Special Issue Information

Dear Colleagues,

Electrochemical processes are a truly innovative type of process for water and wastewater treatment, including anodic oxidation, cathodic reduction, the electro-Fenton process, etc. Electrochemical treatment has good application prospects in the removal of refractory organics, emerging contaminants, and pathogenic microorganisms. In electrochemical treatment, it is important to understand the removal mechanisms of the pollutants, including the direct/indirect oxidation processes, the generation and reaction of various radicals, the transfer and transformation of the target pollutants, and dynamics and thermodynamic analysis. We welcome the application of electrochemical technology in actual water treatment, such as drinking water, municipal wastewater, and industrial wastewater, whose stability and limitations should be taken into account. Moreover, the energy consumption and cost assessment of electrochemical treatment compared to traditional technologies are also crucial for its practical applications.

In this context, for this Special Issue in Water, the Guest Editors will consider studies that reflect the forefront development of electrochemical technology in the field of water treatment. Submissions of original research or review articles encompassing the recent findings and advancements in this field are welcome.

We look forward to receiving your contributions.

In this study, a constructed wetland–Fe3O4/granular activated carbon anode microbial electrolysis cell (CW-FMEC) was constructed to enhance denitrification in low COD/N ratio wastewater. The introduction of Fe3O4 boosted the expression of functional genes involved in the denitrification pathway, and the abundance of narG, nirS, and nosZ increased by 99.29%, 70.54%, and 132.18%, respectively, compared to CW. In addition, the content of c-type cytochromes (c-Cyts) and EPS were also enhanced in the CW-FMEC. The microbial communities study displayed that Thauera, Dechloromonas, and Arenimonas became the main genera for denitrification. The denitrification performance at different COD/N ratios was investigated in depth. Under optimal working circumstances, the CW-FMEC had an excellent nitrate removal rate (88.9% ± 1.12%) while accumulating nearly no NO2-N or NH4+-N in the effluent. This study provides a new direction for the development of CW-MEC and accelerates its implementation. Full article
