Abstract
Biofilter response was determined as the capability to utilize total ammonia nitrogen (TAN) by ammonia oxidizing bacteria (AOB). Tau (Ï) values for ammonia oxidation were 40.73â¯dayâ1, 58.81â¯dayâ1 and 159.70â¯dayâ1 at 13â¯Â°C, 20â¯Â°C and 30â¯Â°C respectively. Total ammonia nitrogen substrate utilization rates as indicated in a decay plot differed significantly (Pâ¯<â¯0.05) between temperature regimes 20 and 30â¯Â°C. However substrate utilization between 13 and 20â¯Â°C were not different (Pâ¯>â¯0.05). Ammonia oxidation tau values were 118.20â¯dayâ1 and 223.50â¯dayâ1 at (20â¯Â±â¯3â¯Â°C) and (30â¯Â±â¯3â¯Â°C) diurnal temperatures respectively. These were significantly different (Pâ¯<â¯0.05). The data in this study can be applied to future seeded or acclimating biofilters operating within these temperature ranges.
