摘要： Method for determining the UV transmittance of water in a UV disinfection plant, through which water flows, wherein the UV disinfection plant has a plurality of radiator arrangements, each with a UV radiation source, a sleeve tube which surrounds the UV radiation source and which has an end face at an open end, and with a UV-C sensor which detects the UV radiation emerging from the sleeve tube without the influence of the water, and with at least one further UV sensor which is arranged at a distance from the sleeve tubes of the radiator arrangements, wherein the method includes the following steps: measuring the UV radiant power emerging from the sleeve tube; measuring an amount of the transmitted radiant power by the further UV sensor; and determining the transmittance of the water by an amount of the emerged radiant power and of the transmitted radiant power.

摘要： An apparatus for the treatment of water includes an elongated housing having a first end and a second end. The first end has a water inlet and the second end has a water outlet. An elongated ultraviolet radiation source with a sleeve is concentrically located within the elongated housing. The elongated ultraviolet radiation source has, at its first end, electrical connections, which extend through the second end of the housing and have a second free end held in a support element. The support element includes a supporting structure containing a ring element and from thereon radially inwardly running arms. The arms are designed in such a way that during assembly the arms are resiliently deformed and wherein, if assembled, the arms are pressed against the sleeve, so that the free end of the ultraviolet radiation source is held by the arms in a resilient manner.

摘要： A UV radiator unit includes an elongated gas discharge lamp with an essentially cylindrical UV transparent lamp body with sealed ends, which encloses a gas volume. The lamp body defines a longitudinal axis and has an outer diameter. A UV transparent sleeve tube with an inner diameter, which surrounds the lamp body and wherein the inner diameter is larger than the outer diameter of the lamp body. At least one damping ring is interposed between the lamp body and the sleeve tube. The damping ring includes a first side element, a second side element and at least one connecting portion. An axial distance is provided between the first side element and the second side element. The at least one connecting portion physically connects the first side element and the second side element.
