Abstract
Abstract Domestic waste water is treated by aerobic action in a plurality of tank sections, moving from one to another as successive steps of treatment. In the first section the influent is received and air agitation is provided to supply oxygen and to break up large particles. The water flows to several successive sections from some of which it is both continuously recycled and also periodically recycled to the first section to complete as much of the treatment there as possible. In one section an elongated settling compartment is provided to settle out the inert small particles. The discharge is by displacement from the final section. The system also preferably has a positive displacement airlift transfer from at least one section to the next as the only means of communication between these sections to provide flow only when the treatment system is being supplied with air, and the system will back-up when the supply is removed thus requiring the user to provide the necessary repair to restore the proper functioning of the system.

Claim 3
Dependent Claim
43 words
The invention as defined in claim 1 wherein said return means includes air lift means to continuously return a portion of the waste water from the surface of the intermediate section directly connected to the influent receiving section to said influent receiving section.
Claim 4
Dependent Claim
34 words
The invention as defined in claim 1 wherein said return means includes air lift means and timing means there for to periodically return the waste water at regular periodic intervals for a predetermined time.
Claim 5
Dependent Claim
43 words
The invention as defined in claim 1 wherein there are at least two intermediate sections, and wherein said return means includes air lift means to continuously return waste water to said influent receiving section from the surface of the intermediate section connected thereto.
Claim 6
Independent Claim
212 words
A method of treating residential waste water comprising the steps of, providing a plurality of separate tank sections, including an influent receiving section, an effluent discharge section, and at least one intermediate section, delivering influent to said influent receiving section, air agitating the material in the influent receiving section, providing fluid flow from said influent receiving section to an intermediate section responsive and proportional to influent flow to the influent receiving section, at least periodically returning a portion of the material to the influent receiving section from the intermediate section connected thereto, delivering material from the intermediate section to the discharge section responsive and proportional to the material delivered to the intermediate section, and discharging effluent from the effluent discharging section above a given level therein responsive and proportional to the material therein received, further characterized by the flow from one section to the next succeeding section being a positive delivery of waste water above a given level and responsive and proportional to the material received therein as the only fluid connection therebetween and operative by the means providing air agitation whereby the flow through and out the discharge is proportional to the intake as long as air is provided but flow through is halted when the air means ceases to function.
