Abstract:
A process for dewatering sludge on a flight of a foraminous filter belt that moves in a substantially longitudinal direction between sludge deposit and sludge discharge positions is disclosed herein. The process includes the steps of depositing sludge on the belt flight at the deposit position; moving the flight with the sludge deposited thereon in a substantially longitudinal direction toward a position in which the sludge is discharged from the belt; initially elevating and mixing the sludge as it is carried by the belt by inserting in the path of movement of the sludge on the belt a plow having a side wall on which the sludge can ride up and be elevated as it is carried by the belt, the side wall extending to a position is proximity to the belt and forming an exterior angle with the belt; again elevating and mixing the sludge as it is carried by said belt at a second position downstream of the initial elevating position by inserting in the path of movement of the sludge a plow having a side wall on which the sludge can ride up and be elevated as it is carried by the belt, the side wall at the second positioned forming an exterior angle with the belt smaller than the exterior angle formed by the side wall at the initial elevating and mixing position; and advancing the sludge past the second elevating and mixing position and discharging the sludge from the belt flight.
