Summary: Biological assimilation of nitrogen from wastewater to biomass offers an environmentally friendly solution. This study demonstrates the simultaneous removal and recovery of nitrogen from wastewater by a nitrogen-assimilating Acinetobacter sp. DN1 strain without N2O emission. The mechanism involves direct and indirect pathways for ammonium removal and the conversion of over 70% of the ammonium into intracellular nitrogen-containing compounds. This research provides a new direction for nitrogen removal and recovery without N2O emission.

Summary: Plants uptake and assimilate nitrogen from the soil, and nitrate and ammonium transporters play important roles in this process. Nitrogen is then incorporated into organic compounds through nitrogen metabolism pathways. Nitric oxide has been found to enhance plant survival under drought stress, and the interaction between nitrogen and salt stress has been studied. Excessive use of nitrate fertilizers can have negative impacts on health and the environment, highlighting the importance of alternative strategies. Genomics can identify new genes related to nitrogen fixation, which can be utilized to improve plant productivity.

Summary: In this study, a three-dimensional bioelectrochemical reactor system (3D-BERs) with granular activated carbon (GAC) was used to investigate the simultaneous removal of nitrates through autotrophic-heterotrophic denitrification under different pH levels. The results showed that both autotrophic and heterotrophic denitrifying microorganisms played a crucial role in the denitrification process when the influent COD/NO3--N ratio ranged between 1.5 and 3.5. The highest removal efficiency of nitrates (98.62%) was achieved at an initial pH of 7.5 ± 0.4 with a COD/NO3--N ratio of 1.5, while an efficiency of 81.12% was achieved at an initial pH of 8.2 ± 0.3 with a COD/NO3--N ratio of 3.5. The bacterial community structure and diversity at the genetic level changed with the immobilized GAC particles, enabling enhanced removal of nitrates at different surfaces of the immobilized GAC carriers.

The results showed that metronidazole could be rapidly degraded in the bioelectrochemical system, with a degradation rate higher than that in open circuit and nonbiological cathode systems. Increasing the electric current accelerated the degradation process, while increasing the initial metronidazole concentration slightly reduced the degradation efficiency. Additionally, high-throughput sequencing analysis revealed significant differences in microbial community structure among the tested systems.

Summary: This study constructed three-dimensional biofilm electrode reactors (3D-BERs) to assess the effects of metronidazole (MNZ) on autotrophic denitrification systems. The results indicated a slight decrease in nitrogen removal efficiency as the MNZ concentration increased. The 3D-BERs demonstrated excellent ability to degrade MNZ, especially at a concentration of 10 mg/L. High-throughput sequencing analysis revealed significant changes in the bacterial community under different MNZ concentrations, affecting the abundance of genes involved in nitrogen metabolism. The findings provide a theoretical basis for studying the toxic effects of antibiotics on denitrification processes and guidance for controlling antibiotics and nitrogen pollution in ecosystems.

Summary: Flow-electrode capacitive deionization (FCDI) is a sustainable technology for ion removal, although its energy consumption is relatively high compared to other desalination technologies. By simulating the energy consumption of each FCDI component, this study aimed to optimize the main components and improve our understanding of the energy consumption. The results showed that the flow electrodes had the highest energy consumption, while the ion-exchange membranes and desalination chamber contributed the most to the overall energy consumption. By adding titanium mesh to the flow electrodes and desalination chamber, the energy consumption of the optimized FCDI decreased by 51.9%.

Summary: In this work, an optimization model is proposed to handle the uncertainty of boosters in water distribution systems (WDSs). The model can handle the nonlinear and interval objective function, interval left-hand sides of constraints, and trapezoidal fuzzy uncertainty of the right-hand sides of constraints. The model was applied to two case studies to obtain optimal cost intervals for boosters. The results showed that the lower and upper bounds of costs increased with confidence levels, preference parameter lambda values, and the number of boosters. Additionally, boosters located far from the source were beneficial for reducing costs. Operation costs decreased with an increase in booster numbers and increased with lambda values and confidence levels. The obtained results can assist managers in making economical decisions for booster numbers and injection rates under uncertainty.

Summary: This study proposed a model for the design, location, and operation of disinfection boosters. The model was solved by two linear sub-models. Experimental results showed that the booster injection rates, operational costs, and capital costs increased with the credibility levels. It was also found that the booster costs were higher under trapezoidal distribution compared to triangular distribution, except for the credibility level of 0.5. Additionally, increasing the maximum booster number led to a decrease in operational costs, an increase in capital costs, and the total costs may increase or decrease depending on the relative magnitude of operational costs to the total costs.

Summary: Photocatalytic reduction of CO2 into valuable resources is an efficient solution to mitigate the energy crisis and effects of climate change. However, the low efficiency of photocatalytic CO2 reduction under visible light limits industrial applications. In this study, Au-doped BiOBr nanosheets with enhanced electrochemical characteristics were successfully synthesized, resulting in a 2.5 times higher charge separation efficiency compared to BiOBr nanosheets. The Au-doped samples also exhibited an outstanding photocatalytic capacity for converting CO2 to CO, with a yield rate four times higher than that of the untreated nanosheets. The mechanism of CO2 reduction was elucidated using in situ Fourier-transform infrared spectroscopy. This study provides a facile method for achieving efficient reduction of CO2 through Au-doping modification of BiOBr nanosheets.
