Special Issue Information

Dear Colleagues,

With the rapid development of industries, organic pollutants are being increasingly released into the environment. The presence of recalcitrant and emerging micropollutants in the environment (e.g., pharmaceuticals, personal care products, etc.) has potential negative impacts on human health and ecosystems. Therefore, wastewater treatment plays an important role. Among them, membrane-based technologies are recently being considered as effective methods for conventional water and wastewater remediation processes to achieve the increasing demands for clean water and to minimize the negative environmental effects. With the potential to bridge economic and sustainability gaps, membrane technology has reached the point where treated wastewater can be successfully reused for industrial, agricultural, and domestic purposes and offers many perspectives in wastewater treatment processes.

This Special Issue invites original research papers and reviews on the removal of pollutants from wastewater, involving novel methods and new materials in various aspects of wastewater treatment, with a special focus on wastewater treatment utilizing membrane technology.

Subject areas may include, but are not limited to, the following:

  • Membrane process;
  • Advanced membrane separation;
  • Ionic resource recovery;
  • Ammonia nitrogen removal;
  • Electro-driven membrane;
  • Production of by-products during wastewater treatment;
  • Removal of refractory organic pollutants in water;
  • Other water treatment technologies, such as advanced oxidation processes, photocatalysis, electrocatalysis, and electrodialysis.

In this study, a novel method for the high-performance treatment of oily wastewater was introduced using a tungsten (VI) oxide (WO3)/MXene composite membrane based on poly (arylene ether sulfone) (PAES). Composite membranes were fabricated with superhydrophilic (SH) and superoleophobic (SO) characteristics, which allow for the high-performance treatment of oily wastewater. The fabricated composite membrane can also photodegrade organic types of pollutants with just a short period of UV, enabling self-cleaning and anti-fouling properties. Moreover, the comprehensive characterization of the composite membrane through FTIR, SEM, and XRD analyses yielded valuable insights. The FTIR analysis revealed the characteristic peaks of WO3, MXene, PAES, and the synthesized composite membrane, providing essential information on the chemical composition and properties of the materials. The XRD results demonstrated the crystal structures of WO3, MXene, PAES, and the synthesized composite membrane, further enhancing our understanding of the composite membrane. Additionally, the SEM images illustrated the surface and cross-section of the fabricated membranes, highlighting the differences in pore size and porosity between the PAES membrane and the WO3–MXene composite membrane, which directly impact permeate flux. The study showed that the composite membrane had a remarkable recovery time of only 0.25 h, and the efficiency of the separation process and water flux recovered to 99.98% and 6.4 L/m2.h, respectively. The joint influence of WO3 and MXene on composite membranes degraded contaminants into non-polluting substances after sunlight irradiation. This process effectively solves the treatment performance and decrease in permeate flux caused by contamination. The technology is membrane-based filtration, which is a simple and advanced method for treating polluted water. This innovative work offers promising solutions to address water pollution challenges and holds potential for practical applications from a self-cleaning and anti-fouling point of view. Full article
