ABSTRACT OF THE DISCLOSURE A surface skimming system for collecting and removing floating matter from the surface of a circular clarifier. The system includes a rotating skimmer arm, a scum blade and pocket assembly, and a scum baffle. The scum blade and pocket assembly are secured to the outer end of the skimming arm for receiving and directing the outwardly moving floating matter into the scum baffle. The scum baffle is located adjacent the outer periphery of the clarifier tank and includes a scum beach and trough assembly to receive the floating matter collected in the scum pocket. A pair of scum blades are positioned adjacent one another in an over- lapping relationship and are independently biased against the side walls of the scum baffle by flexible support members. The flexible support members are in turn secured to the skimmer arm through a torsion bar so as to permit vertical movement of the scum blades while maintaining a downward bias thereon as they move along the scum beach.
