Biofilm Systems for Nitrogen Removal from Industrial Wastewater: Technology, Design, Operation, and better understanding of N2O generation

About this Research Topic

Biofilm systems are applied worldwide for wastewater treatment. Even though this technology is well known for municipal wastewater treatment, less attention has been given to the application of biofilms to industrial wastewater. Furthermore, the possible N2O emissions in these different technologies (biofilters, moving bed biofilm reactors, etc.) is not well documented. N2O emissions can be attributed mainly to the nitrogen removal bioprocess such as nitrification, denitrification and ANAMMOX, leading to a rise in the atmospheric N2O concentration and the carbon (C) footprint of the WWTP. A lot of past research has addressed N2O emissions from suspended growth processes; however, much less is known about emissions from biofilm processes.

Nitrogen removal from industrial wastewaters can be challenging due to the high variability of their composition and potential toxicity. Biofilms feature higher resistance to inhibitors and shock conditions compared to suspended-growth systems. In addition, the understanding of N2O generation in this type of technology is still under research, especially when it is applied to industrial wastewater. Efforts to understand N2O production have been made in suspended biomass systems, focusing on municipal wastewater treatment; nevertheless, the study of industrial wastewater has been scarcely addressed. Thus, the goal of this Research Topic is to forward our knowledge on the application of biofilms systems to the treatment of industrial wastewaters, including the study of N2O generation.

We invite the submission of Original Research, Reviews, Mini Reviews, Perspective articles, and industrial case studies. The areas to be covered in this Research Topic may include, but are not limited to:
• Biofilm systems applied to industrial wastewater (e.g. aquaculture, anaerobic digestion, and mining effluents)
• Hybrid suspended-biofilm systems for nitrogen removal from industrial wastewater
• Kinetic, biofilm modelling and microbiology of N2O processes in the industrial wastewater treatment (fisheries, effluents from anaerobic digesters, aquaculture).


Keywords: biofilm systems, industrial wastewater, wastewater treatment, N2O, N2O generation


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
