Metagenome or environmental sample from Anaerobic hybrid reactor sludge
sludge metagenome
The widespread presence of antibiotics in municipal wastewater, such as fluoroquinolones, sulfonamides, and trimethoprim, poses a significant environmental threat by fostering antibiotic resistance. Conventional wastewater treatment plants are often ineffective at removing these persistent compounds. While anaerobic digestion via Upflow Anaerobic Sludge Blanket reactors is efficient for removing organic matter, its performance for eliminating antibiotics is inconsistent and can be inhibited by their toxicity. This study examines the effectiveness of hybrid UASB reactors employing various support materials, including granular activated carbon and polyurethane foam, in enhancing the removal of antibiotics and organic matter under different hydraulic retention times. Two mesophilic reactors were operated at hydraulic retention times of 24, 18, 12, 8, and 4 hours. The research aimed to compare the role of conductive and non-conductive media in improving process stability, microbial retention, and removal efficiency of antibiotics.
