Evaluation of potassium ferrate activated biochar for the simultaneous adsorption of copper and sulfadiazine: Competitive versus synergistic

Jieru Yan et al.

Summary: Iron-modified biochar (Fe-BC) prepared in this study showed enhanced adsorption capability for copper and sulfadiazine compared to pristine biochar (BC). The iron modification enlarged the surface area and loaded iron oxide nanoparticles on biochar surface, improving the adsorption efficiency. In the binary-pollutants system, there was a synergistic effect on the adsorption of Cu2+ and SDZ, possibly due to mutual bridging effects and complexation between the two pollutants. Fe-BC700 exhibited better removal efficiency for Cu2+ and SDZ in the binary system compared to single systems.

New insights into different surfactants' impacts on sludge fermentation: Focusing on the particular metabolic processes and microbial genetic traits

Jingyang Luo et al.

Summary: Different categories of surfactants have been found to have positive effects on volatile fatty acid (VFA) production during waste activated sludge (WAS) fermentation. The presence of surfactants improves solubilization and hydrolysis steps, leading to enhanced acidification. Surfactant conditioning enriches functional microorganisms associated with VFA generation and increases the expression of key genes involved in the process. The bioavailable substrate improvement, functional bacterial enrichment, and metabolic activity upregulation induced by surfactants jointly contribute to VFA promotion during WAS fermentation.

Role and significance of co-additive of biochar and nano-magnetite on methane production from waste activated sludge: Non-synergistic rather than synergistic effects

Hong-Yu Jin et al.

Summary: This study investigated the effects of co-additive of biochar (BC) and nano-magnetite (NM) on anaerobic digestion and found that there were no synergistic effects. Methane production decreased by 24.7% and 38.3% in the simultaneous co-additive strategy, while it was slightly higher in the stepwise additive strategies compared to BC alone but lower than NM alone. Mechanism studies suggested that BC adsorbed soluble organics, reducing available substrates for methanogens.
