| Abstract: | Industrialized multichannel ceramic ultrafiltration membranes were investigated in the paper. By liquid-liquid displacement method the pore size and pore size distribution were measured with the system of isobutanol-distilled water. Two tests were run, using the same membrane and system. The rejection rate was measured and compared with the pore size and pore size distribution. Operative conditions which can influence the rejection rate were discussed. The results will guide preparation and selection of industrialized ceramic ultrafiltration membranes. |
