Sustainable biological processes for VMS abatement are limited by the low aqueous solubility of VMS. In order this limitation, the siloxanes (D4, D5, L2 and L3) removal performance of a two-phase partitioning biotrickling filter (TP-BTF) was study in terms of the empty bed residence time (EBRT) and the fraction of the organic phase (silicone oil). A decrease in the total VMS removal from 76 to 49% was observed when the EBRT was reduced from 60 to 15 min. The highest removals were achieved for D4 (53–84%) and D5 (69–87%), compared to the lower values recorded for L2 (19–45%) and L3 (31–81%). The increase in the share of silicone oil in the recycling mineral medium from 5 to 45% resulted in an improvement of the total VMS abatement from 35 to 52%. This enhancement was observed for L3 (21–50%), D4 (26–64%) and D5 (58–78%), whereas L2 removals remained < 25%. A highly specialized bacterial community dominated by the genus KCM-B-112 was retrieved at the end of the experiment. eng info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ © 2021 Elsevier Attribution-NonCommercial-NoDerivatives 4.0 Internacional Siloxanes removal in a two-phase partitioning biotrickling filter: Influence of the EBRT and the organic phase info:eu-repo/semantics/article
