| Summary: | The discharge of oily wastewater and offshore oil spills contaminates the biotic and
aquatic environment and ultimately result in the destruction of the ecosystem. Recently,
the application of ceramic membranes has gained prodigious attention due to its efficiency
in oil-water separation process. Ceramic membranes developed from inorganic materials
are considered as the most promising technology for the treatment of industrial wastewater. Besides, different types superhydrophobic-superoleophilic substrates are being
developed using various substrate materials to tailor its purpose for higher efficiency.
Nonetheless, fouling and clogging phenomena restrict the performance of ceramic membrane in oil-water separation. This review emphasizes the recent innovation on superhydrophobic methods for the modification of ceramic membranes for oil-water recovery. It
comprises of an overview of the preparation technique of ceramic membrane using various
techniques. Moreover, the different types of hydrophobic ceramic membrane modification
using chemical agents and consequent effects on oil-water separation were discussed in
detail. Furthermore, the technical challenges and issues associated with the applications of
superhydrophobic-superoleophilic ceramic membrane for oil-water separation were discussed. Finally, future direction in the research of cost-efficient approach to produce
superhydrophobic ceramic membranes for oil-water filtration process is enumerated. |
