Integrated Submerged Membrane Bioreactor Anaerobic/Aerobic (ISMBR-A/O) for Nitrogen and Phosphorus Removal During Oil Refinery Wastewater Treatment

A review on novel and hybrid/integrated reactor configurations for the removal of recalcitrant organics from petroleum refinery wastewater

“…This method helped to achieve high removal efficiency of COD, total organic carbon (TOC), and toxicity with the values 45.5%, 43.3%, and 67.2%, respectively (Wei et al., 2010). Another study reported treatment of refinery wastewater by electrochemical oxidation treatment process using boron‐doped anode and ruthenium mixed oxide (Ru‐MMO) electrode, which resulted in 99.53% and 75.78% removal of phenol and COD respectively, at 5 mA/cm 2 of current density (Yavuz et al., 2010). However, this method requires a large amount of electricity, thus making it an expensive process (Feng et al., 2003).…”

“…The membrane filtration was carried out with 13 min on/2 min off, and the removal of COD, total phosphorus (TP), total suspended solids (TSS), suspended solids (SS), and phenol, BOD 5 , NH 3 ‐N, oil, and turbidity were 92%, 93.7%, 75.3%, 94.6%, 98.5%, 97.9%, 93.8%, and 99.9%, respectively. Integrated submerged membrane bioreactor, both anaerobic/aerobic conditions, has been studied for achieving a very high removal of COD, BOD, nitrogen, and phosphorus (Zhidong, 2010). In another study, an Integrated Submerged Membrane Bioreactor Anaerobic/Aerobic (ISMBR‐A/O) system with an airflow rate of 42 L/h, and 13 min on/4 min off mode was found to achieve overall COD and BOD removal of 91% and 90%, respectively.…”

“…Thus the discharge of refinery wastewater directly into the water body without proper treatment causes environmental pollution (Jafarinejad & Jiang, 2019; Zhao et al., 2014). To minimize the environmental impact of discharging untreated raw refinery wastewater into the environment, existing methods to treat the wastewater include photo‐degradation, Fenton and photo‐Fenton process, coagulation (El‐Naas et al., 2009), adsorption, chemical oxidation, electrochemical flocculation treatment (Diya'Uddeen et al., 2011; Yavuz et al., 2010). Among these methods, advanced oxidation processes (AOPs) such as those based on UV treatment and ozonation are common.…”
