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 Disinfection 1 Ultraviolet (UV) sanitizing units are used in many water purification systems to control bacteria and havecertain applications in animal drinking water systems. Ultraviolet Disinfection FlowrateAll UV units have a maximum flowrate capacity and some have a minimum flowrate as well. Ifthe flow is too high, water will pass through without enough UV exposure. If the flow is too low,heat may build up which can damage the UV lamp.
