A Review on the Treatment of Petroleum Refinery Wastewater Using Advanced Oxidation Processes

The petroleum industry is one of the most rapidly developing industries and projected to grow faster in coming years. recent environmental activities global requirements for cleaner methods are pushing refining use green techniques industrial wastewater treatment. Petroleum contains a broad diversity contaminants such as hydrocarbons, oil grease, phenol, ammonia, sulfides, other organic composites, etc. All these compounds within discharged water from exist an extremely complicated form, which unsafe environment. Conventional treatment systems treating refinery have shown major drawbacks including low efficiency, high capital operating cost, sensitivity biodegradability toxicity. advanced oxidation process (AOP) method applied objective this work review current application AOP technologies wastewater. using includes Fenton photo-Fenton, H2O2/UV, photocatalysis, ozonation, biological processes. This reports that efficiencies strongly depend on chosen type, physical chemical properties target contaminants, conditions. It reported mechanisms, well hydroxyl radical oxidation, might occur throughout donate decrease contaminants. Mainly, advances discussed. Moreover, identifies scientific literature knowledge gaps, future research ways provided assess effects
