ABSTRACT:
A filter-thickening apparatus including a thickener tank having tubular filter units suspended therein is disclosed. A liquid-solids suspension is supplied to the tank and an overflow pipe is spaced in a filtrate compartment above the filter units for draining a filtrate liquid from the tank. The filter units preferably include either an accumulator grating or a filter cloth which is sealed along narrow bands to form a pattern of filtering areas or both. Processes for filtering the liquid-solids suspension are also disclosed.
