“…Membrane hydrophobicity and low porosity reduce the water flux in the MD process. The major challenge associated with the MD membrane is pore wettability, affecting the membrane stability and hydrophobicity and, thus, affecting membrane performance [50]. The MD membranes should have high permeability, high hydrophobicity, low pore wettability, and high salt rejection.…”

In the past few decades, the role of nanotechnology has expanded into environmental remediation applications. In this regard, nanofibers have been reported for various applications in water treatment and air filtration. Nanofibers are fibers of polymeric origin with diameters in the nanometer to submicron range. Electrospinning has been the most widely used method to synthesize nanofibers with tunable properties such as high specific surface area, uniform pore size, and controlled hydrophobicity. These properties of nanofibers make them highly sought after as adsorbents, photocatalysts, electrode materials, and membranes. In this review article, a basic description of the electrospinning process is presented. Subsequently, the role of different operating parameters in the electrospinning process and precursor polymeric solution is reviewed with respect to their influence on nanofiber properties. Three key areas of nanofiber application for water treatment (desalination, heavy-metal removal, and contaminant of emerging concern (CEC) remediation) are explored. The latest research in these areas is critically reviewed. Nanofibers have shown promising results in the case of membrane distillation, reverse osmosis, and forward osmosis applications. For heavy-metal removal, nanofibers have been able to remove trace heavy metals due to the convenient incorporation of specific functional groups that show a high affinity for the target heavy metals. In the case of CECs, nanofibers have been utilized not only as adsorbents but also as materials to localize and immobilize the trace contaminants, making further degradation by photocatalytic and electrochemical processes more efficient. The key issues with nanofiber application in water treatment include the lack of studies that explore the role of the background water matrix in impacting the contaminant removal performance, regeneration, and recyclability of nanofibers. Furthermore, the end-of-life disposal of nanofibers needs to be explored. The availability of more such studies will facilitate the adoption of nanofibers for water treatment applications.

“…The coupled PEC and O-3 system performed well in reducing color, turbidity, inorganic carbon, and COD. Fenton oxidation was deployed as a feed pretreatment prior to membrane distillation to design a compact system for produced water management (Ricceri et al, 2019). The combined scheme demonstrated some advantages with limitations.…”

Petrochemical wastewater and produced water from oil and gas operations typically contain an array of organic and inorganic contaminants. The complexity of the wastewater, stringent environmental regulations, and the need for sustainable solutions have driven many research efforts in studying and developing advanced technology or combined treatment processes. On the other hand, the wastewater itself can be resources for water, energy, and other valuable product if appropriate technology is developed to recover them in a cost-effective fashion. The research advances in wastewater treatment and resource recovery technology are reviewed and summarized. For petrochemical wastewater, progresses were made in advanced oxidation, biological processes, and recovery of energy and water from wastewater. For produced water, many efforts were focused on membrane processes, combined systems, and biological treatment.

The purpose of this study is to establish a model to analyze and compare different types of pre-oxidation technologies in shale gas backflow, so as to guide actual production. With the progress of membrane-based processes, membrane separation technique shows great potential in shale gas flowback and produced water (SGFPW) reuse. But membrane fouling due to high concentration of organic matter is still a big problem. Therefore, using integrated process, which combines pre-oxidation with membrane separation, is a good way to deal with membrane fouling. However, there are various kinds of oxidation technologies that can be used into shale gas wastewater treatment, meaning that there needs to be a scheme to guide which technology can do best in different situations. In this paper, the output-output model is used to analyze the pre-oxidation technology. The current pre-oxidation technology is divided into two types, among which the most representative ozonation and Fenton oxidation are selected as examples, and the capital investment in this link is taken as the index for analysis. It is concluded that Fenton oxidation method can be used when the amount of waste water is small, but when the amount of waste water is large, the economic benefit of ozonation is higher. Similarly, this model can be widely applied to the analysis and comparison of a large number of pre-oxidation technologies in shale gas wastewater, and can also be modified as the technology advances.
