Air is injected into an eductor tube located in the center of the basin, creating a vertical pumping action that circulates the tank’s contents. This circulation keeps organics in suspension while allowing the heavier grit to settle at the bottom of the Aeroductor where it is scoured, washed and collected in a central hopper.
An energy recovery baffle above the eductor, at the water level, increases efficiency by directing the vertical flow horizontally across the tank surface to the walls and then downward in a circulating flow pattern. Aeroductor circulation velocities are easily controlled by simple adjustments of the air supply valve.
An air lift pump, centrally located in the eductor tube, draws grit from the bottom of the Aeroductor to the air lift inlet. The mixture of air, liquid and grit is lifted to the head box where the air is vented while the liquid/grit mixture is directed to the Grit Classifier, separating and dewatering grit. If settled grit is allowed to build up, a handwheel-operated retractable foot piece can be elevated to clear the inlet, then lowered slowly as the pumping action continues to remove accumulated grit.
