Patent ID: 8212682

Claim:
A disinfection system for liquids, the disinfection system comprising: an irradiation chamber for accommodating a liquid to be disinfected; a an Ultraviolet (UV)-radiator with a cladding that is transparent to UV-light; a first Ultraviolet (UV)-sensor; and a second Ultraviolet (UV)-sensor; wherein the UV-radiator is arranged in the irradiation chamber such that the UV-radiation emitted by the UV-radiator penetrates the liquid to be disinfected; wherein the first UV-sensor is arranged in the irradiation chamber such that a first attenuation characteristic with respect to the UV-light emitted by the UV-radiator is measurable with the first UV-sensor, wherein the first attenuation characteristic includes a first aging characteristic and a first liquid attenuation characteristic; wherein the second UV-sensor is arranged in the irradiation chamber such that a second attenuation characteristic with respect to the UV-light emitted by the UV-radiator is measurable with the second UV-sensor, wherein the second attenuation characteristic includes a second aging characteristic and a second liquid attenuation characteristic; and wherein the first attenuation characteristic differs from the second attenuation characteristic.
