Study on oil/water separation using ceramic membrane before and after its wear and repair
Background
The amount of industrial and domestic wastewater being generated is continuously increasing with the rapid advancements in society and the economy. Oil/water separation is an important part of wastewater treatment, and the separation membrane plays a crucial role in this process. Ceramic separation membrane are widely used owing to their exceptional corrosion resistance and high-temperature resistance. However, the oil/water separation efficiency and flux are reduced after surface wear of the ceramic membrane.
Methods
In this study, the recovery in separation flux and efficiency after surface wear of a Silicon Carbide (SiC) ceramic membrane is studied.
Significant Findings
The flux of the ceramic membrane separation for n-hexane-in-water emulsion, cyclohexane-in-water emulsion, and petroleum ether-in-water emulsion was 417.20 ± 43.08, 503.18 ± 48.09, and 496.82 ± 29.19 L·m–2·h–1, respectively, and the separation efficiency was 97.62 ± 0.16 %, 97.38 ± 0.18 %, and 97.13 ± 0.12 %, respectively. After high-temperature sintering, the worn ceramic membrane formed a new microstructure, and the oil/water separation efficiency and flux increased by 6.66 % and 108.84 L·m–2·h–1, respectively. The present study establishes the fundamental basis for the practical implementation of ceramic membranes for oil/water separation.
期刊介绍：
Journal of the Taiwan Institute of Chemical Engineers (formerly known as Journal of the Chinese Institute of Chemical Engineers) publishes original works, from fundamental principles to practical applications, in the broad field of chemical engineering with special focus on three aspects: Chemical and Biomolecular Science and Technology, Energy and Environmental Science and Technology, and Materials Science and Technology. Authors should choose for their manuscript an appropriate aspect section and a few related classifications when submitting to the journal online.
