Microfiltration

The pressure-driven membrane process: About microfiltration

Microfiltration (MF) is used to remove all of the substances in water that are larger than the pore size of the membrane. Microfiltration membranes remove particles and colloidal suspensions. The pore size varies between 0.05 and 10 µm.

A characteristic feature of microfiltration is the tangential flow over the membrane, which is referred to as cross-flow filtration. This means that the water does not pass straight through the membrane, but instead flows over the membrane. The cross-flow mode also has a cleaning effect on the membrane, significantly extending the service life of the filtration system.
