Filter bags for liquids are effective in removing particulate contaminants in the processing of a wide variety of materials. Bag filtration is a pressure-driven operation, wherein the product to be…

The flat elements employing a thick filter medium and working by depth filtration, are distinguished here, as filter pads, from those using thin sheet media and working by surface filtration,…

The pad filter (often called a cassette) is a special case of the range of panel filters, all of which are made in standard sizes, to fit air-conditioning installations. The…

The requirements for dust filtration vary considerably with the particle size of the dust material, and with its concentration in the suspending air or gas (and also with the velocity…

From the complexities of the centrifugal filter, the Handbook moves on to one of the simplest forms of filter, used mainly for dust removal from air, in ventilating situations. These…

The moving bed centrifuge with a cylindrical basket is known as the pusher centrifuge, and is one of the most common types of centrifuge for separating fast-draining crystalline or fibrous…

There are two main designs of moving bed centrifuge: those with a cone-shaped basket and those with a cylindrical basket. In the latter, solid movement needs mechanical assistance, but in…

The fixed bed centrifugal filter is thus a batch-operated device for recovering solids from liquid suspension. All types have cylindrical baskets, open to the atmosphere (or to the enclosing casing)…

Centrifugal separations are of two broad kinds, those using filtration and those operating by sedimentation. The latter are covered in Section 7, while centrifugal filters are the subject of this…

The vacuum belt filter employs a continuously moving horizontal belt of filter medium, commonly of woven wire mesh, moving between two rollers. In the forward direction, a suspension, of medium…
