Résumé :

The ceramic products are extremely interesting in the field of the membrane supports because of their mechanical resistance, chemical inertia, long working life and thermal stability. Research is currently directed towards the exploitation of materials at a lower cost. The purpose of this work is the development of microporous ceramic materials based on clay for liquid waste processing. Tests of filtration of saccharose solutions (10−2 M), sodium chloride (10−2 M) and Evans blue solutions (10−4 M) were performed on membane supports, which were synthesized starting from a natural local barbotine consisting of clay (21%), various kaoline kinds (35%), feldspath (20%) and finally sand (24%). Four different tubular membrane supports were prepared by mixing barbotine with activated carbon (1%), then barbotine with alumina-γ (3%) and finally with oxide titanium “anatase variety” (3%). The supports were thermally …
