Abstract

The aerobic biological oxidation of 2-propanol (isopropyl alcohol, IPA) at extremely high concentrations in air by an enriched solvent-tolerant microbial consortium operating at ambient temperature was evaluated for six months. Solvent-tolerant microbial cells were immobilised onto porous glass pall rings and fed with either IPA or its metabolic product acetone as sole carbon source. Successful biofiltration of solvent vapour at a concentration of 24 g m-3 was achieved with oxidation of up to 100% total inlet carbon. The maximum IPA mass loading and IPA elimination capacity (EC) was 1700 g m-3 h-1. This performance exceeds all previous values published in the literature for similar processes. A slip feed experiment, using acetone, was also performed in order to assess the substrate specificity performance. The biofilter responded successfully to a switch from acetone to IPA as sole carbon source, displaying little reduction in overall organic carbon removal. © Selper Ltd, 2004.
