Summary: A novel concept of a self-forming dynamic bio-membrane for innovative wastewater treatment in a membrane bioreactor is presented in this study. The ESFDM bioreactor showed comparable COD concentration reductions to a conventional MBR but achieved higher reductions in nitrogen-containing nutrients and lower fouling rates. The microbial community structure in the ESFDM promoted bacterial growth and exhibited higher total cell count and diversity compared to the mixed liquor.

Summary: The discharged saline wastewater has a severe impact on the aquatic environment due to the limited treatment performance of many wastewater treatment techniques. Membrane bioreactor (MBR) processes, on the other hand, have shown potential in treating saline wastewater under different salinity levels depending on the adaptation of the microbial community. This study systematically reviews the application of MBR in the treatment of saline wastewater, focusing on microbial structure and treatment efficiencies. The concept of carbon dioxide capture and storage is also proposed for MBR-based saline wastewater treatment technologies to achieve zero emission targets in the circular economy.

Summary: Membrane-aerated biofilm reactors (MABRs) have attracted attention for their wastewater treatment performance, but face challenges with reactor design and low total nitrogen (TN) removal efficiency. This study evaluated a hybrid system of MABR integrated with an anoxic nano-biotechnological reactor filled with Granulated Nanoscale Oxyhydroxides of Fe (GNOF) media to improve nitrogen removal. The hybrid MABR-GNOF system achieved higher removal efficiencies than the MABR-only system, with an 18% increase in nitrogen removal at 12 hours of hydraulic retention time (HRT).

Summary: Microbiologically influenced corrosion (MIC) is a destructive phenomenon that can occur in diesel mixture storage tanks, particularly due to the presence of biodiesel. The study identified the bacteria responsible for MIC and found that B. licheniformis can produce gamma-polyglutamate as a corrosion inhibitor. This suggests that B. licheniformis-mediated biocorrosion may promote the use of biodiesel as an environmentally friendly biofuel.

Summary: Membrane-aerated biofilm reactor (MABR) is an innovative technology that solves aeration issues in traditional bioreactors. It uses a membrane to provide oxygen to biofilm grown on its surface, allowing bubbleless aeration with high oxygen transfer rates. MABR can also achieve nitrification-denitrification simultaneously due to counter-diffusion. The control of biofilm thickness is crucial for MABR performance and various methods have been proposed, along with the importance of membrane properties and configuration. MABR shows high pollutant removal rates in different wastewater treatments, including full-scale plants.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

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.
