  • Treatment on low carbon-to-nitrogen micro-polluted water by layered biological aerated filter with floating and sunken media

    In order to improve the TN removal efficiency on low carbon-to-nitrogen micro-polluted water, in this study, a layered biological aerated filter (L-BAF) was built. The results showed that the removal efficiency for CODMn, NH3-N, and TN was 71.6–90.3%, 99.8–99.9%, and 57.8–65.7%, respectively, when the C/N ratio was kept at 3 and the volumetric ...
