Abstract
A drum filter assembly comprising a hollow drum filter having a longitudinal axis and an outer filter screen or mesh material, the drum filter being supported on external rollers for rotation about its longitudinal axis and an inlet for introducing liquid to be filtered into the interior of the drum filter. Rotation of the drum filter is effected by the liquid flowing into the drum filter. Alternatively, the drum filter may be driven by an external motor.

13. A drum filter assembly comprising:
-
a hollow drum filter, said drum filter having a longitudinal rotation axis, a pair of end members spaced apart along said axis, said end members having a circular periphery, a plurality of ribs extending between said end members and spaced apart in a circumferential direction, and a circumferentially extending filter screen or mesh material supported by said ribs; a plurality of rollers externally of said drum filter on which said end members are received to support said drum filter for rotation about its longitudinal axis; means for introducing liquid to be filtered into the interior of said drum filter for filtering though said screen or mesh material; and wherein said liquid introduced into the interior of said drum acts against said ribs to effect rotation of said drum filter. - View Dependent Claims (14, 15)
