Abstract
Membrane technology has become a highly efficient separation technology for industrial applications over the past few decades. The key requirements for porous ceramic membranes are mechanical stability, controlled pore morphology, and high permeability. However, only a few studies have been conducted to optimise commercial membrane filters. In this study, a multichannel cylindrical-tube-type support with a microfiltration (MF) coating was prepared. To design a reliable porous structure and avoid shrinkage defects, the support layer was extruded using a combination of different-sized Al2O3 particles. The alumina microfiltration coating was developed using multiple dip-coatings to control the membrane thickness. An inorganic surface modification was conducted for the first time on an extruded membrane using a SiO2 sol-gel technique to enhance the antifouling properties. Furthermore, the membrane properties were investigated with scanning electron microscopy, mercury porosimetry, and a dead-end microfiltration system.
