  • Microbial control reduces sulfide

    The article is about sewage odour control using a totally NEW technology known as Microbial Control. Microbial control treats the cause of sewage odour, corrosion and methane gas production in sewers by removing the biofilm / sediment (slimes) complexes where sewage odour and methane gas are produced. Without sewage odour you cannot have sewage infrastructure corrosion from sulfuric acid. As ...

  • Analyzing sulfur in soil and sediment with handheld XRF

    Background Sulfur creates more than nasty odors. Exposure to low levels (0-10ppm) of hydrogen sulfide (H2S) causes irritation of eyes, nose, and throat; higher levels can cause headaches, dizziness, nausea and vomiting, coughing, and breathing difficulty. H2S and numerous other odor-causing compounds are generated as a result of organic material decomposition. In the case of the Muddy River in ...

  • SULFURIC ACID PLANT TAIL GAS CLEANUP WITH CANSOLV“ SYSTEM SO2 SCRUBBING TECHNOLOGY

    The tail gas from a single absorption sulfuric acid plant typically contains 2000-3000 ppmv of unreacted SO2. Emission regulations for new plants in most jurisdictions today require cleanup of this stream prior to discharge into the atmosphere and many grandfathered units are being required to decrease emission levels. The current paradigm is to add a second stage of conversion, which reduces the ...

  • Sewer Collection System Bioaugmentation Reduces Influent Load and Improves Plant Performance

    Abstract The effectiveness of In-Pipe Technology (IPT) patented sewer collection system engineered bioaugmentation on i) influent wastewater loads to wastewater treatment plant (WWTP), ii) WWTP performance, and iii) effluent quality, was a demonstrated at a domestic sequencing batch reactor (SBR) WWTP (Sewer District #20) in Suffolk County, Long Island, New York in collaboration with the ...

  • Environmental monitoring solutions - Total solution for measuring benzene in gasoline – Case Study

    EPA rule 40 CFR Parts 59, 80, 85, 86 (Control of Hazardous Air Pollutants From Mobile Sources) is about to reduce allowable emissions of benzene and other mobile source air toxics. It originally went into effect on April 27, 2007, with a recent Final Release on October 8, 2008. On January 1, 2011, the rule limits the benzene content of reformulated gasoline (RFG) and conventional gasoline (CG) ...

  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • EPA establishes new 1-hour standard for sulfur dioxide

    On June 2, 2010, the U.S. EPA established a new 1-hour primary National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO2). The new 1-hour standard was set at the level of 75 parts per billion (ppb) calculated as the three-year average of the 99th percentile of the annual distribution of daily maximum 1-hour average concentrations. With the establishment of the new 1-hour SO2 standard, ...

  • The Effect of Digester Temperature on the Production of Volatile Organic Sulfur Compounds Associated with Thermophilic Anaerobic Biosolids

    ABSTRACTVolatile organic sulfur compounds (VOSC) are recognized as major contributors to malodors associated with dewatered and land applied biosolids. Recent research in the area of VOSC production and control has revealed that microbial degradation of sulfur containing amino acids is the likely mechanism in the formation of hydrogen sulfide (H2S) and methanethiol (MT). The objective of this ...

  • Biological process for H2S removal form gas streams the Shell-Paques/Thiopaq gas desulfurization process

    On 12 September 2002 natural gas containing H2S was introduced to the first high-pressure Shell-Paques unit at Bantry, east of Calgary in Canada. H2S in the sweet gas is guaranteed to be 4 ppmv, while the total design amount of sulfur to be removed per day is approximately 1 ton. The start up was organized in such a way that the specification on H2S in the sweet gas was met immediately and ...

  • Chemical and Biological Treatability Testing of an Industrial Leachate

    Remediation efforts are ongoing at the Avtex Fibers Superfund Site in Front Royal, Virginia. As part of the future remediation of several surface impoundments used for viscose waste disposal during plant operation, it may be necessary to extract contaminated leachate and groundwater for ex-situ treatment and discharge to the Shenandoah River. This waste stream contains high concentrations of ...

  • Odor Control Advances at Composting Facility

    The Rockland County (New York) Cocomposting Facility began operations in February, 1999, processing biosolids from the five publicly owned treatment works (POTWs) in the county. The Rockland County Solid Waste Management Authority (RCSWMA) owns the facility, but contracted with Waste Management of New York to design, build and operate (DBO) the 110 wet tons/day agitated bin composting facility ...
