ABSTRACT:
An apparatus and method are shown for treating waste sludge. The apparatus includes a mixer housing having an elongated mixing auger therein. The housing has an inlet opening and an outlet opening with the elongated mixing auger being rotatably mounted within the housing between the inlet and outlet openings. A sludge conveyor supplies waste sludge to the inlet opening of the elongated mixer housing. An additive hopper contains an additive material to be combined with the sludge introduced within the mixer housing. A metering auger and series of spaced delivery conduits gradually introduce the additive material over a substantial interval of the mixing chamber beginning at a point downstream of the inlet opening to the mixer housing.
