Patent ID: 7892424

Claim:
An apparatus for treating sewage, the sewage including water and waste products, the apparatus comprising: a housing; a sewage receiver compartment formed within the housing, the sewage receiver compartment having a sewage inlet to receive the sewage therefrom, the sewage receiver compartment having a bottom portion, some of the waste products in the sewage to sink to the bottom portion to form a solid matter deposit; a first treatment compartment formed within the housing, the first treatment compartment being in fluid communication with the sewage receiver compartment, the first treatment compartment to receive the sewage from the sewage receiver compartment; an auger mounted within the housing, the auger having first and second ends, the first end being disposed at the bottom portion of the sewage receiver compartment; a receptacle disposed outside the sewage receiver compartment, adjacent the second end of the auger; a rotatable shaft mounted in the housing, the rotatable shaft extending through the first treatment compartment, the rotatable shaft having a biological contactor material secured thereto, the biological contactor material being disposed in the first treatment compartment; a turbine compartment formed within the housing in fluid communication with the first treatment compartment; a turbine rotatably mounted in the turbine compartment and operationally connected to the rotatable shaft and to the second end of the auger; an air source operationally coupled to the turbine, the air source to turn the turbine, the turbine to rotate the rotatable shaft, the biological contactor material successively passing though the sewage, and through air, as the rotatable shaft rotates, the successive passage of the biological contactor material through the sewage and through the air causing micro-organisms to form on the biological contactor material and to consume a portion of the waste products present in the sewage, to produce treated water, the turbine also to rotate the auger, the auger to displace, upon rotation, the solid matter deposit from the bottom portion of the sewage receiver compartment to the receptacle; and an outlet in fluid communication with the first treatment compartment, and with a leach field, to output the treated water to the leach field.
