hydrogen sulfide control plant Applications

  • Gravity Main Sulfide Odor Control with Hydrogen Peroxide

    Gravity main sewer systems include major trunk lines and the tributaries that feed them. Hydrogen sulfide (H2S) odor builds up in the collections system as the flows collect from upstream reaches and become larger, deeper and more septic (oxygen depleted) in the downstream reaches more near to the wastewater treatment plant. In general, most of the more significant hydrogen sulfide odor and corrosion control problems occur in the major trunk systems segments conveying flow to the plant. Therefore, selection...

  • Sulfide Oxidation with Hydrogen Peroxide (H2O2)

    Sulfide Odor Control Sulfide is found throughout the environment as a result of both natural and industrial processes. Most sulfide found in nature was produced biologically (under anaerobic conditions) and occurs as free hydrogen sulfide (H2S) - characterized by its rotten egg odor. We are most likely to encounter biogenic H2S in sour groundwaters, swamps and marshes, natural gas deposits, and sewage collection/treatment systems. Manmade sources of H2S typically occur as a result of natural materials containing...

  • Filamentous Bulking Control with Hydrogen Peroxide

    Basis of Control with Hydrogen Peroxide Hydrogen peroxide may be used to correct a serious filamentous bulking situation or, preferably, to prevent one from occurring until adjustments can be made to remove the cause. When applied to the return activated sludge, hydrogen peroxide supplies dissolved oxygen which helps restore the microbial activity necessary for effective operation, while selectively oxidizing the filaments which retard settling. The effective dose of hydrogen peroxide is a function of time and...

  • Headworks Odor and Corrosion Control Using Hydrogen Peroxide

    Hydrogen Peroxide typically controls odors and corrosion at treatment plant headworks by direct oxidation of hydrogen sulfide (H2S) within the wastewater. 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...
