ABSTRACT:
A self-contained wastewater treatment system is provided, comprising a vessel having a bottom, side walls and a lid defining a hollow interior for containing wastewater, the vessel being adapted for installation underground; an influent line; an effluent line; and a baffle disposed within the interior, generally between the influent line and the effluent line and extending transversely toward opposing side walls of the vessel. The baffle includes a bottom edge separated by a predetermined distance from the bottom of the vessel to define a flow opening. The position of the baffle defines an upstream aeration chamber and a downstream clarifier chamber within the vessel. The side walls include a downstream end wall, the downstream end wall having a lower inclined wall which intersects the bottom of the vessel adjacent the flow opening. Also included are aeration means for producing aeration within the aeration chamber, positioned to produce a generally circular flow path within the aeration chamber, the circular flow path having a flow path component adjacent the flow opening with a flow direction generally away from the clarifier chamber. The vessel also includes a solids removal device operatively disposed between the aeration chamber and the clarifier chamber for drawing solids in the wastewater within the clarifier chamber and transferring the solids back into the aeration chamber.
