Abstract

Liquids are filtered on an ind scale in a vessel which is divided into an upper, inlet compartment and a lower, outlet compartment by a transverse partition having transfer ports fitted with filter elements in the upper compartment; this construction is improved by inclining the partition sharply to the horizontal with its lowest point leading into the mouth of the filter inlet. Sludge dislodged from the elements by backwashing rolls down the partition because of the gradient. The ensures complete and rapid elimination of sludge from the inlet compartment.
