Hydrogen Peroxide

Hydrogen Peroxide

Hydrogen Peroxide typically controls odors and corrosion in wastewater by direct oxidation of hydrogen sulfide (H2S). In the direct oxidation mode, H2O2 is applied to the wastewater 5-30 minutes prior to the point where the odors are being released, generally as the wastewater line enters the plant boundary. The efficiency of hydrogen peroxide treatment depends upon the available reaction time, the level of iron in the wastewater (reaction catalyst), wastewater pH and temperature, and the initial and target levels of H2S odor. Under optimal conditions, effective dose ratios are 1.2 – 1.5 parts H2O2 per part dissolved sulfide, and can be reliably estimated through beaker tests. In contrast to nitrate, hydrogen peroxide can be used reliably within a treatment plant to control odors in the headworks, primary treatment, and solids facilities. Additionally, H2O2 can be utilized as a supplemental source of oxygen either in the collection system or treatment plant.
