Unlike chemical approaches to water disinfection, UV light provides rapid, effective inactivation of microorganisms through a physical process. When bacteria, viruses and protozoa are exposed to the germicidal wavelengths of UV light, they are rendered incapable of reproducing and infecting.icroorganisms are inactivated by UV light as a result of damage to nucleic acids. The high energy associated with short wavelength UV energy, primarily at 254 nm, is absorbed by cellular RNA and DNA.
Applications ranging from curing to disinfection and sterilization will benefit from new UV LEDs in the 265â300-nm band. Nikkiso America has announced the general availability of 50-mW deep-ultraviolet (UV) LEDs that the company said have operating lifetimes in excess of 10,000 hours. The evolution of UV-LED technology at shorter wavelengths holds great potential for applications ranging from industrial curing to water sterilization.
