“…Da Rocha et al, (2013) showed that polycyclic aromatic hydrocarbons and aromaticity removal of approximately 92.7 and 96.2%, respectively, from petroleum-extraction wastewater were obtained by a solar photo-Fenton like process after 420 min and solar photo-Fenton process achieved 53% COD removal. Tony et al, (2012) obtained 50% COD removal after using (H2O2/ Fe +2 /UV) method under optimal conditions; pH 3, H2O2/Fe +2 ratio 10 while the current study revealed that the solar photo-Fenton process in an AOP was more efficient in the petroleum wastewater treatment, achieving a 74.7% COD removal at conditions; pH 3.68, H2O2/ Fe +2 ratio 14.…”

The aim of this study is to investigate the performance of solar photo-Fenton process (H2O2/Fe 2+ /Solar) to treat petroleum wastewater from Sohar oil Refinery, Oman. The effect of operating conditions such as pH, reaction time, Fenton ratio, and Fenton reagent concentrations are investigated. The obtained optimum conditions include), pH (3) and reaction time (180 min). TOC and COD removal rates are 64 % and 78 %, respectively. However, the photolytic process was less efficient in the petroleum wastewater treatment, achieving an 11.5% and 9% of COD and TOC removals, respectively. The solar photo-Fenton process has well efficient for petroleum wastewater treatment in the acidic conditions and more economic by free energy.

“…Many organic contaminants absorb UV energy in the range of 200-300 nm and decompose due to direct photolysis or become excited and more reactive with chemical oxidants like hydrogen peroxide and ozone. Ozone readily absorbs UV radiation at 254 nm wavelength producing H 2 O 2 as an intermediate, which then decomposes to Å OH (Reactions (6) and (7)) [2,17].…”

A B S T R A C TWastewater treatment for water reuse is one of the main concerns in oil refineries since it can lead to high economic and environmental benefits. This paper deals with treatment of an effluents of Shiraz oil refinery called Slops reservoirs effluent by means of ozone as an advanced oxidation agent. For this purpose, ozone is well dispersed at a dose of 5 g/h and effective transferred concentration of 2335 mg/L using a gas distributor into a semi-batch reactor containing 1 L of the wastewater. In order to determine the efficiency of the treatment, the removal percentage of COD and sulfide was selected as studying parameters. The effects of initial sulfide and COD concentrations, presence of UV light, initial pH, and temperature were investigated on the studying parameters. According to the obtained results, the highest removal rate occurred during the first 30 min reaction time. Also it has been observed that, for the initial sulfide concentration of 350 mg/L and the initial COD concentration of 975 mg/L, the ozonation process after 45 min resulted in 100% sulfide removal under optimum initial pH of 9.4 and optimum temperature of 15˚C and presence of UV light. While at the same conditions, 92% of COD removal has been achieved for 60 min ozonation. Also, water turbidity level significantly reduced during the treatment.

“…Davarnejad et al (2015) showed that maximum COD removal was around 82.55% at H2O2/PRW (Ratio of a mole of H2O2 per petroleum refinery wastewater volume) of 0.04, H2O2/Fe 2+ molar ratio of 2.75, pH of 3.5 and reaction time of 90 min. Da Rocha et al, (2013) showed that the 53% COD removal was achieved by the solar photo-Fenton process from petroleum wastewater.…”

The objective of this study is to summarize studies and investigations about advanced oxidation processes (AOPs) used for the treatment of petroleum wastewater, which mainly contained oil, organic matter and other compounds. The big difference was shown in the specification of wastewater among the investigated studies and a wide variety of pollutants at varying concentrations. The most compounds in petroleum wastewater were the mixture of hydrocarbons and inorganic compounds. Advanced oxidation processes (AOPs) have a capability of rapid degradation of recalcitrant pollutants in the aquatic environment. However, the literature regarding petroleum wastewater treatment is very little and advanced oxidation processes (AOPs) are still not being used on an industrial scale in oil refineries. Most studies were focused on the degradation of some pollutants found in the petroleum wastewater such as sulphides, ammonia, phenols and organic materials. This review focused on works that investigated advanced oxidation processes (AOPs) by monitoring general petroleum wastewater parameters such as TOC, COD, BOD, oil, and phenols. It presented an overview of photocatalytic degradation of pollutants in petroleum wastewater and highlighted the basics of these processes including the optimum parameters.
