Abstract:
A filtering apparatus for separating solids from a liquid, the apparatus comprising a plurality of individual filter elements (4) disposed to be displaced along an endless path (16) having upstream and downstream portions and upper and lower curved portions joining the upstream and downstream portions, the lower curved portion and part of the upstream and downstream portions being immersed in the liquid from which the solids are to be separated, said endless path (16) including a stationary endless element extending along said path and having an arcuate cross-section, said filter elements (4) being disconnected from one another and being individually slidably displaceable along said endless element, said filter elements having respective guide elements which abut against one another in said upstream and downstream portions and in said lower curved portion, drive means along said endless path for engaging successive filter elements one by one to displace the filter elements individually past a scraper device and then advance all of the other filter elements along said endless path.
