Filter Press [68]

Filter press (sometimes called Plate-and-Frame Filter press) which describes the style of filters developed from the 1800's onwards. The majority of today's filters are more correctly called “chamber filter press”, “Membrane filter press”, or “Membrane Plate Filter". Many processes in the food, chemical or pharmaceutical industries make products from liquid-solid suspensions or slurries. These mixtures are a little like a runny mud or milk-shake. The solids in them do not dissolve in the liquid but are carried along in it. Filter presses separate the solids from the liquids so that the useful part can be processed, packaged or delivered to the next step.Filter presses generally work in a "batch" manner. They are loaded with slurry before completing a filtering cycle and producing a batch of solid filtered material, called the filter "cake". The solid is removed, the press re-loaded with slurry and the filtering cycle repeated. A filter press uses increased pressure to maximize the rate of filtration and produce a final filter cake with a low water content. This is more efficient than filtration using a funnel and paper which utilizes the low pressure caused by the weight of liquid above the filter paper.
