In order to evaluate the performance of newly developed dynamic state membrane bio-reactor (MBR) with MIA, a full scale plant with the capacity of 210 m³/d was operated for treating sewage. Due to the MIA, the effect of residual oxygen could be completely removed during the non-aeration period and recycle ratio could be reduced in 1 recycle-to-influent ratio. Even though the plant was operated in winter season, stable performance could be achieved (BOD, CODcr, SS, TN, TP and E. Coli removal efficiency; 98.2, 95.2, 99.8, 72.7, 71.4 and 99.9 % respectively). Therefore newly developed dynamic state MBR with the MIA can be one of the useful biological nutrient removals (BNR) process for stable nutrient removal. |
