Abstract:
Apparatus for separating solids from a first liquid by passing the first liquid through sheet filter media, said apparatus comprisinga vessel for receiving first liquid,a chamber for receiving filtered liquid from the first liquid in the vessel under pressure assisted flow, said chamber being located at least in part below said vessel,a perforate plate separating said vessel from said chamber, said perforate plate being adapted for supporting the filter media, said perforate plate having a first end laterally spaced from a second end,an indexing mechanism for advancing the filter media along a first direction from said first end of said perforate plate to said second end of said perforate plate,a differential pressure generator for establishing a pressure differential between first liquid in said vessel and filtered liquid in said chamber and sufficient to move liquid through the filtering media into said chamber, anda control element coupled to said indexing mechanism means and said differential pressure generator for terminating the pressure differential during the advance of filter media by said indexing mechanism.
