ABSTRACT:
An apparatus for scum removal is disclosed wherein toothed paddle induces turbulent effect on the fluids present in the reactor by means of its rotary motion. This results in both breaking and radial displacement of the scum, accumulated on the fluid during the course of the biochemical or chemical reaction, towards the outlet of the reactor, thereby ensuring that the reaction continues in scum free environment uninterruptedly.
