Dear Ashwini, please let me to talk a little bit about odour abatement by biofiltration generally. Commonly for biofiltration odorous substances a solid bad biofilter is used. The reason is that absolut concentrations of odorous compound in a waste air stream are low (with the exception of hydrogen sulphide and ammonium sometimes). To operate biotrickling filter under low massload conditions is a little bit tricky task. That is why I recommened to evaluate your decission to use biotrickling filter instead of a solid bad biofilter for odour abatement at first.

All parameters needed for biotrickling filter or solid bad biofilter design you can find in the following publication

https://application.wiley-vch.de/books/biotech/pdf/v11c_proc.pdf

For designing a biofiltration unit (does not matter what type you choose) you need to know the parameters mentioned in the above publication.

Best regards

Vit

Dear Ashwini,

have you checked:

Else I would take the main authors (from the respective reference list) and follow them starting from Scholar-Google (scholar.google.com)

Does this help?

best regards
