Drinking water disinfection is extremely challenging, as not all water qualities can be easily controlled with disinfectants. China's diverse topography means that many northern cities and areas with limestone formations generally have high water hardness. Due to these regional differences, conventional water treatment and disinfection processes are often insufficient for these specific water bodies, leading to rapid changes in disinfection attenuation rates and significantly reduced disinfection effectiveness.

Why can't ordinary chlorine dioxide processes directly disinfect hard water to meet standards?

Hard water has a high calcium and magnesium content, which directly affects the activation efficiency and stability of chlorine dioxide disinfection.

Ordinary chlorine dioxide disinfection faces two major challenges:

Firstly, in hard water, the factors that cause chlorine dioxide to lose its activity mainly come from alkaline substances and metal ions in the water. Chlorine dioxide directly reacts with iron, manganese, and organic matter in the water. If the concentration of iron and manganese is too high, it will directly affect the rapid consumption of the effective chlorine concentration, and thus become less effective in eliminating organic matter.

Secondly, the chlorine dioxide disinfectant after cremation, due to long-distance pipeline transportation, will be affected by the high ionic strength of hard water, causing the residual chlorine in the terminal water to be almost completely consumed, making it difficult to achieve the ideal value for terminal secondary water supply.

While chlorine dioxide disinfection does have limitations to some extent, the actual technical solutions also involve differences between products. Its presence determines the quality of disinfection, which is where the control capability of stable, slow-release chlorine dioxide technology lies. This is where Xiuba's technological barrier lies, enabling it to handle various complex water bodies.

Erxiuba's slow-release technology redefines cost-effectiveness with stabilized chlorine dioxide disinfectant.

All Xiuba series products are developed using exclusive scientific research technology and have mature industrial production capabilities. They possess over 20 years of leading expertise in product stability and buffering technology. In its technological development for the drinking water sector, Xiuba products ensure a significantly lower decay rate for chlorine dioxide disinfectant, guaranteeing a disinfection effect that is a fraction of that of ordinary products under the same dosing conditions.

One typical data point clearly demonstrates this advantage: to achieve a terminal residual chlorine level of 0.3 mg/L, the initial dosage is only about 0.35 mg/L, which is far lower than the initial value of 0.6 mg/L for general chlorine dioxide disinfection products.

Hard water tests not only the decay rate but also, and more importantly, the ability to maintain disinfection capabilities. Xiuba chlorine dioxide meets these requirements, demonstrating direct killing effects against E. coli and Staphylococcus aureus without leaving residue. Furthermore, due to its high stability, Xiuba chlorine dioxide produces virtually no chloroform, carbon tetrachloride, or other special byproducts, effectively ensuring the safety and reliability of disinfection treatment during long-distance transportation.

Considering the overall cost of the disinfectant, effective control of the decay rate of Xiuba chlorine dioxide disinfectant means it has a higher comprehensive utilization value. Low dosage means low risk, no byproducts, and no issue of reduced disinfection effectiveness. Achieving a lower total input within the effective range is a unique cost-effectiveness advantage.

In addition to pharmaceuticals, our intelligent system offers a wide range of supporting applications.

Of course, there are still more differentiated disinfection properties when it comes to hard water. Therefore, considering the complexity of water quality, Xiuba has fully developed products to match different types and provide disinfection application products for more diverse water quality needs.

One type is Xiuba binary/univalent chlorine dioxide powder, specially designed for large-scale water plants. It features a binary packaging design (A/B agents) for on-site activation and more thorough release of active ingredients. The other type is Xiuba chlorine dioxide effervescent tablets, which solve the problem of uneven secondary water supply ratios. They allow for direct, precise dosage, easily addressing the challenge of hard water disintegration.

In addition to disinfection products, we also equip businesses with safer and more precisely modulated chlorine dioxide generators, enabling fully automated and stable operation through precise dosage control. Even with fluctuations in hard water, it has the ability to autonomously adjust the activation time, ensuring the agent is always in ideal working condition, eliminating concerns about frequent dosing and increased costs due to rapid degradation.

In the context of high-quality development of drinking water, Xiuba has gone through nearly 40 years of trials and tribulations, and every step it has taken has been based on product quality. This focus on technological upgrades with low loss and high returns has given Xiuba extraordinary product strength.

Xiuba conveys this commitment to all the companies it serves through its products. While supporting their production and development, Xiuba also reinforces its unwavering commitment to winning the market through quality. Xiuba is not just selling chlorine dioxide; it is continuously achieving breakthroughs in chlorine dioxide technology to address China's water quality challenges, developing more innovative products, and ultimately enabling more cities to enjoy unrestricted access to safe drinking water.
