Chlorine dioxide disinfectant: The invisible guardian protecting bottled water safety

02 - Apr - 2026

In today's fast-paced life, bottled water, with its convenience and hygiene, has become the mainstream drinking water choice for homes and offices. From everyday drinking water to the base for tea and coffee , bottled water has been a constant companion. With the official implementation of the new "Technical Specifications for the Production of Prepackaged Drinking Water" in 2026, stricter disinfection standards have been imposed on every stage of bottled water production, making drinking water safety a focus of public attention once again . Chlorine dioxide disinfectant perfectly meets these new regulations , playing a crucial role in the disinfection process throughout the entire bottled water production process , making it an important choice for safeguarding the safety of bottled water quality. Today, we'll discuss how to use scientific disinfection solutions to protect the purity of drinking water .

I. New Safety Challenges for Bottled Water Under the New Regulations

The new regulations have raised the bar for hygiene standards and disinfection processes in drinking water production, posing new challenges to the disinfection process in bottled water production. Among the many disinfection technologies available, chlorine dioxide has become the preferred choice for bottled water production due to its unique advantages of effectiveness and safety. Its industry-favored disinfection method stems from several key characteristics: as a strong oxidant, chlorine dioxide can rapidly kill harmful microorganisms in water, with a bactericidal effect far superior to traditional chlorine agents, and it does not produce carcinogenic trihalomethanes or other byproducts; the decomposition products after disinfection are only trace amounts of salt and water, which are non-toxic and harmless, posing no threat to human health and not affecting the taste or quality of the bottled water itself; at the same time, its application range is extremely wide, from raw water purification to the refined disinfection of water barrels and bottle caps, and to the comprehensive cleaning of the production environment, all demonstrating excellent disinfection effects and truly achieving safety assurance throughout the entire bottled water production chain.

an excellent choice for disinfecting bottled water ?

1. Effective broad-spectrum bactericidal effect

Chlorine dioxide ( ClO₂ ) is a strong oxidant that can quickly kill harmful microorganisms in water, such as E. coli, viruses, algae, and insect eggs. Its bactericidal effect far exceeds that of traditional chlorine preparations, and it does not produce carcinogenic trihalomethanes or other byproducts.

2. Safe and residue-free

After chlorine dioxide is disinfected, the decomposition products are only trace amounts of salt and water, which are non-toxic and harmless, and will not pose any threat to human health, nor will they affect the taste and quality of bottled water.

3. Wide range of applications

From the purification of raw water to the disinfection of water buckets and bottle caps, and the comprehensive cleaning of the production environment, chlorine dioxide plays an excellent role in ensuring the safety of the entire bottled water production chain .

43 years of experience in the disinfection field , Xiuba chlorine dioxide has accumulated rich experience in the entire process of disinfection in bottled water production. From disinfection of packaging materials such as water buckets and bottle caps, to algae removal in raw water, disinfection of the production environment, and hygiene protection for operators, Xiuba chlorine dioxide can be applied to all scenarios . Behind this is 43 years of in-depth cultivation of disinfection technology, the support of an annual production capacity of tens of thousands of tons, and the support of 35 patented technologies, including 9 invention patents and 26 utility model patents, which continuously optimize the product in terms of disinfection effect and ease of use.

In the core disinfection process of bottled water production, Xiuba chlorine dioxide 's application method meets the actual needs of different production lines. It is simple to operate, provides stable results, and complies with the 2026 revised technical specifications for pre-packaged drinking water production.

For large-scale production lines equipped with spray disinfection devices, 200 mg/L of Xiuba chlorine dioxide disinfectant can be added to the disinfectant preparation tank and sprayed into the water tank through the nozzle. After rinsing, the water can be directly filled, which is highly efficient and suitable for assembly line operations. For small production lines without disinfection devices or bottled water production lines, the water tanks can be soaked in an 80-150 mg/L Xiuba chlorine dioxide disinfection tank for 10-30 minutes and then rinsed with sterile water to achieve thorough disinfection. For raw water disinfection and algae removal, add 0.2-1 mg/L of Xiuba chlorine dioxide disinfectant solution according to the water quality , and let it act for more than 30 minutes to effectively remove algae and improve water clarity. For the air, floors, and equipment in the production workshop, spray or wipe with 100 mg/L disinfectant solution. Concentrations of 2000 mg/L and above can also be used for air fumigation to create a sterile production environment in all aspects. Soak the hands of operators in 30-100 mg/L disinfectant solution, and use 200 mg/L disinfectant solution in the shoe and boot pool to avoid human contamination from the details.

Xiuba chlorine dioxide has become the preferred choice for bottled water disinfection not only because it aligns with industry usage plans, but also because of its strong professional qualifications and technical backing. Its core R&D team participated in the drafting and revision of national standards such as "Stable Chlorine Dioxide Solution (GBT 20783-2023)," possessing the most professional control over the technical parameters and industry application standards of chlorine dioxide. Its developed effervescent disinfectant tablets and activation-free high-purity disinfectant solutions are among the best in the industry in terms of activation rate, disintegration speed, and stability. Furthermore, the products have passed multiple authoritative certifications, including ISO9001 quality management system and ISO14001 environmental management system, and possess complete qualifications such as water-related permits and third-party inspection reports, meeting all national drinking water disinfection standards . Their quality and safety have undergone multiple tests.

In practical applications, Xiuba chlorine dioxide has served many different companies , from water supply projects for water plants (supporting water plants for the South-to-North Water Diversion Project) to packaged drinking water production bases across the country . For many years, Xiuba chlorine dioxide has become a reliable choice for disinfection in the bottled water industry due to its stable disinfection effect and comprehensive product system. This success is underpinned by its commitment to "authenticity, safety, and effectiveness," as well as the positive reputation built upon actual user experience.
