Overflow UV Sterilizer

Made from food-grade stainless steel (304), the UV sterilizer is non-toxic, rust-free, pressure-resistant, corrosion-resistant, and produces no metal ion contamination, fully complying with food-grade hygiene requirements.

This UV sterilizer is suitable for water supply systems in various buildings and other backup water storage tanks. It is also suitable for food and beverage processing plants and independent water supply systems with various pipe diameters and flow rates. It is also suitable for use on ships and in field systems. Professionally certified by health and epidemic prevention authorities, the UV sterilizer has a water virus and bacteria kill rate exceeding 99.99% and is easy to use and maintain.

Preparation of Chlorine Dioxide

Chlorine dioxide can be prepared by electrolysis, activation of stabilized chlorine dioxide, and chemical methods.

① Electrolysis: Similar to the production of sodium hypochlorite by electrolysis of salt water, the electrolysis method produces chlorine dioxide by electrolyzing salt water and sodium chlorate solution. However, this method has a limited lifespan for the diaphragm and electrodes, produces low concentrations of chlorine dioxide, and requires complex equipment and difficult operation and maintenance.

② Stable chlorine dioxide activation method. Chlorine dioxide is unstable and generally requires on-site production. To achieve this, high-purity chlorine dioxide is first produced and stabilized with stabilizers such as carbonates for easy storage and transportation. Upon use, it is activated with activators such as hydrochloric acid to produce chlorine dioxide. While stable chlorine dioxide is easy to use, it is relatively expensive and is only suitable for small-scale water disinfection in economically affluent areas.

③ Chemical methods: Chemical methods are currently the most commonly used methods for drinking water purification, including the chlorate and chlorite methods.
