2137088 9324108 PCTABS00028 Blood comes from the patient (13) through a blood pump (12) through an artificial kidney or membrane cartridge (11) and returns to the patient (14). The dialysate fluid is blended in a proportioning pump (18) by combining treated diluent water (15), acid concentrate (16), and bicarbonate (alkalizer/buffer) concentrate (17). These materials are blended at a machine set dilution rate (36.83X or 45X) to produce a final dialysate stream (19). Final dialysate fluid has at least 1 millimole of added acid. The dialysate fluid stream (19) passes into the cartridge (11) wherein the fluid contacts the exterior of the hollow dialysis membrane containing the blood. The contaminated dialysate (25) leaves the cartridge via pump (26) and directed to a drain.
