| Abstract |
Granulation characteristics have been studied with an aerobic sequencing batch reactor(SBR). Organic loading of 2.46 ㎏ COD/m³/day followed by 4.14 kg COD/m³/day had been applied to the lab-scale SBR with a very short settling time during the operating cycle. The granulation proceeded to the diameter range of 3 to 5 mm with MLSS concentration of 12,000 ㎎/L at 45th days of operation while COD removal efficiency remained almost consistent after the granule formation. It has been noticed that aerobic granulation under the higher loading with a very short settling time seemed to be due to the microbial selection of better flocculating species. |
