  • UV light is absorbed after passing through a transmission path and the light intensity is determined. This provides information on the proper functioning of the light source as well as essential information on whether the light of the light source reaches a certain predetermined depth of penetration into the surrounding water in order to ensure adequate disinfection throughout the chamber.
  • the object of the present invention is to provide a generic disinfection device, which ensures the disinfection safety even with uncertain water flow and reduces the need for cleaning.
  • the transmission path is arranged in the inflow and connected to the light source via a light guide.
  • the original light of the light source is used.
  • the reduction in water penetration that would occur in the chamber itself is measured in the transmission path in front of the chamber.
  • the device can be shut down immediately before the contamination reaches the chamber. This therefore always remains sterile and does not have to be cleaned and disinfected every time contamination occurs. the.
  • the disinfection device according to the invention is suitable for disinfecting or disinfecting liquids of all kinds, for example for water for treatment to drinking water or sterile water eg for medical purposes or for drinks to preserve them, provided that they are sufficiently transparent for UV light.
  • a valve controlling the flow through the chamber allows a complete stop of the flow.
  • the valve is arranged in the inflow and thus can keep the chamber completely free from the inflowing impurities.
  • the valve is arranged according to claim 4 between radiating distance and chamber, so that the contamination is measured in front of the valve and certainly can not get into the chamber.
  • the features of claim 5 are provided.
  • the contaminated water is added to a drain where it flows out into the open.
  • In the transmission line can be measured until the water quality has recovered, and then switch the valve back to passage to the chamber.
  • the lines to the valve are then rinsed free again.
  • the features of claim 6 are provided.
  • the evaluation unit can throttle the valve, so that the chamber is operated with a reduced water flow rate, which ensures sufficient disinfection throughout the chamber even with the reduced penetration depth of the UV radiation.
  • the features of claim 7 are provided. In this alternative way, the contaminated water can be passed through a filter to the chamber, which eliminates the impurities.
  • the features of claim 8 are advantageously provided, according to which the switchover to a filter is controlled by an additional measuring device in the inflow, which measures not the reduction of UV radiation, but other water parameters.
  • Any suitable measuring device may be used, for example a spectrometric measuring device, e.g. operates with a broadband irradiated transmission path and e.g. Detect toxins, even if they do not absorb in UV light.
  • the filter may be suitably designed to absorb such toxins, e.g. as a coal active filter.

  • light losses both in the chamber and in the inflow can be monitored simultaneously.
  • the brightness-reducing soiling of the light source surface is detected.
  • the features of claim 10 are provided. If the chamber is irradiated by several light sources, for example, rod-shaped inside or as Spotlights can be arranged in the wall of the chamber, then advantageously the light of each light source is collected separately and fed via optical fibers of the transmission path in the inflow. This makes it possible to monitor the proper functioning of the individual light sources in addition to the impurities in the inflow.
