In this study, we tested the performance and perspectives of four full-scale biotrickling filters based on Leca® (Light Expanded Clay Aggregates), a mechanically stable, non-degradable filter media, known to absorb odorous compounds such as H2S and methanethiol. The four filters varied in: filter thickness, carrying media, and the presence of dust filters. Biological Leca® filters, operated with EBRT between 1.7-8.9 s, were found to be capable of reducing NH3, H2S and odour, from a pig house, by up to 96%, 81% and 80%, respectively. Clogging was observed to occur after approximately 100 days, however the installation of a dust filter was observed to minimize this problem. © 2015, Int.
