<p>Apparatus and method for circulating, treating and separating a mixture of wastewater and solids. The apparatus includes a tank housing (40), an inverted funnel-like element (16) for constricting upward flow of a gasborne mixture, and a containment element (12) between the funnel and an effluent weir (44). For aerobic treatment, a diffuser (20) is arranged within the funnel to supply air and create the upward flow. For anaerobic treatment, the tank is atop a digestor containing a sludge blanket and anaerobic bacteria producing biogas.</p> |
