Abstract
A gas baffle for a waste water treatment plant filter housing that includes a first and second deflecting plate. The gas baffle has at least one flow-through opening defined by the first and second deflecting plates. The combination of the first and second deflecting plates deflects rising gas bubbles and any solid particulates so that the bubbles and particulates do not enter the filter housing. The gas baffle may include exterior apertures to dissipate the rising gas bubbles that travel on the bottom surface of each deflecting plate. The gas baffle may be integrally formed with the filter housing or created separately and subsequently connected.
Claims20
A filter cartridge for use in a filter housing comprising:
- a filter cartridge having a plurality of stacked vertical filter plates, said plurality of vertical filter plates includes a front plate, a middle plate, and a back plate;
- said front plate having a plurality of substantially lateral projections, whereby said plurality of lateral projections are vertically spaced from each other and abut said adjacent middle plate creating separate filtering tiers between said adjacent front and middle plates;
- said back plate having a plurality of substantially lateral projections, whereby said plurality of lateral projections are vertically spaced from each other and abut said adjacent middle plate creating separate filtering tiers between said adjacent back and middle plates;
- said front plate having a plurality of filtering apertures, said plurality of filtering apertures positioned along said vertically extending front plate;
- said middle plate having a plurality of filtering apertures, said plurality of filtering apertures positioned along said vertically extending middle plate;
- and
- said back plate having a plurality of filtering apertures, said plurality of filtering apertures positioned along said vertically extending back plate.
A stacked filter cartridge and filter outlet tee comprising:
- a filter outlet tee with an outlet opening and an inlet bottom opening, said outlet opening in fluid communication with said inlet bottom opening, said filter outlet tee receiving a filter cartridge;
- said filter cartridge including a plurality of stacked plates, said plurality of stacked plates includes a substantially vertical front plate, a substantially vertical middle plate, and a substantially vertical back plate;
- at least one pair of lateral projections extending between adjacent said front and middle plates, said pair of lateral projections include a top lateral projection and a bottom lateral projection, wherein said top lateral projection is vertically spaced from said bottom lateral projection and defines a first flow-through tier;
- at least one pair of lateral projections extending between adjacent said middle and back plates, said pair of lateral projections include a top lateral projection and a bottom lateral projection, wherein said top lateral projection is vertically spaced from said bottom lateral projection and defines a second flow-through tier;
- one or more filtering apertures positioned along each one of said vertically extending plurality of stacked plates;
- and
- wherein said first flow-through tier is vertically offset from and in fluid communication with said second flow-through tier.
A filter cartridge comprising:
- a filter cartridge including a plurality of stacked plates, said plurality of stacked plates includes a substantially vertical front plate, a substantially vertical middle plate, and a substantially vertical back plate;
- a first plurality of lateral projections transversely extending between adjacent said vertical front and middle plates creating a first plurality of front angled tiers between said front and middle plates;
- a second plurality of lateral projections transversely extending between adjacent said vertical middle and back plates creating a second plurality of rear angled tiers between said middle and back plates;
- said first plurality of front angled tiers vertically offset from said second plurality of rear angled tiers;
- and
- one or more filtering apertures positioned along each one of said vertically extending plurality of stacked plates.
