Filter Press Operation and Features
|
-
Filter Presses in principal are pressure filters in where a filters pack
comprising of a series of plates and frames or chamber plates in compressed
between one fixed and one movable bulk head on the other end. The filter media
is placed between each individual element.
.
-
A pair of filter plates when closed form a cavity internally covered on all both
sides by the filtering medium. Slurry with uniform distribution of finely
dispersed solids in liquid is introduced under pressure in this cavity. Liquid
passes out and solids with remaining discharged through a closed pipe formed in
the plates or is passed out into open channel through externally mounted cocks.
.
-
Once the filter cake is fully pressed and filtrate trickles out, the cake can be
washed to remove any impurities and the cake can be further dried. Thus
solid-liquid separation of a slurry is achieved leaving a filter cake in the
cavity are directed through specially devised nozzles fitted in the fixed end.

-
Cake which has built in the hollow space between the plates will fall our once
the pack is opened.
