Abstract

Emphasizing upon the need to develop and target application within surface roughness of ceramic membrane, this work addresses the new method of „modified phase inversion‟. Phase inversion that commonly used in the fabrication of polymeric membrane was applied. The thermodynamic properties (composition and temperature) involved in the phase inversion system was studied. Knowledge of the surface roughness of ceramic membrane is very important towards it characterization and performance. In this study, the investigation towards the surface of ceramic membrane was characterized in term of surface roughness and morphology. Kaolin with 25μm was used as the composition of membrane preparation. The amounts of kaolin investigated were 60g, 70g and 80g respectively while the temperature was conducted assist room temperature and 3oC. Result of atomic force microscopy (AFM) showed that by decreasing phase inversion temperature improve the membrane surface roughness from 0.136 μm to 0.093 μm at 80g of kaolin content. Similar trend for the study towards the effect of kaolin composition. In addition, the SEM images explained that membrane surface morphology obviously change with the effect of temperature during phase inversion process. Experimental investigations inferred that te membrane performance is optimal for minimum combination of thermodynamic properties, temperature (room temperature) and kaolin composition (60g) at which conditions, PWF and mean pore radius were obtained as 80.1221 Lm-2h-1 and 0.112μm respectively. Membrane prepared at low temperature (3oC) possesses smallest pore size of 0.043μm under 80g of kaolin composition.
