The present invention relates to a device for sterilizing a fluid, including a container provided for receiving the fluid, at least one UV light source for the sterilization of the fluid and at least one measuring device for determining absorption properties and/or cloudiness of the fluid.
It is known in the art to sterilize microbiologically contaminated media, such as for example drinking water or purified waste water, by irradiation with ultraviolet light (UV light). A device of this type has become known from AT 411 250 B in the name of the Applicant, in which a UV reference sensor and an additional UV measuring sensor are provided for measuring the light passing through a reference medium or through the fluid, respectively. The evaluation of the light signals measured by the UV measuring sensor and the UV reference sensor delivers a measuring signal which is characteristic of the intensity and if appropriate of the spectral composition of the measured UV light.
