth, comprehensive disinfection Sodium hypochlorite disinfectant can be widely used in five aspects, including human health care, such as clothing, food, housing, and so on, because of its pure quality and precise effect. Wide range of uses Sodium hypochlorite disinfectant also has the degradation of pesticide residues, anti-itching, cleaning, bleaching, deodorizing, antiseptic, preservation of freshness, prevention of mosquitoes and flies breeding and other aspects. Sodium hypochlorite disinfectant solution detailed use: Family: Can be used in all aspects of the family, can be in contact with water most of the items of the disinfection treatment.
