Abstract

To remove the low concentration of methane biologically, a three phase fluidized bed bioreactor immobilized with Methylosinus trichosporium OB3b was used. Optimum pH, temperature and bed height for the operation were pH7.0, 30$^\circ C$ and 150cm, respectively. For the inlet methane concentration of 100-400ppm and flow rate of 2-4L/min, the removal efficiencies of the bioreactor using the activated carbon as a carrier were the range of 54-71%, whereas those using the biosand were the range of 45-56%. It was found that activated carbon was more efficient than the biosand for the removal of methane. When aeration tank was equipped with the bioreactor, the removal efficiency increased to 6-13% and maximum removal rate obtained in the experiment was 1184mg.CH$_4$/min.
