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.
