Abstract: An ozone generator with a high voltage electrode and at least one counter electrode which limit a gap in which at least one dielectric and an electrically non-conductive structure are arranged and through which a stream of gas flows in a direction of flow. The high voltage electrode and the at least one counter electrode are provided with a connection for an electrical voltage supply in order to generate silent discharges. The electrically non-conductive structure contains pores with a nominal pore size (x) of 100 μm

Abstract: A de-blocking device for a hydraulic pump includes a can having a longitudinal axis and a conduit extending longitudinally along the longitudinal axis and having a first terminal aperture. The device further includes a bearing fixedly positioned in the conduit spaced from the first terminal aperture, and a plunger axially movably positioned in the conduit between the bearing and the first terminal aperture. A biasing element is positioned between the bearing and the plunger wherein the movement of the plunger toward the bearing compresses the biasing element.

Abstract: Method for controlling a water treatment installation having a supply, an ozonisation stage, a transfer stage, a biological filter and a discharge having the following steps: measuring a first parameter set in the supply, wherein, a measurement for a first concentration of micro-contaminations and/or a nitrite concentration is determined; controlling the ozonisation stage in such a manner that an ozone supply is carried out in a preselected ratio to the measured first parameter set; measuring a second parameter set in the transfer stage, wherein, a measurement for a second concentration of micro-contaminations is determined; controlling the ozonisation; measuring a third parameter set in the discharge, wherein, with reference to the third parameter set, a measurement of a third concentration of micro-contaminations is determined; if the measurement for the concentration of micro-contaminations exceeds a predetermined maximum value in the discharge, increasing the ozone supply.

Abstract: An emitter arrangement includes a UV irradiation source, a cladding tube surrounding the UV irradiation source, and a UV-C sensor. The cladding tube has an end face on an open end. The UV-C sensor has a sensitive area, wherein the UV-C sensor is in optical connection with the end face of the cladding tube, so that the sensitive area of the UV-C sensor can detect the UV irradiation emerging from the end face of the cladding tube during the operation of the UV irradiation source.

Abstract: An aerator assembly for diffusing a gas in a liquid, including a gas supply conduit and at least one aerator, wherein the gas supply conduit and the aerator are releasably joined to each other by an attachment. The attachment includes a flexible body and a compressor, wherein the attachment is arranged to be reversibly set in an inactive mode, in which the gas supply conduit and the at least one aerator are in mutually released mode, as well as in an active mode in which the flexible body is compressed in its axial longitudinal direction by the compressor and clamps the at least one aerator and the gas supply conduit against each other.
