AB  - A pilot-scale combined process consisting of an anaerobic baffled reactor (ABR) 
      and an aerobic membrane bioreactor (MBR) for the purpose of achieving easy 
      management, low energy demands, and high efficiencies on nutrient removal from 
      municipal wastewater was investigated. The process operated at room temperature 
      with hydraulic retention time (HRT) of 7.5 h, recycle ratio 1 of 200%, recycle 
      ratio 2 of 100%, and dissolved oxygen (DO) of 1 mg/L and achieved good effluent 
      quality with chemical oxygen demand (COD) of 25 mg/L, NH4 (+)-N of 4 mg/L, total 
      nitrogen (TN) of 11 mg/L, and total phosphorus (TP) of 0.7 mg/L. The MBR achieved 
      partial nitrification, and NO2 (-)-N has been accumulated (4 mg/L). Efficient 
      short-cut denitrification was occurred in the ABR with a TN removal efficiency of 
      51%, while the role of denitrification and phosphorus removal removed partial TN 
      (14%). Furthermore, nitrogen was further removed (11%) by simultaneous 
      nitrification and denitrification in the MBR. In addition, phosphorus 
      accumulating organisms in the MBR sufficiently uptake phosphorus; thus, effluent 
      TP further reduced with a TP removal efficiency of 84%. Analysis of fluorescence 
      in situ hybridization (FISH) showed that ammonia oxidizing bacteria (AOB) and 
      phosphorus accumulating organisms (PAOs) were enriched in the process. In 
      addition, the accumulation of NO2 (-)-N was contributed to the inhibition on the 
      activities of the NOB rather than its elimination.
