Patent number: 10309090Abstract: A grit removal unit for a wastewater system including a grit removal chamber with a substantially annular vertical wall. A horizontal annular ring above the chamber bottom extends inwardly from the annular vertical wall, with an influent channel extending into the chamber beneath the ring and an effluent channel above the rim and extending out of the chamber. The influent and effluent channels both have inner side walls with a curved portion, with both curved portions extending through an arc of at least 90 degrees within the chamber annular vertical wall.Type: GrantFiled: January 31, 2018Date of Patent: June 4, 2019Assignee: Smith & Loveless Inc.Inventors: Francis M. Noonan, Dale White, Rodney S. Mrkvicka

Patent number: 9662666Abstract: A grit removal unit including an influent channel directing wastewater with grit into a round grit removal chamber and an effluent channel receives wastewater output from the chamber. A divider wall extends upwardly between the sides of the influent channel, and gates at the upstream end of the divider wall are adjustable to selectively open channel portions on opposite sides of the divider wall. An output guide member is mounted to allow selective adjustment of output flow opening width “c” to the effluent channel. The output guide member has a horizontal bottom extending from the chamber into the effluent channel across the width of the output opening, and a guide wall extending upwardly from the guide member bottom. The guide wall has a forward end spaced from the chamber annular vertical wall to define the output flow opening width therebetween.Type: GrantFiled: May 9, 2016Date of Patent: May 30, 2017Assignee: Smith & Loveless, Inc.Inventors: Francis M. Noonan, Frederick Trentadue, John K. Kelly, Dale White, Rodney S. Mrkvicka

Patent number: 8906233Abstract: 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.Type: GrantFiled: April 16, 2012Date of Patent: December 9, 2014Assignee: Smith & Loveless, Inc.Inventors: Harrison J. Messick, Frank G. Weis, Francis M. Noonan
