The water tank ozone sterilizer is a high-efficiency disinfection device specifically designed for water tanks, reservoirs, and related water storage systems. By releasing high-concentration ozone gas, it achieves sterilization, algae removal, odor elimination, and decomposition of organic contaminants. Utilizing the strong oxidative properties of ozone, it rapidly destroys the cell structure of bacteria, viruses, and fungi, ensuring water quality meets drinking or industrial standards. The product features corrosion-resistant materials and a sealed design, capable of long-term stable operation in high-humidity and high-temperature environments. It is equipped with an intelligent control system that supports automatic timed operation, ozone concentration adjustment, and fault alarm functions, reducing maintenance costs. Suitable for drinking water reservoirs, firefighting water tanks, industrial circulation water systems, and large-scale water storage facilities. Easy to install, requiring no additional chemicals, it is environmentally friendly with zero secondary pollution.
