Ceramic membrane technology
Spiral-wound membrane technology
Hollow fiber membrane technology
Electroosmosis
Hollow fiber membrane separation technology is a separation technology widely used to separate, concentrate and purify solutions and gaseous materials. It uses thin membranes with permselectivity as the separation media. The membrane wall is filled with microporous pores. Under pressure, the original fluid will penetrate one side of the membrane, and the solvent and small solute will pass through the membrane wall and become percolate. On the other hand, solutes with large molecules are retained by the membrane, so as to achieve the purpose of separation and concentration of the substance.
