Capacity of activated sludge for nitrification and denitrification
The capacity of activated sludge for nitrification and denitrification was monitored in batch experiments. Nitrification at different environmental conditions (pH and dissolved oxygen), and denitrification at different C/N ratios were performed. Sodium acetate (NaAc) was used as a source of carbon at a ratio of C/N 1-5. The nitrification process resulted in total nitrification at pH 7, 2-7, 3 and pH 7, 9-8, 0 at DO>1 mg/L. Nitritation was favorized at pH 7, 9-8, 0 and DO<1 mg/L. Denitrification at a rate of 45, 6 mg NO3-N/Lh, and the specific denitrification at a rate of 11, 2 mg NO3-N/g MLSS h during denitrification at C/N 3 were determined. Activated sludge from a municipal wastewater treatment plant in a concentration of 4.0±0.2 g MLSS/L was used in all experiments.
