Abstract: A method of operating a large scale slow sand filter in a clean water treatment plant is described in which the surface of the sand bed (3) is covered by a series of overlapping thin, flexible, water permeable sheets (8) to form a protective filter layer (7) so that the Schmutzdecke forms on the protective layer (7) instead of on the surface of the sand. When the Schmutzdecke is to be removed, this is done either by removing it from the protective layer (7) in situ, for example by suction dredging, or by removing the individual sheets (8) of the protective layer together with the Schmutzdecke, from the filter. A clean protective filter layer is then formed on the surface of the filter bed for continued operation of the filter. If desired, several protective filter layers (7) may be provided one on top of the other so that it becomes unnecessary to instal a clean filter layer (7) each time one is removed in order to remove the Schmutzdecke formed during the previous operation run of the filter.

Abstract: A portable liquid-solid separator tank having a bed with a drain, surrounding sides and a dividing wall. A grate overlays the interior of the vessel, bed, and sides, and forms the dividing wall. A filter overlays the grate, extending up the sides and covering the top and the dividing wall. The separator, which may be vacuum loadable, is filled with a sludge which is then separated from the liquid it contains by gravity and hydrostatic pressure which force the liquid through the filter. Liquid is drained out of the bottom of the vessel and the solids are transported within the vessel. The solids are removed through a gate that may be provided in the tank, or by using a hydraulic lift system in much the same manner as a garbage truck empties a municipal dumpster. The filter is removed with the solids and usually discarded.

Abstract: A selectively removable gravitational and vacuum sludge filtration apparatus and method that provides for retrofit into a container and separation of the sludge solids from the sludge liquids therein. A pair of spaced vertically oriented filter assemblies each define a filtrate cavity therein and are connected by separator plates. The filter assemblies permit the flow of sludge liquids into the filtrate cavity, but not sludge solids. A separator divides each filtrate cavity into two cavity sections, a first filtrate cavity and a second filtrate cavity. Filtrate drains into first and second filtrate cavities by either vacuum or gravitational drainage, depending on the level of sludge within the container. Vacuum drainage occur in first or second filtrate cavity if either cavity is situated below the level of the sludge within the container. A first and second filtrate evacuation means provide for the evacuation of filtrate from the first and second filtrate cavities by the use of a vacuum pump. A set of fasteners hold the filter assemblies in the container and bias the filter assemblies against the container bottom. The fasteners may be released to provide for removal of the sludge filtration system from the container. Functionally applying this sludge filtration system provides a method of retrofitting a container with a sludge filtration system and removing filtrate from a sludge in the container.

Abstract: A sludge filtration system for separating the sludge liquids from the sludge solids. A container provides a basin for receiving and holding the sludge. Within the container, a first filter assembly, positioned proximal the container bottom, defines a first filtrate cavity. The first filter assembly is maintained below the sludge level so that a pump, in flow communication with the first filtrate cavity, provides for vacuum evacuation of the first filtrate cavity. Placing a valve in the first filtrate discharge conduit facilitates selective vacuum evacuation or gravitational evacuation of the first filtrate cavity. A second filter assembly extends about the inside perimeter of the container cavity proximal the container side walls. In addition, the second filter assembly extends from proximal the container bottom to the container top end. The second filter assembly defines a second filtrate cavity. A second filtrate discharge conduit provides for gravitational evacuation of the second filtrate cavity. Providing a valve in the second filtrate discharge conduit and providing a second pump in flow communication therewith facilitates selective vacuum evacuation or gravitational evacuation of the second filtrate cavity. Functionally applying the aforementioned apparatus having a sludge therein provides a method of dewatering sludge.

Abstract: A system for the rapid dewatering of sludge in large quantities makes use of a filter plate of design and construction capable of supporting heavy mechanized mobile equipment without damage to the filter media.The filter plate features a monolithic plate of granular filter material used as the filtering medium in sludge beds for dewatering or reducing residual solids or sludge of potable water treatment systems. The filter material is made structurally rugged and with a smooth hard surface for the retention of sludge solids. The filter material is supported upon a substructure of aggregate providing approximately 40% internal voids for the gravity flow or drainage of filtrate and the back flow of chemicals and gases used in the rapid water reduction process. The assemblage is constructed of such strength as to allow for use of heavy handling equipment such as front end loaders in the removal of the dried sludge or cake upon the completion of the rapid water reduction process.The process follows a cyclical pattern on adjacent sludge beds where raw sewage is pretreated with a polymer coagulant to break up solids and/or to flocculate the sludge particles and then spread on the filter bed as the filter bed is being filled. Large coagulated sludge particles gain weight as they settle, and water is drawn off by gravity while a bed is being filled to the desired designed level. Smaller sludge particles pass to the voids below by a vacuum of 10 to 15 inches when the vacuum is applied, to start the rapid dewatering process through the larger flocculated sludge particles. The mass may be periodically moved and heated while dewatering progresses. Upon completion of dewatering, one or more units of fron end loading equipment is used to move the dried sludge cake into heaps and load it into trucks for transport to disposal sites.
Abstract translation: 用于大量污泥快速脱水的系统使用能够支撑重型机械化移动设备而不损坏过滤介质的设计和结构的过滤板。 过滤板具有颗粒过滤材料的整体板，用作污泥床中的过滤介质，用于脱水或减少残留固体或饮用水处理系统的污泥。 过滤材料结构坚固，具有光滑的硬表面，用于保留污泥固体。 过滤材料支撑在骨料的底部结构上，为重力流动或滤液排放提供大约40％的内部空隙，并且在快速减水过程中使用的化学物质和气体的回流。 该组合体具有这样的强度，以便在快速减水过程完成时允许使用诸如前端装载机的重型搬运设备来去除干燥的污泥或滤饼。 该过程遵循相邻污泥床上的循环模式，其中原料污水用聚合物凝结剂预处理以分解固体和/或絮凝污泥颗粒，然后在过滤床被填充时扩散在过滤床上。 大型凝结污泥颗粒在沉降时获得重量，并且当床被填充至所需设计水平时，重力将水排出。 当施加真空时，较小的污泥颗粒通过10至15英寸的真空下降到下面的空隙中，以通过较大的絮凝的污泥颗粒开始快速脱水过程。 当脱水进行时，质量可以周期性地移动和加热。 脱水完成后，使用一台或多台前端装载设备将干燥的污泥块移动到堆中，并将其装载到卡车中运输到处置场所。
