Abstract: A gross pollutant trap (50) to be installed in a storm water channel so as to receive storm water flowing through the channel and to filer gross pollutants from the storm water. The trap (50) includes a gross pollutant collection area (61) toward which there extends generally parallel sets (63) and (67) of vanes (64) and (68). The area (61) is at least partly defined by a mesh wall (72) through which water returns to the storm water channel.
Abstract: A growth pollutant trap (50) to be installed in a storm water channel so as to receive storm water flowing through the channel and to filter growth pollutants from the storm water. The trap (50) includes a growth pollutant collection area (61) toward which there extends generally parallel sets (63) and (67) of veins (64) and (68). The area (61) is at least partly defined by a mesh wall (72) through which water returns to the storm water channel.
Abstract: A filter apparatus (10) having an upstream first filter grate (17) to which stormwater is delivered so that litter is filtered therefrom. Litter is delivered to a first litter collection surface (20). Extending upwardly from the surface (20) is a filter wall (22) having a filter portion (31) through which the stormwater again passes to filter litter therefrom. A second filter grate (24) extends from an upper portion of the wall (22), the second grate (24) leading to a second litter collection surface (26).
Abstract: A filtering apparatus (1) to filter solid litter from stormwater. The apparatus (1) comprises an inclined filter grate (2) which is located above an outlet (4). The grate (2) extends downwardly from the inlet (3) so that litter is filtered from the stream by the grate 2, with the litter being directed towards a catchment surface (8).
