Abstract:
1. An aerobic digester for organic material comprising: a vessel for containing a liquid comprising the organic material, the vessel having an interior comprising an upper portion, a lower portion and a lower interior surface; a tube having a distal end disposed in the lower portion of the interior of the vessel, an opening in a wall of the tube for permitting liquid and air flow between an exterior and an interior of the tube, and at least one discharge port disposed in the distal end; and a liquid conveyor connected in fluid communication with the interior of the tube for inducing flow of the liquid along the tube in the direction of the distal end, whereby the liquid conveyor induces entrainment of air drawn into the tube through the opening into the liquid drawn into the tube through the opening to form a liquid-air mixture and expulsion of the liquid-air mixture from the tube through the at least one discharge port into the lower portion of the vessel, thereby causing liquid contained in the vessel to be mixed and aerated.
