Ultrafiltration is a membrane system that falls between microfiltration and nanofiltration, with an average pore size of 3-100nm. Ultrafiltration membrane is a membrane separation technology that can purify, separate, and concentrate solutions.
Ultrafiltration is a membrane system that falls between microfiltration and nanofiltration, with an average pore size of 3-100nm. Ultrafiltration membrane is a membrane separation technology that can purify, separate, and concentrate solutions. Its retention mechanism is mainly through sieving, but sometimes the membrane pores are larger than solvent molecules and also larger than solute molecules. The chemical properties of the membrane surface also play a role in the retention. The pressure difference on both sides of the membrane is used as the driving force, and the ultrafiltration membrane is used as the filtering medium. Under a certain pressure, when water flows through the membrane surface, only water and low molecular weight solutes are allowed to pass through, thereby achieving the purpose of purification, separation, and concentration of the solution.
