Abstract: A system which separates suspended substances from a liquid with a cyclone filter assembly that is rotationable symmetrically about a longitudinal axis. The invention is has a filter element with a filter wall configured as a single-layered perforated sheet with perforation holes having a hole diameter ranging from 5 µm to 80 µm inclusive at a radially outer filter wall surface with sensors for measuring a pressure difference between the filtrate chamber and a separation. A respective shut-off valve is located along first and second discharge lines, and a control actuates at least one of motor and at least one shut-off valve as a function of the pressure difference.

Abstract: Described is a screw filter press comprising a screw shaft, which has at least one coil turn and two screw shaft ends, the shaft axis of which is oriented parallel to the gravity vector and which is supported on one side via the upper screw shaft end thereof and which is connected to a rotary drive, and which is enclosed coaxially, at least in its lower partial area in a so-called filter area by a cylindrical filter tube, which is provided with openings and at which a filtrate space adjoins radially, to which underpressure can be applied.

Abstract: A cyclone separator includes a housing generally symmetric about its central longitudinal axis and an inlet for introduction of a fluid containing dispersed substances. An outlet for the cleaned fluid includes a tube through the bottom wall of the housing having an axis coaxial with the longitudinal axis. An outlet for the dispersed substances has the shape of an annular channel in the bottom wall disposed adjacent the tube and adjacent a rotation axis of the fluid whereat high-density substances settle.

Abstract: A cyclone separator includes a housing generally symmetric about its central longitudinal axis and an inlet for introduction of a fluid containing dispersed substances. At least a portion of the housing wall is shaped to form a flow rectifier. An outlet for the cleaned fluid comprises a tube through the bottom wall of the housing having an axis coaxial with the longitudinal axis. An outlet for the dispersed substances has the shape of an annular channel in the bottom wall disposed adjacent the tube and adjacent a rotation axis of the fluid whereat high-density substances settle.

Abstract: The present invention relates to a gully emptier comprising a container which has connected thereto a water jet or vacuum/pressure pump for conveying slurry and in which a discharge pipe which is provided with a filter at a liftable and lowerable end is arranged upstream of the connection to the suction side of a low-pressure pump, wherein a float is connected to the filter. Thanks to the float which floats on the water surface, the filter is automatically held at a predetermined depth below the water surface even when the water level changes. A manual adjustment by the operating staff is no longer required. The distance of the filter from the water surface can be accurately adjusted by using a floodable or inflatable float.
