Web9 Jun 2016 · Scientists have known for some time that UV light has the ability to kill bacteria, even pathogens like MRSA, referred to as “superbugs.”. However, the UV lamps required for this type of ... The effectiveness of germicidal UV depends on the duration a microorganism is exposed to UV, the intensity and wavelength of the UV radiation, the presence of particles that can protect the microorganisms from UV, and a microorganism's ability to withstand UV during its exposure. In many systems, redundancy in exposing microorganisms to UV is achieved by circulating the air or water repeatedly. This ensures multiple passes so that the UV is effective against the highest …
