Nevertheless, the stable operation of the PN-anammox process has always faced significant challenges including unstable nitrite (NO2–) accumulation and nitrate (NO3–) generation. In this paper, it was first presented that NO3– and ammonium (NH4+) could simultaneously be degraded by anammox bacteria via an endogenous dissimilatory nitrate reduction to ammonium (DNRA) pathway followed by a traditional anammox reaction. The transmission electron microscopy images and the inhibition experiments results of penicillin G and iodoacetic acid suggested that the intracellular carbon (glycogen) inside anammox bacteria supplied electrons for this endogenous DNRA conversion of NO3–. The isotope experiments further demonstrated that the full endogenous DNRA transformation of NO3– was synchronized even in the presence of external NH4+. Based on this method, a PN-anammox system was established, and a high total nitrogen removal performance (95.50%∼100.00%) was achieved even with an unstable PN process. Our work further displayed the complex nitrogen metabolic mechanism of anammox bacteria, the obstacles in the PN-anammox process could be solved by relying on the endogenous DNRA function in anammox bacteria.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 3","pages":"1270–1280 1270–1280"},"PeriodicalIF":4.8,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key mechanisms of the bioelectrocatalytic process in inducing the cathode/anode biofilm development and the multiroutes of carbon/nitrogen metabolisms were elucidated. The results showed that increasing the cathode potential led to a higher CH4 production rate. In particular, when the cathode potential was adjusted to −0.8 V vs Ag/AgCl, the CH4 production rate increased rapidly to 14.5 ± 2.9 mL/L/day. Under these conditions, the NH4+-N removal in the anode chamber reached 90%, and the total nitrogen removal was 79.5 ± 1.8%. These findings confirmed the effective simultaneous achievement of CO2 electromethanogenesis and anode denitrogenation. Moreover, Methanobacterium was continuously enriched in the cathode biofilm, with an abundance of 13.9%. Similarly, the abundance of Candidatus_Brocadia (anaerobic ammonia oxidation bacteria genus) in the anode biofilm was increased from 2.9 to 10.9%. Applying bioelectrocatalysis can target functional microorganism enrichment, stabilize the system operation, and realize efficient nitrogen removal and CO2 electromethanogenesis. This study provides a beneficial supplement to the conventional anaerobic digestion technology for further enhancing simultaneous nitrogen removal of anaerobic digestate and biogas upgrading.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 3","pages":"1331–1343 1331–1343"},"PeriodicalIF":4.8,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this knowledge gap, we studied three predominant BAC homologues: BAC-C12, BAC-C14, and BAC-C16. These compounds are widely used in industrial applications and are frequently detected in surface waters, making them a priority for aquatic toxicity assessment and ALC development. A novel approach integrating quantitative structure–activity relationship (QSAR) and interspecies correlation estimation (ICE) models was developed to predict aquatic toxicity, validated with an experimental test. The expanded toxicity data set, including predicted and measured values, was used to develop species sensitivity distribution (SSD) models for deriving ALC. The criterion maximum concentrations (CMC) were determined to be 7.04, 6.66, and 5.72 μg/L for BAC-C12, BAC-C14, and BAC-C16, respectively, while criterion continuous concentrations (CCC) were 1.18, 1.11, and 0.95 μg/L for BAC-C12, BAC-C14, and BAC-C16, respectively.

The CuO@ATT/AC/PMS system achieved 96.5% SDZ removal within 60 min with only 0.03 mg/L of Cu leaching. In addition, the removal efficiency of SDZ reached above 90% across a wide pH range of 5–9 and operating temperature (25–35 °C). CuO@ATT/AC demonstrated exceptional stability and reusability, achieving a 95% removal rate for SDZ after five cycles.

The fabricated nanocatalysts were subjected to UV–visible spectroscopy, particle size analyzer, XRD, SEM, STEM–EDX, TEM, and FTIR. Also, the DFT B3LYP computational study shows that stable PdRuNPs form through Pd and Ru interactions with QPABA at the carboxyl OH sites on the G and F rings, respectively. The limit of detection for 1,4-dioxane was determined to be 0.034 ppb, which is below the U.S. Environmental Protection Agency’s advisory range. Additionally, combining liquid–liquid extraction with GC–MS for the detection of 1,4-dioxane registered a method detection limit of 0.033 ppb in real wastewater samples. In the scaled-up system, three actual wastewaters from a wastewater treatment plant in New Jersey containing 1,4-dioxane up to 300 ppm were able to be 100% removed within 30 min.

For instance, organics lead to decreases in electrode current and H2O2 production, especially in macromolecular matters. The cathode reaction seems to be changed from the O2 → H2O2 route to the O2 → •OH route, influenced by the metal ions. Particle electrodes, electrode assembly, and bubble-induced convection are applied together to overcome the mass transfer limitations and underutilization of the electroactive area here.

Results show that the state-of-the-art water consumption (32.8%) contributed less to the total QQWF (0.67 USD) than contaminant removal costs (67.2%). Hydrocarbon removal accounted for 71.1% of the qualitative footprint, highlighting the considerable loading of crude oil residues in the wastewater. Scenario simulations revealed a substantial increase (15.6-fold) in the QQWF under increased water tariffs, suggesting the potential of economic instruments for water conservation. Improved efficiency of water regeneration units could achieve a 12% reduction in the QQWF, underlining the importance of wastewater treatment technologies for promoting water reuse within industries.
