Abstract
The objective of this study was to investigate the response characteristics and performance of a biofilter in theremoval of ammonia, as a malodor compound. A trickle-bed type biofilter was applied for this study, and operatedat the ammonia loading rate of 0.97-15.52 g/m3·h. The results of the experiment indicate that the critical loadingrate of ammonia to the biofilter was 10.7 g/m3·h and the elimination capacity was 11.6 g/m3·h. The analysis ofnitrogen mass balance in the reactor indicates that inlet nitrogen as gas phase was converted through the biofilterinto NH4+ (41.5% by mass), NO2- (43%), and NO3- (15%) as the available form of nitrogen in the effluent liquid.
Free ammonia concentration in the effluent liquid was estimated as being in the range from 0.14 to 2.93 mg/L(average 1.7 mg/L) during the experimental period.
