In this system, the anaerobic Accepted 28 April 2014 membrane bioreactor is stuffed with granular activated carbon to construct an anaerobic hybrid fixed- Available online 28 May 2014 bed biofilm membrane bioreactor. The effluent turbidity from the AnHMBR system was low during most Handling Editor: Y. Liu of the operation period, and the chemical oxygen demand and 2-CP removal efficiencies averaged 82.3% and 92.6%, respectively. Furthermore, a low membrane fouling rate was achieved during the operation. Keywords: During the AnHMBR operation, the
