Abstract: A system to treat effluent in a septic tank includes filter sections having kerfs. A strainer removes solid debris from the filter for removal without allowing the solid debris to pass. An aerator includes an eight to twelve inch diameter pipe 4 to 6 feet tall matching tank invert height. The aerator has bottom inlet holes, each with an elbow on the outside with a vertical standpipe taking effluent from the clear zone, sending it through the aerator. Air inlet piping is attached to a âTâ shaped air diffuser producing bubbles traveling upward through plastic media. Aerator height is field adjusted to approximately 2 inches below static water level. Holes in the upper sidewalls just below the top let air bubbles out sideways. At its top, the aerator has a slotted, sliding, anti-turbulation collar adjusted to be one to two inches above the static water level.
