  • Patent number: 11000791
    Abstract: A rotary disc filter includes one or more filter discs secured to a rotary drum and include a series of circumferentially spaced backwash guides disposed in the filter disc. During backwashing, the backwash guides function to engage a mixture of backwash and suspended solids and guide or direct the mixture to a sludge trough disposed in the disc filter. The backwash guides generally assure that a greater percentage of the backwash and suspended solids mixture end up in the solids trough.

  • Patent number: 10729994
    Abstract: A disc filter includes a filtrate holding tank disposed below a series of disc-shaped filter members supported on a drum. Filtrate from the holding tank is used to backwash filter media on the disc-shaped filter members. Filtrate is discharged from the holding tank via a filtrate conduit. Bypass water is directed through a bypass conduit in the disc filter and mixed with the filtrate downstream of the filtrate holding tank. This assures that the filtrate used to backwash the filter media does not include bypass water.
