“…The function of a coalescer is often influenced by the velocity of fluid, droplet diameter, pressure, interfacial curvature interfacial tension, etc. [167]. Coalescers usually used in the industry are particle bed coalescers and fiber bed coalescers and represent high productivity, accessible installation, simple operation, and bed cleaning.…”

The petroleum industry produces a large amount of wastewater, known as produced water (PW), during oil production and processing. This PW contains hazardous organic and inorganic components that can harm the environment. Conventional treatment methods have been used to purify PW, but they do not meet environmental regulations, especially when the goal is to reuse the water. Therefore, further research is needed to find an effective technology for managing PW. This review focuses on the characteristics and management of PW originating from oil and gas fields. Firstly, we provide a detailed overview of PW production scenarios worldwide and in the US with detailed quantities and chemical compositions of organic, inorganic, and physicochemical characteristics. Secondly, challenges and environmental concerns associated with treating PW are discussed. Thirdly, all relevant treatment technologies for PW are systematically explored. In addition, this review highlights the management of PW and suggests treatment options and best practices for the industry, and finally, future research needs and opportunities for sustainable water treatment and effective reuse technologies are addressed. Because PW contains a variety of severe contaminants, single methods have not been effective in converting it to a reusable form or fulfilling disposal criteria. As a result, integrated technologies may provide a potential approach that not only meets regulatory standards but also provides chances to employ PW as a non-conventional water supply. Advances in PW management are critical and demand a defined framework and risk-based approach to determine and build the most efficient plan.

“…However, the researchers noted that biological treatment is required to reduce the treatment cost and finalize the treatment process. Furthermore, da Silva Almeida et al [41] utilized a coalescence fibrous media for the separation of the emulsion oil from water. However, this process is not well understood and is often based on observation rather than experimental values [41].…”

Produced water (PW) is the most significant waste stream generated in the oil and gas industries. The generated PW has the potential to be a useful water source rather than waste. While a variety of technologies can be used for the treatment of PW for reuse, biological-based technologies are an effective and sustainable remediation method. Specifically, microalgae, which are a cost-effective and sustainable process that use nutrients to eliminate organic pollutants from PW during the bioremediation process. In these treatment processes, microalgae grow in PW free of charge, eliminate pollutants, and generate clean water that can be recycled and reused. This helps to reduce CO2 levels in the atmosphere while simultaneously producing biofuels, other useful chemicals, and added-value products. As such, this review focuses on PW generation in the oil and gas industry, PW characteristics, and examines the available technologies that can be used for PW remediation, with specific attention to algal-based technologies. In addition, the various aspects of algae growth and cultivation in PW, the effect of growth conditions, water quality parameters, and the corresponding treatment performance are presented. Lastly, this review emphasizes the bioremediation of PW using algae and highlights how to harvest algae that can be processed to generate biofuels for added-value products as a sustainable approach.

“…Coalescence separation technology has been widely used in the petrochemical industry to separate emulsions, providing guarantees for oil extraction, wastewater treatment, product purification and process equipment protection 1,2 . Benefiting from its simple structure, good environmental performance, and high separation efficiency, the fiber coalescence method, as a physical method, has received increasing research and attention in the separation of liquid–liquid heterogeneous systems 3 .…”

Cross fibers at different angles are essential for enhancing the separation of emulsions as the basic structure in fiber fillers. In this article, the retention and detachment process of droplets on fiber intersection were investigated using high‐speed camera technology to explore the critical volume, slip path and droplet oscillation. The results indicate that the critical volume retained on the intersection is significantly affected by the fiber slope, cross angle between fibers, and liquid viscosity. A droplet‐fiber interfacial force balance model is established to predict the critical volume and the tilt angle corresponding to maximum critical volume. The switching behaviors of selected fiber slippage depend on the slope, diameter, and affinity of the fiber. Compared with the lipophobic fiber woven mesh, the droplets on the lipophilic fiber mesh slip upward with a larger oscillate deformation and obvious periodicity. The mean deformation of droplets is 1.16 times that on lipophobic fiber.
