Abstract: A filter apparatus (10) has a plurality of filter elements (20) in a filter housing (12) having a filter inlet (50) for a fluid to be filtered and a filter outlet (52) for the filtered fluid. A pressure control device (42) has at least one control plate (58) located inside a connection chamber (14). The control plate laterally passes over individual upper element openings (54) of the filter element to be backwashed (20), in a predefinable sequence, covering the opening to an increasing degree and then exposing the opening again. A discharge opening (46) of the backwash device (44) is, at least in part, fluidically connected to a lower element opening (56) of the filter element (20) to be backwashed, as the pressure control device (42) moves towards the upper element opening (54).

Abstract: The present invention relates to a system and a process of running the system that allows for the long term filtration of product without loss of filtration capability due to clogging or fouling. The system is a normal flow filtration system having one or more filter cartridges attached to an outlet of a housing in the system. The filter cartridge(s) are contained within a bowl and depend preferably vertically from the outlet. Liquid enters the bowl of the housing and contacts the outer surfaces of the one or more cartridges. Impurities are trapped on or in the surface of the filter and the filtered liquid flows through the filter and through the outlet. One or more parameters such as flow rate, transmembrane pressure drop and/or time are measured and when the desired parameter(s) are met, the filtration ceases. A backflushing occurs back through the filter cartridges so as to remove the trapped impurities on or in the filter surface. This backwashed material is directed to an outlet of the bowl that is connected to a drain. Additionally a port formed in the side of the housing adjacent an outer surface of the cartridge(s) can be used to provide a lateral washing of the filter surfaces. The system is then recirculated in a downstream manner to reestablish equilibrium and filtration is the restarted.

Abstract translation: 本发明涉及运行该系统的系统和方法，其允许产品的长期过滤，而不会由于堵塞或结垢而丧失过滤能力。 该系统是具有连接到系统中的壳体的出口的一个或多个过滤器滤芯的正常流量过滤系统。 过滤器滤芯被容纳在碗内并且优选地垂直于出口。 液体进入壳体的碗中并接触一个或多个盒的外表面。 杂质被捕获在过滤器的表面上或其中，并且过滤的液体流过过滤器并通过出口。 测量一个或多个参数，例如流速，跨膜压降和/或时间，并且当满足期望的参数时，过滤停止。 反冲洗通过过滤器滤芯，以便去除过滤器表面上或过滤表面上的被捕获的杂质。 该反冲洗的材料被引导到连接到排水管的碗的出口。 另外，形成在壳体的邻近盒的外表面的一侧的端口可以用于提供过滤器表面的侧向洗涤。 然后将该系统以下游方式再循环以重新建立平衡，并且重新开始过滤。

Abstract: A device for the collection of water from a granular material bed filter includes means for injecting water and air through the filtration bed as well as an outer chute provided with a weir for the discharge of water, characterized in that it is made of a storage capacity placed between the filter and the discharge chute and defined by a vertical perforated wall such as a grid situated in vertical alignment with the filter vertical wall, and a plane slanting inwardly to the inside of the filter, said slanting plane connecting the weir for the discharge of the water via the chute to the filter wall situated below the vertical perforated wall such as the grid.
