This standard adopts the following definitions.
3.1 Ultrafiltration
Ultrafiltration is a technology that simultaneously concentrates and separates macromolecules or colloids. With pressure difference as the driving force, when the liquid flows over the surface of the ultrafiltration membrane, macromolecules or colloids are retained, and small molecules pass through the membrane in the separation process. 3.2 Pure water fluxpurewaterflux
Under certain temperature and pressure, with pure water as the medium, the amount of pure water permeated through the component per unit time. 3.3 Rejection
The mass ratio of a specific component retained by an ultrafiltration membrane component to the total amount of that component in the liquid. 3.4 Retention molecular weight Arweight Under the specified operating conditions, when the retention rate of the ultrafiltration membrane assembly for the standard substance with known molecular weight reaches the design requirements, the molecular weight value of the substance is taken as the molecular weight cut-off of the assembly. It is used to characterize the separation capacity of the ultrafiltration membrane assembly. 4
