Abstract:
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Anschwemmfiltration eines Unfiltrats, wobei die Anschwemmfiltration ohne Verwendung einer Voranschwemmung durch eine Beaufschlagung eines Filtermittels mit dem zu filtrierenden Unfiltrat durchgeführt wird.
Abstract:
Multi-core solid profile filter media blocks include multiple sub-blocks, which may be formed by providing a block with multiple interior cavities extending deep into the block, to allow water to flow deep inside the filter block to access the media of the sub-block (in the case wherein the cavities are at the inlet to the block) or that allows water to be collected from each filtration sub-block (in the case wherein the cavities are at the outlet from the block). One or more indentations/spaces/gaps in the exterior surface of the block also may be provided to separate and extend between portions of the sub-blocks, so that substantially all of the filter media of a sub-block is accessible to fluid for filtration. This way, a filter block may include a large amount of media in a small cartridge or package volume, and the filter block may exhibit good flow distribution and low pressure drop. Sub-blocks of the filter block may be integrally formed together into the filter block, or may be directly connected, for example, preferably without any housing or internals clamping or fastening the sub- blocks together.
Abstract:
A cross-flow filter (1) with a plurality of filter inserts (4) through which flows a medium to be filtered achieves a long service life, thereby avoiding waste, if the filter insert(s) (4) are provided on their side faces (6) with a metal fabric.
Abstract:
A multi-stage, modular water filter apparatus having at least first (12) and second filter housings (13) engageable with one another, and each being engageable with a water inlet member (16), a water outlet member (14) and a fluid filter cartridge (150, 152) for removing undesired components in a water supply.
Abstract:
The invention relates to a process for filtering liquids containing solids by means of at least one filter surface (2). To prevent filter cake formation and clogging of the filter pores, the filter surface (2) is set in motion. Alternatively or additionally, a current with a velocity component of at least 0.1 m/s tangential to the filter surface (2) is set up in the liquid to be filtered.
Abstract:
A filtration vessel is provided with improved sealing surfaces and alignment methods. The sealing surface is provided by a perforated sleeve within the filtration vessel. An alignment mechanism is provided which allows for improved servicing of the filtration vessel.
Abstract:
A filtration array comprising a main raw fluid supply line and a main filtered fluid collecting line, at least one filtration flow path extending between the main raw fluid supply line and main filtered fluid collecting line, each at least one filtration flow path configured with a filtering assembly comprising a three or more filter units extending from a manifold configured on the filtration flow path and being in flow communication with the main raw fluid supply line and the main filtered fluid collecting line.
Abstract:
A filtration array comprising a main raw fluid supply line and a main filtered fluid collecting line, at least one filtration flow path extending between the main raw fluid supply line and the main filtered fluid collecting line; each of the at least one filtration flow path is configured with a filtering assembly comprising a pair of filter units coaxially extending from a common manifold configured on the filtration flow path and is in flow communication with the main raw fluid supply line and the main filtered fluid collecting line, each of the filter units comprising a plurality of parallely disposed filter members.
Abstract:
A filter assembly comprises a filter (10) defining path for fluid passing to or from the filter (10). An adaptor (11) is connected to the filter (10) and provides a continuation of the path. The adaptor (11) is for mounting the filter (10) on a mounting plate (12) and carries one or more sealing rings (30, 37) that are engageable with the mounting plate (12). The adaptor (11) is made from a plastics material and one surface of the adaptor (11) is reinforced by contact with an annular reinforcing member (31) which may be of metal, particularly steel. This allows the flow path provided by the adaptor (11) to be maximized.
