ABSTRACT:
A method of collecting and transferring settling solids that are being settled from raw surface water or wastewater includes collecting settling solids and applying first and second upward flows to the settling solids. The solids are collected in a chamber having a bottom surface and a surrounding side surface. The first upward flow is applied to the solids from a point adjacent the bottom surface. The second upward flow is a suction flow applied at a point above the first upward flow. The first and second flows urge the settling grit upward and out of the chamber through a passageway.
