      biofilm reactor.

AB  - A membrane aerated biofilm reactor is a promising technology for wastewater 
      treatment. In this study, a carbon-membrane aerated biofilm reactor (CMABR) has 
      been developed, to remove carbon organics and nitrogen simultaneously from one 
      reactor. The results showed that CMABR has a high chemical oxygen demand (COD) 
      and nitrogen removal efficiency, as it is operated with a hydraulic retention 
      time (HRT) of 20 h, and it also showed a perfect performance, even if the HRT was 
      shortened to 12 h. In this period, the removal efficiencies of COD, ammonia 
      nitrogen (NH4(+)-N), and total nitrogen (TN) reached 86%, 94%, and 84%, 
      respectively. However, the removal efficiencies of NH4(+)-N and TN declined 
      rapidly as the HRT was shortened to 8 h. This is because of the excessive growth 
      of biomass on the nonwoven fiber and very high organic loading rate. The 
      fluorescence in situ hybridization (FISH) analysis indicated that the ammonia 
      oxidizing bacteria (AOB) were mainly distributed in the inner layer of the 
      biofilm. The coexistence of AOB and eubacteria in one biofilm can enhance the 
      simultaneous removal of COD and nitrogen.
