ABSTRACT:
A filtering apparatus and method is disclosed adapted to filter suspended solids from a liquid, consisting of a filter housing which receives a flexible belt filtering element into a filter chamber, the liquid to be passed through the belt to filter out solids. The flexible belt is movably mounted to be passed through end openings on either side of a filter chamber to enable removal of accumulated solids after each filter cycle. The end openings are sealed during filtering cycles by flexible tube segments extending across the openings which are pressurized to effect a seal and evacuated to allow removal of the belt. A series of such filters may be stacked together with a traveling roller assembly utilized for simultaneously moving the belts of each filter in and out of the chamber.
