Have you ever thought about how much high-tech is hidden behind the water that flows out of the tap every morning? In the past, water plants loved to use chlorine for disinfection. Although it can kill bacteria, people always worry about whether they will drink some harmful substances - such as the pungent smell of chlorine and byproducts that may cause cancer.
However, now there is a new top-tier disinfectant in the disinfection industry - chlorine dioxide (ClO ₂ ) , which is rated as an A1-level top-level safe disinfectant by the World Health Organization (WHO) and can be called the "black technology" in the field of water treatment in the 21st century. How powerful is it? Today we will take a look at its five unique skills!
1. It has a very strong antibacterial effect, and microorganisms will cry for help when they see it.

Chlorine dioxide's sterilization ability can be called "the Thanos in the microscopic world". It can directly destroy the cell structure of bacteria and viruses, making them completely lose their combat effectiveness. What's more, it only needs ultra-low concentrations (0.1-0.5 mg/L) to deal with various pathogenic microorganisms, including those stubborn elements such as Cryptosporidium and cyanobacteria that traditional chlorine cannot deal with .
Experimental data show that its inactivation rate for E. coli, Vibrio cholerae, and polio virus is as high as 99.9% , and the disinfection effect is super long-lasting. After a water plant used chlorine dioxide, the detection rate of E. coli at the end of the pipe network plummeted from 1.2% to 0.01% , and the water quality safety was directly maximized!
2. Fewer by-products, safer to drink
Although traditional chlorine disinfection can kill bacteria, it will react with organic matter in the water to produce trihalomethanes, chlorophenols and other carcinogens. Who wouldn't be worried if they drank too much? Chlorine dioxide takes the "green route" and kills bacteria by direct oxidation , producing almost no harmful byproducts.
Data speaks for itself: After using chlorine dioxide, chloroform (trichloromethane) is reduced by 97%, carbon tetrachloride is reduced by 89% , and the risk of cancer is greatly reduced. It can also remove iron and manganese, remove sulfides, and decompose humic acid , making tap water clearer, and kettles no longer scaled, making it safer to drink!
3. Super stability, the "longevity warrior" in the pipe network
Tap water has to be transported through long pipelines from the water plant to the home, which places extremely high demands on the stability of the disinfectant. Chlorine dioxide can be called a "hexagonal warrior" in this regard:
Wide pH adaptability range (4-10) , no matter how extreme the acidity or alkalinity is
Resistant to high and low temperatures , stable performance in both summer and winter
The residual chlorine lasts for a long time , the factory water requirement is ≥0.1 mg/L, and the end of the pipe network is ≥0.02 mg/L, which can effectively prevent bacteria from growing in the pipes.
my country's "Sanitary Standards for Drinking Water" recognizes its stability. Using it for disinfection will make the water flowing out of your home tap safer!
4. Versatile and versatile in water purification

Chlorine dioxide is not only a sterilizer, it is also the "Swiss Army Knife" of water treatment:
Inhibit biofilm and prevent black mold and red water from growing in pipes
Decompose heavy metals and reduce the toxicity of cyanide and sulfide
Industrial wastewater decolorization , efficiency increased by more than 30%
A chemical park used it to treat cyanide-containing wastewater, with a cyanide removal rate of up to 99.5% , and it directly passed the environmental protection acceptance. This strength is unparalleled!
5. Safe and environmentally friendly, you can drink and discharge with peace of mind
The safety of chlorine dioxide has long been certified by the WHO. Trace amounts of residue are harmless to the human body , so there is no need to worry about drinking it. Moreover, after decomposition, it only produces chloride ions and a small amount of chlorite , which has much less impact on the environment than chlorine disinfection, and can be called an "environmental protection angel."
Many water plants now use smart dosing devices to accurately control the amount of chlorine dioxide used, which not only ensures the disinfection effect but also prevents overdose, providing double insurance!
Recommended product: Showba chlorine dioxide disinfectant
When it comes to chlorine dioxide products, we have to mention the brand Showa . It uses stabilization technology and is available in tablets, powders and other forms. It saves dosage and has strong effects. Moreover, it has a unique activation technology that can accurately release chlorine dioxide, with super high sterilization efficiency!
It has a wide range of applications, ranging from tap water, mineral water, food and beverages to sewage treatment . It is definitely an "all-round player" in the disinfection industry!
Summary : Chlorine dioxide is replacing traditional chlorine disinfection worldwide and becoming the "new favorite" of water plants due to its five unique features: high sterilization efficiency, few by-products, strong stability, comprehensive functions, and safety and environmental protection. In the future, it may enter more households and make our drinking water safer and healthier!
