ABSTRACT:
A bioreactor apparatus for processing waste, comprising a cylindrical pressure vessel having an inlet end and an exit end, an internally rotating main shaft having spaced apart ends, and a plurality of paddles and agitator bars attached to and extending radially from the shaft. At least some of the plurality of paddles and/or agitator bars extend radially outward from the shaft and form a helical spiral pattern when viewed from either of the spaced apart ends.
