摘要： 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.

摘要翻译： 本发明涉及一种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滤芯的正常流过滤系统。 滤筒被包含在碗内，并优选地垂直于出口。 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表面上，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，形成在壳体的与盒的外表面相邻的一侧的端口可以用于提供过滤器表面的侧向洗涤。 然后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。
