Membrane Separation Processes for Water Treatment

Dear Colleagues,

During the last decade, increasing population growth, rapid industrialization, urbanization, and the impacts of climate change have intensified global water scarcity and degradation of water resources. At present, there is a growing need for efficient, sustainable, and cost-effective technologies for the treatment, purification, and reuse of water and wastewater. Membrane separation processes have emerged as important technologies in this context because of their ability to provide high-quality treated water with relatively compact process configurations and opportunities for process integration. Advances in membrane materials, surface modification, membrane module design, and hybrid treatment systems have further expanded the potential applications of membrane technologies, including microfiltration, ultrafiltration, nanofiltration, reverse osmosis, forward osmosis, membrane distillation, and emerging membrane-based processes. Nevertheless, membrane fouling, concentration polarization, energy consumption, membrane degradation, selectivity, and the management of concentrated waste streams remain important challenges for large-scale and sustainable implementation.

This Special Issue aims to provide a comprehensive platform for researchers, engineers, and practitioners to present recent advances in membrane separation processes for water and wastewater treatment. Particular emphasis will be placed on innovative membrane materials and fabrication strategies, membrane surface modification, process optimization, fouling control, transport mechanisms, membrane characterization, and the integration of membrane processes with conventional and advanced treatment technologies. Contributions addressing the fundamental mechanisms, process modeling and simulation, techno-economic and environmental assessment, scale-up, pilot- and full-scale applications, and resource recovery are also encouraged. The Special Issue seeks to promote interdisciplinary research and provide new insights into the development of efficient, robust, sustainable, and economically viable membrane-based technologies for water treatment and reuse.

The topics of interest for publication include, but are not limited to, the following:

• Emerging membrane separation and membrane contactor technologies;
• Nanomaterials and advanced membrane materials for water treatment;
• Removal of emerging contaminants, pharmaceuticals, heavy metals, salts, nutrients, and microorganisms;
• Hybrid and integrated membrane treatment systems;
• Membrane bioreactors and membrane-based advanced oxidation processes;
• Membrane process modeling, simulation, and optimization;
• 3D printed membranes and their applications;
• Resource recovery and circular-economy approaches;
• Techno-economic analysis and life-cycle assessment of membrane processes;
• Pilot-scale and full-scale applications of membrane technologies.

Thank you for your consideration, and I sincerely hope you will consider contributing to this Special Issue.
