New microfiltration membranes from Tunisian natural materials are obtained using ceramic method. Paste from Tunisian silty marls refereed (M 11 ) is extruded to elaborate a porous tubular configuration used as supports. The support heated at 1190°C, shows an average pore diameters and porosity of about 9.2μm and 49%, respectively. The properties in term of mechanical and corrosion resistances...
The development and the characterisation of new supports for microfiltration and ultrafiltration membranes from apatite applied to filtration are presented. The choice of this material is based primarily on its low cost (considering its abundance in the Tunisian ores).The support, with tubular configuration, was prepared from natural apatite: apatite powders were crushed for 30min and sieved to 200μm...
