The City of Springfield is seeking a chemical provider to supply odor control chemicals for its sewer collection system and Southwest Wastewater Treatment Plant. The selected provider will be responsible for providing iron salts and hydrogen peroxide to control odors at select locations. The program goals include minimizing odor complaints and controlling hydrogen sulfide levels. The city will monitor specific target levels to evaluate the effectiveness of the odor control program. • The contract will involve the addition of iron salts at the Lone Pine lift station and hydrogen peroxide at the influent junction box located at the SWTP. • The program will also include the treatment of the Wilson Creek gravity interceptor with hydrogen peroxide alone. • The city will monitor dissolved sulfide, vapor H2S, and BOD/Dissolved Phosphorous ratio to ensure the effectiveness of the odor control program.
