Abstract: The sidewall of a rotary filter drum is provided with raised, perforate decking across which is formed a plurality of parallel grooves encircling the drum. Loops of filter medium are trained about the drum and rollers spaced therefrom. The loops are in a single layer and seat in the grooves to thereby be maintained in parallel, spaced-apart relationship. Division strips are provided longitudinally across the drum between sections of the decking to seal against the loops of filter medium between said sections. A circumferential seal is provided about the drum ends to stop leakage from the edges of the decking section while allowing expansion of the decking. An adjustable device is provided for tensioning the loops and for discharging cake therefrom.
