- Abstract
Macro-porous ceramic supports, with a zirconia top layer, for microfiltration (MF) membranes, were prepared from local low cost raw materials. For this, the extrusion method was used. The characterization of the raw materials and the study of the effect of the sintering temperature on the morphology, pore size distribution and the mechanical properties of supports were studied. For example, it was found that, the porosity and the average pore size for a tubular ceramic support fired at 1,350°C during 1 h are about 47% and 6.4 µm, respectively. The elaboration of the zirconia toplayer is performed by the slip casting method. This membrane can be used for MF; indeed, it showed a good rejection performance of methylene blue: 70%. It is also suitable for waste water treatment.
