“…There are many ways to treat this type of water; for the separation of organic content from generated water, a variety of approaches are available, including coagulation (Jabbar and Alatabe, 2021; Hadi et al, 2020), adsorption , biological separation (Lekomtsev et al, 2021), and membrane separation (Shawkat et al, 2016). None of these treatment methods, however, adequately treats the produced water.…”

Produced water is one of the most dangerous types of pollution for the environment, specifically the soil, since it is full of oil, suspended particulates, dissolved compounds, and various other pollutants. This research describes the advanced oxidation process (AOPs) that were studied to purge the generated water from the Al Khabaz oilfield located in (Northern Iraq -Kirkuk governorate) of any oil content using two photocatalytic homogeneous and heterogeneous processes in the batch system under optimal conditions: homogeneous processes, including Photo-Fenton (hydrogen peroxide, ferrous sulfates, and ultraviolet light), and Fenton process (hydrogen peroxide, and ferrous sulfates), and Direct-Photolysis (ultraviolet only) were used studied the effects of hydrogen peroxide (H 2 O 2 ) & ferrous sulfate (Fe +2 ), doses, irradiation time, pH Value, and intensity of UV to the oil removal efficiency. This work investigated the maximum efficiency in Photo Fenton = 85.68%, in Fenton = 75.01%, and in direct UV photolysis = 56.64%. The heterogeneous photocatalytic process (TiO 2 /UV) studied the effect of titanium dioxide (TiO 2 ) nanoparticles doses and UV intensity. The results show that the optimal efficiency achieved was 60.95%. X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier Transforms Infrared Spectroscopy (FT-IR) were used to look into the characteristics of the catalyst titanium dioxide nanoparticles. TiO 2 NPs seemed to be spherical in the SEM test, and their FT-IR analysis absorption values ranged from 424.77 to 3403.71 cm -1 . Their sizes varied between 31.57 and 38.40 nm, and XRD revealed details regarding their chemical composition.

Produced water is naturally occurring water that is produced as a byproduct during the exploration and production of oil and natural gas from the subsurface system. Produced water brought to the surface contains high saline content and may also contain Naturally Occurring Radioactive Material (NORM). Therefore, the efficient treatment, use, and disposal of produced water remain a critical issue for the energy industry with environmental and human health implications. Over the years, researchers have presented numerous treatment technologies ranging from physical, chemical, and biological perspectives. Some industries have combined one or two of these methods to improve the treatment quality of produced water required for distinct purposes, and these practices have been extended to the energy industry. As the energy industry strives to sustain production capacities and maintain or increase profitability in this energy-transition era, water production is also rising while there is a reduction in its re-purposing and utilization for energy and environmental industries. Our study focuses on over 100 studies conducted over the past five decades. This study presents a comprehensive overview of the produced treatment methods, challenges regarding the execution and implementation of these methods in the energy industry. We highlight the important fundamental questions that are yet to be addressed and propose new directions for more environmentally friendly and economically viable solutions for the treatment and use of produced water.
