Demitec® Ultra Violet disinfection

Water disinfection by validated CFD optimized Demitec systems

Sources for naturally clean water are becoming increasingly rare, making it one of the world’s most valuable resources. Without proper disinfection, water is likely to contain dangerous pathogens, including Cryptosporidium and Giardia.

Disinfection using ultraviolet (UV) light is a proven, chemical-free, environmentally friendly, and sustainable method for killing pathogens and water-infecting microorganisms. Hatenboer-Water specializes in providing the optimal solution for the toughest water disinfection challenges.

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.

Demitec® UV water treatment systems target:

  • Microorganisms (bacteria, viruses, molds, yeasts, protozoa, spores, algae)
  • Disinfectants (chlorine, ozone)
  • Oxidants (hydrogen peroxide)
  • Disinfection by-products (chloramines, trichloramine)
  • (In)organic matter (NDMA, TOC)

For continuous operation of your UV system, it is advised to keep recommended spare parts such as lamps, quartz sleeves, and O-Rings on site. Replacement is required based on operational hours (e.g., lamp life is approximately 8000 hours).

Demitec® GammaLine (GS) UV Series

The GammaLine UV series is a low-cost, high-quality, and single-lamp UV system. The ‘L-shape’ chamber design makes installation very easy. The design is kept as simple as possible, so no tools are required to remove the lamp or quartz sleeve.
