TI  - Bioreduction of para-chloronitrobenzene in drinking water using a continuous 
      stirred hydrogen-based hollow fiber membrane biofilm reactor.

AB  - para-Chloronitrobenzene (p-CNB) is particularly harmful and persistent in the 
      environment and is one of the priority pollutants. A feasible degradation pathway 
      for p-CNB is bioreduction under anaerobic conditions. Bioreduction of p-CNB using 
      a hydrogen-based hollow fiber membrane biofilm reactor (HFMBfR) was investigated 
      in the present study. The experiment results revealed that p-CNB was firstly 
      reduced to para-chloraniline (p-CAN) as an intermediate and then reduced to 
      aniline that involves nitro reduction and reductive dechlorination with H(2) as 
      the electron donor. The HFMBfR had reduced p-CNB to a major extent with a maximum 
      removal percentage of 99.3% at an influent p-CNB concentration of 2mg/L and a 
      hydraulic residence time of 4.8h, which corresponded to a p-CNB flux of 
      0.058g/m(2) d. The H(2) availability, p-CNB loading, and the presence of 
      competing electron acceptors affected the p-CNB reduction. Flux analysis 
      indicated that the reduction of p-CNB and p-CAN could consume fewer electrons 
      than that of nitrate and sulfate. The HFMBfR had high average hydrogen 
      utilization efficiencies at different steady states in this experiment, with a 
      maximum efficiency at 98.2%.
