  • How is wastewater treated in a refinery?
  • The treatment of produced water and refinery wastewater is traditionally carried out byphysical, chemical, and biological treatment processes. In recent years, it has been focused on the use of membrane technologies.
  • Are Advanced Filtration membranes suitable for oily wastewater treatment?
  • In this review, we concentrated on the recent development of advanced filtration membranes including polymer-dominated membranes, ceramic membranes and nanomaterial-based advanced membranes for oily wastewater treatment, especially the separation of an emulsified oil/water mixture.
  • Which membrane modules are used for oily wastewater treatment?
  • Cheryan [ 33] and Tanudjaja et al. [ 175] reported that spiral wound, tubular, and hollow fiber membrane modules are used for the purification of oily wastewater treatment.
  • Can ceramic filtration membranes be used for oily wastewater treatment?
  • Because of the limitation of their pore sizes, directly employing ceramic membranes for the separation of emulsified oil/water mixtures would cause severe fouling problem and low fluxes. 99, 104, 108 Among the various ceramic filtration membranes, zirconia ceramic membranes exhibit better performance than others for oily wastewater treatment.
