  • Ultrafiltration membrane is a microporous filtration membrane with a consistent pore size specification and a rated pore size range of 0.01 microns or less. 
  • Appropriate pressure is applied to one side of the membrane to screen out solute molecules smaller than the pore size to separate particles with a molecular weight greater than 500 Daltons (atomic mass units) and a particle size greater than 10 nanometers. 
  • The ultrafiltration membrane is one of the earlier developed polymer separation membranes, and the ultrafiltration device was industrialized in the 1960s. 
  • Target products with different molecular weights can be separated to replace traditional activated carbon decolorization, resin impurity removal, crystallization extraction, and other purification processes to achieve the purpose of decolorization, impurity removal, and product classification. 
  • From the perspective of the configuration of membrane elements, the most widely used are mainly roll type, tubular type, etc.
