Abstract:
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.

Claim (Index 11):
A grit removal unit for a wastewater system, comprising:\n a round grit removal chamber defined by a bottom surface and a vertical wall substantially annular about a center and extending up from said bottom surface, said chamber vertical wall having a radius of R VW  around a chamber center; a substantially horizontal annular ring extending inwardly a radial distance R d  from the chamber vertical wall, said ring being above said chamber bottom surface and extending around the entirety of the chamber annular vertical wall; an influent channel through an opening in said chamber vertical wall and beneath said ring, said influent channel having\n a first influent side wall substantially tangential to said chamber vertical wall at said influent channel opening in said chamber vertical wall, \n a second influent side wall substantially parallel to said one influent side wall and spaced from said one influent side wall by said distance R d , and \n a curved extension of said second influent side wall within said chamber, said curved extension having a radius of R ex , wherein R ex =R VW \u2212R d , and \n said second influent side wall and curved extension extend from said chamber bottom surface to said ring wherein said influent channel is defined between said first and second influent side walls, said curved extension, said ring, and said chamber bottom surface; and \n an effluent opening through said chamber vertical wall and above said ring, wherein said influent channel has an outlet at the end of said inner side wall and located sufficiently around said removal chamber to substantially prevent influent from said influent channel outlet exiting to said effluent channel input without first entirely circling said chamber; wherein said curved extension of said influent channel second side wall extends through an arc of at least about 90 degrees around said center.
