An environmentally friendly and easy-to-handle method is irradiating water with ultra-violet light.
UV light is invisible light with a wavelength of 200 to 400 nm. For UV disinfection, the irradiation with the shortest wavelength and the highest energy, i.e., the UVC light is important. Its wavelength is 200 nm to 280 nm. Maximum efficiency is achieved at a wavelength of 254 nm, since at this point the absorption curve of nucleic acid and the irradiance of the low pressure UV lamps have a common maximum.
UV disinfection does not contaminate the water with chemical waste products; it is completely harmless and impacts neither odour nor taste of the water. Furthermore, the irradiated micro-organisms cannot develop any resistance.
Herco UV disinfection units are technically sophisticated and monitor themselves. Herco offers standard units in different sizes and develops customised solutions.
