Abstract

The fabrication of low cost ceramic membranes for microfiltration were studied by using a natural materials (shirasu balloon) which are produced from glassy volcanic materials. The shirasu powder was formed into cylindrical shaped membranes and sintered at five different temperatures from 600 °C to 800 °C using spark plasma sintering (SPS). The porosity and density of membranes were measured according to Archimedes method. The effect of sintering temperatures on microstructure and phase of the membranes has been investigated using FESEM and XRD. A filtration experiment was carried out to study the membrane performance for waste water filtration. The quality of the filtered water was determined by analyse the pH, turbidity, suspended solid, chemical oxygen demand (COD) and biochemical oxygen demand (BOD5). The porosity reduced from 48.9% to 40.32% while the membrane density increased from 1.15 g/cm3 to 1.33 g/cm3 with increasing sintering temperatures from 600 °C to 800 °C. A little shrinkage occur during spark plasma sintering process. From the FESEM microstrcture, the maximum pore size of the membrane that has been observed at 600 °C is about 4.7 µm. Shirasu membrane are able to produce clean and clear treated water during the microfiltration test with membrane sintered at 800 °C and there is an improvement in quality of water that has been filtered. The ceramic water filter was successfully produced without the involvement of the high-tech, sophisticated machines and methods as well as complex materials
Shirasu球囊制备废水过滤陶瓷膜的研究
研究了以玻璃状火山材料为原料制备低成本陶瓷微滤膜的方法。采用火花等离子烧结技术(SPS)在600 ~ 800℃的5种不同温度下烧结白须粉。采用阿基米德法测定膜的孔隙率和密度。利用FESEM和XRD研究了烧结温度对膜的微观结构和物相的影响。通过过滤实验研究了膜对废水的过滤性能。通过对过滤水的pH、浊度、悬浮物、化学需氧量(COD)和生化需氧量(BOD5)的分析来确定过滤水的质量。随着烧结温度从600℃升高到800℃,孔隙率从48.9%降低到40.32%,膜密度从1.15 g/cm3提高到1.33 g/cm3。在放电等离子烧结过程中会产生少量的收缩。从FESEM微观结构来看,在600℃时观察到的膜的最大孔径约为4.7µm。白松膜在800°C烧结膜的微滤试验中,能够生产出干净、清澈的处理过的水,过滤后的水质有了改善。陶瓷滤水器的成功生产没有涉及高科技,复杂的机器和方法,以及复杂的材料
