Claim:
A processing system for treating wastewater, comprising: (a) a wastewater treatment container having a top, a bottom, and a height dimension therebetween and adapted to receive wastewater from a wastewater stream; (b) a mixing/aeration system disposed in the wastewater treatment container at a position therein so as to mix and/or aerate wastewater in the wastewater treatment container and including an inlet for receiving retentate wastewater and an outlet for ejecting retentate wastewater into the wastewater treatment container; (c) a solids/liquid separation system having an inlet for receiving treated wastewater and a retentate wastewater outlet; and (d) a pumping system coupled so as to create a pressure differential across the mixing/aeration system and the solids/liquid separation system to move treated wastewater from the wastewater treatment container to the inlet of the solids/liquid separation system and retentate wastewater from the outlet of the solids/liquid separation system to the inlet of the mixing/aeration system and out of the outlet of the mixing/aeration system into the wastewater treatment container.
