The Science Behind UV Disinfection

Artificially produced ultraviolet C light (UV-C) is a low cost and highly effective solution for disinfecting facilities. It has been proven to kill microorganisms including bacteria, protozoans, and fungi.  And, unlike the more commonly used UV-A and UV-B, it also deactivates viruses–including coronaviruses such as SARS CoV-1.[1]  It is a healthy and environmentally friendly alternative to spraying (or fogging) premises with toxins or other harsh chemicals.

UV light has been used for disinfecting surfaces since 1877, for water since 1910, and for air since 1935.[2]  Over the last 40 years, UV-A and UV-B have been commonly used in the US in water treatment facilities, food and beverage preparation, laboratory and healthcare facilities, in ductwork, and even in household tropical fish tanks. In Europe, UV-C has been used for more general disinfecting purposes over the last few decades.[3]

 

 

 

Due to the Covid-19 pandemic, caused by the novel coronavirus SARS-CoV-2, UV-C is a timely solution for more general disinfection purposes in the US.  Studies show, that UV-C is effective against known coronaviruses such as SARS. [4]

UV kills microbes and deactivates viruses by disrupting their DNA and RNA, leaving them unable to infect or replicate.  Bacteria and viruses vary somewhat in UV susceptibility, with fungal spores and mycobacteria being relatively harder to kill than more rapidly replicating microbes. But even fungi are effectively killed with high-dose UV-C.[5]

UV-C disinfects the entire area treated, including all surfaces and the interior air.  It is complimentary to the daily cleaning and disinfecting regime required for high-touch areas.  UV leaves no odor or residue.  It gets into hard to reach areas, yet it requires no moving of furniture, electronic devices, machinery, or desktop papers.

Understanding UVC

The Electromagnetic Spectrum

 UV light is to the left of visible light on the electromagnetic spectrum, with shorter wavelengths, measured in nanometers (nm).  UV-C is at the shorter end of the UV spectrum.  Its waves have higher energy and are more penetrating than the longer wave UV-A and UV-B.  The higher energy and higher penetration rate is a two edged sword; it makes UV-C more lethal to microbes, but it will damage human skin and eyes if they are subjected to significant exposure.  UV-C must only be administered by professionals trained in both efficacy and safety measures.

The UV and Visible Light Spectrum

Within the UV-C spectrum, different wavelengths have different properties.  It has been determined that UV-C at 254 nm is in the range most effective for killing microbes.  This technology kills 99.999% of bacteria and viruses in direct contact with UV-C light.[1]

In a workplace or residential application with multitude of items like furniture, shelving, machinery etc. in the space we use Vacuum-Ultraviolet light (VUV), also known as UV-O.  UV-O, at 185 nm also has direct germicidal impact on microbes that it hits directly.  But UV-O has a special property: the ability to generate ozone. Ozone is a powerful disinfectant with the ability to kill microbes on its own. Ozone dissolves lipids in the cell wall to kill bacteria and most other microorganisms. In fungi, ozone inhibits cell growth which leads to death. Ozone deactivates viruses by damaging the outer sheath, (viral capsid) preventing them from replicating or binding to the cell walls of their target.[2] 

High energy UV-O light excites oxygen atoms (02) into ozone atoms (03).  The ozone then spreads out from the lighted areas to disinfect the air and surfaces not directly hit by the UV-C light.  Research shows that UV-O light provides a thorough disinfection, even for large aerosols contaminated with pathogens where direct UV illumination cannot penetrate.[3]

When the UV-O lamp is turned off, in the absence of the high energy waves, the ozone atoms revert to oxygen over a period of time.  In a standard application the operator allows approximately 1.4 times the duration of the disinfecting time frame for the ozone to revert to oxygen. Rather than leaving a chemical odor, the process of ozone reverting to oxygen leaves a fresh outdoor air smell.

So-called “Far” UV-C, at 222 nm, is also a useful type of UV-C for disinfection, and it has the additional benefit of not penetrating human skin or eyes enough to be harmful.  Because it is less penetrating, however, it is only useful for disinfection of airborne microbes.  It cannot kill the layers of microbes that can form on a surface.  So Far UV-C is primarily used for upper room systems and ventilation system disinfection.

There are practical uses for machines that disinfect with UV-C without producing ozone.  Other applications clearly require the addition of UV-O to produce ozone.  And, as already mentioned, air disinfection in the presence of humans call for Far UV-C.  There are different types of mercury vapor, induction, or LED lamps that produce germicidal UV-C for each usage.  Different types of lamps producing different types of UV-C can be combined in one fixture to get optimal results.  Fixtures producing approximately 90% 254 nm UV-C plus 10% 185 nm UV-O have been found to be most effective for general disinfection.[4]
