A filter assembly is provided. The filter assembly includes a filter cartridge with a containment bag including a vent port and a support housing, including a split lid.

A wastewater filter cartridge includes a peripheral frame, two filter media sheets, two sets of angled fins, and a filtered water outlet. The two filter media sheets are attached to the peripheral frame in spaced face-to-face relation such that they combine with the peripheral frame to define an interior volume within the filter cartridge. At the same time, the two sets of angled fins are attached to the peripheral frame external to the interior volume and project away from the filter media sheets at oblique angles. As wastewater passes through the two filter media sheets into the interior of the filter cartridge, the two filter media sheets act to reduce the suspended solids in the wastewater. Once in the interior volume of the filter cartridge, the filtered water is collected via the filtered water outlet, which is connected to the interior volume.

The present invention relates to a backwashing device for a fibrous filtration apparatus, and the fibrous filtration apparatus including the same, in which a portion of an inner space formed by a suction body and a suction plate in which backwashing is performed is divided, and water or a cleaning agent is supplied to the divided space from the outside and is evenly ejected and applied to a surface of a disk-type filter medium, so that materials, which are not easily removed by water, such as foreign substances and grease attached and fixed to a fiber part of the disk-type filter medium are cleanly removed, and thus backwashing efficiency can be improved.
