ULTRAFILTRATION MEMBRANES

Ultrafiltration is a variety of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. Ultrafiltration (UF) is basically a pressure-driven separation process, governed by a screening principle and dependent on particle size.

UF’s main attraction is its ability to purify, separate, and concentrate target macromolecules in continuous systems.

Ultrafiltration Mechanism and Properties

Ultrafiltration membranes are defined by their nominal molecular weight cut-off (MWCO). In many cases, however, separation efficiency is not only influenced by cut-off but also by interaction between the membrane and the raw solution. The operating pressure for ultrafiltration is usually between 2 and 10 Bar.

Ultrafiltration has a pore size of approximately 0.001 to 0.1 microns, and therefore solutes including macromolecules, molecular weight of approximately 10,000 to 500,000 daltons, may be purified, separated, or concentrated in either fraction.

Depending on the MWCO of the membrane used, suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane. This separation process is used in industry and research for purifying and concentrating macromolecular solutions, especially protein solutions.

Typically, the process is suitable for retaining biomolecules, bacteria, viruses, polymers, colloidal particles and sugar molecules.
