Filtration

Filtration is the removal of insoluble solids from a suspension by passing it through a porous material. The resulting liquor is termed the ‘filtrate’ and the separated solids are the ‘filter cake’. Filtration is used to clarify liquids by the removal of small amounts of solid particles (for example from wine, beer,oils and syrups).

Equipment

Gravity filtration is slow and finds little application in the food industry. Filtration equipment operates either by the application of pressure to the feed side of the filter bed or by the application of a partial vacuum to the opposite side of the filter bed.
