| Abstract |
In this study, some of bacterial growth kinetic parameters were delineated and evaluated for the biological nutrient removal processes such as the A²/O, 4stage-BNR, Intermittent Cycle Extended Aeration System(ICEAS) and Intermittently Aerated Cylindrical Oxidation Ditch(IACOD) processes. Y_H values for the ICEAS process ranged from 0.71 to 0.74, and were higher than those for the other processes. It seems to indicated that organic carbons uptaked by microorganism were more used up for cell synthesis rather than for energy components in the ICEAS process. b_H for the ICEAS and IACOD processes were lower than those for A²/O and 4stage-BNR processes. The μ_(max·A) for the ICEAS was higher than those for the other processes, which indicated that desirable operating conditions for nitrifying bacteria`s growth were established. |
