Summary: Accelerants, such as MAX phase titanium aluminum carbide (MAX), multilayer Ti3C2TX MXene (ML-MXene), and few-layer Ti3C2TX MXene (FL-MXene), can improve the anaerobic performance of microbial electrolysis cell coupled anaerobic digestion (MEC-AD), promoting CH4 production and CO2 reduction. The highest CH4 yield (358.7 mL/g VS) and lowest CO2 yield (57.4 mL/g VS) were achieved with MEC-AD using 0.035 wt% ML-MXene. The digestates from MEC-AD with 0.035 wt% ML-MXene showed superior thermal stability (40.9%) and total nutrient content (42.1 g/kg), and the ML-MXene increased the abundances of Methanosarcina and Methanobacterium. These findings highlight the potential role of MXene in promoting methanogenesis and provide a new avenue for the development of MXene accelerants for MEC-AD systems.

Summary: This paper presents the results of research on the kick-off process of fermentation in three selected biogas plants in Poland. Supplementing a dedicated mixture of microelements in the first days of fermentation chamber kick-off has a positive effect on stabilizing the methane fermentation process and allows for faster and higher loading of fermenters with dry organic matter. This shortens the kick-off process time and reduces costs significantly.

Summary: This study demonstrates that different types of hydrochars produced in hydrothermal carbonisation have varied impacts on the original digestates in terms of quality, total solids content, energy content, carbon content, phosphorus content, and nitrogen content. The energy content of hydrochars produced in HTC treatments is similar to that of digestates, but ash content increases. HTC treatments also yield filtrates with high soluble chemical oxygen demand and methane potential, while concentrations of pharmaceuticals and heavy metals are low.

Summary: The study investigated the removal of different natural organic matter components from boreal lake water in a full-scale drinking water treatment plant using granular activated carbon filters containing different commercial carbons. Results showed that coagulation-flocculation, flotation, and chlorine dioxide oxidation were effective in reducing organic matter content, while sand and GAC filtration were efficient in removing BDOC. It was concluded that complementary analyses such as LC-OCD, FEEM, and BDOC are beneficial for optimizing NOM removal in DWTPs, and comparing different GACs in full-scale studies is important due to variations in TOC removal efficiencies.

Summary: Contamination detection in drinking water is crucial for water utilities. Current online water quality sensors have limitations, so we used flow-imaging particle counters and conventional sensors to assess their responses. The flow-imaging particle counter detected all contaminants, with the oxidation-reduction potential sensor performing the best. Particles smaller than 1 mu m were important for detecting contaminants, but had lower response compared to larger particles due to fluctuations. Monitoring particles larger than 1 mu m or specific particle classes can improve contamination detection.

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.
