BACKGROUND: An alkaline mineral medium was used previously to enhance the absorption rate of hydrogen sulfide in a odor biofiltration process. In this work a high operating pH (?10) was used to perform the biotrickling filtration of carbon disulfide and ethanethiol odors, here a mathematical model was developed and validated under dynamic operation. RESULTS: The solubility of carbon disulfide and ethanethiol was increased around 50% and 80% respectively by using an alkaline mineral medium instead of pure water. The alkaline biotrickling filter reached maximum elimination capacities for carbon disulfide of 2.3 g m -3 h -1 and 3.5 g m -3 h -1 for ethanethiol case, both with removal efficiencies around 50%. CONCLUSION: The absorption of carbon disulfide and ethanethiol under alkaline condition is enhanced, nonetheless, the elimination capacity of the alkaline biotrickling filter was limited by the bacterial consortium activity, which was corroborated by the mathematical model.
