Pressure Leaf Filters

Listing ID #3665915

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, super flo 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 form. Once the leaves get chocked completely, the pressure rises to 3-4 Kgcm² & the output flow almost stops.
