Abstract

A filtration apparatus for filtering and separating solids from liquids is provided that includes at least one liquid-permeable, continuously or intermittently drivable filter belt, an intake for charging the liquid/solid mixture to be filtered onto the filter belt in a charging zone and a belt cleaner for removing the solids deposited at the filter belt from a belt section conveyed out of the charging zone in an expulsion zone. The belt cleaner has at least one rotatingly drivable brush with which a brush cleaner having a scraper is associated which is arranged in the path of the bristles of the rotating brush. The rotating brush efficiently removes the deposited solids from the filter belt, while the scraper of the brush cleaner simultaneously ensures that the dissolved solids do not settle at the brush and clog it.
