Hollow fiber membrane คือ
NettetHollow fiber membranes are fibers of 0.1–1 mm diameter with a hollow space inside ( Fig. 5.1 ). The feed is supplied either inside or outside of the hollow fiber and the permeate passes through the fiber wall to the other side of the fiber. The fiber wall has the structure of asymmetric membrane, the active skin layer facing the feed solution. NettetAn example of a hollow fiber membrane is disclosed in U.S. Patent No. 9,541,302. Examples of hollow fiber membranes are also included in the following products: the LIQUI-CEL MM Series Membrane Contactor from 3M Company (product ID B5005009013) and the LIQUI-CEL SP Series Membrane Contactor Cartridge from 3M …
