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.
