Large volumes of oily wastewater are generated by various industries, such as oil and gas, food, and metal processing. In particular, because of a massive generation of produced water from oil wells, the management of produced water has become an urgent problem. Nowadays, more attention has been focused on the use of ceramic membranes for the removal of stable emulsions from oily wastewater. In this paper, we briefly focus on the produced and refinery wastewater treatment by ceramic microfiltration (MF) and ultrafiltration (UF) membranes, followed by focusing on the fouling during filtration of oil–water emulsions. The fouling mechanism which explains the effect of membrane pore size and surface charges is described. Finally, the development of novel ceramic–based membranes for oily wastewater treatment will be overviewed.
