.V sterilization is a proven method of eliminating a variety of waterborne microorganisms. Ultraviolet light is a natural component of the electromagnetic spectrum and very lethal to pathogens. It falls to the left of visible light with higher energy levels and wavelengths between 100 and 400. The most effective and often used wavelength for disinfection is at 254 nm. The light necessary for UV disinfection is generated in special UV lamps. A watertight quartz tube surrounds each lamp. The liquid to be disinfected is passed through the quartz tubing.

The gas plasma generated in the lamp emits light with a primary wave length of 253.7 nm. This intensive UV light reaches the microorganisms in the water and impacts directly on their DNA. By changing the DNA, the cell division of the microorganism is interrupted - it can no longer reproduce itself and thus loses its pathogenic effect. With INDWA UV technology it is possible to destroy more than 99.9% of all pathogens in water. This process is highly efficient and reliable without any side effects and addition of chemicals.
