biofilm samples for total nitrogen and estrogen removal

A sulfur-based biofilter enhanced by phosphate modified activated carbon as three-dimensional electrodes was constructed to simultaneously remove total nitrogen (TN) and estrogen from low C/N wastewater containing 1 mg/L 17-alpha-ethinylestradiol (EE2). Characterization analyses and microbial community structures (such as dominant bacteria and functional denitrifiers) were employed to unveil the underlying mechanism.
