Publication number: 20120234747Abstract: The filter device is utilized for the separation of undissolved solid substances from liquids, in particular in the fields of waste water purification and water treatment. The filter device is arranged in a container as capable of rotation (2) and surrounded by the liquid to be filtered. The filter device (1) consists of several filter elements (6) with a space between one another, which are combined to form a rotating filter. The filtrate is drained away at the periphery of the filter elements (6). Solid substances are prevented from adhering to the filter elements (6) during the filtering process. The rotating filter comprises a hollow space in the center and an aeration device (8) is arranged in the hollow space, around which the filter device rotates. The filters are continuously cleaned by the mixture of air and liquid flowing through during the filtering process.Type: ApplicationFiled: June 1, 2012Publication date: September 20, 2012Applicant: UTISOL TECHNOLOGIES AGInventors: Eberhard Harms, Mark Grigo

Patent number: 7918348Abstract: In a filter device and in a method for the periodic cleaning of a filter of a water treatment or sewage treatment plant, a rotating filter is arranged within its own separate filter chamber, the bottom of which is designed as following a contour of the rotating filter. The provision of an own separate filter chamber makes it possible for the rotating filter to be cleaned, without other parts of a filtering installation having to be taken out of operation, and without the rotating filter having to be dismantled and removed from the filter chamber. Therefore no lifting cranes or separate cleaning basins are necessary.Type: GrantFiled: April 23, 2004Date of Patent: April 5, 2011Assignee: Utisol Technologies AGInventors: Eberhard Harms, Mark Grigo

Patent number: 7678273Abstract: A filter unit includes membrane plates placed together parallel to one another, which at least in zones around connecting elements for the purpose of draining permeate are connected together liquid-tight. The membrane plates because of their shape and after two membrane plates have been placed one on top of the other are provided for manufacturing a liquid-tight connection or a seal by welding. As a result unfiltered liquid flows through between the membrane plates and contamination of the permeate within a volume situated between the connecting elements is prevented. Over a number of connecting elements and zones located in between it is possible to attach a hollow profile, which is closed-off at its ends. This hollow profile in a liquid-tight manner surrounds discharge openings of the connecting elements and the zones located in between with positive material engagement.Type: GrantFiled: May 7, 2004Date of Patent: March 16, 2010Assignee: Utisol Technologies AGInventors: Eberhard Harms, Mark Grigo

Patent number: 7332081Abstract: A filter device for the clarification of contaminated liquids includes a vessel configured to contain the liquid to be clarified. A first carrying disk is arranged within the vessel and is rotationally driven about a rotational axis. Mounting rods are attached to and extend generally perpendicular from the carrying disk. A plurality of filter modules including spaced apart filter elements extend generally parallel to the carrying disk. Each of the filter modules is rotationally fixed relative to the carrying disk at least in part by the mounting rods. The filter modules have a radially inward end spaced radially from the rotational axis of the carrying disk. The ends of the filter modules circumscribe a cavity within the vessel having a longitudinal axis corresponding to the rotational axis of the carrying disk. The cavity is configured such that a cleaning fluid medium from within the cavity flows radially out from said cavity and between the filter elements to clean the filter elements.Type: GrantFiled: January 16, 2006Date of Patent: February 19, 2008Assignee: Hans Huber AGInventors: Eberhard Harms, Mark Grigo

Patent number: 7037427Abstract: A filter device for the clarification of contaminated liquids includes a plurality of disk-shaped filter elements spaced apart from one another and combined into circular or polygonal filter modules. The filter elements are arranged rotatably about a horizontal axis in a vessel containing the unclarified liquid. The filtrate is capable of being discharged via the individual filter modules. The filter modules form centrally a cavity. The cavity on one side is closed by a carrying disk and on the other side is connected to the vessel via a suction-intake orifice. The cavity is connected operatively to a flow member in such a way that, via the suction-intake orifice, a flow can be generated in the unclarified liquid between the spaced-apart filter elements and avoids an adhesion of solids to the filter elements.Type: GrantFiled: April 19, 2001Date of Patent: May 2, 2006Assignee: Hans Huber AG Maschinen-und AnlagenbauInventors: Eberhard Harms, Mark Grigo

Publication number: 20030164327Abstract: The filter device (1) is especially used for mechanical cleansing of waste water and for water treatment. It is rotationally arranged in a container (2) and surrounded by the liquid to be filtered The filter device (1) comprises several filter elements (4) which arc arranged at a distance from each other, form segment-shaped filter modules (3) and are assembled to form a rotary filter. The individual filter elements (4) consist of filter plates which are used to divert the filtrate and which are provided with filters on both sides. The aim of the invention is to prevent solids from adhering to the filters during the filtering process. This is achieved by providing the rotary filter with a hollow area (14) that is connected to the container (2) via a suction inlet and which is scaled by means of a carrier plate (6) for the filter segments, and also by making the hollow area (14) cooperate with a now member. A pump blade wheel is used as a flow member.Type: ApplicationFiled: January 14, 2003Publication date: September 4, 2003Inventors: Eberhard Harms, Mark Grigo
