ABSTRACT:
A cylindrical tank (12) is formed from stainless steel plates. Proximate an open top end (17) of the tank (12) are four evenly spaced mixing assemblies (20). An intake pipe (22) is positioned with an open end (38) below the surface of a biological conversion medium (16) to allow a pump (28) to draw the medium (16) into a receiving box (24). A downcomer (26) merges with the receiving box (24) in order to allow the medium (16) to be injected with a biological conversion component such as air through an inlet pipe (34). The medium (16) and the injected component then pass through a static in-line mixer (30) which thoroughly mixes the medium (16) with the component and creates a multitude of finely-divided air bubbles for circulation and feeding of the medium (16) throughout the tank (12).
