Membrane filtration equipment is a device that uses a semipermeable membrane (membrane) to separate, concentrate, and purify substances. It is widely used in water treatment, food and beverage processing, biopharmaceuticals, chemical production and other fields. Membrane filtration technology can be divided into different types according to the pore size and mechanism of the membrane, such as microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO).
Ultrafiltration (UF) is a membrane separation technology that can remove suspended solids, bacteria, viruses, colloids and high molecular substances in water, while allowing water molecules and low molecular weight solutes to pass through. The pore size of ultrafiltration membranes is generally between 0.001 and 0.1 microns.
