The disinfection principle of ultraviolet light?

There are many ways to demonstrate, sample or measure many things that happen. One is to use a contact plate containing malt agar. Before installing the UV-C, please lightly touch the surface with the board. Then it was incubated for approximately 96 hours. After installing UV-C, this step will be performed again at the same location. People often see a reduction in growth of organisms by more than 98%? Different bacterial growth media can be used to similarly sample the water pan and its water. Some other methods are:

o A significant reduction in mold can be seen in a short period of time.

o It has been shown that in less than 30 days, the coil pressure drop has dropped by more than 10% (depending on surface cleanliness and water activity). Of course, system airflow and capacity usually increase accordingly.

o The drain pan and the water in the drain pan have become cleaner.

o All field wire surfaces, such as insulation materials, etc., will start to look cleaner.

o Most of the related odors produced by irradiated pollutants disappeared.

o Many indoor air quality complaints have been recorded as reductions.

What is UV lamp inactivation?

For molds and bacteria, UVC energy doses may not immediately cause cell death, but microorganisms may be "inactivated." This means that although some biological activity may still exist, cell replication is impossible. Microorganisms are no longer viable. In short, the target microorganism cannot reproduce, so it is harmless! Moreover, over time, small doses of UV-C can accelerate cell death. Because virus particles are not a form of life, we only rely on inactivation to get rid of our imminent harm.
