Special Issue Information

Dear Colleagues,

With the rapid development of global industry, the environmental pollution caused by wastewater discharge has raised extensive concerns. Moreover, increasingly strict discharge standards have prompted the research and development of novel wastewater treatment technologies. Meanwhile, concerning the severe issue of freshwater resource shortages, while dealing with sewage, water recovery has also become a new demand for wastewater-treatment technology. To meet this challenge, traditional centralized water treatment systems are in urgent requirement of transformation. As an alternative to traditional wastewater-treatment methods, membrane-based wastewater treatment processes have attracted much attention due to their inherent simplicity, scalable modular design, easy maintenance, and excellent separation efficiency. In recent years, membrane distillation technology has been widely explored in wastewater treatment, such as dyeing wastewater treatment, oil–water separation, and recovery of valuable components in wastewater, seawater, and brine. Compared with other membrane-based treatment methods, thermally driven membrane distillation exhibits extremely high pollutant removal rates.

In this regard, the present Special Issue will aim to provide a platform for researchers to exchange their novel ideas and share research outcomes related to membrane distillation and other suitable wastewater treatment technologies.

Topics of potential relevance to this Special Issue include (but are not limited to) the following:

  • Membrane distillation;
  • Pervaporation;
  • Membrane-based processes;
  • Advanced physicochemical and biological processes;
  • Industrial wastewater treatment;
  • Advanced desalination system ;
  • Oil–water separation;
  • Micropollutants removal;
  • Landfill leachate treatment;
  • Carbon footprint.

Authors are invited to submit their latest original results as full papers or short communications. Review articles, case-studies and perspectives are also welcomed.

We look forward to receiving your contributions.

Forward osmosis (FO), a green and economical membrane technology driven by a natural concentration gradient, has attracted increasing attention for wastewater treatment because it consumes less energy and removes large amounts of pollutants. In this research, an approach based on an FO mechanism that could improve the concentration of organic pollutants in wastewater collected from grass carp ponds was proposed. The wastewater serving as a feed solution (FS) was concentrated by FO, and sucrose was used as a draw solution (DS). The multiple chemical oxygen demand (COD) variation, the water flux, and the reverse solute flux during the FO process were investigated. The results indicated that the water flux and the reverse solute flux had similar trends in the processing of batch experiments 1–8, and the concentrating multiple of organic contaminants reached a maximum of 3.5 in the whole study. In addition, membrane fouling was studied via a scanning electron microscope (SEM), and a loose cake layer was deposited on the membrane surface. Moreover, findings from energy dispersive scanning (EDS) analysis showed that the fouling substances in the support layer of the membrane were mainly organic compounds and silica. In contrast, the dominant contaminants of the active layer contained several microelements (such as K and Ca) in addition to organic compounds. Three-dimensional (3D) fluorescence analysis confirmed that the FS components could enter the DS and the chemical components of the sucrose solution could also enter the FS. The findings of this study provide a new view on selecting a DS and protecting the aquaculture environment. Full article

Oil leakage and organic solvent industrial accidents harm the ecosystem, especially aquatic and marine life. Oil–water separation is required to combat this issue, which substantially enhances the ecosystem and recovery of oils from water bodies. In this aspect, significant efforts have been made by scientists to develop newer composite materials that efficiently separate oils from water bodies with exceptional recyclability. Membrane filtration is an efficient option for oil–water separation due to its ability to separate oil from water without involving any chemicals. However, relatively less water permeability and a high degree of surface fouling limit their applicability. The advent of two-dimensional nanomaterials (2D-NMs) gives newer insight in developing membranes due to their exceptional characteristics like hydrophobicity/hydrophilicity, selectivity, antifouling ability, flexibility, and stability. Incorporating 2D-NMs within the polymeric membranes makes them exceptional candidates for removing oil from water. Moreover, 2D-NMs offer rapid sorption/desorption rates and boost water transportation. Additionally, 2D-NMs provide roughness that significantly enhances the fouling resistance in the polymeric membrane. This review focuses on properties of 2D-NM-based polymeric membrane and their roles in oil–water separation. We also discussed strategies to improve the oil–water separation efficiency. Finally, we discussed oil–water separation’s outlook and prospects using 2D-NM-based polymeric membranes. This review might provide new insight to the researchers who work on oil–water separation.

Halogen-containing organic substances have a detrimental and toxic impact on the environment and human health due to their high stability, carcinogenic effects, and ability to accumulate when ingested. The production and release of these substances have significantly increased in recent decades, resulting in a lack of effective treatment technologies. Adsorbable organic halogens (AOX), a specific parameter used to monitor pollution, represents the total amount of chlorinated, brominated, and iodinated organics that can be adsorbed on activated carbon from various environments. This paper provides an overview of selected articles from the past three decades (1990–2023) focusing on the primary natural and industrial sources of AOX. It also evaluates different determination techniques and a variety of removal approaches based on biological, physical, chemical, and combined processes. Additionally, the limitations and efficiency of these approaches are briefly characterized. While biochemical and physical methods have been limited by financial constraints and reduced efficiency, biological, chemical, and physicochemical techniques have shown significant potential in improving water quality. This knowledge can be valuable for the development of alternative water treatment techniques and underscores the importance of sustainable water usage. Full article
