Abstract

Apparatus for separating grit from a grit-loaded liquid matrix while retaining organic solids in suspension, including an inlet for admitting liquid matrix into the apparatus, an outlet for removing grit-lite liquid matrix from the apparatus main chamber, and a vortex system for removing separated liquid matrix grit from the apparatus. The grit settling main chamber defines upper and lower subchambers communicating with each other through a central aperture. A fluid flow speed gradient is established between the apparatus fluid inlet and outlet. An Eddy type fluid dynamic component is added, providing combined enhanced coarse grit and fine organics discrimination and separation. The Eddy fluid dynamic component may consist of a trio of stationary fresh water supply force fed eductors. Each eductor produces a fresh water fluid flow interacting with the liquid matrix fluid flow inside the upper subchamber, whereby Eddy-type turbulences are generating promoting fine, liquid matrix grit particle separation from the liquid matrix.
