송인혁 KIMS Ceramic membranes can be applied under extreme operating conditions such as low pH, high pressure and high temperature. Especially, the inherent limitations of conventional polymer membranes can be overcome by adopting ceramic membranes simply to the existing water treatment systems. Moreover, there are a lot of potential applications of ceramic membranes such as distillation, adsorption and extraction in various industrial areas. Therefore, the ceramic membrane technology is not a mere ceramic processing technology, but a highly influential technology to the overall environment technology. In this study, we focused the current status and prospects of ceramic membrane for water treatment by adopting various kinds of ceramic materials such as alumina, silicon carbide and natural materials. Especially, the ceramic membrane of flat-sheet type fabricated by extrusion process was introduced in various applications such as membrane bioreactor (MBR), industrial wastewater, and pretreatment in desalination. This presentation consists of three parts: (1) Tailoring pore structures of the substrate of ceramic membrane, (2) Functionalizing the coating layer of ceramic membrane, and (3) Extruding the substrate of ceramic membrane.
