Summary: Elemental sulfur autotrophic denitrification (S0AD) is a promising method for wastewater treatment with lower costs, zero carbon dioxide emission, and minimum sludge production. This study demonstrated the effectiveness of a pilot-scale S0AD packed-bed in removing nitrate to below the national standard, with temperature and bacteria species playing important roles. The findings provide guidance for the design and operation of S0AD packed beds in practical engineering.

Summary: Textile industry generates a large amount of wastewater with various polluting substances. Water reuse, especially with the combination of reverse osmosis and membrane bioreactor treatment, has become more common in this industry. In this study, the performance of an autotrophic sulfur-based denitrifying column was evaluated for the reduction of nitrate in the permeate of a lab-scale membrane bioreactor receiving real textile wastewater, as well as in the concentrate stream of a real-scale reverse osmosis plant used for water recovery from textile wastewater. The results showed that the sulfur-based column could achieve high denitrification performances for both the membrane bioreactor effluent and the reverse osmosis concentrate.

Summary: By changing the molar ratio of influent C/N/S, this study explored the denitrification performance and microbial community in mixotrophic denitrification systems. The results showed that the joint action of several genera, including Thauera, Pacacoccus, Fusibacter Pseudoxanthomonas, Thiobacillus, Sulfurovum, and Sulfurimonas, contributed to efficient denitrification. The relative abundances of Thauera, Thiobacillus, and Sulfurimonas increased after the addition of S2-, indicating a potential mechanism for improving denitrification performance in mixotrophic systems.

Summary: The practical application of anammox process is limited by the requirement of anaerobic environment. By utilizing sulfur oxidizing bacteria (SOB) to provide a better anaerobic environment, the cost of deoxidation in actual operation can be reduced. In a low substrate environment, Candidatus_Kuenenia becomes the dominant anammox bacteria, and the increase of Thiobacillus and Desulfovibrio abundance promotes sulfur recovery and utilization.

Summary: This study investigated and compared the utilization behavior of reduced sulfur (-2) compounds (S2-, FeS, and SCN-) in autotrophic denitrification process. The results showed that SCN- exhibited the best denitrification performance, while S2-system inhibited nitrate reduction and FeS system efficiently accumulated nitrite. Additionally, intermediates containing sulfur were rarely produced in SCN- system, and the utilization of SCN- was limited compared to S2-in coexistence systems. The study provides a theoretical basis for regulating and utilizing reduced sulfur (-2) compounds in autotrophic denitrification process.

Summary: The removal of eight typical pharmaceuticals (PhACs) in sulfur-driven autotrophic denitrification (SdAD) process was investigated. Results showed that ibuprofen (IBU) and ketoprofen (KET) were effectively removed compared to other six PhACs. The primary removal route for IBU and KET was biodegradation. The microbial community composition in the system changed significantly under long-term exposure to PhACs, but functional microbes, such as genus Thiobacillus, showed high tolerance and maintained high removal efficiency.

Summary: This study investigated the effects of combined stress of Ni(II) and salinity on anammox sludge in terms of performance, activity, functional enzyme, and extracellular polymeric substance (EPS). Results showed that Ni(II) concentration played a more important role in anammox performance and specific activity, while functional enzymes and EPS content were inhibited by the combined stress. These findings provide insights into the combined effect of nickel and salinity on the anammox system and have important implications for treating metal-rich saline wastewater.

Summary: This study investigated the activity descent and its mechanism of anammox granular sludge (AnGS) during long-term cryopreservation. The cryopreservation process of AnGS was divided into three stages: plummeting stage, maintaining stage, and descending stage in terms of activity index. A significant positive correlation was found between the ATP pool and the three-stage activity descent of AnGS. The ATP pool was replenished through the sequential consumption of endogenous energy substances, maintaining the activity of AnGS.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
