As a facility manager, any investment in equipment you make needs to have a very clear purpose. UV technology can be a sound investment for many different types of facilities because the fact is that UV disinfection is appropriate in many different scenarios.
Following are five ways that a spectrum of facilities can utilize UV disinfection effectively.
Air Disinfection
Any facility that needs to disinfect air spaces can use a UV light to do so, to some extent. There needs to be sufficient contact of the air with the UV light, making this type of disinfection more effective on still or stagnant air than on moving air. To improve the efficacy of air disinfection, many facilities choose to install UV disinfection lights at the upper level of the room, so as the air naturally circulates, it will be cleaner. Facilities can also choose to install UV lamps near coils and drain pans of cooling systems such as air conditioners and refrigeration devices, which can prevent bacteria from growing in those cool, damp conditions and eventually being released into the air.
Water Disinfection & Wastewater Treatment
Facilities can also use UV light to disinfect water and even for wastewater treatment. Because UV disinfection is a physical process and does not require adding any chemicals to the water to clean it, this can be a very safe and effective option. UV light can reduce the incidence of parasites such as cryptosporidia or giardia, which can be resistant even to chemical disinfection. One facility in New York uses UV light to treat more than 2 billion gallons of water a day for use in New York City.
While wastewater treatment must take place on a much larger scale, UV light can play a major role in this process as well, even taking the place of chlorination. While UV light is not used as a sole disinfection protocol, it has become quite common in many metropolitan areas as part of the wastewater treatment process.
Surface Disinfection
It should come as no surprise that UV light can be useful for disinfecting surfaces in healthcare facilities and other spaces. In fact, UV light can destroy active viruses and other pathogens on a surface in just a matter of seconds. In this case, UV in healthcare facilities, can be much more efficient and effective than other cleaning and disinfecting options.
Equipment Disinfection
In addition to stationary surfaces like countertops, tables, and floors, UV light is a popular disinfection solution for equipment. For example, laboratories that risk contamination may use UV to disinfect goggles, glassware, or other laboratory instruments. As with other applications, the UV light has the benefit of being effective but also dry and simple, unlike washing or bleaching, which can leave residue and moisture behind.
Food & Beverage Disinfection
The use of UV light in food and beverage disinfection combines the effectiveness of UV light on surfaces as well as liquids. UV disinfection has been shown to be effective in food manufacturing facilities when used to disinfect things like conveyor belts that are otherwise difficult to clean thoroughly. When the right products are used, these types of surfaces can be disinfected without shortening the life of the equipment.
When considering those applications for which UV light can be used as a disinfection method, it is also important to consider the type of UV light in use. Far-UV and near-UV can have different effects on bacteria and viruses. To learn more about the use of far-UVC in disinfection, be sure to download our guide below.
Our UV-FORCE® technology can destroy pathogens smaller than <.3 microns, which are more likely to penetrate a HEPA-filter, and it can clean the air up to 99.99% in less than a second.

UV disinfection system is recommended for the disinfection of wastewater after treatment, as well as for the disinfection of drinking water. The main advantages of UV disinfection are.
(1) UV disinfection system technology has a high sterilization efficiency, safe and reliable operation. UV disinfection has a high inactivation efficiency for bacteria and viruses and because no chemicals are added.
Therefore, it does not cause secondary pollution to the water body and the surrounding environment.
(2) Effective disinfection of Cryptosporidium and Giardia. The conventional chlorine disinfection process has a low inactivation effect on Cryptosporidium and Giardia and produces a large amount of disinfection by-products at a high chlorine dose, while UV disinfection has a high inactivation effect on Cryptosporidium and Giardia at a low UV dose.
(3) No toxic and harmful by-products, no increase in the TOC content of drinking water. UV disinfection does not change the characteristics of organic matter, and because no chemicals are added, no harmful by-products are produced, and there is no increase in TOC and BOD and other by-products that damage the biological stability of the water in the network.
(4) Can reduce odor and degrade trace organic matter, UV has a certain degradation ability for a variety of trace organic matter in water, and can reduce the odor and taste of water.
(5) UV disinfection system covers a small area, simple operation and maintenance, low cost. For disinfection of 50,000 tons of sewage per day with chlorine, a 130-meter-long, 3-meter-wide contact channel is required. With UV disinfection, only an area of 20 meters long and 3 meters wide is required; UV disinfection is simple to operate and maintain, and the operating cost is low, up to only 4 cents per ton of water or even lower, so its performance to price ratio has great advantages.
(6)Disinfection effect is little affected by water temperature and pH.
UV disinfection system technology also has certain disadvantages in engineering applications, mainly in the following areas.
(1) No continuous sterilization capability, disinfected water will be contaminated again if it encounters new sources of pollution, and needs to be used in conjunction with chlorine.
(2) Turbidity and suspended matter in the water have a greater impact on UV sterilization, reducing the disinfection effect.
(3) UV lamp casing is prone to scaling, which affects the transmission of UV light and sterilization effect, so regular cleaning of the casing and surface cooling measures are needed to prevent the formation of scale.
(4) Bacterial resurrection phenomenon, some bacteria inactivated by UV irradiation virus bacteria can repair their own damaged tissues through the assistance of light to achieve the purpose of resurrection, and some other bacteria may exist in the dark resurrection phenomenon (without light).
