The clearance of a dialyzer at zero ultrafiltration and zero inlet concentration in the dialysate was studied for varying dialysate flows. It was found that a practically feasible limit can be set to the dialysate flow, above which the gain in clearance is minimal or negligible, resulting more in a waste of dialysate than in increased mass transport. The results suggest a more economical operation of dialyzers, which is of general interest, as well as of special interest in areas where no on‐line dialysate preparation is used (e.g., because of unreliable water supplies).
