Abstract: A method for producing ozone at elevated pressure with a capacity of at least 1 kg ozone/hour by an ozone generator having a high voltage electrode and a counter electrode. The electrodes delimit a gap in which a dielectric is arranged and through which a gas containing oxygen and having a gas pressure of pgas flows. The high voltage electrode and the counter electrode with a connection for an electric power supply to generate discharges are provided in at least one discharge gap. The power supply provides a voltage in a range from 1 kV to 50 kV and wherein stroke widths di of the discharge are distributed between a minimum stroke width dmin and a maximum stroke width dmax. The gas pressure pgas of the gas containing oxygen at the outlet of the ozone generator is at least 3 bar.

Abstract: 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.

Abstract: A low pressure mercury gas discharge ultraviolet lamp with a tubular elongate body with two opposing ends, a first end and a second end, which contains a gas filling, and with at least two electric connectors at each end, which are electrically connected to at least one filament being provided at each end. A discharge length is defined between the filaments, in which at least two filaments are provided at each end of the discharge length. The filaments can be individually supplied with electric energy. The at least two filaments at the first end are of different size and different mass, and the at least two filaments at the second end are of different size and different mass.

Abstract: An ozone generator includes a high-voltage electrode and at least one counter electrode, which define an interstice in which at least one dielectric is arranged and through which a gas flows in the flow direction. The high-voltage electrode and the at least one counter electrode are provided with a connection for an electrical voltage supply to generate corona discharges which are discharged from surface discharge locations. The mean sparking distance and the mean spacing between the high-voltage electrode and the at least one counter-electrode are constant. The number of surface discharge locations decreases in the flow direction.

Abstract: A chain tensioning arrangement for a column pipe which is configured to house a submersible pump. The chain tensioning arrangement includes a radially extending cross beam, a spring arrangement connected to the cross beam, at least one spring member, and an arm that is movably connected to the cross beam. The arm includes an engagement member configured to optionally engage a chain connected to the pump. The arm is displaceable in the axial direction between a lower position and an upper position. The spring member is arranged to displace the arm in the direction from the lower position towards the upper position. Also described is a pump station including a column pipe, a submersible pump arranged in the column pipe and an axially extending chain connected to the pump and configured to move the pump in the column pipe.
