Damage to filter media

Fabric stretch arises in several types of filter, but the cause can depend on the design and operation of the filter. In filter presses and both vacuum and pressure leaf filters stretch may occur as a result of the vertical pull of heavy filter cakes on the cloth during cake discharge in filter presses the stretch can result in portholes in the cloth being pulled out of alignment with the holes
