Q. How does a UV chamber work?

Answer

The ultraviolet (UV) light used in UV systems may penetrate bacteria and other microbes and modify their DNA at high enough levels. Most microorganisms are therefore made completely harmless and are unable to propagate in drinking water. In order to determine which UV light is most suited for certain tasks precise and targeted 'dosing' is employed. Consider how long certain liquids air or surfaces must be exposed to UV light until they are no longer contaminated. Ultraviolet light comprises only a small portion of the electromagnetic spectrum and even there it disperses into wavelengths shorter than those of visible light.
