    Abstract: The filter device is utilized for the separation of undissolved solid substances from liquids, in particular in the fields of waste water purification and water treatment. The filter device is arranged in a container as capable of rotation (2) and surrounded by the liquid to be filtered. The filter device (1) consists of several filter elements (6) with a space between one another, which are combined to form a rotating filter. The filtrate is drained away at the periphery of the filter elements (6). Solid substances are prevented from adhering to the filter elements (6) during the filtering process. The rotating filter comprises a hollow space in the center and an aeration device (8) is arranged in the hollow space, around which the filter device rotates. The filters are continuously cleaned by the mixture of air and liquid flowing through during the filtering process.

    Abstract: An apparatus for filter backwashing includes a vessel containing a bed of filter media. Laterals with nozzles are disposed below the filter media to convey backwashing air and water into the filter bed. Below the laterals are located a manifold and a distribution plenum to carry air into the laterals. The manifold and the distribution plenum are separated by a common wall having a plurality of ports to provide communication therebetween. Communication between the distribution plenum and the laterals is provided by a plurality of conduits, one conduit extending into each lateral from the distribution plenum.

    Abstract: Pre-cast concrete beams for supporting a filterbed have deep downwardly extending flanges for providing an underchannel lengthwise of the beam. The beams generally extend across a flume. For backwashing with an air-water mixture, air should be supplied at substantially the same rate to all of the channels. Cross passages between the channels are an aid to this even distribution. Heretofore, special molding procedures for providing the passages or limbers through the beam flanges have increased manufacturing costs. According to the present invention, such passages are provided without extra molding steps and without extra cost by following a delightfully simple concept of merely omitting the end portions of the flanges where beam strength is not required. The end portion projecting beyond the flanges may have a leg across its end to ensure support and aid sealing.

    Abstract translation: 用于支撑滤床的预制混凝土梁具有深的向下延伸的法兰，用于在梁的纵向方向上提供低通道。 梁通常延伸穿过水槽。 对于使用空气 - 水混合物进行回洗，应以基本相同的速率向所有通道提供空气。 通道之间的交叉通道是对这种均匀分布的帮助。 迄今为止，用于通过梁法兰提供通道或混凝土的特殊的成型程序增加了制造成本。 根据本发明，这种通道在没有额外的模制步骤的情况下被提供，并且通过遵循仅仅省略不需要束强度的法兰的端部的令人愉快的简单概念而不需要额外的成本。 突出超过凸缘的端部可以在其端部上具有腿部以确保支撑和辅助密封。

    Abstract: A filtration system for liquids employs a sealed tank that is partially filled with sand or the like to provide a filtration bed in the lower portion thereof. An underdrain device is buried in the bed of sand and prevents particles from passing outwardly from the bed with the liquid flowing through the system. One end of a vent conduit is attached to the underdrain device from which it passses upwardly through the sand to a point near the top of the tank. Air introduced into the tank escapes automatically through the vent conduit, thus eliminating the need for the valves which are conventionally provided in the upper portion of such tank filters for the same purpose. The filtration system includes a particulate or sand filter unit coupled with a fabric type filter to remove very fine particles from the liquid removed from the liquid treated in the sand filter unit. The system is particularly adapted for use with swimming pools, and is capable of removing very fine particles from water flowing at high rates through the system.

    Abstract translation: 用于液体的过滤系统采用部分填充有砂等的密封罐，以在其下部提供过滤床。 漏水装置被埋在沙床中，并防止颗粒从液体向外流出，液体流过系统。 通气管道的一端连接到下划线装置，从该管道向上通过沙子到靠近罐顶部的点。 引入罐中的空气通过排放管道自动逸出，从而消除了为了相同目的而通常设置在这种罐式过滤器的上部的阀的需要。 过滤系统包括与织物型过滤器结合的颗粒或砂过滤器单元，以从从砂过滤单元中处理的液体中除去的液体中除去非常细的颗粒。 该系统特别适用于游泳池，并且能够通过系统从高流量的水中除去非常细小的颗粒。
