  • How To Handle Chemical Spills & Cleanups

    FAST-ACT is designed for liquid and vapor chemical releases, but the chemicals it attacks does not need to be limited to what we traditionally think of as a chemical spill. Toxic and noxious chemicals can come from a variety of sources such as waste water, decomposition, household chemicals, and animals. Since FAST-ACT can be applied to liquid spill or vapor release enabling Emergency Responders ...

  • Reduction of chlorinous odor by the combination of oxidation and ion-exchange treatments

    To better control chlorinous odor in tap water, we assessed the performance of the combination of oxidation (ozonation or advanced oxidation processes, AOP) and ion-exchange treatment. In this process, the hydrophilic neutral fraction (a major dissolved organic matter (DOM) fraction) is converted to ionic species, and these ions and ammonium ion are effectively removed during ion-exchange ...

  • Intensive odor - Case Study

    Example: Waste disposal for tanneries Similar tasks: Leather industry, fish cannery, bio-ethanol production, coffee roasters Various leather producers operating a tannery founded a joint waste disposal company which produces valuable proteins from the waste. The refining of the raw material and the treatment with ammoniac compounds produces malodorous waste gases. As these contaminants ...

  • Biotreatment of Organic and Inorganic Odors

    Air emissions from manufacturing operations and waste treatment plants often consist of a combination of odors and volatile chemicals. Odors are inorganic or organic compounds, which are present in low concentrations, typically 20 ppmv or less, which have an unpleasant odor. Volatile chemicals are often present at higher concentrations than odors, but may or may not have any odors associated with ...

  • Hydroxyl-Radical Odor Control

    In-Pipe now offers the IPTC(OH-), a hydroxyl radical based odor control option for Lift Stations and WWTP headworks that requires no chemicals, needs only a small footprint and uses minimal electrical power. The IPTC(OH-) chemical free scrubber system connects to the existing lift station vent to oxidize hydrogen sulfide outside of the lift station environment in order to scrub odors before ...

  • Smart Series-Odor Management

    Tackling odors at composting facilities is a manageable task made simpler by inventorying and treating all sources and tapping into technology advances. Perhaps one of the most difficult realities that had to be faced 15 to 20 years ago by the composting universe is that the phrase, “odor-free” - at least when it comes to composting - is probably an oxymoron. Feedstocks that biodegrade within the ...

  • Reducing Odor and VOC Emissions

    The Montgomery County Regional Composting Facility (MCRCF) in Silver Spring, Maryland is designed to process 400 wet tons/day of lime amended biosolids from the Blue Plains Wastewater Treatment Plant (WWTP) in Washington, D.C. Recently, political pressures forced operations to cease at the MCRCF. Although the aerated static pile composting plant’s fate has not been completely decided, its owner, ...

  • Mercaptan odor control - case study

    Background In municipal and industrial waste treatment, hydrogen sulfide is not the only offensive gas generated from anaerobic decomposition. Mercaptans (RSH) are the organic equivalent to hydrogen sulfide and more odorous at 1/1000th the concentration. Mercaptans are naturally occurring from the degradation of sulfur containing organics (proteins, etc.).   A table of ...

  • Design, Construction, Installation, and Operation of a Compact Bio-Oxidation System to Manage Odors at the City of Wilsonville WWTP

    ABSTRACTThe 5 mgd Wilsonville WWTP was experiencing odor complaints from the adjacent residential neighborhood. An existing in-ground, bark and wood-chip biofilter was not performing well. In December 2004, the City of Wilsonville contacted BioReaction Industries (BRI) requesting the design of a bio-oxidation system with guaranteed performance criteria. The project required an understanding of ...

  • Diesel Oxidation Catalyst for Locomotive

    Description A tourist touring train in Skagway, Alaska, powered by a 6 cylinder, 900 hp, Alco 251B diesel locomotive. The train carries tourists through a scenic mountain area. Challenge Diesel odor and soot from the diesel locomotive was a nuisance to passengers on the train. DCL was approached for an emission control solution. Solution DCL custom designed an ...

  • An odor predictive model for Rendering applications

    Abstract The rendering process consists of crushing and heating animal remains to produce by-products. The U.S. produces approximately 30 billion pounds of inedible animal by-products annually, exporting a market value of US$ 1.5 billion. Benefits of the rendering process include reducing total waste material, and helping the livestock industry stay competitive over vegetable protein ...

  • 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 ...

  • Understand the Capabilities of Bio-Oxidation

    Biological air-pollution control technology* has been used extensively in Europe for decades and, to a lesser extent, in North America for the past two decades. Most installations in the U.S. have been on air-emission vent streams that were not subject to numerical limits (i.e., ...

  • Case study - Meat processing odor control

    Overview For its first two years of production, a food manufacturer based in South Wales, England, focused its production on potatoes. Neighborhood residents voiced no complaints about odors during this time period. However, as new production lines (including barbequed meats and curried chicken) were added, the complaints began, and it became clear that odor abatement equipment was needed ...

  • Biotreatment of Odors from the Zimpro Sludge Conditioning Process

    Management of odor emissions generated during thermal sludge conditioning is a well known disadvantage of the “Zimpro” process. Traditional methods of using chemical oxidation and high temperature destruction result in the formation of secondary products, such as chlorine gas, organic halocarbons or nitrogen oxides. In this study, biotrickling filter technology was evaluated at the Villa Hills ...
