The suddenness of disasters and public health emergencies has made the construction of emergency response systems an increasingly important focus of public attention. From water pollution after floods and earthquakes to water supply security during sudden epidemics, drinking water, as a basic element for sustaining life, has always been a core component of emergency response systems. A comprehensive strategic material reserve system is a solid safeguard for drinking water security. Among various emergency water purification and disinfection supplies, chlorine dioxide, with its unique advantages of safety, stability , and strong adaptability, has become an important part of the national strategic material reserve. Chlorine dioxide products in the form of water purification tablets, in particular, have become an essential choice in emergency water supply scenarios due to their convenience, ease of storage, and ease of use .

In emergency situations, the demand for clean water is always prioritized for speed, but even more importantly, stability is paramount. Imagine after a flood, when drinking water sources are contaminated with silt and debris, and bacteria and viruses proliferate. Without convenient water purification methods, the safety of drinking water for affected people is nonexistent. During public health emergencies, drinking water in communities, schools, and centralized quarantine sites requires enhanced disinfection, and complex operating procedures simply cannot meet the needs of large-scale, high-frequency use. In scenarios such as wilderness rescue and geological exploration, workers rely entirely on temporary water sources, making portable water purification supplies an essential necessity . Traditional water purification methods either require specialized equipment and personnel, which are time-consuming and labor-intensive, or have limited disinfection effects and may leave residues, making them unsuitable for the diverse needs of emergency scenarios.
This is precisely why chlorine dioxide water purification tablets have become an important choice for strategic material reserves. As an internationally recognized A1-grade safe disinfectant, chlorine dioxide requires no complex activation and can quickly kill harmful microorganisms such as bacteria, viruses, and spores in water. It can also remove odors and degrade organic matter. Crucially, it does not produce carcinogenic byproducts such as trihalomethanes after disinfection, and its water purification effect meets national drinking water standards. The tablet form further enhances its advantages: small size and light weight, taking up little space for both warehouse storage and transportation; no professional skills are required for use—simply add it to water according to the ratio, let it stand for a moment, and it's ready to drink—even the elderly and children can use it easily; it is highly stable at room temperature and can be stored for a long time without its effectiveness being affected by prolonged storage, perfectly meeting the core requirements of strategic materials: "easy to store, easy to transport, and easy to use."

To better adapt Xiuba chlorine dioxide water purification tablets for emergency scenarios, the R&D team at Shandong Huashi Pharmaceutical has put in tremendous effort. Leveraging 35 patented technologies (9 invention patents and 26 utility model patents), and collaborating with universities such as Tongji University and Dalian University of Technology, they have continuously optimized the formula and process: resulting in higher activation rates and faster sterilization speeds, achieving 99.9% sterilization even at low concentrations; precise control of the effective ingredient content, requiring only a small amount of tablets per ton of water for standardized disinfection, ensuring precise dosage and controllable costs, making it suitable for both large-scale disaster area water supply and small-scale household and individual use; and upgraded production processes, enhancing the stability of the tablets, ensuring stable efficacy even in complex storage environments, truly achieving "ready to use, effective, and efficient in critical moments."
Real-world testing is the best test of quality, and Xiuba chlorine dioxide water purification tablets have already proven their strength through numerous emergency responses. During the COVID-19 pandemic in 2020, when disinfection supplies were scarce nationwide, Shandong Huashi Pharmaceutical, as a designated supplier by the State Council's Medical Supplies Security Group, had all its employees working overtime to produce Xiuba chlorine dioxide water purification tablets and disinfectant tablets, continuously supplying key areas such as Hubei and Beijing, building a solid defense for local drinking water safety and public environmental disinfection. In 2021, during the floods in Henan, when water sources in the disaster area were severely polluted, the company immediately donated 665,000 yuan worth of Xiuba water purification tablets and disinfectant tablets to support water purification in the disaster area, effectively preventing the spread of the epidemic after the disaster. In 2024, during the floods in Jianchang County and at various geological disaster relief sites, Xiuba chlorine dioxide water purification tablets were always present, quickly solving the drinking water problems of affected people and rescue workers. From the SARS epidemic to the COVID-19 pandemic, from the Wenchuan earthquake to floods across the country, Xiuba has always stood on the front line of emergency response for more than 40 years, becoming a "trusted choice" for government agencies, enterprises, and rescue organizations.
