    Abstract: A method and a filtration system filter liquids and/or melts. The filtration system includes a housing with a supply channel, a discharge channel and a first and second filter device. Each of the filter devices has a filter element passed through a filter chamber, which is held clamped by clamping devices. Each of the clamping devices includes interacting clamping elements and actuating elements, wherein the clamping elements are guided in a normal direction onto a flat side of the respective filter element in an adjustable manner relative to the housing. Clamping element contact surfaces and actuating element contact surfaces are respectively aligned opposite to one another and have an oblique longitudinal alignment with respect to the flat side of the respective filter element.

    Abstract: An apparatus for filtering and degassing a plastic melt, in particular of a thermoplastic plastic melt, comprising a feeding extruder (11) which comprises at least one extrusion worm (13) which is rotatable in a housing, wherein the feeding extruder opens into the feeding region of one or several parallel melt filter modules (31) and a discharge extruder (21) with at least one extrusion worm (23) is situated in the discharge region of the melt filter(s), said discharge extruder being operated in the opposite direction of the feeding extruder in such a way that the worm tip (24) acts as the intake zone and the region near the drive acts as the discharge zone, wherein, for discharging the melt, a discharge aperture (27) in the housing is provided before the drive (22) of the discharge extruder, wherein the shaft of the extrusion worm of the discharge extruder is sealed against the drive of the discharge extruder with a sealing element (26) and wherein the feeding extruder opens into melt valves (25) and/or melt deflectors which are upstream of the melt filter, and, in the discharge region of the melt filter(s) and downstream of the melt filter, melt valves (25) and/or melt deflectors are provided, subsequent to which the discharge extruder is situated and the worm tips are mounted.
