Gas/Substrate Fluxes and Microbial Community in Phenol Biodegradation Using an O2‐Based Membrane Biofilm Reactor
Phenol can be oxidized to the end products when oxygen is used as an electron acceptor. This study evaluated phenol oxidation in an oxygen‐based membrane biofilm reactor (MBfR). The system achieved highest oxidation of both phenol and glucose when the phenol loading and glucose loading was ∼4.7 and ∼55 g m−2 day−1, respectively. These conditions were sufficient to prove an O2 flux of at least 46 g O2 m−2 day−1. In the case of feeding solely with phenol, the MBfR accomplished the highest phenol oxidation (∼100%) when the phenol loading was about 5.6 ± 0.9 g m−2 day−1 and the O2 flux was higher than 13.4 ± 2.2 g O2 m−2 day−1. However, higher phenol loading could be compensated by a higher O2 pressure, and the best performance occurred when the phenol loading was 5.6 g m−2 day−1, the O2 pressure was ∼0.54 atm, and hydraulic retention time was 2.5 h. Membrane fouling caused a reduced O2 flux, which led to low phenol‐oxidation efficiency. However, the bacterial population present in MBfR was analyzed by PCR‐denaturing gradient gel electrophoresis and a low biodiversity was found.
