Claims
- 1. A closure for an inner unit of a wastewater treatment mechanism comprising a cap member having a chamber defined by a top wall, a bottom wall and a peripheral wall therebetween; a first opening for introducing wastewater into said chamber, a second opening for discharging wastewater from said chamber, means defined by said top wall for directing wastewater along an upper surface thereof along a generally radial flow path of limited peripheral extent in a generally radially outward direction, and said wastewater directing means initially directs wastewater from generally opposite points to a point of merger prior to affecting said radially outward direction.
- 2. The closure as defined in claim 1 including a third opening in said top wall for introducing a wastewater treatment medium into said chamber.
- 3. The closure as defined in claim 2 wherein said first opening is in said bottom wall.
- 4. The closure as defined in claim 2 wherein said second opening is located in said peripheral wall.
- 5. The closure as defined in claim 2 wherein said first opening is located in said bottom wall, and said second opening is located in said peripheral wall.
- 6. The closure as defined in claim 1 including means defined by said top wall for locating thereat means for introducing a wastewater treatment medium upon said top wall upper surface.
- 7. The closure as defined in claim 1 including means defined by said bottom wall for converging the flow of wastewater during the flow thereof from said first opening to said second opening.
- 8. The closure as defined in claim 1 including at least one threaded rod means projecting in a direction away from said bottom wall for securing said closure to a container of an outer unit of a wastewater treatment mechanism.
- 9. The closure as defined in claim 1 including means for leveling said closure upon installation thereof relative to an outer unit of a wastewater treatment mechanism.
- 10. The closure as defined in claim 1 wherein said first opening is in said bottom wall.
- 11. The closure as defined in claim 1 wherein said second opening is located in said peripheral wall.
- 12. The closure as defined in claim 1 wherein said first opening is located in said bottom wall, and said second opening is located in said peripheral wall.
- 13. The closure as defined in claim 1 wherein said generally opposite points are generally diametrically opposite each other and said point of merger is located between said generally diametrically opposite points.
- 14. The closure as defined in claim 13 wherein said first opening is in said bottom wall.
- 15. The closure as defined in claim 13 wherein said second opening is located in said peripheral wall.
- 16. The closure as defined in claim 13 wherein said first opening is located in said bottom wall, and said second opening is located in said peripheral wall.
- 17. A closure for an inner unit of the wastewater treatment mechanism comprising a cap member having a chamber defined by a top wall, a bottom wall and a peripheral wall therebetween; a first opening for introducing wastewater into said chamber, a second opening for discharging wastewater from said chamber, means defined by said top wall for directing wastewater along an upper surface thereof along a generally first radial flow path of limited peripheral extent in a generally radially outward direction, and means defined by said top wall for directing wastewater along an upper surface thereof along a generally second radial flow path of limited peripheral extent in a generally radially inward direction and into merger with said first radial flow path.
- 18. The closure as defined in claim 17 including means defined by said top wall for directing wastewater along an upper surface thereof along a generally third radial flow path of limited peripheral extent in a generally radially inward direction into merging relationship with said first and second radial flow paths.
- 19. The closure as defined in claim 18 wherein said first radial flow path has an outlet and said second and third radial flow paths each have an inlet and said outlet and inlets are in peripheral spaced relationship to each other.
- 20. The closure as defined in claim 18 wherein said first opening is in said bottom wall.
- 21. The closure as defined in claim 18 wherein said second opening is located in said peripheral wall.
- 22. The closure as defined in claim 18 wherein said first opening is located in said bottom wall, and said second opening is located in said peripheral wall.
- 23. The closure as defined in claim 17 wherein said first and second radial flow paths have respective outlets and inlets in peripheral spaced relationship to each other.
- 24. The closure as defined in claim 22 wherein said first opening is in said bottom wall.
- 25. The closure as defined in claim 23 wherein said second opening is located in said peripheral wall.
- 26. The closure as defined in claim 25 wherein said first opening is located in said bottom wall, and said second opening is located in said peripheral wall.
