This study attempts to develop asymmetric ceramic membrane filter from nanosilica particles for ultrafiltration (UF) membrane. Alumina tubes were used as supports and these were coated with SiC to act as the intermediate layer. The UF membrane was developed using filtration technique through a chemical suspension of the particles. Nanosilica was suspended in HCl acid and was deposited on the alumina tube using a special coating assembly. The UF membrane was characterised for pore size, thickness, microstructure and topography. This study found that the use of nanoparticles for membrane development could easily control the pore size as well as the thickness of the membrane. The uniformity of the membrane thickness could also be achieved through this filtration technique.
