Evaluation of Contaminated Water Treatment on the Durability of Steel Piles

The most common effluent created by the oil industry is oily wastewater. This produced water (PW) corrodes the steel piles in the infrastructure of bridges, which shortens their service life. 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 (TiO₂) with photo presence as an energy source. The results were organic elimination of 96.4% and 93.4% using ZnO and TiO₂, respectively. The 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. The results of the study demonstrated that the organic adsorption on a catalyst agent reinforced in nonappearance of radiation photo is insignificant.
