Has it ever happened that when you get up early in the morning, you turn on the tap and the clear tap water rushes out. It seems very common, but in fact, there is a lot of knowledge in it. Tap water is the lifeblood of city life. Its safety is related to the health of each of us. In the past, waterworks used to disinfect with chlorine. Although this method worked well, the small carcinogenic monsters and the unpleasant smell left after disinfection were like invisible killers hidden in the water, which made people uneasy.

At present, the disinfection industry has welcomed a new favorite - chlorine dioxide (clo‹), which has been rated as the top safe disinfectant of class A1 by the World Health Organization (who), and is known as the star in the field of water treatment in the 21st century. What makes it so popular? Go directly to the key dry goods. Xiuba Xiaobian will analyze the five key advantages of chlorine dioxide in detail. 

1、 High sterilization efficiency: broad spectrum, low concentration, natural enemies of microorganisms

In the field of disinfection, germicidal efficacy is the key to measure strength. Chlorine dioxide is famous for its excellent sterilization ability. It easily surpasses the traditional chlorine through its unique oxidation. It is like a superhero in the micro world. It can accurately penetrate the cell wall of microorganisms, hit the key points, destroy the enzyme system containing sulfhydryl groups, and lead to the metabolic dysfunction of microorganisms; At the same time, it can rapidly oxidize and decompose microbial proteins, fundamentally inhibiting their growth and reproduction.

What is more amazing is that chlorine dioxide only needs a very low concentration to show its power. It only needs 0.1-0.5 mg/l to destroy bacteria, viruses, spores, algae, etc. in a short time. Even Cryptosporidium and cyanobacteria, which are difficult to deal with by traditional disinfectants, are difficult to escape their power. According to authoritative experimental data, the inactivation rate of E. coli, Vibrio cholerae, poliovirus and other pathogenic microorganisms is as high as 99.9%, and the disinfection effect is lasting. After chlorine dioxide was used in a water plant, the detection rate of E. coli in the end water of the pipe network dropped from 1.2% to 0.01%, which is enough to show that the safety of water quality has been significantly improved. 

2、 Water quality safety: few by-products, health care

We are well aware that traditional chlorine disinfection is like a double-edged sword. At the same time of disinfection, it will react with organics in the water to produce strong carcinogens such as trihalomethanes and chlorophenols, which pose a threat to health. However, chlorine dioxide chooses a different path, through direct oxidation, almost no harmful by-products are produced, which is known as the "pioneer of green disinfection". The data is the best proof: after using chlorine dioxide, chloroform (chloroform) is reduced by 97%, carbon tetrachloride is reduced by 89%, and the risk of cancer is greatly reduced. 

In addition to avoiding harmful by-products, chlorine dioxide can also purify water in multiple ways. It can oxidize and decompose iron and manganese ions to solve the yellow water problem of residents; Remove sulfide and phenolic substances, and eliminate unpleasant bleaching powder taste; Decompose humic acid and other chromogenic substances to make tap water clear. Community residents who use chlorine dioxide have praised one after another: "the water quality is cleaner, the kettle is no longer scaling, and drinking is more reassuring."

3、 Strong stability: anti-interference, long-term protection, loyal guardian of the pipe network

Tap water from the water plant to the user's home needs to go through a long pipeline transportation, which puts forward high requirements for the stability of disinfectants. Chlorine dioxide still performs well in complex water quality due to its excellent pressure resistance. Its pH range is very wide. In the range of ph4-10, the sterilization effect is always stable, without additional adjustment of pH, which greatly simplifies the operation process. Moreover, regardless of the severe cold and heat, the temperature change has little impact on its disinfection efficiency, and it can be called an all-weather guardian. 

According to China's sanitary standard for drinking water, the residual chlorine dioxide in the factory water is ≥ 0.1 mg/l, and the end of the pipe network is ≥ 0.02mg/l. Like a loyal guardian, these residual chlorine can inhibit the growth of microorganisms in the pipeline for a long time, effectively prevent secondary pollution, and ensure that every drop of water in residents' homes is safe and reliable. 

4、 Multi functional purification: eighteen kinds of martial arts to create high-quality water quality

Chlorine dioxide is not only excellent in disinfection, but also an all-round player in the field of water treatment. It can inhibit the formation of biofilm, destroy the microbial membrane on the inner wall of the pipeline, and prevent the occurrence of "black water" and "red water"; It can also reduce cyanide and sulfide to harmless substances, reduce the toxicity of heavy metals, and add another layer of protection for water quality safety; In terms of decolorization of industrial sewage, it also performed well, and the efficiency was increased by more than 30%. Chlorine dioxide was used to treat cyanide containing wastewater in a chemical industry park, and the cyanide removal rate was as high as 99.5%, which successfully passed the environmental protection acceptance. This shows the strength of chlorine dioxide. 

5、 Safety and environmental protection: comprehensive guarantee and worry free choice

The safety of chlorine dioxide has been certified by international authorities. The World Health Organization (who) has confirmed that its trace residues are harmless to health, so as to ensure that people can drink it safely. In the field of environmental protection, it is also outstanding. Its decomposition products are only chloride ions and a very small amount of chlorite, which has far less impact on the environment than chlorine disinfection. It can be called an "eco-friendly" disinfectant.

In daily use, the safe operation of chlorine dioxide is also reassuring. The on-site preparation technology has been mature. The dosing device with intelligent monitoring function can strictly quantify the dosing capacity and cleanliness, and intelligently monitor the concentration in real time to prevent excessive use, providing a double guarantee for the disinfection of tap water.

From efficient sterilization to environmental protection and safety, each advantage of chlorine dioxide directly attacks the shortcomings of traditional disinfection methods, and builds a solid barrier for our water safety. Looking into the future, it is believed that the emerging forces in this disinfection field will enter more water treatment plants to provide safer and better drinking water for countless families.
