Summary: A wastewater treatment system utilizing sulfate-reducing and sulfide-oxidizing processes was developed for organic wastewater with high sulfate/sulfide content. The study investigated the impacts of COD/SO42- ratio and hydraulic retention time (HRT) on the removal efficiencies of sulfate, COD, sulfide, and electricity generation. The results showed stable COD and sulfate removal efficiencies of 94.8±0.6% and 93.0±1.3% during the 63-day continuous operation. A power density level of 18.0±1.6 mW/m2 was achieved with a sulfide removal efficiency of 93.0±1.2%. However, sulfide removal efficiency and power density gradually decreased after 45 days, potentially due to sulfur accumulation on the anode.

Summary: A sulfide autotrophic denitrification microbial fuel cell (MFC) was established to study the removal of nitrogen and sulfur and electricity generation. The results showed that simultaneous desulfurization and nitrate removal were feasible. Higher sulfide concentration favored electricity generation. Nitrate concentration had less effect on sulfide removal and electricity production. Lower external resistance improved nitrate removal efficiency. The microbial community structure differed between the anode and cathode chambers. This research provides a new idea and method for sulfur-and nitrogen-containing wastewater treatment.

Summary: A denitrifying sulfide removal microbial fuel cell was developed with a capacitor and operated in an alternate charging and discharging mode to utilize the produced electricity in-situ. Adjustment of electrode potentials and external resistance distribution was used to regulate substrate conversion, with 10-minute switching interval favoring sulfur and gaseous nitrogen formation. In-situ utilization of the produced electricity shifted microbial community structure and promoted nitrate reduction, achieving efficient total nitrogen removal and gaseous nitrogen formation.

Summary: A photocathode-microbial electrochemical coupling system (PC-MFC) using black phosphorus-doped titanium dioxide nanobelt (BP/TB) as a photocatalyst was constructed to degrade hydroxychloroquine (HCQ, used to treat COVID-19). The degradation efficiency of HCQ (100 mg/L) in the coupling system reached 73.7% within 8 hours, higher than photocatalysis (69.5%), MFC (25.6%), and adsorption (9.6%). The PC-MFC achieved complete degradation of HCQ (100 mg/L) within 96 hours, significantly higher than the MFC (51.1%).

Summary: Microbial fuel cell (MFC) is a bio-electrochemical system that uses electrogenic bacteria to generate electricity. By utilizing wastewater as feed, MFC can generate clean electricity while treating the wastewater. However, there are challenges in scalability and commercialization of this technology, which can be overcome by the use of ceramics. Ceramics can provide chemical and structural stability as separators, chassis, or electrodes in MFCs, and they are low-cost, eco-friendly, and readily available.

Summary: In this study, breeding wastewater was efficiently treated using an electroactive microbial community screened from the native microorganisms of the wastewater in microbial fuel cells. The results showed good power generation and high pollutants removal efficiency. The morphology characterization demonstrated the formation of a thick biofilm by the screened electroactive microbial community. Microbial community analysis revealed an increase in microorganisms associated with electricity generation and pollutant degradation, while pathogenic microorganisms were greatly decreased. These findings suggest that the MFC constructed using the screened electroactive microbial community can be a sustainable method for breeding wastewater treatment.

Summary: This study investigated the performance of an ecological floating bed-microbial fuel cell (EFB-MFC) coupled system for electricity generation and nitrogen removal. Results showed that introducing plants into the MFC system reduced resistance and increased voltage, while also improving NH4+-N and TN removal efficiency. Water spinach system showed the best performance, but rotten roots of windmill grass released extra NH4+-N which impaired nitrogen removal. Radial oxygen loss and root exudates played significant roles in enhancing electricity generation and nitrogen removal. Electrical stimulation of enzyme activity related to nitrogen removal and migration of NH4+-N contributed to enhancing nitrogen removal.

Summary: During condensation, applying an external electric field can effectively hinder flooding phenomena and improve the heat-transfer rate by manipulating droplets' motion. Increasing vertical electric field strength hinders vapor motion and decreases collision frequency, while increasing horizontal electric field strength improves condensation performance by enlarging the contacting area. Different electric field frequencies influence growth and nucleation, resulting in various condensation performances.

Summary: The explosive boiling of a Cassie-Baxter (CB) state argon film suspended on nanopillar-arrayed surfaces is systematically studied through molecular dynamics simulations. The onset time of explosive boiling increases with the thickness of the suspended liquid film due to the delayed local accumulation of energy. Although the hydraulic diameter decreases with increased nanopillar height, the onset time remains unchanged. This is because liquid argon atoms cannot infiltrate into nanogrooves, maintaining a constant area for heat transfer.

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.
