Individual home wastewater treatment plant conversion apparatus
First Claim
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.

Abstract
The disclosure pertains to a method and apparatus for converting a standard anaerobic septic tank system to an aerobic system where the effluent discharged has a high level of quality, sufficient to meet or exceed all known national and state standards. The method provides a series of steps that are used to convert a pre-existing anaerobic septic tank to a highly efficient aerobic system. Additionally, there has been provided an apparatus for individual home wastewater treatment that is designed for new construction units. The conversion and new construction units are highly effective in geographical regions where the native soils have inadequate percolating capacity and also areas in which the groundwater table is very near the surface. Both of these units include an aeration and a clarifier insert with the capability of adding an optional chlorine chamber which dispenses chlorine into the effluent line in its final stages. Although only a single clarifier unit is used in each installation, provision is made for a plurality of clarifier insert configurations, any of which will meet the high quality standards indicated above.
