| Research Abstract |
Ozonation-biological activated carbon (BAC) has been widely used as an advanced drinking water treatment. However, mechanism of biological treatment such as nitrification in biological activated carbon remains unknown. In this study, we investigated abundance and diversity of ammonia-oxidizing bacteria (AOB) and archaea (AOA) associated with BAC. The results indicated that dominant ammonia-oxidizers are AOA, not AOB. In addition, pre-chlorination severely inhibit the settlement of AOA on BAC.
