Effects of Synthesis Parameters on Mullite Microfiltration Membranes: Structure and Performance

In this study, effects of calcination temperature, hydraulic pressure and alumina content on permeation flux and porosity of microfiltration (MF) membranes were evaluated. To complete mullite phase formation, α-alumina was added to kaolin. CMC (Carboxymethyl Cellulose) was also used to increase porosity and permeation flux of the membranes. Many experiments should be carried out to understand effects of different parameters. Logical selection of the experiments cansave time and money. To obtain the meaningful results, full factorial method was used. The MF membranes were successfully made of 40% alumina, at pressure of 300 bar and were calcined at temperature of 1150 °C. Water permeation flux and porosity of these membranes were evaluated as 58.3 kg/m2.h and 34.5%, respectively
