An Experimental Investigation of Humidity Effect on fabrication of Green Ceramic Membrane Prepared Via Dry Phase Inversion

Abstract

Ceramic membranes are gaining a market demand nowadays due to its characterization and performance. However, in the preparation of ceramic membrane for water and wastewater separation, the processes involved are taking a higher cost. In this work, ceramic membranes were prepared via phase inversion within controlled humidity by using different composition of low cost and green ceramic material, kaolin. The preparation of ceramic membranes was conducted via phase inversion in high humidity; i) 3°C and, ii) room temperature. In this paper, we report on the high humidity affected the viscosity of membrane suspension. Thus, the viscosity of ceramic suspension was giving integration towards membrane characterization and performance. A dense membrane structure was observed when the ceramic membranes were prepared in high humidity and kaolin composition. The morphology of overall, porous and dense structure of ceramic membranes was characterized by field emission scanning electron microscope (FESEM) at x50, x500 and x5000 magnification respectively.
