Ultrafiltration is One of pressure-driven membrane separation technology. Macromolecules and small molecules for the purpose of separation, membrane pore size between 20-1000A °. Hollow fiber ultrafiltration (membrane) having a melting unit High packing density, small footprint advantages.

In the ultrafiltration process, the aqueous solution at a pressure driven flow through the membrane surface, membrane pores smaller than the solvent (water) and small solutes permeable membrane, become decontamination liquid (liquid filtration), larger than the membrane pores and solute solute groups trapped, with the water discharge, a concentrated liquid.

Ultrafiltration process is dynamic filtration, separation is accomplished in the flow state. Solute only limited deposition on the membrane surface, ultrafiltration rate reduction to some extent and tends to balance, and can be restored by washing.

Then in 1748 originated ultrafiltration, Schmidt film or Lu membrane with cotton sub-filter solution, when a certain pressure is applied, the solution (water) through the membrane, while proteins, colloids and other substances were trapped down far more than the accuracy of its filter filter paper, so he made the phrase ultrafiltration, 1896, Martin made a first artificial membrane, which in the 1960s, proposed the concept of molecular level, is the beginning of the modern ultrafiltration, 70's and 80's are rapid development, after 90 years to mature.

Our study of the technology late 1970s, is still in the research period, the late 1980s, before entering the industrial production and application stage.

Ultrafiltration device as reverse osmosis, there is plate, tubular (internal pressure column and external pressure tubular bundle type), roll, hollow fiber form. Concentration polarization membrane separation process but a natural phenomenon, and how to reduce this phenomenon to a minimum, is one of the important issues ultrafiltration technology.

The measures being taken are:

① to improve the membrane surface water velocity to reduce the boundary layer thickness, and make timely solute trapped away from water;

② ② physical or chemical cleaning measures taken.

Ultrafiltration ultrafiltration device generally consists of several components. Generally it can be divided into plate and frame, tubular, spiral wound and hollow fiber four main types.

Since the majority of ultrafiltration treated liquid containing a water-soluble biological macromolecules, organic colloids, polysaccharides, and microorganisms.

These substances easily adhered and deposited on the membrane surface, resulting in serious concentration polarization and clogging, which is the most critical issue ultrafiltration method to overcome concentration polarization, usually can increase the fluid flow, turbulence, and to strengthen an increase in agitation.
