A pumped or gravity flow rotating drum screen removes unwanted solids from a flowing fluid. The drum screen may comprise: a housing having a fluid inlet end, a solid discharge end and an area between the two ends, the fluid inlet permitting a flow of influent containing unwanted solids into a hollow portion of a drum screen positioned lengthwise in the area between the two ends of the housing, the screen comprising a filter medium that retains at least a portion of the unwanted solids within the hollow portion of the drum screen and which produces a liquid effluent that is discharged from an outer surface of the drum screen, the retained solids being removable via the solid discharge end; a drive assembly configured to rotate the drum screen about an axis running the length of the drum screen; and one or more stabilization pad assemblies in contact with one or more rings circumscribing the outer surface of the drum screen at one or more locations.
