odor control additive Applications

  • 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 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. H2O2 + H2S → S0 + 2H2O Frequently, control of odors through the primary clarifiers is wanted. In such case, the mechanism of control is both direct oxidation of H2S (as it rises from the solids blanket), and prevention of odor generation (by supplying dissolved oxygen). Control is typically achieved with a booster dose of 1-2 mg/L H2O2 added to the clarifier influent. Higher doses or alternate modes of addition may be required in cases where: 1) hydraulic retention times are > 2-3 hours; 2) solids blanket depths are > 1-2 feet; 3) soluble BOD levels are > 200-300 mg/L; or 4) waste activated sludge is co-settled with the primary solids. 2H2O2 → O2 + 2H2O

  • Mold Control

    Controlling mold spores and bio-contaminants is a challenge for indoor gardeners that requires attention to detail and specialized equipment. An average cubic foot of air has around 100,000 mold spores. When sufficient moisture is available, mold grows. AgriAir Purifiers control and eliminate Aspergillus and many other types of spores, mildew, odors, and VOC as well as sanitize the air and hard surfaces from biological contaminants generated by organic decay during the entire growing process. AgriAir Purifiers generate ionized-hydro-peroxides, which result in a proactive method of indoor air sanitation and promote organic garden production. This purification method eliminates the need for the use of additional chemicals or biocides that generally contain toxic compounds. AgriAir products can safely be used in occupied spaces throughout the entire grow cycle all while effectively destroying mold spores and other harmful bio-contaminants.
