摘要： A stormwater pollution separator and filter apparatus to be fitted inline in a stormwater conduit. The apparatus has an inlet (1) receiving stormwater and leading through an inlet aperture (3) to a separation chamber (4) which then leads to a filtration chamber (5) which is positioned below the inlet aperture (3). A riser (6) leads from the filtration chamber (5) to an outlet (7) which is connected back to the stormwater conduit (3). The inlet opening is connected tangentially into the separation chamber (4) to create, in use, a swirl action in the separation chamber (4) by reason of the flow of the stormwater. The separation chamber (4) is positioned vertically above the filtration chamber (5), and the filtration chamber (5) has one or more filtration baskets (9) positioned in the filtration chamber (5) to receive substantially all the flow of stormwater from the separation chamber (4), the baskets (9) are spaced apart from a wall (10) defining a periphery of the filtration chamber (5). An overflow communicates directly between the inlet and the outlet, and a weir (14) is positioned in the overflow to prevent flow through the overflow unless a predetermined level of stormwater is exceeded.

摘要： The gross pollution trap comprises an upper inlet portion directing stormwater through a filter inlet aperture to a filter chamber defining a filter flow path. The filter chamber is positioned in a lower portion of the trap. A filter is positioned in the filter flow path to collect debris from water flowing through the flow path. An outlet leads from the lower portion of the trap and in use is connected with a stormwater egress pipe. An overflow weir is locate in the upper portion of the trap is spaced above the filter inlet aperture, an water flowing over the weir spill into an overflow path ending at the outlet. The weir preferably has a return extending upstream from an upper portion of the overflow weir.
