Abstract: A water filter arrangement (10) for trapping gross pollutants flowing in a storm water system is provided in-line or at end-of-line of a storm water pipe. The arrangement comprises an inlet (14) and an inlet area (18) which directs incoming water (16) into a filter (20). The filter traps entrained gross pollutants and filtered water exits the filter via filter outlet (50). The outlet (50) and surrounding walls (58 and 57) are shaped to create a flow of filtered water which forms a water barrier which restrains the flow of water and gross pollutants from the inlet (14) to the outlet (52). The water barrier is located between the inlet (14) and the outlet (52) preferably closer to the outlet than the inlet. As the filter (20) becomes full and the flow of filtered water exiting the filter decreases the water barrier subsides. When the filter is completely blocked, the water barrier completely subsides and the incoming water and gross pollutants by-pass the filter (20) and flow unrestrained without head loss from the inlet (14) to the outlet (52).

Abstract translation: 在雨水管道的直线或行尾设置有用于捕获在雨水系统中流动的总污染物的滤水器装置（10）。 该装置包括入口（14）和将进入的水（16）引导到过滤器（20）中的入口区域（18）。 过滤器夹带的总污染物和过滤水通过过滤器出口（50）离开过滤器。 出口（50）和周围壁（58和57）被成形为产生过滤水流，其形成水屏障，其限制水和从污染物入口（14）到出口（52）的总污染物质。 水阻挡物位于入口（14）和出口（52）之间，优选地比入口更靠近出口。 当过滤器（20）变满时，离开过滤器的过滤水的流量减少，阻水减少。 当过滤器被完全堵塞时，防水层完全消失，进水和总污染物绕过滤器（20）并且流过无限流而不会从进口（14）到出口（52）的头部损失。
