ABSTRACT:
A filtration apparatus designed to remove solid contaminants from a liquid includes an endless filtration belt located in a liquid tank, so that liquid flows through minute openings in the belt into a liquid collection box located within the belt envelope. Edge areas of the belt are engaged with annular support walls carried by the tank side walls, such that a continuous seal is provided against migration of contaminants around the belt side edges. Contaminants collecting on the belt surface can be periodically removed by moving the belt across a spray system that dislodges the contaminants from the belt into the tank. A drag conveyor removes contaminants from the tank.
