Summary: This study proposed and validated the application of a dual-chamber bioelectrochemical cell as an add-on unit for an aerobic bioreactor to facilitate reagent-free pH-correction, organics removal, and caustic recovery from alkaline and saline wastewater. The results showed that the BES concurrently removed the majority of the influent organics and reduced the pH, enabling caustic production at a lower electrical energy demand compared to conventional chlor-alkali processes. The proposed application of BES holds promise to improve the environmental sustainability of industries in managing organic impurities in alkaline and saline waste streams.

Summary: A lab-scale hybrid anoxic-oxic biofilm reactor (HAOBR) was constructed to treat domestic wastewater, showing increased removal efficiency of COD, NH4+ and TN with higher reflux ratio, especially at 300%. The high nitrogen removal at 300% reflux ratio is mainly attributed to the cooperation of nitrification, denitrification, and anammox.

Summary: This study demonstrates that the application of voltage in a bioelectrochemical system can effectively promote the activity of marine anammox bacteria in saline wastewater treatment, leading to an increase in nitrogen removal rate. The optimal voltage was found to be 1.5 V, which resulted in a 27.45% higher total nitrogen removal rate compared to without applied voltage. The study also revealed that higher voltage (>2.0 V) had a negative effect on MAB activity, but the bioactivity was recoverable after removing the high voltage.

Summary: The main challenge in municipal wastewater treatment using partial-denitrification/anammox (PD/A) in the anoxic zone is the effective enrichment of anaerobic ammonium oxidation (anammox) bacteria. This long-term study achieved a total inorganic nitrogen concentration of 11.2 ± 3.5 mg N/L in the effluent of a pure-biofilm anoxic/oxic reactor using real municipal wastewater, resulting in a removal efficiency of 77.4 ± 7.2%. The anammox contribution to total nitrogen removal was over 55%, and Candidatus Brocadia was the only anammox genus detected. The study highlights the robust enrichment of anammox bacteria using a pure-biofilm system, providing insight into the application of mainstream anammox in municipal wastewater treatment.

Summary: This study aimed to control highly toxic Nitrogenous disinfection by-products (N-DBPs) in drinking water. A two-point influent activated carbon-quartz sand biofilter was selected and found to have the highest removal rate for aromatic amino acid Tyrosine (Tyr) and the potential formation of DCAN, which is an important precursor of N-DBPs. The results showed that the biofilter effectively removed Tyr and reduced the DCAN generation potential, outperforming traditional filters.

Summary: The study showed that increasing salinity led to a decline in removal rates of COD, NH4+-N, TN, and TP. However, even at 16 g L-1 salt concentration, NH4+-N, TN, and TP removal rates still performed well. The detrimental effect of increased salinity on phosphorus-accumulating organisms and denitrifying phosphorus-accumulating organisms was observed, resulting in a gradual dependence on phosphorus-accumulating organisms for phosphorus removal.

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.
