Demitec® Ultra Violet disinfection

UV light kills bacteria and viruses without adding anything to the drinking water, making it a very clean disinfection method. The Demitec® UV systems are specially designed for maritime applications, based on almost three decades of experience. The UV units can be mounted horizontally and vertically and are available for all capacities.

The energy (photons) of UV light must be absorbed by the target molecules to result in a change of the molecules. For example, in microorganisms, the genetic molecule DNA is ‘damaged’ after exposure to UV light. As long as the damages (such as thymine-dimers) remain present in the DNA, a microorganism cannot reproduce and is ‘killed’. Chemical bonds of other harmful (in)organic molecules are broken down after exposure to UV light, leading to the photodissociation of the molecule into harmless reaction products.
