ABSTRACT:
Apparatus adapted for use in a water clarification system which removes particles of greater than a predetermined size from the clarified water includes a screen or a pair of concentric screens positioned in a clarified water storage area between an inlet and a clarified water outlet. One or more spray heads for direct a shower of high pressure filtered clarified water at the outlet side of the screen or screens to loosen or remove particles therefrom. In addition, a rotating brush can act on the inlet side of the screen. Particles removed by the cleaning elements are recirculated through the system. Water levels are maintained by overflow control or by monitoring the water level and utilizing the output from the monitor or monitors to selectively control valves in the inlet or outlets from the system.
