How to Provide Nitrite Robustly for Anaerobic Ammonium Oxidation in Mainstream Nitrogen Removal

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(51), P. 21503 - 21526

Innovation in decarbonizing wastewater treatment is urgent response to global climate change. The practical implementation of anaerobic ammonium oxidation (anammox) treating domestic the key reconciling carbon-neutral management with sustainable development. Nitrite availability prerequisite anammox reaction, but how achieve robust nitrite supply and accumulation for mainstream systems remains elusive. This work presents a state-of-the-art review on recent advances anammox, paying special attention available pathways (forward-going (from nitrite) backward-going nitrate nitrite)), controlling strategies, physiological ecological characteristics functional microorganisms involved supply. First, we comprehensively assessed nitrite-oxidizing bacteria control methods, outlining that these technologies are transitioning possessing multiple selective pressures (such as intermittent aeration membrane-aerated biological reactor), integrating side stream free ammonia/free nitrous acid suppression recirculated sludge treatment), maintaining high activity ammonia-oxidizing competing oxygen bacteria. We then highlight emerging strategies supply, including production driven by novel microbes (ammonia-oxidizing archaea complete ammonia bacteria) reduction (partial denitrification nitrate-dependent methane oxidation). resources requirement different analyzed, hybrid pathway combining partial nitrification encouraged. Moreover, data-driven modeling process well proactive microbiome proposed hope achieving application. Finally, existing challenges further perspectives highlighted, i.e., investigation nitrite-supplying bacteria, scaling-up from laboratory under real conditions, stable performance fundamental insights this aim inspire advance our understanding about provide robustly shed light important obstacles warranting settlement.

Nitrogen cycling process and application in different prawn culture modes

Reviews in Aquaculture, Journal Year: 2024, Volume and Issue: 16(4), P. 1580 - 1602

Published: April 9, 2024

Abstract Nitrogenous waste is a global concern in aquatic ecosystems. In the shrimp farming system, feeding main input of nitrogen, which leads to accumulation nitrogenous waste, such as ammonia, nitrite, and nitrate. Nitrogen cycling crucial for removal stability aquaculture system. Under action different functional microorganisms, variety nitrogen pathways can be used transformation waste. Understanding complexity cycle necessary improving environment. This review examines many components mechanisms involved including nitrification, denitrification, anammox, heterotrophic assimilation, autotrophic assimilation. Because difference characteristics, culture modes are diverse. The current application outdoor pond mode indoor industrialized mode, was presented combination with requirements dissolved oxygen (DO), organic matter, carbon–nitrogen ratio, light, other environmental factors. Overall, denitrification processes According characteristics utilizing enhance efficiency cycle, facilitate elimination optimize water environment, improve overall benefits.
