Embodiment Construction

[0020] figure 1 An embodiment of a filter device according to the invention with a flat filter module 10 and a base housing 20 is shown in perspective. The flat filter module 10 comprises at least one filter flat element or a plurality of flat filter elements 11 spaced parallel to one another and a module frame consisting of two end plates 13 and four frame bars 14 .

[0021] The flat filter element 11 comprises a drainage layer which is enclosed between two outer filter membranes and is adhesively bonded to the respective filter membranes on both sides over a large area. The drainage layer expediently comprises one or more fabrics made of yarns, filaments or wires made of polymers and / or metals, one or more non-woven fabrics made of polymers, or the fabrics and A combination of nonwoven fabrics. Preferably, the drainage layer is formed as a spacer knit.

[0022] The individual filter membranes can be joined to the drainage layer over the entire surface, point by point or l...

Abstract

The invention relates to a filtration device comprising a flat filter module (10) and a base housing (20), on which the flat filter module is placed. A wall (21) of the base housing (20) comprises a polymer cellular lightweight construction material, or a fiber composite material.

Description

technical field [0001] The invention relates to a filter device for microfiltration, ultrafiltration and nanofiltration, which is based on planar filter elements. Background technique [0002] Conventional filter systems for sewage treatment comprise filter modules having a tubular or box-shaped housing, in which a plurality of planar filter elements are arranged in parallel and spaced apart from each other. The gaps between adjacent flat filter elements form flow-through channels. A liquid to be filtered, called feed liquid or retention, is introduced into the interior of the tubular or box-shaped housing via an inlet line or through holes in the housing wall, flows through the flat filter elements and passes through the drain pipe or other hole in the housing wall. The flat filter elements are designed as mats or boxes and comprise a flexible drainage layer or rigid drainage sheet surrounded on both sides by a filter membrane. The flat filter elements each have outlet o...
