    Air purification solutions for corrosion control industry

    Problem: Wastewater processes create gaseous by-products that corrode sensitive electronic components. Wastewater plants are notable for their rotten egg odor, caused by hydrogen sulfide. H2S is highly corrosive to electrical systems and electronics throughout a plant. Factor in aging equipment and infrastructure, and the resultant decrease in uptime, and costly repairs or replacements, harms the bottom line.

    Water Treatment Solutions for Hydrogen Sulfide

    Sulfates and hydrogen sulfide are both common nuisance contaminants. Although neither is usually a significant health hazard, sulfates can have a temporary laxative effect on humans and young livestock. Sulfates also may clog plumbing and stain clothing. Hydrogen sulfide produces an offensive `rotten egg` odor and taste in the water, especially when the water is heated.

    Precision moisture analysis instruments for Hydrogen Sulfide (H2S) monitoring for wastewater treatment

    Control nuisance odors with accurate monitoring. In wastewater treatment, nuisance odors can end up being much more than just a nuisance. Complaints about hydrogen sulfide odors can lead to citations, penalties or worse. Don’t wait for your neighbors to let you know that you have an odor problem; keep on top of hydrogen sulfide odors with a Jerome hydrogen sulfide monitoring solution.

  • 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...

  • Hydrogen Sulfide (H2S) monitoring

    Hydrogen sulfide is the chemical compound with the formula H2S. H2S is colorless, toxic and flammable and is responsible for the foul odour of rotten eggs and flatulence. Hydrogen sulfide often results from sulfur reducing bacteria in nonorganic matter (in the absence of oxygen), such as in swamps and sewers (anaerobic digestion). H2S also occurs in volcanic gases, natural gas and some well waters.

  • Reduced Sulfur Compound Treatment for Refinery Wastewater

    Sulfur compounds, such as hydrogen sulfide, thiosulfates and mercaptans, can present serious refinery wastewater problems. Hydrogen peroxide treatment is a cost effective way to treat these reduced sulfur species. http://www.h2o2.com/industrial/refinery-petrochemical-applications.aspx?pid=98&name=Reduced-Sulfur-Compound-Treatment

  • 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...

  • Chlorine dioxide for municipal wastewater treatment industry

    Wastewater Deodorization: The formation of hydrogen sulfide often poses a problem for municipal wastewater treatment. Chlorine dioxide, a powerful oxidant, can be effectively used to control noxious, irritating, or pungent odors from many operations. Moreover, its unique selective properties permit more efficient application at a lower dosage and cost than chorine, hypochlorite, permanganate peroxide or ozone.

  • Hydrogen sulfide removal in sludge management

    In the treatment of sanitary sewage, bio-solids are separated from the liquid. These bio-solids are concentrated and dewatered using filter presses, centrifuges, or other devices. Hydrogen sulfide and mercaptans are released during the dewatering operation. Carus permanganates react quickly and produce immediate results for hydrogen sulfide removal in order to provide a safe, odor free environment and minimize corrosion due to sulfides.

  • Force Main Systems Sulfide Odor Control with Hydrogen Peroxide

    Force main systems are typically high sulfide odor generators due to septicity conditions related to full pipe flow and a greater anaerobic slime layer (biofilm) thickness. Primary factors that influence sulfide loading generation in a force main include sewage temperature, BOD, retention time, pipe size and flow. Gaseous hydrogen sulfide (H2S) release at the force main discharge is usually the main concern related to odor and corrosion control needs; however, corrosion problems within the pipe can be of a...
