What is Thermophilic Biotrickling Filtration of a Mixture of Isobutyraldehyde and 2‐Pentanone about?

## Abstract In this study, the possibility of the removal of isobutyraldehyde and 2‐pentanone was investigated in biotrickling filters (BTFs) at higher temperature (52–65 °C). First, the biodegradation of isobutyraldehyde and 2‐pentanone in activated sludge was proven by batch experiments at 52 and 62 °C. In batch experiments isobutyraldehyde was also degraded up to a temperature of 72 °C. Thereafter two bioreactors were operated in parallel, one at ambient temperature (BTF25), and one at 52 °C (BTF52). Maximum elimination capacities of 97 and 139 g m^−3^ h^−1^ were observed in BTF25 and BTF52, respectively, for isobutyraldehyde. Maximum elimination capacities of 53 and 63 g m^−3^ h^−1^ were obtained for 2‐pentanone in BTF25 and BTF52, respectively. A significant difference was observed in the operational stability of the two reactors. In the reactor at ambient temperature, operational problems such as foam formation, higher biomass accumulation and organic acid production were observed. In the thermophilic reactor these problems did not occur or were less severe. Copyright © 2007 Society of Chemical Industry
