Transport Behavior of Asymmetric Polyamide Flat Sheet Membranes and Hollow-Fine Fibers in Dialysis-Oor all the salts used. Depending on the membrane sample, even values beyond 0.9900 are obtained for the different salts. The experimental findings clearly demonstrate that there is no qualitative nor quantitative difference between flat sheet membranes and hollow-fine fibers if the comparison is mad

Ultrafiltration in an Unstirred Batch Cell of the diffusion coefficient for BSA at pH = 4.70 and pH = 7.40 is small. This finding is further confirmed by separate diffusion coefficient determinations by ultracentrifuge technique. The values of C. as determined from ultrafiltration data are 37.0 g/100cc at pH 4.7 and 57.5 g/100cc at pH 7.4.

The steady state solvent flux behavior of both systems conform to those of total retention membranes with respect to the gel-polarized region as well as the pre-gel-polarized region. The solute retentions depend o

Electrophoretic Techniques for Controlling Concentration Polarization in Ultrafiltration fluxes were 75% to 500% higher than normal ultrafiltration fluxes. Selectivity was also improved as indicated by a 2 to 6 fold increase in the separation factor for solutions of proteins. These preliminary results are analyzed in terms of the important process variables.
