Pressure Leaf Filters

PRESSURE LEAF FILTERS (PLF)

Vertical Dry / Wet Cake Discharge

Pressure leaf filters are used for polishing process streams containing low weight percent solids. These filters consist of a vertical or horizontal pressure vessel with a number of vertically mounted filter leaves. The leaves filter on both sides enabling a large filtration area in a relatively small vessel and plant footprint.

 

VERTICAL PRESSURE LEAF FILTER

This economical type of filter is equipped with vertical rectangular filter leaves. The filter leaves are mounted vertically and connected to a filtrate manifold at the bottom of the filter tank.

Pressure leaf filters are equipped with a pneumatic vibrator for dry cake discharge and the cake is discharged through a large diameter cake clean-out door.

A butterfly valve, slide valve or a specially designed cake door is used for cake removal depending on the process conditions.

For wet cake discharge, the pressure leaf filter is equipped with an oscillating sluice pipe positioned above the filter leaves.
