TFF
Tangential Flow Filtration (TFF or crossflow filtration) refers to a filtration process where the feed stream passes parallel to the membrane face as one portion passes through the membrane (permeate)…
modes of filtration
The following are commonly used modes of filtration. 1. Direct Flow Filtration (DFF): or "dead-end" filtration is where the feed stream is applied perpendicular to the membrane face, attempting to pass…
ultrafiltration
Ultrafiltration is a form of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. Suspended solids and solutes of high molcular weight are retained, while water and…
debth filters
Depth filters refers to the use of a porous medium that is capable of retaining particulates throughout its matrix rather than just on its surface. These filters are frequently employed…
