Why is UVC used in air ducts?
UVC radiation is commonly used inside air ducts to disinfect the air. This is the safest way to employ UVC radiation because direct UVC exposure to human skin or eyes may cause injuries, and installation of UVC within an air duct is less likely to cause exposure to skin and eyes.
Why are UVC lamps used?
UVC radiation has effectively been used for decades to reduce the spread of bacteria, such as tuberculosis. For this reason, UVC lamps are often called "germicidal" lamps. UVC radiation has been shown to destroy the outer protein coating of the SARS-Coronavirus, which is a different virus from the current SARS-CoV-2 virus.
What type of lamp produces UVC?
Low-pressure mercury lamp: Historically, the most common type of lamp used to produce UVC radiation was the low-pressure mercury lamp, which has its main (>90%) emission at 254 nm. Other wavelengths are also produced by this type of lamp. There are other lamps available that emit a broad range of UV wavelengths, ...
What is UVC lamp?
A: UVC lamps are electronic products. The FDA regulates electronic products that emit radiation (both non-medical and medical products) through the Electronic Product Radiation Control Provisions, which were originally enacted as the Radiation Control for Health and Safety Act.
What are the wavelengths of UVC?
Not all UVC lamps are the same. Lamps may emit very specific UVC wavelengths (like 254 nm or 222 nm), or they may emit a broad range of UV wavelengths. Some lamps also emit visible and infrared radiation. The wavelengths emitted by the lamp may affect the lamp’s effectiveness at inactivating a virus and may impact the health and safety risks associated with the lamp. Some lamps emit multiple types of wavelengths. Testing of the lamp can determine whether, and how much, other wavelengths the lamp puts out.
What are the regulations for radiation safety?
The radiological health regulations include reporting of Accidental Radiation Occurrences, notification to the FDA and customers of radiation safety defects, and designation of a U.S. agent for imported lamps.
Is mercury toxic to UVC lamps?
Because mercury is toxic even in small amounts, extreme caution is needed in cleaning a lamp that has broken and in disposing of the lamp. Effectiveness: The effectiveness of UVC lamps in inactivating the SARS-CoV-2 virus is unknown because there is limited published data about the wavelength, dose, and duration of UVC radiation required ...
Why is filtration required in Florida?
Florida's high-level disinfection criteria were designed to ensure that the reclaimed water would be essentially virus-free.
Is UV irradiation a disinfectant?
Many utilities are beginning to evaluate and implement alternative disinfection methods, with UV irradiation among the most popular. UV has long been recognized as an effective disinfectant. However, unlike chlorine, UV does not pose disinfection byproducts, toxicity or hazardous materials concerns.
What is UV water treatment?
The use of ultraviolet water treatment systems is common in residential, commercial and industrial applications, as well as in sewage treatment plants. UV is also an effective tool in pond algae control. UV can be used in: homes, cottages, hotels, motels, buildings, factories, rinse processes, bottling plants, food processing, cooling towers, breweries, hospitals, fisheries, farms, wineries, and the list goes on.
When should UV water treatment units be installed?
Ultraviolet water treatment units should be installed after any water pre-treatment process, just before the cold and hot branch lines. If in doubt about the size of an UV unit that is needed, always use a larger unit rather than a smaller unit. Normally, an 8gpm UV unit will be installed as close as possible to the dispensing point. All the pipes should be treated with chemical shock treatment and flushed thoroughly before an UV unit is commissioned and prior to its use.
What are the advantages of UV disinfection?
UV has many advantages over other disinfection processes: 1 UV is effective and quick. No need for holding tanks and reaction times. No need for storing chemicals. 2 UV does not alter the taste of water, which makes it ideal for use in bottling plants and food processing applications. 3 UV is safe. NO need to add or handle hazardous chemicals or risk polluting the environment. 4 UV is compatible with all other water treatment processes. No need for de-chlorination if using RO systems. In fact, UV enhances the use of other water treatment by keeping them free from germs. 5 UV is economical. Almost always, the cost of UV disinfection units is much less than the cost of chemical treatment systems. The cost of service and maintenance of UV units is very low. The electrical running cost of an UV unit in a house is about that of a regular light bulb. 6 UV is more effective against viruses than chlorine. 7 Easy installation. UV units are very easy to install and require very little space.
