CPC F24F 8/22 (2021.01) [A61L 9/205 (2013.01); A61L 2209/111 (2013.01); A61L 2209/16 (2013.01)] | 13 Claims |
1. An apparatus for cleaning a fluid, comprising a through-channel for the fluid, a radiation source device, and a photocatalysis device, the radiation source device emitting electromagnetic radiation, it being possible for the photocatalysis device to be exposed to at least some of the electromagnetic radiation in order to generate a photocatalytic reaction,
wherein a sensor device is provided to detect at least one change in radiation parameters of the electromagnetic radiation, a control device being connected to the sensor device via signals, it being possible to modify at least one control parameter of the radiation source device by means of the control device in case of a deviation of the radiation parameter from a setpoint/threshold value or setpoint/threshold range,
wherein the radiation source device comprises a total number (Ntot) of radiation sources and the at least one control parameter is an operating number (NO) of radiation sources, and
wherein, in a first operating state, the operating number (NO) of radiation sources is smaller than the total number (Ntot) of radiation sources and the radiation source device is emitting electromagnetic radiation with an optimal radiation parameter, it being possible for the operating number (NO) of radiation sources to be increased by means of the control device in case of a deviation of the radiation parameter from a setpoint value range in a form of falling below a threshold value such that the optimal radiation parameter continues being emitted by the radiation source device with an unchanged operating current (IO).
