Abstract: A portable vacuum loadable 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 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 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: There is provided a screening panel having screening apertures and which can be secured to a support frame side-by-side with similar panels to form a screen deck. The panel has ridges along two of its sides which project above the screening surface. The ridges form a channel which confines liquid flowing across the screen deck to flow across the screening apertures. Grooves extend through the ridges to direct liquid flowing across the screen deck directly into the screening apertures.

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。

Abstract: A saturated layer stormwater filtering system with down-flow layered multimedia filters is disclosed. The filtering system may include an upflow pretreatment chamber and a subsequent filtration chamber. It also includes a snorkel pipe as an adjustable head control or internal baffles. The system incorporates gravity powered partially saturated stormwater media filters to harness the potential energy of stormwater from downspouts and pumped flows from stormwater catchments to drive the polluted stormwater in a hydraulically controlled fashion by gravity through a series of filter media layers.

Abstract: A rotary distributor speed control system that uses hydraulic forces is provided. This rotary distributor speed control system is part of a trickling filter used in wastewater treatment. The trickling filter includes a tank which is filled with a porous filter media, a center column that extends through the center of the tank and holds a feed pipe through which influent wastewater flows, and distribution arms that extend radially from the center well. Each distribution arm has a forward side and a reverse side. The forward side and the reverse side each define at least one orifice. Slide gates are coupled with the distribution arms, and these gates can be moved so as to cover the orifices. A slide gate valve operator is also coupled with each arm for mechanically moving the slide gates in response to a change in influent feed flow, a change in arm speed, or external conditions.
