“…One of the major disadvantages of this technique for practical application is associated with galvanic corrosion of iron, which leads to reduction of iron reactivity and easy plugging of the system due to accumulation of corrosion product [187]. He et al [188] combined microelectrolysis with microwave coagulation technology to treat heavy oil wastewater, and this combination was found to reduce corrosion rate by 96.5%. Instantaneously the oil and suspended solids (SS) removal rates of 95.5 and 98.3% were recorded.…”

Industrial developments in the oil and gas, petrochemical, pharmaceutical and food sector have contributed to the large production of oily wastewater worldwide. Oily wastewater pollution affects drinking water and groundwater resources, endangers aquatic life and human health, causes atmospheric pollution, and affects crop production. Several traditional and conventional methods were widely reported, and the advantages and limitations were discussed. However, with the technology innovation, new trends of coupling between techniques, use of new materials, optimization of the cleaning process, and multiphysical approach present new paths for improvement. Despite these trends of improvement and the encouraging laboratory results of modern and green methods, many challenges remain to be raised, particularly the commercialization and the global aspect of these solutions and the reliability to reduce the system’s maintenance and operational cost. In this review, the well-known oily wastewater cleaning methods and approaches are being highlighted, and the obstacles faced in the practical use of these technologies are discussed. A critical review on the technologies and future direction as the road to commercialization is also presented to persevere water resources for the benefit of mankind and all living things.
