Leaf Filter

A Vertical Pressure Leaf Filter consists of a hermetically sealed tank with vertical filter leaves mounted on a central manifold at the bottom
Each filter leaf is made from 5 layers of wire mesh – 2 outer filtering layers and 3 inner support layers
Outer layers of fine wire mesh are selected depending on the application - these act as the primary filtering elements and eliminate the need for filter cloth
Inner layers of coarser mesh support the outer layers and serve to collect and discharge the filtrate
Filter cake is discharged from the bottom of the filter using a pneumatic vibrator to shake the leaves
Cake discharge outlet is provided with a Butterfly valve that can be pneumatically controlled from a remote location, or with a wedge lock full opening valve with heel leaf
Vertical Pressure Leaf Filters are self cleaning and simple to operate without need for repeated opening of the filter body
The entire filtration cycle can be easily automated by using a PLC to switch between the priming, filtration, and cleaning steps at regularly timed intervals or based on pressure readings inside the filter
