wire mesh Leaf Filter
wire mesh Leaf Filter
Our Vertical Leaf Filters are standard equipped filters, that can be used for numerous filtration processes. Both models are pressure filters with vertical filter leafs.
Our vertical leaf filters are available with Horizontal or Vertical tank execution.
Filters can be utilized for dry or wet cake discharge in a completely closed system.
Thanks to it’s unique construction, the filter tank can be easily retracted making the filter plates accessible for the removal of the filter cakes.
Vertical Leaf Filters are suited to processes with a high volume and a high solid content.
All Vertical Leaf Filters can be supplied in automated versions.
The leafs filter on both sides, offering a large filtration area in a relatively small vessel.
The "heavy duty" filter plates consist of a perforated support layer with on both sides a drainage layer and a wire mesh filtration layer. This construction assures sturdiness and durability. It is possible to remove the wire mesh media on location.

Filtration
Once the precoating stage is completed the process slurry is pumped into the filter, the forming cake is retained on the leaves and the filtrate flows to further processing.
When the solids are fine and slow to filter a body-aid is added to the feed slurry in order to enhance cake permeability. However, it should be kept in mind that the addition of body-aid increases the solids concentration in the feed so it occupies additional volume between the leaves and increases the amount of cake for disposal.
Likewise, for all those applications when the cake is the product, precoat and filter-aid may not be used since they mix and discharge together with the cake.
Please refer to the section on Pressure Filters for further details on precoating and the addition of body-aid.
Heel Removal
Once the filtration cycle is completed air or gas is blown into the vessel and the slurry heel that surrounds the leaves is pushed and displaced downwards until it reaches the lowest part of the leaf stack. At this point the remaining heel slurry is evacuated back to the feed tank by a special dip pipe that is located at the very bottom of the vessel so that the vessel is empty from slurry.
The vertical leaf filter consists of a
vertical tank or
horizontal tank and is suitable for wet or dry cake discharge. Wet cake discharge filter models are cleaned by built-in spray pipes. The slurry is discharged through a large bottom drain.
Dry cake discharge filter models are equipped with a pneumatic vibrator. The cake is discharged either through a hydraulic operated quick opening tank bottom or a butterfly valve.
Our filters are reliable filter systems for high volumes with a horizontal retractable filter tank. Thanks to this unique construction, the filter tank can be easily retracted making the filter plates accessible for the removal of filter cake or maintenance. Dismantling of piping/fittings is not necessary due to the retractable filter tank. The filters can be configured for either wet or dry cake discharge.
