Research into the improvement of nitrification in a 2-line sewage treatment plant

, : Research into the improvement of nitrification in a 2-line sewage treatment plant. Korrespondenz Abwasser 38(1): 40-47

Comparative tests were carried out in a municipal sewage treatment plant with 2 separate aeration tanks involving (1) nitrification alone, and (2) nitrification with an upstream denitrification stage. The nitrification level was higher in tank 2, even though the space available for nitrification was less than in tank 1, being reduced by the volume required for the denitrification stage. However, the activity of ammonia-oxidizing bacteria, as measured in the return sludge, was lower in tank 2.
