Hollow
fiber ultrafiltration membrane
is one of the most natured and advanced ultrafiltration technologies.
The outer diameter of the membrane is 0.4-0.6mm, inside diameter
is 0.3-0.5mm. The micropores distribute around the wall of
the membrane. The entrapping molecular weight scale is about
several thousand to ten thousand. The water flow from the
outside of the membrane to the inside, it is outer pressure
type. In adverse, it is inside pressure type. The ultrafiltration
is a dynamic process, and the entrapping matter can be drained
out following the concentration water. |
