  • Patent number: 10016706
    Abstract: A fluid filtering apparatus such as for filtering particulates and other materials from treated water includes a tank and a filtering region configured as a plurality of individual effluent regions, defined in part by channel frames, disposed between a plurality of influent regions interposed between the effluent regions. Filter plates having an opening therethrough covered by a filter media are removable receivable in the channel frames, such that filter media in filter plates in adjacent channel frames is in a facing, opposed, relationship. A double sided backwash shoe is scannable in the influent regions, to simultaneously clean opposed filter media exposed thereto. The backwash shoe is free to move inwardly and outwardly of the opposed filter media. Additionally, the tank may include a second filtering region, which is selectively isolatable from the first filtering region.

A double sided backwash shoe is scannable in the influent regions, to simultaneously clean opposed filter media exposed thereto. The backwash shoe is free to move inwardly and outwardly of the opposed filter media. Additionally, the backwash shoe includes an end opening, positioned adjacent to the base of the tank, to remove sludge and particulates which have settled to the area near the base of the tank while backwashing a filter media.
