Method And Reactor Device For Disinfecting Water By Means Of UV Lighting

A reactor device for disinfecting water such as drinking water, waste water, service water, or process water by means of UV lighting, with:

• a reactor chamber for receiving water which is to be disinfected;
• a UV lighting system with an arrangement of UV light emitting diodes for the UV illuminating of the water which is to be disinfected in the reactor chamber;
• a driver system, which is associated with the arrangement of UV light emitting diodes;
• a monitoring system;
• and
• a control system, which is connected to the monitoring system and to the driver system;
• wherein the reactor device is configured for the following:
• delivering the water which is to be disinfected via an inlet in the reactor chamber, illuminating the water which is to be disinfected with UV light in the reactor chamber by means of the UV lighting system, and discharging of disinfected water from the reactor chamber via an outlet;
• providing the UV light by means of the arrangement of UV light emitting diodes;
• operating the UV light emitting diodes by means of the associated driver system;
• controlling an operation of the driver system by means of the control system;
• monitoring of at least one electrical operating parameter for the arrangement of UV light emitting diodes during the disinfecting of the water by means of the UV light with the aid of the monitoring system;
• comparing a current measurement value for the at least one electrical operating parameter, which is detected by means of the monitoring system, with a comparative value for the at least one electrical operating parameter;
• generating control signals as a function of the result of the comparison of current measurement value and comparative value for the at least one electrical operating parameter;
• and
• controlling the operation of the reactor device in accordance with the control signals,
• wherein a UV lighting system is provided, in which the arrangement of UV light emitting diodes comprises a plurality of partial arrangements of UV light emitting diodes, which form a respective UV lamp and which in operation of the UV lighting system can be operated separately from one another by means of the driver system and can be controlled separately from one another separately from one another by means of the control system, such that the at least one electrical operating parameter can be detected respectively separately for the plurality of UV lamps, so that an individual monitoring of the respective partial arrangement of UV light emitting diodes is enabled, and the control system is configured to generate individual control signals separately for the respective partial arrangement of UV light emitting diodes.
