| Abstract | Abstract This study was conducted to evaluate the kinetics of simultaneous removal of COD, NH 4 + -N and Mn 2+ in a biological aerated filter (BAF) system. The evaluation was performed in a BAF system under various conditions of organic loading rates (OLRs) (0.2–1.0 kg COD/m 3 d), aeration rates (ARs) (0–2 L/min) and hydraulic retention times (HRTs) (6–24 h). Increasing the OLR and AR in the BAF system increased simultaneous COD, NH 4 + -N and Mn 2+ removal. Meanwhile, decreasing the HRT resulted in an insignificant impact on COD and NH 4 + -N removal, but Mn 2+ removal was significantly affected. The Monod model was used to estimate the kinetic coefficients of μ max and K S for the three substrates, i.e. COD, NH 4 + -N and Mn 2+ . The kinetic coefficients were found to be 0.28 d −1 ( μ max , COD ) and 5.1 mg-COD/L ( K S , COD ) for COD, 0.17 d −1 ( μ max ,NH4+-N ) and 0.03 mg-N/L ( K S ,NH4+-N ) for NH 4 + -N, and 0.28 d −1 ( μ max ,M2+ ) and 0.03 mg-Mn 2+ /L ( K S ,M2+ ) for Mn 2+ . From the Monod parameter estimation, the specific growth rate of biomass cells was adequately predicted for high quality effluent of simultaneous COD, NH 4 + -N and Mn 2+ removal. |
