摘要： A filter module according to the present invention comprises a housing having an inlet and an outlet, said housing enclosing a tubular, elongate filter element defining a longitudinal axis and a cleaning head connected by means of a conduit to a coaxially arranged and rotatably mounted pipe, said cleaning head being resiliently biased towards the internal surface of said tubular, elongate filter element. Moreover, said cleaning head has an opening of adjustable size facing said internal surface of said filter element and providing fluid communication between the interior of said housing and the interior of said pipe. The filter module further comprises means for creating a pressure difference between the interior of said housing and the interior of said pipe so as to cause a fluid flow from the interior of said housing to the interior of said pipe as well as means for effecting a rotation of said pipe. Said filter module further comprises a spacer element rotatably supported on and releasably attached to said cleaning head, said spacer element defining the minimum spacing between the cleaning head and the internal surface of said filter element.

摘要： The present invention relates to filtration of liquids, such as water, containing substances that desirably should be removed from the liquids. The invention relates in particular to a filtration cake, being produced in situ of a cleaning system from substances that desirably should be filtered away. Particular preferred embodiments of the present invention relate to treatment of waste water, where an activated sludge is provided, which sludge contains activated sludge flocs. These flocs are accumulated on a fluid penetrable support structure to form a layer of flocs, which subsequently is compressed to form a filter of desired properties. The invention also relates to adapting waste water—or other liquids containing biodegradable substances—to optimised biodegradation and filtration by deflocculating flocs in an activated sludge during or before a biodegradation step and subsequently promoting re-flocculation prior to filtering or other means of biomass separation.

摘要： In a preferred embodiment, a rotary filter or dewatering device having a conical shape in which the precoat is on the inside of the conical filter, and in which pressure within the cone and/or vacuum on the outside surface of the conical filter creates a differential pressure causing a feed within the conical filter to be filtered through the filter, and the filtrate to be collected outside of the conical filter. A revolving knife having a spiral contour and being concentric to the conical filter, fractionally advances axially into the conical filter at a predetermined rate to cut away a surface layer of the precoat, the spiral contour serving also to force the sludge of filtered solids to an outlet from said conical filter. The invention also includes the process of precoating, filtering under a differential pressure, and cutting away the precoat from within the conical filter.

摘要： A self-purging filtering apparatus having a pressure vessel connected for discharging clean filtrate to subatmospheric pressure at a pump inlet. Actuators connected to an outwardly extending rod move a wiper piston to scrub the upstream side of an annular filter media element. The piston moves a main valve member to isolate a purge chamber from the filtering chamber. Remotely operated valves control flushing of the purged chamber. The main valve has a bleed valve to provide pressure equalization for facilitating main valve movement.

摘要： By this method, the fluid to be filtered is led through a filter bed formed of particulate filter particles, such as sand, which filter bed is retained in an upstanding annular space. The fluid is introduced to the interior part 15 of the annular space and is led transversely to the movement the filter bed, through it and away. The filter bed is provided on the inner wall of annular space with a microfilter, such as sieve grid 16, with a mesh size of 10 to 200 microns, whereby the heavy and flocculated dirt particles settling upon the microfilter are led down and away and are drawn off together with the particulate filter particles 32. To avoid stoppages of the microfilter, it is flowingly hydraulically cleaned from the inner space. Additionally, by introduction of water in the take-off space 11 there is produced a vortex bed, whereby at this space the withdrawal of the particulate filter medium is effected with a mammoth pump 17 known per se. The compressed air for the operation of the mammoth pump 17 is supplied not steadily but pulsatingly. Thus, there are provided in the vortex bed in combination with the water supply thereto some hydraulic pulses which serve to hinder the development of bridges in and above it.

摘要： A cylindrical wash flow fuel filter element is mounted in a housing so as to form a flow recirculation path, a portion of which is parallel to the surface of the filter. Fluid enters an inlet and passes through a jet inducer nozzle which accelerates the fluid inducing a flow in the recirculation path. Contaminants are washed away from the surface of the filter and held in suspension by the wash flow in the recirculation path. One of two outlets receives filtered fluid which passes through the filter element. The other outlet communicates with the recirculation path via a pressure responsive shutoff valve. An auxiliary check valve limits the pressure drop across the jet inducer nozzle for high inlet flow conditions. When the pressure responsive shutoff valve is closed, filtered flow equal to that entering the jet inducer emerges radially from the wash flow filter and the contaminant is, for a limited time, stored in the recirculating wash flow path. When the pressure responsive shutoff valve is opened the wash flow passes through the other outlet thereby discharging the stored suspended contaminants.
