Treatment flow: 0,5 m3/h – 500 m3/h

Ultrafiltration (UF) systems are a type of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. Suspended solids and high molecular weight solutes are retained, while water and low molecular weight solutes cross the membrane. This separation process is used in industry and research to purify and concentrate macromolecular solutions (103-106 Da).

Ultrafiltration is not fundamentally different from other processes such as microfiltration, nanofiltration or gas separation, except for the sizes of the molecules which retain. Ultrafiltration is applied in cases of cross-flow or dead-end flow.
