Special Issue Information

Dear Colleagues,

Recent advances in polymer adsorbents have significantly enhanced their potential for water treatment, especially in the areas of pollutant removal and environmental sustainability. Key developments include the creation of nanocomposite materials that improve adsorption efficiency, the use of biopolymers such as chitosan for more eco-friendly applications, and the integration of antimicrobial agents to provide dual functionality, pollutant removal, and water disinfection.

Polymer-based composites ranging from polymer/polymer and polymer/carbon composites to polymer/clay composites have been engineered to optimize selectivity and efficiency in water purification processes. These materials offer notable advantages over traditional adsorbents, such as increased mechanical strength, tunable properties, and enhanced recyclability, which collectively contribute to more sustainable and effective water treatment solutions.

This Special Issue seeks to showcase the latest research and reviews articles that explore innovative polymeric composites, including the application of machine learning and artificial intelligence models for optimizing water treatment processes. We aim to gather cutting-edge contributions that push the boundaries of polymer adsorbents in tackling global water pollution challenges.

Microbial fuel cells (MFCs) are an emerging technology that converts the chemical energy stored in organic substrates into electrical energy using microorganisms as catalysts. However, their performance is often limited by the anode design and architecture. To address this, conductive anodes with well-defined pore sizes were manufactured via 3D printing and evaluated for electrical energy generation and wastewater treatment in microbial fuel cells. The maximum power density, coulombic efficiency, and accumulated biomass observed were 14.94 mW/m2, 4.87 ± 0.56%, and 0.186 ± 0.025 g, respectively, for the anode with a 2.3 mm pore size. The maximum chemical oxygen demand (COD) removal efficiency was 86.98 ± 1.89% for the anode with a pore size of 1.6 mm. However, this difference was minimal and not significant compared to the anode with a 2.3 mm pore size, which achieved 85.77 ± 2.31%. Additionally, the lowest internal resistance observed was 1246.44 Ω, corresponding to the MFC equipped with the anode with a pore size of 2.3 mm. Taken together, these results indicate that, when using 3D-printed anodes with controlled architectures, an intermediate pore size, neither too large nor too small, provides an adequate balance between electrochemical performance and efficient wastewater treatment in microbial fuel cells.
