Class Information
Number: 210/650
Name: Liquid purification or separation > Processes > Liquid/liquid solvent or colloidal extraction or diffusing or passing through septum selective as to material of a component of liquid; such diffusing or passing being effected by other than only an ion exchange or sorption process > Diffusing or passing through septum selective as to material of a component of liquid > Filtering through membrane (e.g., ultrafiltration)
Description: Process in which a liquid is passed through a skinlike barrier which serves to retain dissolved or colloidally suspended matter, passing only those constituents which are, per se, fluid, e.g., solvent.
