Abstract
A pressure filter for separating a liquor from mud liquor slurry and for concentrating a filter cake as a heavy slurry discharge comprising a tank having a ring of filter elements supported by a plate which separates the filter tank from a filtrate chamber.

In the backwashing mode of operation the feed rate is maintained or increased to assist in displacing filter cake from the filter elements.
