It is important to remove organic content in PW to prevent this outcome. Samples from the Ahdab oil field were used in this study. Two catalysts were selected: zinc oxide (ZnO) and titanium dioxide (TiO 2 ) with photo presence as an energy source. e results were organic elimination of 96.4% and 93.4% using ZnO and TiO 2 , respectively. e experimental conditions were pH � 3 and an irradiation time of 120 min. Due to the ability of ZnO to adsorb high amounts of organic content from PW, there was an increased elimination of organic content. Hence, the maintenance of steel piles durability is a good alternative to approach the goals of this study. e results of the study demonstrated that the organic adsorption on a catalyst agent reinforced in nonappearance of radiation photo is insignificant. 1.Introduction e major environmental and economic problem caused by oil and gas manufacturing factories is the production of oily wastewater [1, 2]. Usually, the wastewater produced is more than the treated crude oil volume, within 0.4–1.6 folds [3, 4]. e produced water (PW) must be treated properly before being released to reservoirs to avoid damaging the envi- ronment. Properly treated water can be used for other purposes and reduce water flooding [5, 6]. e significant quantities of polluted PW that are regularly released into the environment make the treatment methods of great impor- tance, requiring suitable treatments that can remove con- taminants that are present in many of these manufacturing streams. ese streams are problematic because of the high concentrations of organic content in PW [7]. Furthermore, there are stringent environmental rules that govern how PW is sent into tanks [8]. Some of the chemical compounds released due to human activities are difficult to remove through PW treatments and are eventually deposited in the environment [9, 10]. Many researchers raise concerns about PW treatment meeting environmental rules and being reused and recycled when possible [7, 11]. Numerous diverse methods exist for oil-water emulsions separation, such as adsorption [12, 13], ultrafiltration [14], biological processes [15, 16], and chemical coagulation [17, 18]. However, these techniques do have some limitations and drawbacks. For example, activated carbon adsorption can change the phase of contaminants without eliminating them, leading to additional contamination problems. In biological treatment processes, there are likewise many disadvantages including slow reaction rates, activated sludge disposal, and temperature control [19]. None of these treatment approaches are sufficient to reduce the most tenacious soil contaminants to satisfactory levels. Contaminated water reduces the service life of steel piles due to the interaction of some compounds with steel that leads to erosion of steel sections. Resultantly, steel piles can be corroded so extensively that the bridge life is signifi- cantly affected, as shown in Figure 1 [20].
