摘要： A wastewater filter includes a vessel having a bottom and a side wall that cooperate to define a filter space. A first filter media is positioned within the filter space to define a first media layer, and a second filter media different from the first filter media is positioned within the filter space above the first media layer to define a second media layer, the first media layer and the second media layer cooperating to define an interface plane. A draft tube is positioned within the second media layer and has a first end positioned a first non-zero distance above the interface plane, and a second end disposed a second non-zero distance from a top surface of the second media layer. A backwash fluid line is positioned to inject a backwash fluid into the first filter media, and a backwash gas line is positioned to inject a backwash gas into the draft tube.

摘要： The present invention relates to a filtering apparatus (1) for the filtration of liquids, in particular water. It comprises, inside a container (11), a first chamber (50) intended to receive liquid to be filtered, a second chamber (54) intended to receive filtered liquid, a first porous wall (51) and a second porous wall (53) which delimit a filtration chamber (40) between them. The first porous wall (51) divides the first chamber (50) from the filtration chamber (40) and the second porous wall (53) divides the second chamber (54) from the filtration chamber (40), so that the filtration chamber (40) is interposed between the first chamber (50) and the second chamber (54). A granular filter material (4) is housed in the filtration chamber (40) and is enclosed between the first porous wall (51) and the second porous wall (53). The first chamber (50) receives the liquid to be filtered at a first height (HI) which is at a higher altitude than the second height (H2) at which the second chamber (54) discharges the filtered liquid. The first chamber (50), the filtration chamber (40) and the second chamber (54) are flanked to each other and, in a section between the first height (H1) and the second height (H2), are all intersected by a plurality of horizontal planes (P) parallel to each other. In use, the liquid to be filtered passes from the first chamber (50) to the second chamber (54) substantially by gravity and through the filtration chamber (40) with a flow path having a horizontal component.
