Abstract: Apparatus for reducing the solids and oil/grease components of a water mixture includes a tank for holding a water mixture for a period during which heavier-than-water components of the water mixture settle to the bottom of the held water mixture and lighter-than-water components rise to the top of the held water mixture. It includes devices for separating solids from liquids in a flow of solids and liquids and for separating oil/grease from water in a flow of oil/grease and water. A first discharge line from the tank adjacent the location of the heavier-than-water components communicates with the device for separating solids from liquids, and a second discharge line from the tank adjacent the location of the lighter-than-water components communicates with the device for separating oil/grease from water. A third discharge line from the tank intermediate the first and second discharge line is provided for the removal of water with reduced solids and oil/grease components.

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.

Abstract: A strainer assembly for separating solid particles, such as food particles, from drain water includes a straining apparatus made up of discrete portions which travel on an endless path with the path having platform and dumping segments. Incoming drain water impacts the discrete portions of the straining apparatus in the platform segment so that the solid particles are held on the discrete portions while water passes to the drain and the solid particles travel with the discrete portions to the dumping segment, where they are dumped to a collection facility.
