ABSTRACT:
A grit chamber for removing grit and other dense inorganic materials from a waste water stream in a waste water treatment facility. The grit chamber includes an upper settling chamber and a lower grit collection chamber, separated by a divider with one or more holes therethrough near the center portion to allow grit to pass. The settling chamber is substantially cylindrical, but with a transition curve connecting the inlet to the cylindrical portion, to assist in the production of a forced vortex with a minimum of turbulence.
