Abstract

An oil or grease removal assembly of the type used to remove such contaminants from the surface of a body of water includes a rotatable disk made of plastic or other material to which such oil contaminants have an affinity, disposed in cooperative relation to an elongated trough having scraper blades for engaging the opposite sides of the disk for the removal of the oil contaminants therefrom with the trough disposed and structured to direct such oil contaminants away from the disk and the body of water such as to an outlet chute during the continuous rotation of peripheral driving of the disk. The trough has a hook-like element to permit it to be removably mounted straddling the disk.
