Filtratietypes
Filtratietypes refer to the different kinds of filtrates produced in filtration processes. In filtration, the liquid that passes through the filter medium is called the filtrate; the portion held back by the filter is the retentate. Filtrates thus vary in clarity, composition and the particles they carry, depending on the method, media and operating conditions used.
Filtration methods influence filtrate quality. Gravity filtration relies on filtering by gravity through a porous medium,
Membrane filtration defines filtrate types by pore size. Microfiltration uses pore sizes about 0.1 to 10 micrometers
Terminology: in membrane filtration, the filtrate is often called permeate, while the retained stream is the
