WebJan 21, 2016 · Convection ; Adsorption; The major mechanisms of dialysis use all three, but to varying extents, depending on the method. Diffusive removal depends primarily on the creation of a concentration gradient … WebCan be either by dialysis, hemofiltration, or a combination. Dialysis involves diffusion of solutes across a semipermeable membrane according to concentration gradients. … WebUnfortunately, the efficiency of convection-based dialysis treatment, or hemofiltration (HF), was limited by the relatively low ultrafiltration coefficient of the dialyzers available at the time. Thus, the exchanged volume was low, and the corresponding clearance of low-molecular-weight solutes was insufficient with respect to the current ... portland or title companies
