Membrane ultrafiltration in multipass hollow-fiber modules

, 2010
Rising fluid velocity in the fiber tubes of a hollow-fiber module has two conflicting effects. One, the decrease in resistance to permeation due to reduction in concentration polarization, is good for ultrafiltration, while the other, the decrease in ...
