Chapter 3 Separation Processes (Unit operations)

3.3. Filtration and centrifugation (solid-liquid separation) Filtration is the mechanical separation of solid particles from a fluid by passing the fluid through a filtering medium, or septum, on which the solids are deposited. The most common filtering medium is fabric cloth with strong mechanical properties. The fabric causes the solid particles to become entangled on the surface of the cloth, resulting in the formation of a layer of solids, and the buildup of the solids on the layer. Filtration separation …
