Siloxanes removal in a two-phase partitioning biotrickling filter: Influence of the EBRT and the organic phase

Biogas contain minor concentration of volatile methyl siloxanes (VMS), responsible for severe damages in turbines or internal combustion engines. Sustainable biological processes VMS abatement are limited by the low aqueous solubility VMS. In order this limitation, (D4, D5, L2 and L3) removal performance a two-phase partitioning biotrickling filter (TP-BTF) was study terms empty bed residence time (EBRT) fraction organic phase (silicone oil). A decrease total from 76 to 49% observed when EBRT reduced 60 15 min. The highest removals were achieved D4 (53–84%) D5 (69–87%), compared lower values recorded (19–45%) L3 (31–81%). increase share silicone oil recycling mineral medium 5 45% resulted an improvement 35 52%. This enhancement (21–50%), (26–64%) (58–78%), whereas remained < 25%. highly specialized bacterial community dominated genus KCM-B-112 retrieved at end experiment.
