An improved drum structure for a corrugated deck type rotary drum filter is provided that increases filter efficiency by eliminating transverse filtrate flow in the drain channels of the drum. Each drain channel is divided into sub-channels using at least one solid grid. The sub-channels drain into a single bucket associated with the drain channel. A drain slit is provided above each sub-channel in the corrugated material that covers the outer surface of the drum.
