The demand of silicon carbide (SiC) membranes is growing for gas separation, aerosol filtration, and liquid separation processes due to its excellent properties including high hardness and strength, chemical and thermal stability, high melting point, oxidation resistance, high erosion resistance, etc. A deep understanding of the properties and performance of silicon carbide membranes is highly essential to shift the membrane market demands from polymeric and ceramic oxide to silicon carbide. The fabrication cost of the SiC membrane is of big concern to mitigate the industrial demand. The oxidation bonding process is considered as cost-effective method as it is possible to prepare SiC ceramics at low processing temperature, short sintering time, and is suitable for the preparation of large-size and complex-shaped components. Compared to other methods, oxide bonded porous SiC retains its strength up to very high temperatures and has excellent thermal stability. This book chapter is focused on the latest advancements of oxide bonded SiC support, layered SiC membranes, and their applications in water and oily wastewater treatment. Future challenges are highlighted toward further research endeavor.
