    Abstract: An apparatus having a bowl-shaped screen with a large opening at the upper end thereof and a smaller opening at the lower end thereof for screening annularly distributed influent. An influent manifold is located above the screen to distribute influent downwardly into the upper opening. An effluent receiver is positioned about the screen while a concentrate receiver is positioned below the lower opening of the screen. A distributor cone is positioned in the upper opening to direct influent outwardly and downwardly to the screen. The cone is vertically adjustable to vary the size of the annular opening between the cone and the screen. The cone is also rotatably mounted to aid in uniformity of distribution. A tangential influent feed is employed to induce rotation of the distribution cone. A rotatably mounted backspray manifold extends about the screen with nozzles directed to induce rotation of the manifold. A wiper blade extending to the lower opening of the screen is attached to the backspray manifold for inducing concentrate into the concentrate receiver.
