ABSTRACT:
A filter apparatus and method use a permanent filter media belt to support a disposable filter media strip which are indexed over a vacuum chamber perforate cover plate at the bottom of a tank containing liquid to be filtered. A flight conveyor frictionally engages the disposable media strip to index both the disposable media strip and the permanent media belt. The side edges are each extended out into a seal enclosure containing an inflatable tube seal, each pressurized to seal the side edges during filtration, the tubes depressurized when the media are indexed.
