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.
Ultraviolet (UV) radiation is the part of sunlight which causes sunburn, skin damage and skin cancer. Ultraviolet radiation can be broken down into three bands: UVA, UVB, and UVC. The amount of UV rays reaching the Earthâs surface varies throughout the day. The danger period is between 10am and 3pm. These are the hours when skin damage occurs the fastest. On a cloud-free day, we can feel maximum ultraviolet rays. However, ultraviolet levels are not related to the air temperature. There can be high levels of ultraviolet rays on cool days and UV rays still reach the Earthâs surface when there is cloud cover.
