This study aimed to investigate the effects of ultrafiltration rate (Q\n                    <jats:sub>F<\/jats:sub>\n                    ) or alternately the substitution fluid flow rate (Q\n                    <jats:sub>S<\/jats:sub>\n                    ) and the membrane surface area of a diafilter on solute removal efficiency for solutes of varying molecular weights, using both experimental and theoretical analysis, and to clarify the mechanism of solute removal in this treatment. Experiments were conducted with three diafilters of different membrane surface areas (1.1, 1.5, and 3.0\u2009m\n                    <jats:sup>2<\/jats:sup>\n                    ) in aqueous and bovine blood systems, varying Q\n                    <jats:sub>F<\/jats:sub>\n                    (=Q\n                    <jats:sub>S<\/jats:sub>\n                    ) from 0 to 400\u2009mL\/min. The parameters required for the theoretical calculation were determined by experiments. In aqueous system, clearances for three solutes (creatinine, vitamin B12, and inulin) obtained by the theoretical calculations corresponded well with the theoretical calculations, showing how the solute removal was depending on the diffusion and convection. In blood system, however, membrane fouling significantly impacted solute clearances, particularly in diafilters with smaller membrane surface areas or higher Q\n                    <jats:sub>F<\/jats:sub>\n                    (=Q\n                    <jats:sub>S<\/jats:sub>\n                    ), leading to deviations between experimental and theoretical values.
