Abstract:

Design criteria for nitrification and denitrification of high-strength wastewaters are presented in two upflow submerged filters in series. Oxygen was a very important parameter effecting the ammonia removal rate in nitrification. The half-order and zero-order rate constants for nitrification were determined for the dissolved oxygen ranges of 2 to 3 mg/L and 4 to 5 mg/L, respectively. The transition from ammonia to oxygen rate limitation occurred at a bulk oxygen:bulk ammonia ratio of approximately 2.5 to 4, showing that nitrification was oxygen limited for practical purposes. In nitrification nitrite accumulation reached a considerable degree at bulk oxygen:bulk ammonia ratios lower than 5. Also, in denitrification the half- and zero-order rate constants were determined. The nitrite produced in the nitrification stage could be successfully reduced in denitrification without causing any inhibitory effect.
