Abstract: An industrial separator and dewatering plant delivers an influent to an inclined rotating filter belt for filtering out solid matter from the influent. A wash water is sprayed on the return portion of the belt to dislodge residual solid matter captured within the belt. A dewatering portion has an auger screw positioned for receiving the solid matter and the wash water. The auger screw transports the wash water and the solid matter to a compression cage where water is driven out of the solid matter by compression as it exits the plant. Alternately, the solid matter and wash water may be delivered together to a plant exit. Excess wash water is able to drain from the auger screw through a separate drain.

Abstract: An industrial separator and dewatering plant has a filtering portion using an inclined conveyor belt for carrying away a watery cake from an aqueous mixture containing solid matter. The filtering portion further has a wash water spray nozzle directed at the conveyor belt so as to dislodge the watery cake penetrated within the conveyor belt. A dewatering portion has a compression auger screw positioned for receiving the dislodged watery cake and the wash water. An auger screw receives the wash water and cake which is transported to a compression cage where compression drives water out of the cake leaving a semi-solid cake which is pressed against a door where it exits the plant.
