| Abstract |
Bulking or nonsettling activated sludge has intermittently disrupted operation of sewage treatment plants for years. One of the most common causes of bulking is the proliferation of filamentous growth. The establishment of filamentous growth is generally believed to be caused by conditions under which the filamentous organism propagates as fast or faster then the more desirable spherical aerobic (floc forming) bacteria. This work describes the use of H202 in laboratory and pilot activated sludge systems to eliminate filamentous growth. The pilot studies with step aeration and pure oxygen activated sludge were performed at the EPA-DC Pilot Plant in Washington, D.C. Operating conditions to prevent the reestablishing of the bulking sludge in the D.C. wastewater were also evaluated. |
