Disinfecting e.g. drinking water by UV lamps, comprises subjecting water to be disinfected to UV radiation emitted from UV lamps, where each lamp functions under its own power that is different from other lamps

摘要

The method comprises subjecting water to be disinfected to an UV radiation emitted from UV lamps (1.1-1.6). Each lamp functions under its own power that is different from the other lamps, and the power is given so that the lamp emits the UV radiation whose intensity corresponds to a fixed set point. The lamps comprise loops for power regulation combined with UV sensors (4.1-4.6) for adjusting a power supply of the lamps to obtain a value of set desired intensity. The lamps are fed through ballasts whose load characteristics are modified by output signals of the loops in a direction.

The lamps comprise loops for power regulation combined with UV sensors (4.1-4.6) for adjusting a power supply of the lamps to obtain a value of set desired intensity. The lamps are fed through ballasts whose load characteristics are modified by output signals of the regulation loops in a direction that varies a power of the power supply of the lamps so that the lamps emit the UV radiations whose intensity corresponds to the set point. An independent claim is included for a device for disinfecting clear water such as drinking water by UV lamps.
