Optimizing Hydrogen Peroxide Dosing for Odor Control Originating from the Septage Hauler Dumping Area at the City of Kenosha, Wisconsin’s Wastewater Treatment Plant

This paper presents the results of a field study initiated in June of 2017 at the City of Kenosha, Wisconsin, Public Utilities Department, Wastewater Treatment Plant, with USP Technologies implementing hydrogen peroxide (H2O2) as odor control for a septage hauler dumping area. Furthermore, a dual dosing method consisting of hydrogen peroxide dosing at the septage hauler dump site and the grit basin simultaneously was tested in order to control odors in the primary clarifiers. It was found that dosing into both the hauler dump site and grit basin provided the lowest H2S averages at the grit basin and primary clarifier effluent, while using either the same or less hydrogen peroxide than dosing at either location exclusively.
