Pressurefilters can apply a large pressure differential across the septum to giveeconomically rapid filtration with viscous liquids or fine solids. The mostcommon types of pressure filters are filter press. A filter press contains aset of plates designed to provide a series of chambers or compartments in whichsolids may collect. The plates are covered with a filter medium such as canvascloth. Slurry is admitted to each compartment under pressure; liquor passesthrough the canvas cloth and out a discharge pipe, leaving a wet cake of solidsbehind. Plates and frames sit horizontally in a metal rack, with cloth coveringthe face of each plate, and are squeezed tightly together by a screw. Slurryenters at one end of the assembly of plates and frame. It passes through achannel running lengthwise through one corner of assembly.
Theset up consists of 7 plates and 6 frames. Frames are covered with filter cloth.Feed is fed by gear pump at the top and filtrate collected at the bottom fromeach plate by operating the cock. After removing cake, washing and cleaning canbe done by water provided by overhead tank. Inlet & outlet pressures aremeasured by pressure gauges. Rate of filtrate removals is measured bycalibrated tank provided.
