Abstract:
This paper develops a new approach for the general description of membrane plasma separator performance by using dimensional analysis. Experiments involved cross-flow microfiltration of goats' blood across flatsheet polyvinylidene fluoride durapore membranes of pore size 0.65, 0.45 and 0.22 microns in a thin-channel device. Certain non-dimensional numbers are evolved which represent the grouping of relevant filtration parameters and which contribute to the global characterization of membrane-based plasmapheresis devices.
