The Grit & Grease removal system from Schreiber consists of two rectangular concrete channels that separate and collect grit and grease. One channel settles particles while the other collects grease. A rotating spiral flow pattern washes organics from the grit, then deposits it in a trough at the bottom of the channel. A grit pump mounted to a traveling bridge then pumps the grit to an elevated trough sloped at one end to transfer the slurry to a classifier for further washing and dewatering. Floating grease is transported to one end of the channel by an air skimming system. Air is directed onto the surface of the grease channel in the direction of a rotating screw conveyor. The screw conveyor rotates, lifting the grease for disposal in a collection container. 205/655-7466; www.schreiberwater.com.
