Special Issue Information

Dear Colleagues,

Membrane technology plays a crucial role in both desalination and wastewater treatment processes. Membrane processes rely on a selective permeable barrier to separate dissolved or suspended substances from wastewater. There are several types of membranes used in these applications, including reverse osmosis membranes, nanofiltration membranes, ultrafiltration membranes, microfiltration membranes, distillation membranes, and ion exchange membranes, among others. Physical, chemical, and biological methods are involved in wastewater treatment with desalination functions.

This Special Issue welcomes original research papers, reviews, and tutorials on all aspects of the relationship between desalination and wastewater treatment. Innovative advancements that upgrade lab-based discovery to field-based applications will be of particular interest. Papers containing engineering principles that are integrated with knowledge from other disciplines are also welcome. Environmental materials and technologies are used for monitoring, sensing, and assessing environmental contaminants, and cleaner sustainable processes are encouraged.

This experimental study explores the mitigation of membrane fouling in membrane bioreactors (MBRs) through the combined use of granular activated carbon (GAC) and powdered activated carbon (PAC). The research assesses the impact of these materials on the fouling resistance, critical flux, and permeate quality using various mixed liquor suspended solids concentrations and carbon dosages. The results indicate that the GAC-PAC combination significantly reduces the total filtration resistance, particularly the cake layer resistance, by 11.7% to 13.6% compared to setups without activated carbon or with the individual carbon types. The study also reveals that this combination decreased the fouling rate by 15% to 24% at critical flux steps, demonstrating substantial improvements in fouling mitigation and operational efficiency. Furthermore, the GAC-PAC combination, which produces an adsorption process, enhances the permeate quality, achieving the near-complete removal of organic matter, total nitrogen, and turbidity, with total phosphorus removal reaching 99%. These findings demonstrate that the combined use of GAC and PAC not only reduces membrane fouling but also improves the overall MBR performance, making it a viable strategy for enhancing the efficiency of wastewater treatment processes.

Membrane-based persulfate catalysis technology offers a dual approach to wastewater treatment by facilitating both physical separation and chemical oxidation. This innovative method significantly enhances pollutant removal efficiency while mitigating membrane fouling, positioning it as a promising advanced oxidation technology for wastewater management. This review comprehensively examines the critical aspects of material design, activation mechanisms, and technological challenges. Membrane materials and structures are crucial for enhancing the overall efficiency of the technology. By analyzing various catalytic materials and modification strategies, the study reveals the intricate interactions between membrane structures, catalytic performance, and pollutant degradation. The clear mechanism of pollutant degradation is the key to achieve accurate degradation. The research highlights three primary activation pathways: free radical, non-radical, and hybrid mechanisms, each offering unique advantages in addressing complex water contamination. Finally, the future challenges and research directions are put forward. Despite remarkable progress, challenges remain in membrane stability, economic feasibility, and large-scale implementation. Therefore, this study outlines the latest materials, mechanisms, and prospects of membrane-based persulfate technology, which are expected to promote its widespread application in environmental governance.
