The way UV disinfection works is based on ultraviolet light in the wavelength range from 180 to 280 nanometres (nm). This has the effect of reducing germs. During UV disinfection, the cell structure of bacteria, viruses, algae and other micro-organisms is permanently damaged by UVC radiation. The genetic material (DNA) is changed in such a way that the reproduction of the micro-organisms is damaged and they thus die. The UVC lamps used in our UVC systems radiate in the optimum wavelength range of 254 nm. UV disinfection takes place in fractions of a second. There is no need for long dwell times for this process. UVC radiation has proven to be an environmentally and health-friendly alternative to water disinfection using chemicals. We, the company UST Umwelt-Systemtechnik GmbH Gera, have been using this technology optimally in our UVC systems for 15 years now.
