Process Description

Saora’s Ultrafiltration (UF) process is generally a pressure-driven separation process, governed by a screening principle and dependent on filtrate particle size. Saora’s Ultrafiltration membranes utilizes pore sizes between 1 nm and 100 nm, thus allowing retention of compounds with a molecular weight of 300 to 500 000 Dalton.

In general, Saora’s ultrafiltration is suitable for retaining biomolecules, bacteria, viruses, polymers, colloidal particles and sugar molecules.

Our Ultrafiltration membranes are defined by their nominal Molecular Weight Cut-Off (MWCO). The MWCO generally represents the smallest molecular weight for which the membrane has a retention value of more than 90%. However, separation efficiency is not only influenced by cut-off but also by interaction contact with the membrane and the raw solution. The operating pressure for ultrafiltration process is usually between 0.1 and 1 MPa.
The following desired operations are typical for the application of ultrafiltration:
• Filtration of raw solutions
• Concentration of substances
• Fractionating of substances
