Leaf filters, sometimes called tank filters, they consists of flat filtering elements (leaves) supported in a shell. The leaves are circular, arc-sided, or rectangular, and they have filtering surface on both faces. The shell is a cylindrical tank The set-up consists of flat filtering elements (leaves) supported in a slurry tank. A filter leaf consists of a perforated plate over which a filter medium of woven fabric is fitted. The whole assembly is connected to a vacuum pump through a filtrate receiver. An agitator is fitted in the slurry tank. Drain valve is provided in it. The set-up is operated batch wise.
Experimentation:
- To determine the specific cake resistance for the given slurry using Leaf Filter
Utilities Required :
