Ultraviolet light is a type of light wave that is invisible to the naked eye and exists on the outer side of the ultraviolet end of the spectrum, hence it is called ultraviolet light. According to different wavelength ranges, it is divided into three bands: A, B, and C.

Sterilization lamp is a type of mercury lamp, in which excited mercury atoms inside the lamp tube can emit characteristic spectral lines of different wavelengths during transitions. The energy contained in the 254nm spectral line can effectively destroy the DNA molecular structure of microorganisms such as bacteria and viruses, achieving the purpose of sterilization; The 185nm spectral line can generate ozone in the air, and ozone can also have bactericidal and deodorizing effects; The 185nm spectral line can also decompose organic molecules in water, generate hydroxyl radicals, and ultimately oxidize organic molecules in water to carbon dioxide, achieving the goal of removing TOC.

The ultraviolet sterilizer is made of 304 or 316L stainless steel as the main material, with high-purity quartz tube as the sleeve, and is equipped with high-performance quartz ultraviolet low-pressure disinfection lamp tube. It has the advantages of strong sterilization power, long service life, stable and reliable operation, and its sterilization rate is ≥ 99%. The service life of imported lamp tube is ≥ 9000 hours.

Characteristics of UV sterilization:

(1) UV sterilization is fast, efficient, and effective.

(2) Ultraviolet irradiation does not alter the physical and chemical properties of water, and does not cause pollution to pure water due to the introduction of additives.

(3) Suitable for various water flow rates, easy to operate, convenient to use, just need to regularly clean the quartz glass sleeve and replace the lamp tube.

(4) Small size, lightweight, and low power consumption.

(5) UV sterilization does not have a continuous disinfection effect and is susceptible to secondary pollution.
