Abstract: | Laboratory scale-studies on acetone biodegradation in a trickle-bed biofilter were carried out using using two identically sized columns, one of which was packed with coconut fibre and the other with plexiglass chips. The columns were inoculated with two strains of bacteria: Burkholderia cepacia (syn. Pseudomonas cepacia) and Acinetobacter baumannii. The continuous process of air purification was carried out at incremental acetone concentrations from 0.3 to 2.5 g m−3 air and air flow-rates from 0.1 to 0.3 m3 h−1. A maximum acetone elimination capacity of 95.8 g m−3 filter bed h−1 was achieved at air flow-rate of 36 m h−1. |
