  • Patent number: 8906233
    Abstract: A grit removal apparatus has a central opening between a cylindrical separation chamber above a grit storage chamber. An influent flume introduces a liquid stream directly into a lower portion of the periphery of the separation chamber, and an effluent flume removes a stream through an opening in an upper portion of the separation chamber wall. Outwardly spiraling vanes extend upwardly at the bottom center of the separation chamber, and a vertical cylindrical duct is supported above the vanes. A tunnel is defined in the separation chamber by an upper wall at the bottom of that opening and an inner wall concentric with the separation chamber wall. A ring extends inwardly from the separation chamber wall, with the tunnel upper wall defining a portion of the ring. A propeller inside the duct rotates to draw fluid flow up through the duct toward the upper portion of the separation chamber.

  • Patent number: 7971732
    Abstract: A grit removal unit for a waste water system, including a round grit removal chamber with an input for waste water and an output, a grit storage chamber beneath the grit removal chamber, and an opening between the grit storage chamber and the grit removal chamber. A vertical drive shaft extends through the grit removal chamber into the grit storage chamber, and is rotatable to facilitate waste water flow in the grit removal chamber whereby grit in the waste water is directed toward the opening. A grit size restrictor includes a shear secured to the drive shaft for rotation therewith (the shear including a plate extending radially from the drive shaft above the opening), a first set of bars extending across the opening, and a second set of bars secured to the bottom of the shear plate with the second set of bars positioned adjacent the first set of bars.
