The efficiency of mainstream anammox processes in wastewater treatment plants is significantly influenced by the concentration of substrates, particularly the ratios of ammonium (NH4+) to nitrite (NO2−). Optimal substrate ratios are crucial for maximizing nitrogen removal efficiency. Wang et al. found that a NH4+-N: NO2−-N ratio of 1:1.20 was ideal for both curtain and bundle packing anammox fillers, indicating the importance of maintaining specific substrate concentrations for effective nitrogen removal. Similarly, Gasa observed that different ammonium to nitrite ratios affected the nitrogen removal performance in anaerobic sequencing batch reactors, with a higher nitrite concentration showing better anammox enrichment and nitrogen removal efficiency. The presence of readily biodegradable chemical oxygen demand (rbCOD) can also impact the efficiency of anammox processes. Yang et al. demonstrated that introducing rbCOD at a low concentration improved nitrogen removal by enhancing the suppression of nitrite-oxidizing bacteria (NOB) activity and promoting sludge granulation, which supports the anammox pathway. This suggests that the carbon/nitrogen (C/N) ratio is another critical factor affecting mainstream anammox efficiency. Temperature and organic matter concentration are additional factors that influence the anammox process. Zhou highlighted that granules and biofilms are more effective in treating wastewater under mainstream conditions, as they can resist low and mesophilic temperatures, and that chemical oxygen demand (COD) concentrations over 100 mg/L limited nitrogen removal, although higher temperatures mitigated this effect. Furthermore, the presence of inhibitory substances, such as heavy metals, organic matter, and salts, can affect the anammox process. Talan et al. emphasized the need for optimal operational conditions to mitigate the effects of these inhibitors. The novel SANIA process, integrating sulfate reduction, autotrophic denitrification, nitrification, and anammox, demonstrated that specific operational strategies, such as the use of moving-bed biofilm reactors (MBBRs) and oxygen-induced thiosulfate production, could achieve high nitrogen removal rates by developing high rates of denitratation and anammox. Challenges in mainstream anammox applications, such as the difficulty of out-selecting NOB and managing high C/N ratios, highlight the need for efficient strategies to retain anammox bacteria and improve performance in low-intensity wastewater. Innovations in reactor configurations, such as the use of hollow fiber membranes with zeolite-coated surfaces, have shown potential in enhancing the growth of anammox bacteria and improving total nitrogen (TN) removal by creating favorable microenvironments. Verma and Daverey discussed the significance of reactor configuration and operational strategy in harnessing the full potential of anammox, indicating that hybrid reactor systems and integrated processes could extend the mainstream applications of anammox worldwide. Lastly, a full-scale case study in a temperate zone of China demonstrated spontaneous anammox bacteria enrichment and stable nitrogen removal in mainstream conditions, providing valuable insights for optimizing mainstream anammox applications and designing energy-neutral wastewater treatment processes. In summary, the concentration of substrates, particularly the ratios of ammonium to nitrite, along with operational conditions such as temperature, C/N ratio, and the presence of inhibitory substances, play a crucial role in determining the efficiency of mainstream anammox processes in wastewater treatment plants. Strategies to manage these factors, including optimizing substrate ratios, introducing rbCOD, and employing innovative reactor configurations, are essential for enhancing anammox efficiency.What are the current advancements in adsorption technologies used for wastewater treatment?
