ABSTRACT:
A tube pressure filter including an inner compartment having an inlet which comprises a substantially annular aperture extending around the lower end of the inner tubular body and debouching into the inner compartment. The substantially annular aperture is constructed and disposed so that, in use, feed material debouching therefrom has an upward component of velocity and is in communication with an ante-chamber into which a mixture to be pressure filtered can be introduced under pressure through a feed conduit, the feed conduit containing or co-operating with a non-return valve so as to prevent the flow back along the feed conduit of feed material to be pressure filtered which is under high pressure.
