DISK TYPE FILTERING APPARATUS

摘要

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.

1. A fluid filtering apparatus, comprising:
a containment volume having a fluid influent inlet and a fluid effluent outlets; a filtration region disposed intermediate of the fluid influent inlet and the fluid effluent outlet, the filtration region including a plurality of effluent volumes, each effluent volume extending from a location adjacent the fluid effluent outlet, and in fluid communication with the fluid effluent outlet, the filtration region further including a plurality of influent volumes extending from a location adjacent the fluid influent inlet, and in fluid communication with the fluid influent inlet, wherein each influent volume is disposed between two adjacent effluent volumes; a filter media disposed between the influent volumes and the effluent volumes for fluid communication of fluid through the filter media and for trapping of particulates disposed in an influent fluid as the influent fluid passes through the filter media from the influent volumes to the effluent volumes; and a travelling backwash unit having at least a first backwash shoe extending vertically into a first of said plurality of influent volumes and moveable across a surface of the filter media in the first influent volume.
