Utilization of Natural Zeolite for Development of Ceramic/Polymer Composite Membrane for Ultrafiltration

Abstract

Abstract Natural zeolites are aluminosilicate materials with tetrahedral structure. Natural zeolites have several advantages for many purposes such as adsorbent, catalyst support and ceramic membrane. This research explored the utilization of natural zeolite for the ceramic/polymer composite membrane. The results of the research show that membrane has the density of 1.64 gr/cm3 and porosity of 37.39% at the concentration of PVA of 7%. The performance test shows that composite membrane can be used for methylene blue separation and can be categorized as ultrafiltration. The coefficient of rejection that can be achieved is 93.53%. The membrane still has still a weakness. The flux of the membrane is very low.
