1) ultra-filtration process

       under pressure, liquid containing the solvent and solute from a variety of small high-pressure feed liquid side reach the low pressure side through the membrane to be called through a fluid or ultrafiltrate; the membrane pore size larger than the solute molecular capsule interception into a concentrate.

2) the ultrafiltration characteristics

        ultrafiltration are pressure-driven membrane processes, membrane separation range of molecular weight of 500-100 million macromolecules and colloidal characteristics of the corresponding particle diameter of 0.005-0.1μm; separation mechanism is generally believed that mechanical sieve ultrafiltration membrane with sub-plate, roll, tube, capillary and hollow fiber filter of several forms of cross-flow filtration methods generally.
