Ultrafiltration

Ultrafiltration is a pressure driven membrane separation technologies. Separation ofmacromolecules and small molecules for the purpose of the membrane pore size in the20-1000A °. The hollow fiber ultrafilter (membrane) has a filling unit containers, high density, small footprint advantages.

Ultrafiltration process

Ultrafiltration process, the aqueous solution under pressure-driven flows through themembrane surface, less than the membrane pore solvent (water) and small solutespermeable membrane purification liquid (liquid filtration) than the membrane pore-soluteand solute Group are retained, with the water discharge, a concentrated solution.Ultrafiltration process for dynamic filtration, separation is completed in the current state.The Solute only limited deposition on the membrane surface, the ultrafiltration rate ofdecay to a certain extent and balanced, and can be restored by cleaning.

Origin of ultrafiltration

The origin of ultrafiltration So in 1748, Schmidt Cotton film or Lu membrane filter solution,exert a certain pressure, the solution (water) through the membrane, proteins, colloidsand other substances were interception down far more than its filtering accuracy filter paper, and he proposed ultrafiltration phrase in 1896, Martin, the system out of the firstartificial ultrafiltration membrane, its the 1960s, the concept of molecular scale, is the beginning of modern ultrafiltration in the 1970s and 1980s period of rapid developmentafter the 1990s began to mature. China the technology of late 1970s, is still in theresearch period in the late 1980s before moving on to industrial production and application stages.
