Performance And Behavior Under Transient Conditions For Membrane Bioreactor Treating Toluene Vapors

[Full Text]



B.Sundar, V.Saravanan, M.Rajasimman



Elimination Capacity: Membrane Bioreactor: Removal Efficiency: Toluene



Many petrochemical, polymer and paper industries uses the toluene as solvent for the processing it was used as the main compound in this study. The bench scale membrane bioreactor used for controlling the toluene as a main single pollutant. Toluene was treated effectively, with toluene influent concentrations maintained at less than 0.4 g m-3 and a total removal efficiency of over 96% achieved when the faced fluctuating loads. The maximum elimination capacity of the membrane biofilter system was 93.8 g m-3 h-1. The membrane bioreactor showed a quick response to the transient condition (shutdown, restart, and shock load) and the stability of the membrane bioreactor was maintained. Further, the Bacillus sphaericus and Pseudomonas alcaligenes bacterial isolate was identified as the predominant strain involved in the toluene biodegradation in membrane bioreactor
