Summary
This Special Issue, "Advances in Material Processing and Fluid Transport for Circular Wastewater Systems," focuses on scientific and engineering advances that enable wastewater treatment systems to move beyond pollutant removal toward circular, resource-efficient operations. Emphasis is placed on the coupled roles of fluid transport phenomena and materials processing in improving treatment efficiency, process intensification, energy reduction, and resource recovery.
We welcome contributions that elucidate how flow behavior, mass and momentum transfer, and material functionality interact across treatment units, from reactors and separators to membranes and hybrid systems. Submissions may include fundamental studies, applied research, experimental investigations, numerical modeling, or theoretical analyses, with particular interest in approaches that advance sustainability in circular wastewater systems.
By showcasing scalable, innovative, and multidisciplinary solutions, this Special Issue aims to support the transition toward wastewater systems that maximize recovery of water, energy, and valuable materials while minimizing environmental impact, providing a platform for researchers and engineers to share novel strategies and validated methodologies for sustainable process design.
Topics of interest include (but are not limited to):
· Fluid transport, hydrodynamics, and mass transfer in wastewater treatment processes
· Materials processing for membranes, adsorbents, catalysts, and porous media
· Circular wastewater systems, resource recovery, and water reuse technologies
· Multiphase flow, mixing, and reactor design for sustainable treatment
· Modeling, simulation, and optimization of fluid–materials interactions in wastewater systems
