Abstract :
[en] BACKGROUND: Two-phase partitioning bioreactors (TPPBs) are considered as a new technology for xenobiotic degradation in gaseous effluents. However, there is still a need for more knowledge on how to design and scale-up TPPBs. The partitioning of the two phases remains a misunderstood way of research. In particular, the impact of pollutant (isopropylbenzene), biomass and surfactant extract needs to be better evaluated. RESULTS:. An adaptated scale-down apparatus has been developed in order to quantify the speed of phase partitioning (SPP) into a plug flow section. Firstly, it was shown that isopropylbenzene (IPB) doesn’t destabilize more significantly the system. Secondly, respectively 0.5 g.L-1 and 0.05 g.L-1 of biomass and surfactant extract, separately or in mixture, were sufficient to ensure the stability of the two-phase system. Finally, a 100 m3 limit of scaling-up was suggested on the basis of the circulation time comparison. CONCLUSION: The scaling-up of an aqueous/silicone-oil TPPB was found to be definitely conceivable when the presence of biotic compounds were considered. However, further considerations are needed to verify our assumptions, in particular by taking into account the velocity field pattern in full-scale bioreactors and reproduce it in lab-scale apparatus.
