Abstract: A removable filter plate for a rotary drum filter that reduces instances of welding to secure the filter plate to the drum and obviates the need for cap strips. An exemplary filter plate assembly in accordance with this disclosure comprises a filter plate and an engagement assembly, wherein the engager of the engagement assembly is configured to extend in a lateral direction toward the leading end or the trailing end of the filter plate, wherein an extended engager having an engagement end disposed under a shelf of the adjacent top hat mounting assembly defines a closed position, and wherein a retracted engager defines an open position.
