Ultrafiltration is a membrane filtration process used to separate molecules based on their molecular weight. In this process, a semipermeable membrane with pores of a specific size is used. When a pressure gradient is applied across the membrane, solvent and small solutes pass through, while larger molecules are retained. The pore size of the membrane dictates the cutoff molecular weight, meaning that molecules larger than this weight will not permeate.

This technology finds widespread application in various industries. In water treatment, ultrafiltration is employed to remove suspended solids, bacteria, viruses, and other microorganisms, producing high-purity water. It is often used as a pre-treatment step for reverse osmosis or as a standalone purification method for potable water. In the food and beverage industry, ultrafiltration is utilized for concentrating proteins, clarifying juices, and de-fatting milk.

The medical field also benefits from ultrafiltration. It is used in hemodialysis to remove excess fluid and waste products from the blood of patients with kidney failure. In biotechnology, it plays a role in protein purification and the concentration of biological samples. The efficiency and selectivity of ultrafiltration make it a valuable tool for separation and purification tasks across diverse scientific and industrial domains. The process is driven by transmembrane pressure, and the selectivity is determined by the membrane's pore size distribution and the size of the molecules being separated.
