Degermination methods UV-radiance

Elimination of bacteria with UV-rays:
The rate of solar radiation in the wavelength range beneath the visible light is referred to as ultraviolet-radiation. (Unit: Nanometer = nm = 1/1.000.000.000 m)
It has been known for some time that sunlight prevents the spread of infections. Later on it was recognized that this effect came from the invisible part of solar radiation beneath 320 nm.
Today we know that short-wave UV-C radiance, especially in the region of 254 nm, has a strong germicidal effect.
Radiation under 200 nm is built out of atmospheric oxygen which, besides its degerminating effect, neutralizes (oxidates) organic compounds.
The effects of ultraviolet rays:
When microorganisms are exposed to UV-radiance the cell nucleus is mutated so that a segmentation is not possible which then prevents reproduction. UV-radiance causes damage to the cells through alteration of important enzymes and the DNA. The microorganism dies within a short period of time.
Advantages in UV-Degermination in comparison with other procedures:
  • No use of chemicals
  • No environmental pollution
  • Water keeps its natural flavor and smell
  • Effective within seconds at germination rates from up to 99,9%
  • Health-harming byproducts are nor created
  • Highest operational safety through UV-monitoring
  • Corrosive materials are not created
  • Water meets the requirements of the German Drinking Water Ordinance (TVO)
  • No risk of overdosage
  • Low investment- and operating-costs
  • Minor maintenance effort
Result:
UV-Degermination is the most efficient, cheapest and harmless of all current degermination-methods.
Beyond dispute, the biggest advantage of this procedure is that dangerous substances will not be added to the water. Therefore the waters’ flavor nor chemical consistence will be altered.
With thousands of installed equipments worldwide, UV-technology has proven that UV-radiance is highly effective against pathogenic agents, viruses and bacteria. The use of nonpolluting UV-light instead of potentially harmful chemicals will lead to a microbiological deactivation-rate of 99,99% and higher. Water is therefore safe, hygienic and low priced.
UV-equipments are technically easy to handle and effective. They are low maintenance and reliable. Handling with dangerous gases does not apply. There is no harm for the operator or the environment.
