“…In traditional biotechnological process for decreasing nitrogen and chemical oxygen demand (COD), the nitrification and denitrification reactions were performed in separated reactors owing to the different demand of various functional microbial communities (Zhang et al, 2013). Therefore, a lot of advanced technologies have been developed for the removal of nitrogen with low carbon nitrogen ratio, such as SND (Simulation Nitrification and Denitrification) (Zhao et al, 2017), OLAND (Oxygen Limited Autotrophic Nitrification Denitrification) (Nhu Hien et al, 2017), SHARON (Single reactor for High Activity ammonia Removal Over Nitrite) (Claros et al, 2012) and CANON (Completely Autotrophic Nitrogen removal Over Nitrite) (Zhang et al, 2013). Meanwhile, anaerobic ammonium oxidation (anammox) have been widely applied to nitrogen removal (Zheng et al, 2019), which was an energy-saving process without extra organic electron donor that oxidized ammonium and nitrite to N 2 (Wang et al, 2019b).…”

The efficient removal of nitrogen pollutants in the aquaculture systems is still a challenge due to the low concentration of organic carbon and high concentration of dissolved oxygen (DO) in the wastewater. The simultaneous partial nitrification, anammox and denitrification (SNAD) bioreactor was firstly used for the treatment of aquaculture wastewater in recirculating aquaculture system. The bioreactor operated for 180 days without adding extra organic carbon. After 60-day operation, the bioreactor reached the stable stage with the average concentration of ammonia/nitrate/nitrite/COD in the effluent with 0.26/0.75/0.47/0.27 mg/L. The Pseudoxanthomonas was the dominant genus in the biofilm samples. The typical nitrogen functional bacteria and genes for nitrification, anammox and denitrification were detected with different abundance in different procedures along the bioreactor. Network analysis revealed the significant correlations between nitrogen functional bacteria and genes. The SNAD bioreactor achieved the effective removal for nitrogen and COD under high DO conditions in recirculating aquaculture system.

“…The oxic reactor’s role was crucial in ammonia conversion to nitrate, evidenced by the increase in NO X concentrations ( Figure 2 d). This suggests the significant role of ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) in the nitrification process [ 36 ]. However, the higher NAR in the oxic reactor suggests incomplete nitrification, with a potential for nitrite accumulation that might necessitate further optimization of the system [ 37 ].…”

This study explores the effectiveness of an integrated anaerobic membrane bioreactor (AnMBR) coupled with an anoxic/oxic membrane bioreactor (A/O MBR) for the treatment of natural rubber industry wastewater with high sulfate, ammonia, and complex organic contents. This study was conducted at the lab-scale over a duration of 225 days to thoroughly investigate the efficiency and sustainability of the proposed treatment method. With a hydraulic retention time of 6 days for the total system, COD reductions were over 98%, which reduced the influent from 22,158 ± 2859 mg/L to 118 ± 74 mg/L of the effluent. The system demonstrates average NH3-N, TN, and total phosphorus (TP) removal efficiencies of 72.9 ± 5.7, 72.8 ± 5.6, and 71.3 ± 9.9, respectively. Despite an average whole biological system removal of 50.6%, the anaerobic reactor eliminated 44.9% of the raw WW sulfate. Analyses of membrane fouling revealed that organic fouling was more pronounced in the anaerobic membrane, whereas aerobic membrane fouling displayed varied profiles due to differential microbial and oxidative activities. Key bacterial genera, such as Desulfobacterota in the anaerobic stage and nitrifiers in the aerobic stage, are identified as instrumental in the biological processes. The microbial profile reveals a shift from methanogenesis to sulfide-driven autotrophic denitrification and sulfammox, with evidence of an active denitrification pathway in anaerobic/anoxic conditions. The system showcases its potential for industrial application, underpinning environmental sustainability through improved wastewater management.

“…Under anaerobic conditions, ammonia is used as the electron donor and nitrite as the electron acceptor, and ammonia nitrogen is oxidized to nitrogen gas, which has the advantages of low energy consumption, low residual sludge, and no additional required carbon source. Processes derived based on anammox have also become a hot research topic, such as single-stage short-course nitrification-anammox (SNAP) [4], partial nitrification-anammox (PDA) [5], SHARON-ANAMMOX [6], restricted autotrophic nitrification-denitrification (OLAND) [7], total autotrophic denitrification (CANON) [8], and short-course nitrification/anammox/denitrification-coupled denitrification phosphorus removal (SNAD-DPR) [9], which are important in the management of produced wastewater, waste leachate, and environmental pollution. The PDA process has attracted the attention of many scholars with its advantages of low energy consumption, low cost, and high efficiency of nitrogen removal, and has become one of the mainstream practical engineering applications.…”

Anaerobic ammonia oxidation (anammox) process is known as a low-energy and environmentally friendly process for treating nitrogen-rich wastewater. Anammox bacteria are the key microorganisms to achieve this biological process. However, the efficient enrichment of anammox bacteria has been a bottleneck for its practical application because of their slow growth and high sensitivity, and no pure culture has been found. Therefore, the development of efficient anammox bacterial enrichment techniques is of great theoretical and application value. Solving the problem of anammox bacterial activity and improving the process denitrification performance is one of the current research hotspots. In this paper, three aspects of anammox bacteria are described in terms of their physiological properties, environmental influencing factors, and short-term starvation tolerance; a systematic review of the latest research progress in accelerating the activity of anammox bacteria using enrichment strategies for process regulation, the construction of granulation models, suspended sludge biomass management, and strain preservation. Finally, the future frontier development of anammox bacteria was discussed and foreseen.
