A novel approach is reported for the removal of ammonium formed from the conversion of urea by urease. By alkalinization, ammonium is converted into free ammonia. Free ammonia can then be very easily removed by a number of approaches: as gaseous ammonia by air bubbling, oxygenator, or air ventilation; by adsorbent for free ammonia; or other approaches.
The present work is concerned with the calculation of NaCl transfer in flowing solutions and its dependence upon flow characteristics at hemodialyzers. A theoretical analysis of the solute transfer in a hemodialyzer is presented. Experiments were carried out with a continuous flow flat-plate dialyzer. Permeability of cuprophane membranes were calculated both for pulseless and pulsatile flows. It was found that the membrane permeability increases with flow rate but the asymptotic value of pulsatile flow is remarkably higher than that of the pulseless flow. The difference between the transfer capabilities of the two flow regimes was found to be more than 100 percent.
