Vertical pressure leaf filter for oil liquid
Vertical pressure leaf filter is liquid filtration system consisting of many leaf-shaped filter elements that are stacked inside a vertical vessel.
Vertical pressure leaf filter has been specifically designed to provide a large filtration area which is made possible due to the shape of their filter leaf elements. These vertical pressure leaf filter systems produce high filtrate clarity after the clarification run. Different types of filter aids can be used in vertical pressure leaf filters to improve filtrate quality.
Advantage of vertical pressure leaf filter
- Filtration rates are 2-3 times higher on same filter area of plate & frame filter.
- Stainless steel filter elements, hence no repetitive cost, washing and maintenance of filter cloth.
- Automatic cake discharge in very short time without opening the filter from top, hence large saving in labor and time.
- Very low % of unfiltered liquid retention in cake.
- Closed & pressurized operating system hence no spillage & loss of liquid, which helps in handling volatile / inflammable liquids & clean working environment. Entire filtration cycle with cake discharge can be completed without even opening the filter from top.
- Compact & light hence large saving in floor area & supporting structures.
- Pressure leaf filter can be completely automated with no human intervention.
- Vertical pressure leaf filter can be used for getting filtered liquids as well as cake.

Leaf Filters are ideal for solid-liquid separation & work on principle of precoating & pressure.
Pre-coating is done with the help of suitable filter aid about 0.5 to 1% (Bleaching earth, supercel, hyflo, superflo etc.) mixed with the liquid to be filtered. Unfiltered liquid is pumped into the filter vessel. Initially the filter aid starts forming a precoat layer on both sides of the filter leaves, until then cloudy material comes out of the filter. Once the layer is formed, pressure starts developing, restricting the impurities. Clear liquid flows from both sides into the leaves (filter elements), flows along the tubular channel & gets discharged from bottom of the leaf. All the leaves are mounted on a common manifold. The leaves start getting choked on both the sides by impurities forming cake, which is in wet from. Once the leaves get choked completely, the pressure rises to 3 kg/cm2 & the output flow almost stops. This means the batch size is reached. The pump is stopped & steam / air pressure is applied from the top (without dropping the filter pressure) to filter the material around the leaves held up in the tank & to squeeze the cake further & reduce the liquid retention in it. The holdup unfiltered liquid in the conical portion is taken back.
Leaf Filter Elements
Pressure leaf filter elements are essential components of pressure leaf filters, which are widely used in various industries for liquid-solid separation. Pressure leaf filters consist of a vertical or horizontal vessel with a number of filter leaves inside. The leaf filter elements - filter leaves are made of stainless steel or other corrosion-resistant materials and have fine pores that allow the liquid to pass through while retaining the solid particles. The leaf filter elements are arranged in a vertical or horizontal configuration inside a pressure vessel. The vessel is filled with the slurry (the mixture of liquid and solid particles) to be filtered. The pressure inside the vessel forces the liquid to flow through the mesh, leaving behind the solid particles on the surface of the leaf filter elements. The solid particles form a cake that can be removed by backwashing, scraping, or vibrating the leaf filter elements.
- High filtration capacity: Leaf filter elements can handle large volumes of slurry with high solids content and viscosity.
- High filtration efficiency: Leaf filter elements can achieve high clarity and purity of the filtrate by removing fine particles and impurities.
- Low maintenance: Leaf filter elements are easy to clean and replace, requiring minimal downtime and labor.
- Long service life: Leaf filter elements are resistant to wear, corrosion, and temperature variations, ensuring reliable performance and durability.
- Customization: Leaf filter elements can be customized according to different specifications, such as size, shape, material, pore size, etc.
