  • Which methods are used to treat oily wastewater?
  • Methods such as flotation, chemical coagulation, gravity separation and sedimentation are traditional approaches for the treatment of oily wastewater (Abuhasel et al. 2021 ).
  • What are the recent developments in oily wastewater treatment systems?
  • Recent development in oily wastewater treatment systems using demulsification methods from 2018 to present. Performance of biological treatments (BT) reported in the literature from 2018 to present. Research on material modification of polymeric membranes and their effects on oily wastewater cleaning from 2018 to present.
  • How effective is combined treatment for industrial oily wastewater?
  • Furthermore, the use of combined treatment processes is effective for the removal of hazardous pollutants present in high-strength oily wastewater. This review provides insights into advanced and emerging state-of-the-art technologies for safe and efficient treatment of industrial oily wastewater.
  • Can electrochemical technology be used to treat oily wastewater?
  • Electrochemical technology is a promising alternative for the treatment of oily wastewater containing organic pollutants by the application of electric current supplied to the electrodes (de Almeida et al. 2014; Treviño-Roséndez et al. 2021 ). It occurs as electrocoagulation (EC), electrofloatation (EF), etc. (Chen 2004 ).
