A key factor in the selection of the most appropriate technology for odour treatment is the ability of the system to recover from process fluctuations and operational upsets. However, the number of studies focused on the robustness of biotechnologies for odour abatement is scarce. The objective of the present study was to perform robustness assays with different bioreactors at laboratory scale treating synthetic mixtures of odorous compounds at trace level concentrations (mg m-3 - µg m-3). The results show the capacity of the biotechnologies to recover from operational failures in short periods of time. Besides, a semi-quantitative study was conducted to compare the robustness of physico-chemical and biological technologies under real operating conditions. The study confirmed the previous results and supports biotechnologies as the optimal solution for odour treatment.
