Benefits of technology

[0008]It is another object to provide a method which removes organic materials and nutrients from the septic tank effluent, and purifies the effluent to such an extent that it can safely be discharged to the environment.

Problems solved by technology

The rate at which liquid effluent is pumped to the bottom of the treatment vessel is sufficiently low that the treated effluent which reaches the top of the treatment vessel is substantially devoid of organic materials and nutrients.

Embodiment Construction

[0056]The instant invention, in one aspect, is a method for treating the liquid effluent from a septic tank and apparatus which is useful for practicing the method. Referring to FIG. 1, the liquid effluent from a septic tank 10 is collected in a holding tank 11, from which it is pumped from time to time by a pump 12 to a receiver 13 in the bottom of a treatment vessel 14 that is packed with pebbles, glass fibers and sand. The pump 12 mixes air with the effluent it pumps to the receiver 13, which has a pervious top, so that air and effluent flow from the receiver 13 into the bottom of the vessel 14, which the effluent eventually fills to a predetermined level while the effluent in the vessel is aereated by the air. Thereafter, additional effluent causes a non-turbulent, upward movement thereof in the vessel 14 while air delivered with the effluent continues the aeration. Effluent delivered by the pump 12, when it reaches the top of the vessel 14, contacts and is heated by a heater 15...

Abstract

A method for producing a foundation for a building is disclosed. The method comprises digging a trench having the shape and position required by the foundation for the building, pouring a hardenable concrete footer in the trench, assembling a slab jig on the footer, positioning the slab jig, if necessary, so that the upper surface of a concrete slab which subsequently fills the slab jig is substantially level, and filling the slab jig with a hardenable concrete. The slab is one having an open top, an open bottom, and sidewalls so shaped that the upper surface of a concrete slab which fills the slab jig is substantially flat and the slab has the shape required of the foundation for a particular building, In a preferred method, also disclosed, a course of cement blocks is laid on the footer, and the slab jig is assembled on the cement block course, positioned, if necessary, and filled.

Description

REFERENCE TO RELATED APPLICATION[0001]This is a continuation in part of application Ser. No. 11 / 592,013, filed Nov. 2, 2006FIELD OF THE INVENTION[0002]This invention is a method for treating septic tank effluent and, more particularly, is such a method in which the effluent is treated to eliminate organic materials and nutrients therefrom before it is discharged to the environment. Preferably, the treated effluent is pasteurized, and the pasteurized material is then discharged to the environment as either a liquid or a vapor which, in either case, is not a health hazard. The invention is also a structure in which the method described above can be practiced, and a house which can contain that structureBACKGROUND OF THE INVENTION[0003]On site sewage disposal systems are frequently used in rural and other areas where municipal plants are not available. Typically, waste processed in such a system enters a septic tank in which solids settle to the bottom and grease and scum float to the ...
