UV disinfection of drinking water How it works

How does drinking water disinfection with ultraviolet light work?

UV light is a natural component of sunlight. The wavelength of 254 nm has a particularly high energy and therefore the unique ability to kill microorganisms (bacteria, viruses, parasites, etc.) in water and air. Radiation with UV light stops the proliferation of these organisms, which can cause infections and diseases.

UV light is "simply" light energy that breaks down the DNA of dangerous microorganisms. This is the difference to chemical disinfection methods that rely on oxidation to destroy the basis of life of the microorganisms. By breaking down the DNA of microorganisms, all important life functions are destroyed and the microorganism dies. Since no chemicals are used in UV disinfection, no dangerous residues or byproducts can get into your drinking water.
