UV radiation in the wavelength range of 200 - 300 nm has very strong disinfecting effect. Within a short contact time, living microorganisms such as bacteria, viruses, yeasts, etc. are inactivated. The absorption of UV radiation disrupts the genetic information of the microorganism, which is not repaired by microorganisms. Therefore, they are unable to grow or reproduce further. For this reason, UV disinfection has found wide application in many fields. UV lamps are used in drinking water treatment and wastewater treatment to disinfect water as the final treatment step. In process water, they are also used, for example, to reduce TOC concentrations in the semiconductor industry or in the sterilization of circulation circuits for ultrapure water. Another possibility is the use in advanced oxidation processes (AOP), where ozone or hydrogen peroxide are combined with UV radiation to produce hydroxyl radicals that have very strong oxidative effects. The application of UV disinfection is limited to waters with high transmittance and low turbidity. Otherwise, it is problematic to achieve the required UV dose needed for disinfection.
