Abstract
Abstract Sewage treatment device comprises an enclosed housing having exterior walls and first and second interior walls forming first, second and third compartments within the housing. A first opening is provided in the first interior wall forming communication between the first and second compartments, and a second opening is provided in the second interior wall for providing communication between the second and third compartments. The openings are placed at a predetermined height so that the fluid will rise to the predetermined height and then overflow into the next adjacent compartment. A recirculating pump is located in the third compartment and recirculates fluid back into the second compartment where it is sprayed into the second compartment by means of spray heads, one of which is located above the fluid level and one of which is located below the fluid level. Vent means are provided in the housing for providing communication between the second compartment and the atmosphere so that oxygen is exposed to the fluid in the second compartment. A field pump within the third compartment pumps the fluid therein out of the third compartment to the exterior of the housing whenever fluid rises above the predetermined height within the third compartment.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
310 words
A sewage treatment device comprising: an enclosed housing having opposite end walls, opposite side walls, a top wall and a bottom wall; first and second upstanding partition walls each engaging said bottom wall and opposite side walls of said housing so as to divide said housing into first, second, and third serially connected compartments; said first partition wall having a first opening located at a first predetermined height above said bottom wall and forming communication between said first and second compartments; said second partition wall having a second opening located at a second predetermined height above said bottom wall and forming communication between said second and third compartments; an inlet conduit forming communication from the exterior of said housing to the interior of said first compartment; vent means in said top wall of said housing forming communication between said second compartment and the atmosphere whereby gases produced by sewage decomposition may escape and oxygen may enter said second compartment; a recirculating pump having an inlet adjacent the bottom of said third compartment; a recirculating conduit connected to said recirculating pump and extending into said second compartment adjacent said first partition wall; upper and lower spray heads connected to said recirculating conduit adjacent said first partition wall, said upper spray head being positioned above said second predetermined height so as to spray effluent into the vented space within said second compartment above the fluid level therein, said lower spray head being positioned adjacent said bottom wall of said second compartment and adjacent said first partition whereby effluent exiting from said upper and lower spray heads will impart a circular agitation to said fluid in said second compartment and a field pump within said third compartment for pumping fluid out of said third compartment to the exterior of said housing whenever fluid rises above a third predetermined level within said third compartment.
Claim 2
Dependent Claim
310 words
A sewage treatment device comprising: an enclosed housing having opposite end walls, opposite side walls, a top wall and a bottom wall; first and second upstanding partition walls each engaging said bottom wall and opposite side walls of said housing so as to divide said housing into first, second, and third serially connected compartments; said first partition wall having a first opening located at a first predetermined height above said bottom wall and forming communication between said first and second compartments; said second partition wall having a second opening located at a second predetermined height above said bottom wall and forming communication between said second and third compartments; an inlet conduit forming communication from the exterior of said housing to the interior of said first compartment; vent means in said top wall of said housing forming communication between said second compartment and the atmosphere whereby gases produced by sewage decomposition may escape and oxygen may enter said second compartment; a recirculating pump having an inlet adjacent the bottom of said third compartment; a recirculating conduit connected to said recirculating pump and extending into said second compartment adjacent said first partition wall; upper and lower spray heads connected to said recirculating conduit adjacent said first partition wall, said upper spray head being positioned above said second predetermined height so as to spray effluent into the vented space within said second compartment above the fluid level therein, said lower spray head being positioned adjacent said bottom wall of said second compartment and adjacent said first partition whereby effluent exiting from said upper and lower spray heads will impart a circular agitation to said fluid in said second compartment and a field pump within said third compartment for pumping fluid out of said third compartment to the exterior of said housing whenever fluid rises above a third predetermined level within said third compartment.
Claim 3
Dependent Claim
70 words
A sewage treatment device according to claim 1 comprising first and second baffle walls within said first compartment extending from said first interior wall of said housing in planes perpendicular thereto; said first and second walls forming in cross-section the legs of a y-shaped configuration with said legs being spaced apart at the juncture therof, said scoop and opening being positioned between said baffle walls above said y-shaped juncture thereof.
Claim 4
Dependent Claim
35 words
A sewage treatment device according to claim 1 wherein said upper spray head is positioned to spray in a downwardly inclined direction and said lower spray head is positioned to spray in an upward direction.
Claim 5
Dependent Claim
97 words
A sewage treatment device according to claim 1 comprising baffle means within said second compartment positioned in spaced relationship to and between said spray heads and said second opening; said baffle means having opposite side edges in engagement with said opposite side walls of said housing, said baffle means extending downwardly from above said second predetermined height and terminating in a lower edge spaced from and adjacent said bottom wall of said housing whereby effluent must pass below said lower edge of said baffle means in order to move from said spray heads to said second opening.
Claim 6
Dependent Claim
57 words
A sewage treatment device according to claim 4 wherein said upper spray head is positioned to spray in a downwardly inclined direction and said lower spray head is positioned to spray in an upward direction, said baffle means having an approximately arcuate surface oriented approximately tangential to the circular movement of said fluid within said second compartment.
Claim 7
Dependent Claim
42 words
A sewage treatment device according to claim 5 wherein said second partition comprises an arcuate portion adjacent the lower end thereof to provide a concave curved surface at the juncture between said second partition and said bottom wall within said second compartment.
