Sterilization Principle and Operating Model

UV ray is an invisible light, locating at outer side of violet rays in the spectrogram. Therefore it is called as ultraviolet light, with wave length between 100nm and 400nm. UV ray can be divided into A, B, C and vacuum ultra violets as per the wave length.

Ultraviolet C is shortened to UV-C with wave length between 200nm and 280nm. UV-C with wave length of 253.7nm has the best sterilization effect, which is origin of modern UV-C.

Through the studies, UV ray mainly kills the microbes (pathogene such as germs, virus, gemma of fungus, etc) by radiation damage and function destruction of nucleic acid for the purpose of sterilization. UV rays can cause the breakage of nucleic acid’s strand, inter-strand cross-linking and formation of photochemical products, etc. thus to change the biological activity of DNA and inhibit the reproduction of microbes. Therefore, this UV damage is also fatal.

* UV radiation (UVC) can destruct the DNA of microbes irreversibly so that they can not reproduce until death finally.

The advantages of the ultraviolet disinfection

1. Ultraviolet disinfection technology is very expeditious in destroying bacteria.

UV energy can destroy bacteria and virus in just about 1-5 seconds. In order to reach the same disinfection effect, it costs about 30 minutes or more contact time by use other chemical methods (Chlorine, Ozone, Chlorine Dioxide).

2. Comprehensive range of disinfection.

Ultraviolet disinfection technology has been widely applied for efficiently destroying pathogenic microorganisms, bacteria and virus.

3. No secondary pollution.

Since no chemical is added, ultraviolet disinfection system will not cause secondary pollution for water and environment.

4. Low operational costs, simple operation and maintenance and economical prices.

5. Occupied small space

Occupied small space and easy assembly enable UV equipment to be installed at the place near water and power source. The ultraviolet equipment starts working after connecting the inlet and outlet of the Ultraviolet equipment and powering up.
