“…In SAD process, the nitrate is first reduced to nitrite and step reduced to N 2 like the HD process. During the process of denitrification, sulfur compounds (S 0 , S 2− , SO 3 2− , S 2 O 3 2− ) provide electrons through the electron transfer chain to reduce nitrogen oxides (Deng et al, 2019;Ma et al, 2020;Grubba et al, 2022). These compounds then participate in more complex reactions which ultimately convert into SO 4 2− (Wu et al, 2020;Zhang et al, 2022a).…”

Wastewater treatment plants are the major energy consumers and significant sources of greenhouse gas emissions, among which biological nitrogen removal of wastewater is an important contributor to carbon emissions. However, traditional heterotrophic denitrification still has the problems of excessive residual sludge and the requirement of external carbon sources. Consequently, the development of innovative low-carbon nitrate removal technologies is necessary. This review outlines the key roles of sulfur autotrophic denitrification and hydrogen autotrophic denitrification in low-carbon wastewater treatment. The discovered nitrate/nitrite dependent anaerobic methane oxidation enables sustainable methane emission reduction and nitrogen removal by utilizing available methane in situ. Photosynthetic microorganisms exhibited a promising potential to achieve carbon-negative nitrate removal. Specifically, the algal-bacterial symbiosis system and photogranules offer effective and prospective low-carbon options for nitrogen removal. Then, the emerging nitrate removal technology of photoelectrotrophic denitrification and the underlying photoelectron transfer mechanisms are discussed. Finally, we summarize and prospect these technologies, highlighting that solar-driven biological nitrogen removal technology is a promising area for future sustainable wastewater treatment. This review has important guiding significance for the design of low-carbon wastewater treatment systems.

“…Practical wastewater systems contain organic carbon, nitrate nitrogen, and ammonia nitrogen in different concentrations, besides sulfurous substances. Therefore, various simultaneous desulfurization and denitrification technologies have been developed to deal with sulfurous wastewater pollution [ 98 ].…”

The definition of reactive sulfur species (RSS) is inspired by the reactivity and variable chemical valence of sulfur. Sulfur is an essential element for life and is a part of global geochemical cycles. Wastewater treatment bioreactors can be divided into two major categories: sulfur reduction and sulfur oxidation. We review the origins of the definition of RSS and related biotechnological processes in environmental management. Sulfate reduction, sulfide oxidation, and sulfur-based redox reactions are key to driving the coupled global carbon, nitrogen, and sulfur co-cycles. This shows the coupling of the sulfur cycle with the carbon and nitrogen cycles and provides insights into the global material−chemical cycle. We also review the biological classification and RSS metabolic mechanisms of functional microorganisms involved in the biological processes, such as sulfate-reducing and sulfur-oxidizing bacteria. Developments in molecular biology and genomic technologies have allowed us to obtain detailed information on these bacteria. The importance of RSS in environmental technologies requires further consideration.

“…The critical aim of wastewater treatment is to eliminate organic matter and remove nutrients (S, N and P), suspended solids, and soluble contaminants from wastewater. [104][105][106][107][108] At all events, the wastewater treatment processes consist of the physical processes (primary treatment), biological processes (secondary treatment), flocculation sedimentation, sand filtration, and membrane filtration efficient as the physiochemical process (tertiary treatment) for pathogen removal from wastewater. Additionally, based on, 109 it is important to highlight that the approaches, all of which use sand filters for infection removal in the handwash-wastewater treatment of COVID-19, will become more efficient if the use of biological processes and/or physical filtration is made.…”

Several studies have been directed to find scalable, swift, accurate, and costeffective strategies for detecting, monitoring, and treating coronavirus disease 2019 . Indeed, the lack of a fast and practical method for detecting the infected regions makes decision-making challenging to combat the critical pandemic-struck situations. The probable 'wrong', or rather inadequate, decisions not only have a boomerang effect on the economy but also can lead to an increase in the number of infected individuals, degree of hospitalization,This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
