Abstract
The preparation and characterization of tubular ceramic membranes aiming to do microfiltration using alumina and kaolin powders as raw materials were carried out. The membranes were obtained by doing slip casting of the suspensions. The suspensions consisted of alumina-kaolin powders, water, and 0.9 wt.% of dolapix CE64 as deflocculant. The variations made during suspension preparation includes the use of different ratios between alumina-kaolin powder and distilled water of 60 wt.%: 40 wt.% and 65 wt.% : 35 wt.%, and also the use of addition of different percentage of starch of 0.5, 1, 2, and 3 wt.% as pore former into the suspension. Upon casting, the manufacture was then followed by sintering process in a furnace, which was also varied into up to 1000°C, 1100°C, and 1200°C. The procedure was then completed by doing subsequent characterizations of the sintered membranes by determining their microstructure using SEM (Scanning Electron Microscopy) and pure water permeability and E. coli bacteria rejection experiment with McFarland turbid solution that were executed in a customized microfiltration module. All of the membrane samples succeeded to have 100% E. coli rejection. However, out of all the membrane samples, membrane with powder to distilled water ratio of 65 wt.% : 35 wt.% with 0.9 wt.% dolapix sintered at 1100°C gave results to the highest water permeate flux.
