Summary: Nitrate contamination of groundwater is a global health concern. Autotrophic denitrification using biogenic sulfur as a substrate has emerged as a sustainable and efficient method for treating contaminated groundwater. However, the effects of moderate temperature and biomass concentration on the performance and fouling of the system were not previously investigated. The study found that optimal biomass levels can limit membrane fouling but also affect denitrification efficiency. The temperature decrease significantly reduced denitrification efficiency, which could be partly recovered through bioaugmentation.

Summary: This study investigated the impact of influent nitrate loading on nitrite accumulation during denitrification process and proposed the use of thiosulfate to mitigate the nitrite accumulation. Results showed that increasing nitrate loading exacerbated nitrite accumulation, but thiosulfate effectively reduced nitrite accumulation. However, nitrite accumulation rebounded with higher thiosulfate dosages, indicating accelerated nitrate and nitrite reduction rates alternately. Thiosulfate addition also led to significant growth in relative abundances of sulfurimonas and ferritrophicum.

Summary: Sulfur autotrophic denitrification has become a research focus in recent years, however, traditional packed bed reactors have drawbacks such as small sulfur specific surface area and easy blockage. A sulfur-based fiber carrier fixed-bed reactor (SFFR) was developed to overcome these issues and showed higher denitrification efficiency due to the large sulfur specific surface area. The reactor also promoted endogenous denitrification, resulting in decreased sulfate productivity compared to the theoretical value. The SFFR had advantages including higher electron utilization rate, lower sulfur consumption, lower acid production and smaller sludge production.

Summary: The study demonstrated that the sulfur-based autotrophic denitrification integrated with biomass-based heterotrophic denitrification system (SBD) is an efficient way to remove nitrate from wastewater, showing advantages such as shortening start-up period, reducing sulfate productivity, and maintaining good denitrification performance. The optimal filter for the SBD system was a mixture of elemental sulfur powder, shell powder, corncob powder, and sawdust powder, with an average nitrate reduction rate of 420 mg NO3-N.L-1.d(-1) achieved at the end of the study. Major autotrophs in the SBD systems included Thermomonas, Ferritrophicum, and Thiobacillus, while major heterotrophs included Saprospiraceae, Ferruginibacter, Dokdonella, and Simplicispira, indicating the feasibility and practicality of the SBD system for nitrate removal from wastewater.

Summary: An electrochemical membrane with a Ru and Ni metal heteroatom interface was developed to enhance the utilization efficiency of atomic hydrogen (H*) for bromate reduction. The RuNi membrane achieved 91.3% bromate removal at 5 mA cm-2 under flow-through operation. The bromate reduction was mainly attributed to H*-mediated reduction, and adsorbed H* significantly contributed to bromate removal during membrane filtration. The formation of Ru0Ni0 structure on the electrochemical membrane facilitated H* generation during bromate reduction.

Summary: During long-term application, membranes will inevitably reach their end of life. The current approach of replacing end-of-life membranes with new ones constrains the economic efficiency and sustainability of membrane-based wastewater treatment. This study proposed a chemical cleaning-solvent treatment-hydrophilic modification strategy to regenerate end-of-life polyvinylidene fluoride (PVDF) membranes. The regenerated membranes showed comparable water permeance to new membranes and exhibited better antifouling performance. The membrane regeneration reduced expenditure and carbon emission compared to conventional membrane replacement.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
