SEPTIC TANK WASTEWATER TREATMENT SYSTEM
First Claim
1. A septic tank system (10, 100, 122) for treating wastewater, comprising:
- a primary treatment compartment (28, 116) having a first inlet (18, 108) for receiving the wastewater and a first outlet (32, 120) for discharging wastewater, the primary treatment compartment adapted to separate from the wastewater therein a portion of at least one of solids and scum; and
a second treatment compartment (34, 141) having a second inlet (40, 140) and a second outlet (48, 152), the second inlet coupled to the first outlet of the primary treatment compartment;
wherein the second treatment compartment (34, 141) is adapted to provide an upflow anaerobic sludge blanket (UASB) wastewater treatment process.

Abstract
A simple and improved septic tank wastewater treatment system is needed to improve effluent quality and reduce conventional onsite system failures such as hydraulic overloading and formation of a clogging biomat in the soil treatment area. One illustrative embodiment of the septic tank system (10, 100, 122) disclosed includes a septic tank system having a primary treatment compartment (28, 116) for settling solids and floating fats, oils and grease, and a second treatment compartment (34, 141) adapted to provide an upflow anaerobic sludge blanket (UASB) process for providing additional treatment of the wastewater prior to discharge to soil treatment areas. Another illustrative embodiment of the septic tank system includes separate primary (100) and UASB tanks (122) coupled in series.
