ICEAS SBR Technology Enters Its 35th Year Of High-Quality Effluent Production In Tennessee

In the late 1970s, a wastewater treatment plant (WWTP) in Tullahoma, TN, built in 1955, was overloaded and deteriorating. The city of Tullahoma and its consultants began an extensive evaluation of different treatment options for the new plant, including oxidation ditch, in-channel clarifiers, and the Sanitaire Intermittent Cycle Extended Aeration System (ICEAS®) for a sequencing batch reactor (SBR) process. Today, the Tullahoma WWTP — the first in the United States to use the ICEAS process — continues to perform exceptionally well and has never exceeded permit requirements, even while operating up to 30 percent higher than its design flow capacity.
