Abstract: A normal flow filtration system having a housing with one or more filters contained within a bowl and attached to the outlet of the system. Liquid enters the bowl, contacts the surfaces of the one or more filters. Impurities are trapped in the filter and the filtered liquid flows through to the outlet. Parameter(s) such as flow rate, transmembrane pressure drop and/or time are measured and when met, filtration ceases. A backflushing occurs through the filter(s) so as to remove the impurities from the filter. 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 filter(s) can be used to provide a lateral washing of the filter(s). The system is then recirculated in a downstream manner to reestablish equilibrium and filtration is then restarted.

Abstract translation: 一种通常的流动过滤系统，具有一个壳体，一个或多个过滤器包含在一个碗内，并连接到系统的出口。 液体进入碗中，接触一个或多个过滤器的表面。 杂质被捕获在过滤器中，并且过滤的液体流过出口。 测量流量，跨膜压降和/或时间等参数，当满足时，过滤停止。 通过过滤器发生反吹，以从过滤器中除去杂质。 该反冲洗的材料被引导到连接到排水管的碗的出口。 另外，形成在壳体的与过滤器的外表面相邻的侧面中的端口可以用于提供过滤器的侧向洗涤。 然后系统以下游方式再循环以重新建立平衡，然后重新开始过滤。
