Working of Filter leaf:

• The filter leaf is placed in a vessel containing slurry.

• When vacuum is applied, the liquid flows inside the filter through filter cloth, leaving behind the cake on the surface of cloth.

• The cake can be washed by immersing in a vessel containing water or reverse flow of air
