| ABSTRACT |
|
Ceramic membranes have limited applications owing to their high manufacturing cost, despite their advantages such as high mechanical strength, long-term durability, chemical resistance, and thermal resistance compared with polymeric membranes. However, they are known to have a similar life cycle cost (LCC) because their maintenance costs are lower than those of polymeric membranes. The permeability and separation effi ciency of ceramic membranes have rapidly increased, and manufacturing costs have continuously decreased due to continual research. Therefore, ceramic membranes have become increasingly competitive. In this review, we discuss the studies that focused on improving the permeability and antifouling properties of ceramic membranes by controlling their microstructure and surface characteristics, and we discuss the trends in materials and manufacturing process development to lower manufacturing costs. In addition, we introduce applications related to water and wastewater treatment to which ceramic membranes can be applied. |
