Special Issue Information

Dear Colleagues,

Biological wastewater treatment is a modern technique that is designed to degrade pollutants dissolved in wastewater by the action of microorganisms. This Special Issue of Water focuses on the current state of research on biological wastewater treatment. New research papers, reviews and case reports are welcome in this Special Issue.

This Special Issue aims to serve as a platform for new scientific evidence on the biological processes of contaminants (chemical, microbial, anthropogenic particles such as nanoparticles or microplastics) and their removal from water and wastewater, as well as articles devoted to advanced biological technological solutions and their applications in environmental remediation. 

Here are some examples of topics that could be addressed in this Special Issue:

  • Biological treatment technologies;
  • Wastewater treatment;
  • Hazardous pollutant abatement;
  • Biodegradation pathway;
  • Biofilm viability;
  • Extracellular polymeric substances;
  • Membrane-aerated biofilm reactor;
  • Bioelectrochemical system;
  • Semiconductor-biological hybrid system;
  • Microalgal–bacterial symbiotic system.

You may choose our Joint Special Issue in IJERPH.

Microbial fuel cells (MFC) are emerging technologies that can produce electricity while treating wastewater. A series of tests were carried out to evaluate the efficiency of this technology for treating dairy wastewater (DWW). The experiments used Shewanella baltica as an exoelectrogen in a small single MFC to treat simulated DWW. The impacts of various operational factors, specifically pH, hydraulic retention time (HRT), and chemical oxygen demand (COD) in the influent to the anode chamber, were investigated, and the effect of these variables on the output performance of the cell was evaluated. The best performance of the MFC was found when the pH, HRT, and COD were 8, 6.66 h, and 20,632 mg/L, respectively, in the scaled experimental setup. Under these conditions, the maximum power density and percentage removal of COD in terms of wastewater treatment ability were found to be 138 mW/m2 and 71%, respectively. It may be concluded that MFCs are suitable treatment technologies for treating dairy wastewater while potentially simultaneously generating power. Full article

In recent years, quinoid redox mediators (QRMs) have attracted increasing attention because of their key role in wastewater biotreatment. Previous studies have shown that the anaerobic respiration of many bacteria could be coupled to the reduction and reoxidation of quinone groups. Thus, QRMs are widely involved in the microbial transformation of various organic and inorganic substances. To date, few reviews have focused on the involvement of quinoid compounds in environmental pollution biotreatment processes. In this paper, we review the different types of QRMs that interact closely with microorganisms, the characteristics of those QRMs, the involvement of QRMs during the biotransformation of recalcitrant organic pollutants, heavy metal ions and metallic oxides, and their enhancement on microbial fuel cells. Finally, the future research focus and application prospects with regard to different types of QRMs are proposed. This study can improve our understanding of QRM-mediated environmental pollution biotreatment processes and provide fundamental guidance on what kinds of QRMs are practical for engineering applications.
