Some people may doubt and ask why ultraviolet light could killl the baceteria and virus. Is it really effective? Here comes the answer.
The cell has its own reaction rule that it absorb most of the light of 250~270nm wavelength, and the absorbed ultraviolet light will have photochemical reaction to cell’s DNA. The ultraviolet energy is absorbed by the basic group which returnly result in the genetic material variation and kills the bacteria or or stop the cells reproduction.
And the low preasure germicidal uv light bulbs produce most ultraviolet radiation at 254nm, which is closed to the preferred 250~270nm and recognized as the most effective for sterilization and disinfection.
And under 185nm uv ozone lamp, the UV light could decompose the oxegeon from the air, and produce the reactive oxygeon for photooxygenation happening. Then the reactive oxygeon will joint with the oxygen and comes out the ozone, which could be used for TOC degradation, odor removal, also decolorize.
Speaking for sterilization efficiency, the sterilization rate could reach up to 90% for suitable UV dose.
