Special Issue Information

Dear Colleagues,

Ecosystem degradation and water pollution are global threats to the sustainability of flora, fauna and human mankind. Nature-based solutions (NBSs) are emerging as an important trend for developing low-cost and efficient technologies. However, there is still the need for more pilot plant and field studies to establish design parameters, various types of applications, large-scale performance evaluation and the demonstration of their socio-economic feasibility, among other important topics. The aim of this Special Issue is to gather in-depth information related to different NBSs oriented towards wastewater treatment and also to the restoration of degraded and/or polluted ecosystems. In this context, this Special Issue falls entirely within the scope of the journal Sustainability.

For this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Non-conventional wastewater treatment technologies;
  • Various applications of phytoremediation;
  • Constructed wetlands;
  • Floating treatment wetlands;
  • Ecosystem services of artificial wetlands;
  • Phycoremediation of wastewater;
  • Various strategies for degraded ecosystem restoration;
  • Polluted ecosystems restoration.

All manuscripts that are accepted after peer review will be published online immediately after proofreading is completed. We look forward to receiving your contributions

Waste streams, leachates, and wastewater often contain high-strength ammonia, which can be challenging to manage. Microbial fuel cells (MFCs) offer a promising solution for treating such a nuisance of high-strength ammonia. However, optimizing MFC operating conditions, at lower technology readiness levels, is crucial to achieve a sustainable and economically viable application. This study investigates the factors affecting ammonia nitrogen removal in MFCs. MFCs with a cation exchange membrane (CEM) exhibit a higher diffusion rate of ammonium ions from the anode to the cathode compared to those with a proton exchange membrane (PEM). In close circuit mode (CCM), MFCs with a Pt-coated cathode electrode achieved an ammonium removal efficiency of 96% in the cathode chamber. Moreover, a plain carbon cathode electrode yielded an 87.1% removal efficiency. These results indicate that the combination of a catalyst (Pt) and oxygen in the cathode chamber can effectively remove or recover ammonia nitrogen from wastewater. Simultaneously, the removal of ammonia nitrogen in a microbial electrolysis cell (MEC) was studied. At an applied potential of 1.0 V, an ammonium removal efficiency of 87.5% was achieved. It was concluded that ammonium losses in MFCs can occur through electron migration, volatilization, and biological processes such as nitrification and denitrification. Full article
