    Abstract: A floating media filter including a filter housing with an influent conduit extending into the filter housing, the influent conduit having at least one outflow aperture positioned below an effluent outlet of the filter housing. A floating media is positioned in the filter housing and forms a media bed when the filter is in a filtration stage, the media bed having a lower surface and an upper surface defining a filtration zone between the lower and upper media bed surfaces during the filtration stage. A diffuser trough is positioned in the filter housing such that (i) the lower surface of the media bed, when the filter is in the filtration stage, is below an upper edge of the diffuser trough, and (ii) the outflow aperture of the influent conduit is positioned sufficiently close to a surface of the diffuser trough such that influent flow, during the filtration stage, is initially directed against and/or along the surface of the diffuser trough, and then redirected in a path into the media bed. Finally, the media filter includes a backwashing mechanism causing (i) lowering of the upper surface of the media bed to a point below the upper edge of the diffuser trough, and (ii) creation of an air space in a substantial portion of the filtration zone.

    Abstract: Water filters which comprise a multitude of discrete filter media elements in a chamber require periodic cleaning. However, the elements tend to become adhered to one another and to the interior surface of the chamber. The invention provides a water filter for use with ponds, comprising a filter chamber for containing filter media, and a first movable cutting member provided substantially immediately adjacent the interior wall of the chamber for movement across the surface of the interior surface of the wall to break the adherence of filter media to the interior wall.

    Abstract: A cleansing tank 38 and a screw conveyor 32 are removably mounted to a mounting opening 22 of a filtration tank 2. When the cleansing tank 38 and the screw conveyor 32 are to be removed, they can be extracted to the exterior of the filtration tank 2, by detaching a base 28, which axially supports the screw conveyor 32, from a rim 24. Purified water is backwashed through a purified water discharge pipe 60 when the cleansing tank 38 and the screw conveyor 32 are extracted and inserted through the mounting opening 22. This causes filtration media 14 to float, thereby reducing the resistance thereof.
