Patent number: 5628903Abstract: The invention relates to an apparatus for the removal of clarified waste water from circular tanks which have a central waste-water inlet. It is notable for a submerged pipe which is constructed as a ring conduit provided concentrically with the vertical axis of the ring tank and is arranged underneath the surface of the clarified waste water in order to draw off the clarified waste water uniformly, the drainage of the latter being regulatable independently of the incoming amount by means of a control system and the water level in the tank being controllable in a constant manner by means of said system.Type: GrantFiled: June 13, 1995Date of Patent: May 13, 1997Assignee: Hans Huber GmbH & Co. KGInventor: Franz Valentin

Patent number: 5464542Abstract: A method for filtering and backwashing solid particles out of liquids is illustrated, with a filter drum (5) positioned completely below the liquid level (6) having a cylindrical surface (7) coated with a filter medium (8), the liquid flown through the outside of the filter drum to the inside. A backwashing device for removal of the filter cake from the filter medium is provided. At the beginning of each cycle of backwashing an air cushion (15) is introduced in the filter drum (5) and liquid in the filter drum (5) is displaced in such a manner so that liquid jets from an ejetion apparatus (19) containing a spraying head (17) and being arranged in the interior of the filter drum without being sealed on the filter drum penetrate through the air cushion (15) to the backside of the cylindrical surface (7) of the filter drum (5). The filter cake so removed from the filter drum is withrawn at the outside of filter drum (5) in a stream of liquid.Type: GrantFiled: November 16, 1994Date of Patent: November 7, 1995Assignee: Hans Huber GmbH Maschinen-und AnlagenbauInventors: Johann Grienberger, Rudolf Bogner, Christian Frommann
