Abstract
A filter for removing solids from a liquid of the type wherein a rotatable basket or drum has media inside straining from inside out. A power operated conveyor is mounted in the drum above the axis of rotation for receiving and positively removing solids. Thus, a liquid level is possible above the axis of rotation but below the conveyor so that a large filter area is in contact with the liquid while not interfering with the operation of the conveyor. A retractable scoop is provided for positively delivering the solids to the conveyor.
