Definition
filtration process in which a membrane filter that is used has pore size in the range of 0.001 to 0.01 ΞΌm
Explanatory Notes
The stated pore-size values indicate the characteristic scale associated with nanofiltration and are not intended to establish exact lower or upper classification boundaries. A membrane filtration process may still be classified as a nanofiltration process when the nominal pore-size rating lies near or modestly outside this interval, provided that the membrane and its retention performance are recognized as nanofiltration.
Examples
- A nanofiltration process is used to remove endotoxins while allowing most proteins to pass through; A nanofiltration process concentrates therapeutic peptides while separating out small salts and solvents; A nanofiltration process is applied after viral inactivation to clear potential viral contaminants; A nanofiltration process is used to reduce water content and impurities in antibiotic purification;
Primitive Class
This class is declared primitive and it does not have necessary and sufficient condiftions defined.
Primitive Rationale
