Summary: This study showed that the EGSB-Bardenpho process with effluent reflux can effectively remove COD and TN from FLIP. Reflux helped to further remove EfOM and DON, thereby improving the quality of the effluent. The presence of TAN promoted the formation of cocci-dominated granular sludge in the EGSB reactor. The research findings provide valuable insights for developing FLIP treatment technologies.

Summary: This study investigated the response of aerobic granular sludge (AGS) to organic loading rate (OLR) shock from a proteomic level for the first time. Results showed that OLR shock destabilized the AGS system initially but eventually led to a new stability, with larger granules, higher biomass retention, enhanced nitrogen removal, and abundant Candidatus_Competibacter. Proteomic analysis revealed that the AGS system activated protection mechanisms through up-regulating metabolic pathways related to amino acid synthesis, aminoacyl-tRNA biosynthesis, and gluconeogenesis in response to OLR shock. Subsequent OLR-shocking tests showed up-regulation of pathways associated with glycogen synthesis and denitrification, primarily contributed by Candidatus_Competibacter based on species annotation analysis.

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: This study addressed the issues of sludge floating and uneven mass transfer in up-flow partial denitrification/anammox (PDA) reactors by implementing two strategies: adding biological carriers and applying mechanical stirring. The results showed that both strategies effectively prevented sludge flotation and deterioration of settling performance. Mechanical agitation had a more significant positive impact on PDA performance compared to the addition of biocarriers as it achieved more adequate mass transfer.

Summary: This study investigates the correlations among wettability, dimple curvature radius, and nucleation characteristics on nanostructured surfaces. The results show that nucleation sites are located in the interior of dimples. Increasing surface hydrophobicity or dimple curvature radius would make nucleation more difficult. The obtained critical sizes of nuclei from molecular dynamics simulations are larger than the results estimated by the classical nucleation theory. Additionally, increasing the dimple number benefits the nucleation probability and condensation performance.

Summary: Wetting and dewetting behaviors of Ag droplets on different Mo surfaces were studied using molecular dynamics simulations. Diffusion energy barriers of Ag droplets on the surfaces were analyzed, revealing the presence of precursor films and adsorption layers. Alloying improved the wetting ability of the Mo(111) surface, which had significant precursor films. The fastest dewetting rate was observed on the surface with the highest adsorption layer density. The same molecular kinetic theory model applied to both wetting and dewetting processes, and higher temperatures reduced the time to reach equilibrium.

Summary: In this study, the covalent organic framework TpPa(OH)2 was used for the first time as a pH-responsive adsorbent for copper ions from water. The Langmuir adsorption capacities showed that the process was endothermic and entropy-driven. However, the adsorption capacity decreased when proton attacks occurred at a low pH value. The pH-swing technique increased the adsorption capacity by creating excess sites on the exfoliated layers.

Summary: The eco-friendly treatment of complex textile and dyeing wastewaters is a pressing environmental concern. This study examined an approach that utilizes different treatment paths and integrated anaerobic-aerobic processes to treat high-strength and recalcitrant textile dyeing wastewaters. The results showed that polyaluminum chloride precoagulation was effective in removing over 97% of suspended solids (SS) and more than 70% of chemical oxygen demand (COD) in the suede fabric dyeing stream. Hydrolysis pretreatment also proved successful in removing up to 58% of COD and 83% of SS in other low-strength streams. Additionally, the integrated anaerobic-aerobic treatment achieved notable COD removal of up to 99% from high-strength wastewaters. The anaerobic granular sludge process demonstrated several advantageous attributes, including high feed loading, a smaller footprint, minimal sludge production, and good stability. Overall, the integrated anaerobic-aerobic treatment provides a robust and viable option for highly contaminated and recalcitrant textile dyeing wastewaters.

Summary: The aim of this study was to investigate the use of Chlorella sorokiniana SU-1 biomass grown on dairy wastewater-amended medium as a sustainable feedstock for the biosynthesis of 0-carotene and polyhydroxybutyrate (PHB) by Rhodotorula glutinis #100-29. Rigid cell walls of the microalgal biomass were broken down using 3% sulfuric acid and detoxified with 5% activated carbon. Fermentation using the detoxified microalgal hydrolysate (DMH) resulted in maximum biomass production of 9.22 g/L, with concentrations of PHB and 0-carotene reaching 897 mg/L and 93.62 mg/L, respectively. Upscaling to a 5-L fermenter increased biomass concentration to 11.2 g/L, with PHB and 0-carotene concentrations of 1830 mg/L and 134.2 mg/L.

Summary: This study investigated the treatment of mycelial dreg (RMD), a byproduct of Rifamycin production, using the thermal alkaline pretreatment (TAP)-anaerobic digestion (AD) process. The optimal conditions for TAP were determined to be a temperature of 140 degrees C, pH of 12, and reaction time of 3 h. Further optimization resulted in an 86.4% increase in cumulative methane production. The study also revealed the enrichment of fermentative bacteria and methanogens in the AD system, as well as a functional redundancy that contributed to system efficiency and stability. Additionally, genomic analysis showed that rifamycin-B may not affect the phosphotransferase component for carbohydrate transport. These findings provide valuable insights into the feasibility of TAP-AD for RMD treatment and the ecological properties and microbial mechanisms of AD systems.

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.
