Abstract: Propeller pump for pumping liquid, including: an axially extending tubular pump housing having an inner surface, an axially extending pump core having an envelope surface, at least one axial portion of the pump core enclosed in the pump housing. The pump core includes a propeller having a hub and at least one blade, and at least one guide vane that includes an upstream leading edge and a downstream trailing edge, and that in the circumferential direction includes a pressure side and a suction side. The guide vane extends between the inner surface of the pump housing and the envelope surface of the pump core. At the leading edge of the guide vane a connection angle between the suction side of the guide vane and the envelope surface of the pump core is larger than 90 degrees.

Abstract: A feed pump to increase the pressure in a line includes a pumping chamber for a pumping medium. At least one temperature sensor, which is arranged in the feed pump, is allocated to the pumping chamber and is in thermal contact with the pumping chamber for determining a temperature of the pumping medium in the pumping chamber. A temperature control device is allocated to the at least one temperature sensor and by which defined temperature conditions can be created in an area surrounding the at least one temperature sensor. An evaluation device to which the at least one temperature sensor is coupled for signal purposes uses the data from the at least one temperature sensor to determine whether pumping medium is flowing through the pumping chamber or not.

Abstract: A method and an installation for treating a main wastewater stream flowing in a closed conduit with a flow direction. The method includes the steps of: introducing a liquid into at least one pre-treatment stream; generating a gas stream containing ozone gas; introducing the gas stream into the at least one pre-treatment stream, each with a gas injector, resulting in at least one mixed-phase stream comprising ozone laden gas and liquid; passing the at least one mixed-phase stream through at least one static mixer, resulting in a predefined gas bubble size; and injecting the at least one mixed-phase stream in the main wastewater stream perpendicular to the flow direction.

Abstract: A treatment plant and method for controlling a treatment plant suitable for treatment of wastewater. The treatment plant includes a circulation channel housing liquid, a submersible flow generating machine arranged in the circulation channel and generating a liquid flow along the circulation channel, and a control unit that is operatively connected to the flow generating machine. The flow generating machine is driven in operation by the control unit. The method includes the steps of: driving the flow generating machine at a nominal speed, decreasing the rotational speed of the flow generating machine from the set nominal speed, detecting the rotational speed at which the torque of the flow generating machine is equal to a predetermined threshold, and determining the flow velocity of the liquid at the flow generating machine based on a predetermined relationship between the rotational speed of the flow generating machine and the flow velocity of the liquid.

Abstract: 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.

Abstract: A method for controlling a pump arrangement upon clogging. The arrangement includes a pump and a control unit. The pump includes a motor, and the control unit drives the motor. The motor during operation is associated with an operational parameter from which the motor torque may be derived. The operational parameter has a normal value PN during normal operation of the motor in a first direction. The method includes the steps of driving the motor in a first direction by the control unit, stopping the motor if a real value P of the operational parameter exceeds a predetermined clogging limit PI, driving the motor in an opposite second direction a predetermined flushing time TR by the control unit, and stopping the motor if the absolute value of the real value P of the operational parameter during the flushing time TR exceeds the absolute value of a first unfastening limit PL1.

Abstract: A plant and method for controlling such a plant suitable for treatment of waste water. The plant includes a basin, a flow generating machine adapted to generate a liquid flow in the basin, equipment in the basin that effects the momentum of the liquid flow, and a control unit. The method includes the steps of: storing a predetermined relationship between the operational speed N of the flow generating machine and an operational parameter P from which the torque M of the flow generating machine may be derived, determining the operational speed N, determining a set value of the operational parameter P of the flow generating machine, determining a real value of the operational parameter P of the flow generating machine, and adjusting the operational speed N if the real value of the operational parameter P is different than the set value of the operational parameter P.
