Abstract
The device for disinfecting water comprises a gas discharge lamp including a discharge vessel with walls composed of a dielectric material, which walls are provided on their outer surfaces with at least a first and a second electrode, and which discharge vessel contains a gas filling containing xenon, the inner surface of the walls being at least partly covered with a coating containing a phosphor emitting in the UV-C range. Such a device for disinfecting water can always be made 100% operation within milliseconds, and the UV-radiation of the device has a spectral composition which lies exclusively in the range relevant for disinfecting, i.e. between 230 and 300 nm.
