3 Terms and Definitions
GB/T 20103-2006 define the following terms and definitions apply to this document. For ease of use, repeat the following list
GB/T 20103-2006 some terms and definitions.
3.1
UF ultrafiltrationmembrane
Starting from a very thin layer separating action of the epidermis and a thicker play a supportive role sponge or fingers porous layer, having a molecular weight cut
Film several hundred to several million.
[GB/T 20103-2006, the definition 5.1.1]
3.2
Pure water permeability purewaterpermeability
Predetermined flow rate, temperature, pressure, water in unit time through unit area of \u200b\u200bmembrane permeation rate.
[GB/T 20103-2006, the definition 5.1.3]
3.3
Dead-end filtration dead-endfiltration
Pressure driven, feeding solvent and solute membrane pore size of less than permeate through the membrane, and the membrane pore size is greater than the feed solute trapped on the membrane surface,
And with the accumulation of a filtration time operating mode.
3.4
Cross-flow filtration crossflowfiltration
Pressure driven, parallel to the film surface feed flow (tangential flow), feeding solvent and solute membrane pore size is less than the vertical permeate through the membrane (vertical
DC), and the feed is greater than the pore size of the solute is trapped and go with the flow of the remaining A method of operation.
