Summary: The present study investigated the influence of hydraulic retention time (HRT) on methane production in temperature-phase anaerobic co-digestion (TPAcD). The study found that the optimal HRT for methane production was 12 days, which achieved high biodegradation and methane yield. The results also revealed that microbial population changes in the process were related to methane production and organic loading rate.

Summary: In this study, the energy recovery from two-stage mesophilic-thermophilic anaerobic digestion of cheese whey was assessed. The maximum energy production rate of 53.2 kJ/(L d) was achieved at a COD level of 13.8 g O2/L, HRT in an acidogenic reactor of 10 h, and HRT in a methanogenic reactor of 48 h. The maximum energy yield of 14.42 kJ/g COD was obtained at a COD level of 9.2 g O2/L, HRT in an acidogenic reactor of 10 h, and HRT in a methanogenic reactor of 72 h.

Summary: This study investigated the effects of fluctuation disturbance of organic loading rate (OLR) on anaerobic digestion (AD) of municipal sludge. The performance of the AD reactors remained similar before and after disturbance, indicating their buffer capacity to OLR periodic fluctuation. Different microbial community at RNA level was observed in the two reactors, with greater changes in the thermophilic AD. The results showed that the thermophilic microbial community was more vulnerable, but the reactor performance could be maintained using the functional redundancy strategy under OLR fluctuation disturbance.

Summary: Anaerobic digestion is a promising technology for sustainable biogas production. The co-digestion of waste activated sludge and wheat straw improves biogas production, with thermophilic digestion showing higher performance than mesophilic digestion. Modeling the process using a time-series model and a partially connected recurrent neural network, optimized by a slime mold algorithm, effectively predicts biogas production and determines the optimal structure of the model.

Summary: Direct anaerobic sewage treatment is becoming more popular in intertropical developing countries due to its low carbon footprint. However, if dissolved methane in the effluent is not controlled, this advantage will be significantly reduced. This study develops a mathematical model to assess the temperature variations in the biofilter media and their effects on methane oxidation performance under different operating conditions. Practical recommendations for facilitating heat transport from the compost media to the surroundings are presented.

Summary: Sewage sludge needs to be stabilized for beneficial use and must comply with environmental regulations regarding pathogens. Three sludge stabilization processes were compared for producing Class A biosolids. The TP + TAD process was found to be more effective in reducing E. coli concentration compared to the TAD process. All three processes produced Class A biosolids and remained compliant after 72 hours of storage.

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.

The research focused on a green microalgae strain called Desmodesmus sp. The study aimed to understand key trends and optimization strategies by conducting experiments in both summer and winter seasons. The findings showed that maintaining low cell concentrations during periods of light inhibition was beneficial for nutrient uptake rates. Effective strategies for enhancing algae-based wastewater treatment included cell mass recycling and adjusting dilution rates based on light availability.
