Recent studies have shown that UV shortwave radiation is capable of eliminating viruses, such as COVID-19, MERS, and SARS viruses at the hospital level, thereby improving the cleanliness of the intensive care area, general practice wards, and individual rooms.
For several years UV light has been widely used to sterilize small residential flows, as well as large flows in commercial and industrial projects. In some countries, UVC lamp(หลอด uvc, which is the term in Thai) systems are already being used to avoid infection and contribute as a practical solution in the fight against the spread of viruses.
These types of disinfection mechanisms work with UV light and have a germicidal effect. Depending on the wavelength, the impact of UV rays can be more or less effective against various microorganisms by destroying nucleic acids and DNA.
How Does It Work?
Ultraviolet sterilization is the process of destroying all microbial life through ultraviolet radiation.Ultraviolet or UV light, as it is usually referred to, is one of the proven means of treating biologically contaminated water, air, or surfaces.
Being exposed to sunlight, this type of radiation is capable of eliminating germs, bacteria and fungi in a natural disinfection process. However, for more efficient use, they can be applied in a controlled manner through a physical process, unlike of clarification and zoning, which are chemical processes.
Use OfUV Lamps
The radiation needed to disinfect can be produced using low pressure, low/high intensity, or medium pressure, high-intensity mercury vapor (most recently antimony) lamps. For this, the germicidal lamps must have corresponding protections since the impact of UV radiation on the eyes has a harmful effect on health.
As already mentioned, the significant difference of disinfecting surfaces using ultraviolet light compared to other chemical methods is that UV light provides a fast and efficient inactivation of microorganisms through a physical process. However, it should not be overlooked that, by nature, UV radiation is potentially harmful to humans. Therefore, its use has complexities in terms of cost, manual operation, among others.
