Special Issue Information

Dear Colleagues,

Rapid urbanization and industrialization has contrarily stimulated the generation surplus quantity of toxic wastewater, which have become the major global formidable environmental concern. The industrial wastewaters are characterized based on the presence of specific contaminants, which are remnant of chemicals used or produced during industry processing. Therefore, the suitability of wastewater treatment technique depends on the source and composition of the industrial effluent. The method should also be eco-sustainable, economically feasible and avoid secondary waste generation. The development of economically feasible technologies holds the key to explore at wider industrial wastewater sector. Although, various methods such as up–flow anaerobic sludge blanket reactor, Bio–filter, sequential batch reactor, membrane bioreactor etc. are in use to serve the domestic and industrial wastewater treatment, but those techniques have certain limitations (such as low removal rates, low reactor loading rates, influent shock, process instability etc.) that prohibits wider application. Thus, advanced treatment technology are required to achieve effective eco–sustainable wastewater treatment. Therefore, this special issue will focus to cover various new techniques and processes for development of suitable wastewater treatment technologies, which support coupled bioenergy production and contribute to circular economy through resource recovery.

Articles are invited and encouraged on the following potential topics, but are not limited to, the following:

  • Anaerobic–aerobic systems for wastewater treatment
  • Bio–electrochemical systems for wastewater treatment and coupled bioenergy generation
  • Utilization of agro–waste material for wastewater treatment
  • Novel configuration and processes for mitigation of greenhouse gas emission from wastewater

A pyrrhotite and sulfur-circulating packed bed reactor (PS-CPBR) was constructed to study the removal process and mechanism of NO3-N and PO43−-P with different electron donors. The results showed that the NO3-N and PO43−-P removal performance of mixed electron donors (pyrrhotite and sulfur) was superior to the single electron donor (pyrrhotite). The optimum conditions of NO3-N and PO43−-P removal in the PS-CPBR were a hydraulic retention time (HRT) of 12 h and a C/N of 0, and the average removal efficiency was 100% and 86.39%. The sulfur in mixed electron donors was able to promote the dissolution of pyrrhotite and the formation of polysulfide to increase the effectiveness of electron donors, promoting the removal of NO3-N, while the PO43−-P was removed in the form of FePO4 precipitation. Microbial and functional gene analyses demonstrated that different electron donors were able to influence the abundance of microbial communities and denitrification functional genes. Meanwhile, mixed electron donors were able to increase the protein content of biofilms and reduce the resistance of electron transfer between microorganisms and electrons. Full article
