Abstract

The effect of organic carbon loadings (OCLs) on NH 4 +-N and Mn 2+ removal was investigated using a novel approach of biological aerated filter (BAF) for drinking water treatment system. Three different OCLs of 0.2, 0.5 and 1.0 kg COD/m 3.d were loaded into BAF which was operated in batch-wise at 24 h hydraulic retention time. The experiments resulted in higher COD, NH 4 +-N and Mn 2+ removal percentages at OCL of 1.0 kg COD/m 3.d with removal of 97.1%, 97.4% and 94.7%, respectively. The NH 4 +-N effluent concentration at this phase was lower than Malaysian standard of 1.1 mg NH 4 +-N/L and as for Mn 2+, the effluent was 0.3 Mn 2+ mg/L. However, at lower OCLs of 0.2 and 0.5 kg COD/m 3.d, the removals were only 47.6% and 93.1% for NH 4 +-N and 35.4% and 44.2% for Mn 2+, respectively. Therefore, increasing organic carbon loaded to BAF system has increased the simultaneous NH 4 +-N and Mn 2+ removal degree in drinking water.
