1. An apparatus for converting a standard anaerobic septic tank system into a highly efficient aerobic wastewater treatment system comprising:

  • a new septic tank lid having an upper side and an underside sized to conform to the configuration of the septic tank system;

    aeration means including aid supply conduit lines and flow control means for conveying air to a pair of spaced air diffuser assemblies located near the bottom of said septic tank;

    said aeration means including said air diffuser assemblies attached to said underside of said new septic tank lid;

    a clarifier insert and adjustment means for adjustably attaching said clarifier insert to said underside of said new lid and centrally positioning said clarifier insert between said air diffuser assemblies within said old septic tank;

    said clarifier insert having an upper and lower opening with a vertical wall extending therebetween forming a quiescent zone therein;

    an effluent discharge assembly operably positioned in said clarifier insert with said discharge conduit extending through said wall of said clarifier insert and connected to the septic tank system discharge outlet;

    whereby insertion of the aforementioned components into said septic tank converts said anaerobic tank to a highly efficient aerobic system when said air supply conduit lines provide air to said air diffuser assemblies and generates a generally vertical flow regime in said septic tank on opposite sides of said clarifier insert thus producing aeration and aerobic biochemical breakdown of the solids during mixing of the solids and liquids within said septic tank and allowing mixed liquor to enter said lower opening in said clarifier insert whereby solids in the quiescent zone within said clarifier insert fall by gravity through said lower opening into said septic tank for further mixing and solid-free liquid enters said inlet of said effluent discharge conduit and exits said septic tank.
