A filtration element comprising a thread-based medium comprising one or more threads, wherein each thread comprises at least one filament of carbon nanotube (CNT), and wherein the filtration element is configured to filter a feed fluid based on a filtration operation wherein the feed fluid passes through the thread-based medium.

The invention relates to a device for the microfiltration, ultrafiltration, or nanofiltration and/or the emulsification of liquids. The device has at least one rotatable membrane medium, which has a filtrate/permeate side or a side facing a dispersed phase and a concentrate/retentate side or a side facing a coherent phase and which can be rotated in a container in order to produce a vacuum on an unfiltered liquid side or the side facing the coherent phase on partial regions of the at least one rotatable membrane medium in the container in small time segments at a frequency of 1-100 Hz. Said container has at least one feed for an unfiltered liquid or the coherent phase, at least one overflow for an unfiltered liquid or an emulsion, and at least one rotatable channel for filtrate/permeate drainage or feed of the dispersed phase, and a suction device, in particular in the manner of a suction strip or nozzle plate. The suction device has at least one suction strip or nozzle plate arranged parallel to the rotatable membrane medium or is such a suction strip or nozzle plate, which is attached at a distance of less than 0.1 to 10 mm from the membrane medium, and thus cleans non-permeating materials collected on the unfiltered liquid side during a filtration process from a surface of the membrane medium, or promotes drop formation of the dispersed phase exiting from a membrane surface on the side facing the coherent phase during an emulsification process. The invention further relates to uses of the device.

A filter sector assembly for a disc filter, which disc filter has a fiber suspension containing bath and a core assembly adapted to rotate on a horizontal axis. The filter sector assemblies are rotatably supported with relation to the bath on the core assembly. The filter sector assemblies are spaced along the core assembly and supported on the core assembly. Each filter sector assembly (50) has two adjacent filter sectors (10A; 10B) releasably fixed to a bent support plate (30). The two adjacent filter sectors (10A; 10B) are attached as a pair of filter sectors (10A; 10B) by fastening the support plate (30) to the core assembly (21; 21A, 21B) of the disc filter.

A ceramic filter plate (22) is provided with a conductive wiring (70, 71) extending along the filter plate to form a continuous electrical circuit and arranged to break upon breakage of the filter plate. The integrity of the conductive wiring (70, 71) is monitored, and the operation, particularly the rotation, of the disc filter is immediately stopped upon detecting a break of the conductive wiring.
