A sub-soil wastewater treatment vessel, especially for wastewater produced by single family residences and small businesses and the like. The vessel is divided into at least three contiguous chambers by at least two transverse walls, forming at least two contiguous aeration chambers and a clarifier chamber. Wastewater flows into the first aeration chamber via an influent line, thence through an opening in the first transverse wall into the second aeration chamber. From there, wastewater flows through passages at the bottom of the second transverse wall into the clarifier chamber. Air is supplied to the first and second aeration chambers via low pressure diffuser lines. Three inclined surfaces within the clarifier chamber direct solids through passages in the second transverse wall back into the second aeration chamber for further processing. An effluent line connected to the clarifier chamber permits wastewater outflow.

Sub-soil domestic wastewater treatment apparatus having multiple aeration chambers

A sub-soil apparatus for treatment of domestic wastewater and sewage, such as that generated from single family residences, small apartment buildings, small offices and the like. The apparatus includes two contiguous chambers, the first chamber being a mixing/aeration chamber, and the second being a settling/separation chamber. A transverse wall with lower lateral passages divides the two chambers but allows liquid and solid exchange between the two chambers. The mixing/aeration chamber accepts the sewage to be treated, and turbulent mixing and aeration is achieved therein by a transverse aeration bar. After mixing and aeration, which results in biodegradation of the sewage, the biodegraded liquid, containing fine solids, passes into the settling/separation chamber where quiescent conditions promote solid settling. Three inclined walls of the settling/separation chamber direct settled solids back into the mixing/aeration chamber for further biodegradation. A multiple angle discharge fitting also discourages solids from entering the effluent line.
