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

Vertical Pressure Leaf Filters are used for filtration of liquids with ~7% suspended solids:

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

Applications

Major application of Pressure Leaf Filters is in the filtration of Catalysts, Carbon black, and Bleaching earth in Edible oil processing, Crude oil Bleaching and Post-bleaching, Hydrogenation, Winterisation, and Fractionation
Applications in the chemical and process industry include Aluminates, Fatty Acids, Sulphur, Mining, Brine, Resins, Ni Catalyst, and Electrolytes

MOC

Filtering Mesh is manufactured from SS316L, while the inner meshes and collecting channels of the leaves are manufactured from SS304
The housing and support elements can be manufactured from Carbon Steel, SS304, Monel, Inconel, Carbon Steel, etc. based on customer specifications
Filters can be provided special linings such as SS304/ SS316L for food grade processes, e.g. in Vegetable Oil refining
