A deck structure is described for a filtering apparatus having a rotatably mounted, generally cylindrical drum with filtering and vacuum drainage capability. The deck structure includes the following components: (1) a plurality of circumferentially spaced, axially extending, imperforate channel members affixed to the outer peripheral surface of the drum, the channel members each including a first peripherally extending surface which is radially spaced from the peripheral surface of the drum, the first surfaces defining filtrate slots which are at least about as wide in a circumferential direction as the first surfaces; (2) a plurality of axially extending, evenly circumferentially spaced dams mounted adjacent the outer periphery of at least some of the channel members, the dams defining filtrate compartments therebetween which lead to the vacuum drainage apparatus; and (3) a perforate support for supporting a filter above the filtrate compartments.
