Urbanization has led to an increase in high-rise buildings, making secondary water supply systems a crucial guarantee for residents' daily water needs. As the "last mile" from municipal water supply to homes, the water quality of secondary water supply tanks directly impacts the health of countless households, requiring utmost care. However, these tanks are relatively enclosed storage facilities, and without regular cleaning and disinfection, bacteria and mold can easily proliferate, posing a potential threat to water quality. The quality of water supply in high-rise buildings hinges on the disinfection process of the secondary water supply tanks, with chlorine dioxide serving as a high-quality disinfectant for safeguarding water quality. Today, we'll discuss scientific cleaning and disinfection methods for secondary water supply tanks, ensuring safe drinking water for high-rise residents.
Secondary water supply tanks are the core of water supply in high-rise residential communities, primarily used to store municipal tap water before distributing it to individual households via pressurization equipment . According to national regulations, secondary water supply tanks must be cleaned and disinfected at least twice a year. If not cleaned for extended periods , bacteria , mold, and other harmful microorganisms can easily proliferate inside , causing water pollution. Regarding disinfectants, chlorine dioxide has become the mainstream choice for secondary water supply disinfection due to its safety, lack of residue, and effective disinfection properties. It can quickly kill harmful microorganisms in the tank, effectively remove odors from the water, and does not produce harmful disinfection byproducts, fully complying with relevant regulations for drinking water disinfection .
To effectively disinfect secondary water supply tanks, selecting an effective disinfectant is crucial, but using the correct method is equally important . Many chlorine dioxide disinfectant products are available on the market, among which Xiuba brand chlorine dioxide disinfectant, with its 43 years of technological research and development experience , has become the preferred choice for numerous water supply units . Chen Xiaoping, the technical director of its R&D team , also participated in the formulation of the national standard for "Stable Chlorine Dioxide Solutions" (GBT 20783-2023), demonstrating precise control over the technical parameters and industry standards for drinking water disinfection. The product's technology and quality have also undergone rigorous testing.
Professional Perspective: How to Scientifically Disinfect Secondary Water Supply Systems?
Based on practical application scenarios, Xiuba brand chlorine dioxide disinfectant has been designed with two practical usage schemes to meet the needs of secondary water supply tanks , adaptable to the water supply scale of different communities. For communities with large daily water supply, it can be used with a chlorine dioxide generator. This professional supporting equipment makes secondary water supply disinfection operations more intelligent and precise, adjusting the dosage of the disinfectant in real time according to the actual situation , resulting in more stable disinfection effects, and it is also very convenient to operate . For scenarios with smaller water consumption, such as independent buildings, Xiuba brand chlorine dioxide disinfectant can be used with a dosing pump, reducing investment costs while ensuring disinfection effects .
In terms of practical operation, Xiuba brand chlorine dioxide disinfectant is simple and easy to use , fully meeting the industry requirements for secondary water supply disinfection. Secondary water supply disinfection requires two key aspects: continuous water quality disinfection and regular facility cleaning. Only by addressing both aspects simultaneously can water safety be guaranteed .
Continuous water disinfection (dosing system)
For continuous water disinfection , these two dosing methods can be selected based on the layout of the community's water supply facilities :
After the disinfectant is fully mixed with water, it is pumped to the elevated water tank, which can simultaneously disinfect the water in the underground reservoir and the elevated water tank. The dosage of the disinfectant is controlled at 0.5-1 mg/L to achieve a comprehensive disinfection effect.
Setting the dosing point in the elevated water tank: This is for the final disinfection of drinking water that is about to enter the household. The dosage is relatively smaller, and a dosage of 0.2-0.8 mg/L can ensure the sterilization effect, effectively avoiding waste of the agent.
For regular cleaning of the water tank, Xiuba brand chlorine dioxide disinfectant powder can be diluted at a ratio of 1:50 to prepare a stock solution of 100-200 mg/L. Depending on the actual condition of the water tank, choose between soaking, wiping, or high-pressure spraying for disinfection . Soaking should last for at least one hour, while wiping or spraying should last for at least 30 minutes. One kilogram of disinfectant powder can treat a 100-square-meter water tank in ten minutes , ensuring effective disinfection while reasonably controlling usage costs.
