There is a huge variety of filter media available. Textile fabrics, porous foams,
films and sands can be used as filter media. Depending upon the filtration
application different requirements have to be fulfilled. Sometimes it is necessary
to combine different filtration media to fit best the application’s requirements (e.g.
textile filter and film). The choice of the filter medium depends on the properties
of the particles that need to be separated (e.g. particle size, potential for agglomeration,
particle concentration) and the surrounding medium
