Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.V light is electromagnetic radiation with wavelengths shorter than visible light. UV can be separated into various ranges, with short-wavelength UV (UVC) considered germicidal UV. At certain wavelengths, UV is mutagenic to bacteria, viruses and other microorganisms.
How does UV disinfect water. UV light is a naturally occurring component of solar radiation. It falls in the region between visible light and X-Rays in the electromagnetic spectrum.Generally, UV light is considered as falling between the wavelengths 100nm â 400nm, however UV can be categorized even further into separate regions.V light damages the DNA in bacteria, viruses, moulds and some protozoa, leaving them unable to perform cellular functions and multiply. UV is particularly highly effective against Cryptosporidium and Giardia â organisms resistant to chlorine that are a major risk to human health.
