Abstract
Filter apparatus for continuously separating filterable mixtures, such as fluid-solid or fluid-fluid mixtures, includes a closed loop tubular enclosure having an inlet, at least one filter section spaced downstream from the inlet, and a plurality of longitudinally spaced driving disks within the enclosure mounted for movement downstream therearound, the driving disks preferably being driven downstream through the enclosure by fluid flow from the inlet to the filter section for discharging at least a portion of the fluid. A backflow preventing portion of reduced inner cross section area may be provided upstream from the inlet and a residual material outlet may also be provided.
