  • Why Air Quality Specialists Should Measure for Sulfur Dioxide (SO2) in Homes & Offices - Case study

    What is Sulfur Dioxide? (SO2) Sulfur Dioxide (SO2) is a highly reactive gas that is part of a larger group of sulfur oxides or SOx gases. According to the U.S. Environmental Protection Agency, the largest sources of SO2 emissions are due to “fossil fuel combustion at power plants (73%) and other industrial facilities ...

  • Comparison of particulate pyrite autotrophic denitrification (PPAD) and sulfur oxidizing denitrification (SOD) for treatment of nitrified wastewater

    The use of reduced sulfur compounds as electron donors for biological denitrification has the potential to reduce chemical and sludge disposal costs as well as carry-over of organic carbon to the effluent that often occurs with heterotrophic denitrification. Although a number of prior studies have evaluated sulfur oxidizing denitrification (SOD), no prior studies have evaluated particulate ...

  • Control of malodors using Ecosorb - A natural product

    Abstract Ecosorb removes many malodors, including sulfur dioxide, hydrogen sulfide and ammonia, from the environment. It is made up of a combination of essential oils consisting of an equilibrium of neutral organic compounds and organic buffers. Its pH ranges from 4.0 to 6.8. Acidic malodors such as hydrogen sulfide and sulfur dioxide are removed by at least four mechanisms ...

  • Thermal dissolution of Shengli lignite in ethyl acetate

    Thermal dissolution (TD) of Shengli lignite (SL) in ethyl acetate (EA) was carried out under different conditions, including temperature, solvent to SL ratio (RS/SL), and time. The yields of EA–extractable fractions (EAEFs) increased with raising temperature from 240–300°C, but then decreased when the temperature was higher than 300°C, and the effects of RS/SL and time on EAEF yields was slight ...

  • Industrial Sources Influence Air Concentrations of Hydrogen Sulfide and Sulfur Dioxide in Rural Areas of Western Canada

    A survey of monthly average concentrations of sulfur dioxide (SO2) and hydrogen sulfide (H2S) at rural locations in western Canada (provinces of Alberta, British Columbia, and Saskatchewan) was conducted in 2001– 2002, as part of an epidemiological study of the effects of oil and gas industry emissions on the health of cattle. Repeated measurements were obtained at some months and locations. We ...

  • The Light at the End of the Tunnel - How to Successfully Operate a UV Disinfection System

    ABSTRACTOver the past ten years, ultraviolet (UV) technology has become a commonly applied method of disinfecting of wastewater effluent. UV disinfection involves passing wastewater effluent through a confined chamber with rows of underwater lamps emitting UV energy. Viruses and bacteria become inactivated upon exposure to dosages of UV energy, thereby disinfecting the wastewater. The UV system ...

  • Investigation of High BOD in Final Plant Effluent

    The Detroit WWTP had experienced intermittent high BOD in the dechlorinated final plant effluent from September 2003 to October 2004 and was not related to wet weather events. No NPDES violations occurred. A short-term cost effective laboratory investigation was initiated during the months that the intermittent high BOD values were occurring to determine possible causes. The results of the ...

  • H2S Oxidation and Sulfur Recovery

    Lubrizol’s facility in LeHarve, France produces a lube oil additive via a batch reaction that uses elemental sulfur as a reactant and produces H2S as a byproduct. Lubrizol selected Gas Technology Products LO-CAT® II Hydrogen Sulfide Oxidation Process to sweeten H2S emissions and recover sulfur. The LO-CAT II system was chosen for its ability to handle the process variation in H2S ...

  • The Effects of AXI AFC-705 on SOX

    The treatment of carbon based fuels with AFC-705 has a significant effect on trace sulfur combustion chemistry. In diesel engines, gasoline engines and open flame applications (boilers) the use of AFC-705 treated fuel will significantly reduce sulfur oxide (SOX) emissions, and related sulfur acid corrosion ...

  • Analysis of Natural Gas Products by GC / TCD / FID

    The complex mixture of condensible hydrocarbons and permanent gases in a natural gas product has historically been separated on gas chromatographs equipped with dual columns and a switching valve. The light gases are separated from heavier compounds on a molecular sieve column, which is then backflushed onto a suitable column to separating the rest of the mixture. The Buck Scientific Model 910 ...

  • Biogeochemistry of an Iron-Rich Hypersaline Microbial Mat (Camargue, France)

    In situ microsensor measurements were combined with biogeochemical methods to determine oxygen, sulfur, and carbon cycling in microbial mats growing in a solar saltern (Salin-de-Giraud, France). Sulfate reduction rates closely followed the daily temperature changes and were highest during the day at 25°C and lowest during the night at 11°C, most probably fueled by direct substrate interactions ...

  • Electrochemical oxidation of sulfite ions in aqueous solutions

    Gaseous pollutants that affect human health, destroy vegetation and damage materials and art treasures can be converted into harmless components by electrochemical reactions. Electrochemical gas purification methods can be applied basically in two steps. In the first step, gases to be removed are absorbed in an aqueous electrolyte. Then, in the second step, they can be converted into harmless ...

  • Solidification/Stabilization

    Introduction: As for in situ solidification/stabilization (S/S), ex situ S/S contaminants are physically bound or enclosed within a stabilized mass (solidification), or chemical reactions are induced between the stabilizing agent and contaminants to reduce their mobility (stabilization). Ex situ S/S, however, typically requires disposal of the resultant materials. Under CERCLA material can be ...
