Abstract: The application concerns a control unit (1) and its for positioning a wash-down hose (2) with flushing nozzle (3) for cleaning of waste-water pipes, in which the wash-down hose (2) is mounted on a cylindrical wash-down hose drum (4) with an axial length and where the wash-down hose drum has a rotational position, wherein the unit includes a pulse emitter (5), a rotation direction indicator (5a) and a memory unit (6), in which: - the pulse emitter (5) is designed for emitting a fixed number of electrical pulses per rotation of the wash-down hose drum (4), - the rotation direction indicator (5a) is designed to determine a rotation direction for the wash-down hose drum (4), and - the memory unit (6) is designed with an address for storing data related to the electrical pulses from the pulse emitter (5) and from the rotation direction indicator (5a) for determining the rotational position of the wash-down hose drum (4), where the storing of data is maintained independently from power supply to the memory unit (6). With the control unit an improved control is achieved of a flushing process of a waste-water pipe.

Abstract: The present invention relates to a method and apparatus for expelling liquid from liquid- containing materials, e.g. dewatering of sludge, by using a piston filter. The filter gaps on the pressure surface of the piston, are arranged to be self -cleaning, by the movement of the gap filter relatively to several fastened pins that clean the gaps . The apparatus may be mounted on a gully-emptier.
