摘要： An improved underdrain block for an underdrain system supporting a filter media bed in a liquid filtration system is provided. The underdrain blocks are preferably made of an extrudable polymeric material that is extruded in relatively long sections to provide light weight, strong, easily manufactured underdrain systems having a lower profile than prior art underdrain blocks. The underdrain block comprises an upper wall, side walls, a lower wall, at least one lateral member between the upper wall and the lower wall, at least two chambers within the underdrain block, each chamber being defined by the lateral member, a plurality of upper orifices in the upper wall of the underdrain block, and a plurality of internal orifices in the lateral member. The underdrain block is substantially greater in longitudinal length than a longitudinal distance between the upper orifices. In one embodiment, the underdrain block has rails situated on the upper wall for engaging extruded members, which in turn, have receiving recesses for receiving a layer of porous filter media. In another embodiment, the underdrain block further comprises an air nozzle for achieving an improved distribution of air through a filter bed during air backwashing.
摘要翻译： 提供了一种用于在液体过滤系统中支撑过滤介质床的缺油系统的改进的漏液块。 欠划线块优选地由可挤出的聚合物材料制成，该材料在相对较长的部分中被挤压，以提供比现有技术的下划线块更低的轮廓的重量轻，强而易于制造的下划线系统。 下划线块包括上壁，侧壁，下壁，在上壁和下壁之间的至少一个侧向构件，在下划线块内的至少两个室，每个室由侧向构件限定，多个 漏斗块的上壁中的上部孔，以及侧面构件中的多个内部孔。 纵向长度小于上部孔口之间的纵向距离，下划线块的距离大大增加。 在一个实施例中，下划线块具有位于上壁上的轨道，用于接合挤压构件，其又具有用于接收多孔过滤介质层的接收凹部。 在另一个实施方案中，下划痕块还包括空气喷嘴，用于在空气反冲洗期间实现空气通过过滤床的分布。

摘要： An apparatus for removing material collected in a material collection container having a floor and at least one substantially vertically extending wall. The apparatus includes a material removal assembly for removing material collected in the material collection container. The material removal assembly includes a first conduit and a second conduit. The first conduit is in telescoping relationship with the second conduit to permit the first conduit to move relative to the second conduit. The first conduit and the second conduit each have a longitudinal axis. The material removal assembly further includes at least one material removal header configured to receive material accumulating on the floor of the material collection container. The material removal assembly is preferably configured to enhance numerous aspects of the sludge removal process.

摘要： A filter system having a filter bed for filtering water or wastewater, where the filter bed is periodically washed between service runs by directing washing liquid and washing gas upwardly through the filter bed. The filter system includes a filter bed and at least one flume. The flume is in fluid communication with the filter bed. Preferably, the flume is configured such that no washing liquid and washing gas interface is present in the flume. The flume may be configured such that during washing of the filter bed between service runs the flume receives a washing gas and directs the washing gas upwardly through the filter bed to assist in cleaning the filter bed between service runs. The flume may further be configured such that during washing the only liquid directed from the flume to the filter bed is residual liquid that may be present in the flume from a prior service run.
