摘要： Die Drainagerohre (2) sind über Tauch- oder Anschlussrohre (5), die durch den Filterboden (13) hindurchführen, mit einem unter dem Filterfeld (1) angeordneten Sammelkanal (4') für das Reinwasser verbunden. Es sind in den Tauchrohren (5) und in den Filterdüsen (15'), die in die Drainagerohre (2) eingesetzt sind, Lufteintrittsöffnungen (9 bzw. 17) vorhanden, um die Ausbildung eines doppelten Luftpolsters (10 bzw. 11) zu erreichen und so eine gleichmäßige Verteilung der Spülluft vor ihrem Austritt in die Filtermasse in Längsrichtung und in Querrichtung des Filterfeldes (1) zu gewährleisten; auf diese Weise wird eine gleichzeitige und gleichmäßige Luftspülung über die ganze Fläche des Filterfeldes (1) sichergestellt.

摘要： The invention relates to a filter device comprising a filter housing (1) for a filter medium made of fiber material (2). The filter housing (1) has an inlet for a liquid to be filtered and a suction opening (8) for the filtered liquid. According to the invention, the filter housing (1) is divided into a suction-side pre-chamber (5) and an inlet-side filter chamber (6) by means of an inner separating plate (4) which is provided with passage openings (11) for the liquid. The pre-chamber (5) has a cross-section which is expanded compared to the suction opening (8) or which expands from the suction opening (8) to the separating plate (4), and the filter chamber (6) is filled with the filter medium made of fiber material (2) and has the inlet. The filter chamber (6) allows a secure and dimensionally stable receiving area for the fiber material (2). By using the embodiment according to the invention, the risk of the filter medium being pressed and compressed is reduced.

摘要： A water filtration apparatus has at least one tank in fluid communication with a conduit through at least one aperture in a wall. Each tank uses filter blocks to support the filter medium and to direct the filtered water to the conduit via the aperture. An end plate for the filter block is provided, the end plate being adapted to seal against a free end of the filter block. The end plate also provides apertures for fluid flow into and out of the filter block, and a device for receiving a sealant to provide a seal between the end plate and the wall. The end plate improves the installation of the apparatus, and the sealant improves the reliability of the seal round the apertures, which in turn improves the efficiency of a backwash operation used to clean the filter medium.

摘要： A filter system for filtering water and/or wastewater which includes an underdrain system having a plurality of laterals that are anchored to the floor of a filter by a hold-down assembly. Preferably, the hold-down assembly does not rely on grout or other substance that is applied in a viscous or semi-viscous state and subsequently hardened as the primary means for connecting the underdrain laterals to the floor of the filter. Preferably, the hold-down assembly includes hold-down clips that can move relative to an anchor assembly and corresponding underdrain blocks so that the hold-down clips can cooperate with any desired portion of the corresponding underdrain blocks.
