Abstract

Biofiltration technology is widely utilized for treatment of ammonia gas, with one of its potential detrimental by-products being nitrous oxide, a powerful greenhouse gas. The present work intends to provide the relation between ammonia elimination capacity during biofiltration and nitrous oxide generation as product of incomplete denitrification. Four laboratory scale tubular biofilters in up flow mode (3 replicates receiving humidified air and ammonia and 1 control receiving only humidified air) will be studied and compared for three levels of ammonia volumetric loadings (4.8, 7.2, and 9.6 g m-3 h-1). Trends from the obtained ammonia and nitrous oxide relation in the laboratory will be evaluated for significance of nitrous oxide production under varied ammonia loadings.
