Force Main Odor and Corrosion Control by SuperOxygenation, Knoxville TN

In 2007, Knoxville Utilities Board sought new methods for preventative, non-chemical, in pipe treatment and found unprecedented success in odor reduction by installing ECO2 SuperOxygenation technology. The ECO2 system is installed at an intermediate point along the force main to sustain aerobic conditions at the force main discharge to reduce the formation of hydrogen sulfide. The ECO2 system has successfully reduced untreated hydrogen sulfide gas in excess of 800 - 1000 ppm to an average of under 100 ppm at the force main discharge. This is being done at a capital and annual operating cost resulting in a 3 - year payback versus alternative chemical treatment. Resulting from the reduction in H2S, a second ECO2 system is currently being installed at the force main pump station to further reduce the H2S from 100 ppm to less than 5 ppm and to provide complete corrosion prevention.
