Abstract
An apparatus provides for treatment of primary effluent from residential and commercial establishments to allow subsurface or surface disposable of wastewater. A single tank includes dosing and recirculation chambers 28, 30 having no direct fluid communication therebetween and divided by a vertical chamber wall 32. A filter layer 26 is positioned atop both chambers such that wastewater that is filtered therein then flows into both the dosing and recirculation chambers. The position of the wall 32 determines the proportion of filtered wastewater that flows into each chamber by gravity.
Claims25
A wastewater treatment apparatus comprising:
- a recirculation chamber;
- a dosing chamber having no direct fluid connection to the recirculation chamber, and separated therefrom by a substantially vertical chamber wall;
- a filter layer containing a filter media and being located atop the recirculation and dosing chambers and the substantially vertical chamber wall, the recirculation chamber, the dosing chamber, and the filter layer being located in a single tank;
- an influent pipe that directs wastewater entering the wastewater treatment apparatus into the recirculation chamber;
- a recirculation pump located in the recirculation chamber, the recirculation pump pumping the wastewater from the recirculation chamber onto the filter layer;
- a porous filter underdrain, the wastewater treatment apparatus being configured such that the wastewater flowing through the filter media of the filter layer is directed through the underdrain and is then directed simultaneously into the recirculation chamber and the dosing chamber by gravity;
- a septic tank return pipe connected to the dosing chamber, a portion of the wastewater being discharged from the wastewater treatment apparatus through the septic tank return pipe back to a septic tank for additional treatment;
- and
- an effluent discharge pipe connected to the dosing chamber, the wastewater being discharged from the wastewater treatment apparatus through the effluent discharge pipe for final disposal.
