Separation and purification Filtration and screening

Separation and purification Separation and purification Filtration and screening: In filtration, a porous material is used to separate particles of different sizes. If the pore sizes are highly uniform, separation can be fairly sensitive to the size of the particles, but the method is most commonly used to effect gross separations, as of liquids from suspended crystals or other solids.

An apparatus for the separation of solids and liquids from a suspension has a hollow drum rotatably mounted about a horizontal axis. The drum wall is a screen made of a plurality of wires, preferably wedge-sectioned wires; spaced apart in a parallel arrangement and lying axially along the drum.

separation is by evaporation and not by mechanical means. The major cost of the drying operation is the cost of the energy, usually in the form of heat, which must be supplied to vaporize the liquid. Because of this most of the liquid should be removed by filtration or centrifugation before the solid is fed to the drying operation. Dryers can be:

Trommel screen Wikipedia

A trommel screen, also known as a rotary screen, is a mechanical screening machine used to separate materials, mainly in the mineral and solid-waste processing industries. It consists of a perforated cylindrical drum that is normally elevated at an angle at the feed end. Physical size separation is achieved as the feed material spirals down the rotating drum, where the undersized material
