Slurry is fed into the top compartment from where filtrate passes into the lower chamber en route to receiver.
Solids are deposited on the filtering media in the top compartment and take the shape of cake of a uniform thickness.
The agitator pushes the solid content in the slurry upwards by keeping it under suspension till maximum possible filtrate passes through the filter bed.
This reduces time and increases productivity.
It then seals the cracks in the cake, which develops after most of the filtrate has passed through, by smoothening the top surface of the cake.
