Abstract

Ultrafiltration (UF) is primarily a sizeexclusion-based pressure-driven membrane separation process. UF membranes typically have pore sizes in the range from 10 to 1000 Å and are capable of retaining species in the molecular weight range of 300 to 500,000 dal-tons. Typical rejected species include sugars, biomolecules, polymers, and colloidal particles. Most UF membranes are described by their nominal molecular weight cutoff (MWCO), which is usually defined as the smallest molecular weight species for which the membrane has more than 90% rejection.
