Abstract

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.
