Summary: The study found that at low temperatures, methane production decreased and dissolved methane increased, leading to a reduction in methanogenic performance. The membrane rejection can offset the deteriorated anaerobic digestion, ensuring stable COD removal efficiency. However, at low temperatures, the increased microbial products and residual inorganic foulants can aggravate membrane fouling.

Summary: Baker's yeast industries generate highly polluted effluents, and anaerobic treatment is commonly used to treat them. However, challenges exist in biomass retention and COD compliance. A pilot scale anaerobic membrane bioreactor showed efficient COD removal for vinasse from a BYI, but also experienced issues with permeate quality due to the passage of inert organic compounds through the membrane.

Summary: The major triggers of nitrous oxide (N2O) production in a full-scale wastewater treatment plant were investigated based on seasonal monitoring and analysis, revealing that N2O emissions during nitrification were related to nitrite accumulation, temperature, ammonia loading rate, and the specific oxygen uptake rate ratio between ammonia oxidizing bacteria and nitrite oxidizing bacteria (SOUR-ratio). The study found that a higher sOUR-ratio was associated with a higher N2O production rate, while a lower sOUR-ratio correlated with a lower N2O production rate.

Summary: This study investigated the effect of temperature on soluble microbial products (SMP) and extracellular polymeric substances (EPS) in wastewater bioprocesses. The results showed that temperature had a greater influence on EPS compared to SMP. A temperature of 60 degrees Celsius was found to be suitable for general extraction purposes. Fluorometry analysis proved to be a sensitive and rapid method for semi-quantitative determination of SMP and EPS constituents, particularly the proteinaceous components. It has positive implications for robust wastewater process control.

Summary: Pretreatment of municipal sludge has the potential to improve anaerobic digestion and increase methane production. However, the increased soluble COD from pretreatment makes it difficult to estimate hydrolysis kinetics accurately. In this study, batch digestion tests were conducted to evaluate the impact of alkaline and thermal pretreatment and to determine a different method to estimate hydrolysis rates. The inclusion of semi-soluble COD and volatile fatty acids in the hydrolysis kinetics model improved the accuracy of estimating the hydrolysis rates of pretreated solids.

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.
