AI Technical Summary

Problems solved by technology

When the membrane spacing is too small, the intensity of the purge flow is not sufficient over the entire surface of the filter, resulting in clogging
The strength of the filter cartridge can be increased by using spacer bars across the surface of the filter membrane, but this impairs cleaning of the filter membrane to filter-inhibit deposits
[0019] Another problem associated with this upward airflow is that due to these fluctuations in the membrane spacing, the filter membrane layers are damaged due to scratches and tears, resulting in a shortened life of the filter membrane

Abstract

A filter element comprising (i) an integrated permeate channel membrane (4) which has a flexible structure and comprises an upper and lower membrane layer and a substrate material for supporting said membrane layers, wherein said substrate is a 3D spacer fabric having an upper and a lower fabric surface, tied together and spaced apart by monofilament threads at a predefined distance and (ii) a frame system supporting said membrane and sealing said integrated permeate channel at the edge of the membrane, said frame system comprising a first frame profile and a second frame profile each of them having form and dimensions capable of surrounding the membrane, wherein each of said first and second frame profile has inner parts and outer parts wherein said membrane (4) is interposed between said first frame profile and said second frame profile. A filter module comprising a plurality of filter elements is also provided.

Description

technical field [0001] The present invention relates to a filter element comprising a one-piece permeate channel membrane, and a frame system supporting the membrane and sealing the one-piece permeate channel at the edges of the membrane. The invention also relates to a method of manufacturing the filter element and a filter membrane module comprising a plurality of the filter elements. Background technique [0002] In recent years, much attention has been paid to membrane bioreactors (MBRs) in the water field. MBR combines two basic processes—biodegradation and membrane separation—into a single process, in which the microorganisms responsible for biodegradation and suspended solids are separated from the water being treated by a membrane filtration unit. Research so far has focused on the application of MBR to domestic, industrial and mixed domestic and industrial wastewater treatment plants, concentrated streams from industrial processes, treatment of seepage water from w...
