What is Ultrafiltration System?

Ultrafiltration (UF) is a low pressure process for the selective filtration of molecules of a specific size and weight.Substances ranging in size from 1000 MW to 1.000.000 MW are retained by the UF membrane, while low molecular weight compounds, salts and water pass through. UF membranes are typically used for the concentration and recovery of high molecular weight compounds, separation/removal of their contaminants, purification, fractionation of organics and removal of colloids and suspended solids, and are therefore also used as pre-treatment for reverse osmosis.

Ultrafiltration (UF) is a membrane separation technology that can purify and separate solutions. The ultrafiltration membrane system is a solution separation device that uses ultrafiltration membrane filaments as the filtration medium and the pressure difference on both sides of the membrane as the driving force. The ultrafiltration membrane only allows the solvent (such as water molecules), inorganic salts and small molecular organic matter in the solution to pass through, while intercepting macromolecular substances such as suspended matter, colloids, proteins and microorganisms in the solution, thereby achieving the purpose of purification or separation. Ultrafiltration membranes are widely used in water treatment projects. Ultrafiltration technology plays an increasingly important role in reverse osmosis pretreatment, drinking water treatment, and reclaimed water reuse. Ultrafiltration technology plays a key role in the sterilization and turbidity removal of alcoholic beverages and beverages, the removal of pyrogens from drugs, and the concentration of food and pharmaceutical products.
