Wastewater treatment system for residential septic systems

DETAILED DESCRIPTION A supply tank or canister of liquid containing an aqueous solution of chlorine hereafter referred to as "chlorine canister" located in or near the storage-mixing tank and a chlorine solution supply tubing hereafter referred to as "chlorine supply tubing" (shown as a ¼"; line) is connected from the chlorine canister to a venturi chamber.
The chlorine supply tubing within the canister is provided with a filter/orifice assembly having an orifice dimension that is designed for the size of the wastewater treatment system.
It should be borne in mind that the term "canister" is used to mean a container or vessel of any suitable size, which contains a volume of chlorine, either in liquid solution or gaseous form, and which can be serviced or refilled when the supply of chlorine becomes low.
As will become apparent, the canister may be located adjacent to the storage-mixing tank or within the tank as desired.
A pump within the storage-mixing tank, or having its inlet or suction opening in communication with the storage-mixing tank causes circulation of sewage effluent, also referred to herein as wastewater, through a venturi chamber (also designed according to the size of the treatment system).
The flow of wastewater through the venturi (restrictor disc) develops a significant drop in pressure in the venturi chamber, which is less than atmospheric pressure, allowing the atmospheric pressure to push chlorine solution from the storage canister, through the filter and orifice assembly, the supply tubing, and into the flowing treated effluent stream.
The layman term for this phenomenon is referred to as "suction.
" A ½";-1"; recirculation pipe section extends from the venturi chamber into the storage-mixing tank, and has a terminal end defining an opening that is oriented to cause turbulence or circulation of wastewater and chlorine within the tank for efficient mixing of liquid and dissolved solid (typically NOT seen by the naked eye) constituents of the sewage effluent
