Overview

Ultrafiltration is a pressure-driven membrane separation process that uses a semipermeable membrane of defined pore size to separate dissolved and suspended species according to molecular size and shape. Under applied transmembrane pressure, solvent and low-molecular-weight solutes pass through the membrane as permeate, while larger molecules such as proteins, polysaccharides, colloids, and macromolecular aggregates are retained as the concentrate. Membranes are characterized by a molecular-weight cutoff, which describes the size above which species are predominantly rejected, placing ultrafiltration between microfiltration and nanofiltration in the spectrum of membrane techniques. Performance is governed by membrane material and morphology, applied pressure, crossflow conditions, and phenomena such as concentration polarization and fouling, which reduce flux and must be managed through module design and cleaning. Ultrafiltration is widely applied to concentrate, fractionate, and purify macromolecules, to clarify and sterilize fluids, and to recover valuable components or remove contaminants in water treatment, food and beverage processing, biotechnology, and pharmaceutical manufacturing. It is also used analytically and preparatively to separate proteins and enzymes from smaller solutes and to exchange buffers through diafiltration. Research on ultrafiltration spans membrane materials and fabrication, transport and fouling behavior, process optimization, and applications in purification, concentration, and the treatment of biological and industrial fluids.
