Fabric filtration is a physical separation process in which a fluid, either a gas or a liquid, containing solids is passed through a porous fabric medium, which retains the solids. This process operates in either a batch or semi continuous fashion since it is periodically necessary to remove the retained solids from the filtering medium. There are also filtration systems that are designed to operate in a continuous manner. As with other filtration techniques, it is usually the built-up solid cake that actually performs the filtration; therefore, it is important that an initial layer of deposit be formed at the beginning of the filtration operation.
