This research comparatively evaluated the removal of the most common VMS (L2, L3, D4, and D5) under aerobic conditions in a conventional biotrickling filter (BTF) and a two-phase partitioning BTF (TP-BTF) with silicone oil (at 30%) as organic phase. The TP-BTF showed a superior performance compared to the conventional BTF, increasing the total VMS removal from <30% in the BTF up to ∼70% in the TP-BTF. The highest REs in the TP-BTF were recorded for D4 and D5, reaching values of 80–90%, corresponding to ECs between 0.12 and 0.17 g m−3.h−1. Slightly lower values were obtained for L3 (70–80%), and the lowest performance was recorded for L2 (20–60%) due to the high vapor pressure of this siloxane and therefore its lower affinity by the organic phase. Surprisingly, despite the different inocula used, a similar microbial community was found by the end of operation of both BTFs, with KMBC-112, Reynarella and Chitinophaga as the dominant genera.Junta de Castilla y León y EU-FEDER (CLU 2017-09 and UIC 071)European Union’s Horizon 2020 research and innovation program. grant agreement no. 745785Elsevier2020info:eu-repo/semantics/articleinfo:eu-repo/semantics/acceptedVersionapplication/pdfhttps://doi.org/10.1016/j.chemosphere.2020.126359https://uvadoc.uva.es/handle/10324/47066reponame:UVaDOC.
