| description | The performance of ethanethiol removal in biotrickling filter was investigated by microorganisms fixed on iron oxide-based porous ceramsite (IPC) under different operating parameters conditions. Ethanethiol removal efficiency was examined as a function of inlet concentration, empty bed residence time (EBRT), and spray density of nutrient solution. The results showed that the optimized operation conditions and operation characteristics of biotrickling filter for this study were at the inlet concentration of less than 250 mg·m−3, the spray density of 0.24 m3·m−2 h−1, and the EBRT of 68.7 s. The variation of the EBRT of about 100 s and the spray density of about 0.24 m3·m−2 h−1 did not change the ethanethiol removal efficiencies at certain ethanethiol concentrations of less than about 300 mg/m3, respectively. The main metabolic product was sulfate such as SO42- under continuous long-running regime in filter. The ethanethiol desulfurization process better meets the Michaelis-Menien model with calculated kinetic degradation parameters Ks=7.96 mg·m−3 and Vm=221.73 g·m−3 h−1. |
