  • Reduction of odor and odorant emissions from slurry stores by means of straw covers

    Swine (Sus scrofa) slurry stored in open storages is a source of airborne contaminants. A customary practice for ammonia and odor control consists of covering the surface of the slurry with floating materials, such as straw. Although straw covers have been proven to generally reduce gaseous emissions, more knowledge is needed regarding how age, moisture content, and microbiological development of ...

  • Application of Biotrickling Filter for Odor Control at The Morris Forman Wastewater Treatment Plant

    Pilot-scale study of a biotrickling filter using synthetic, high surface area media was undertaken by MSD Louisville, with the intention of saving the high cost of operating thermal oxidizers. Currently, two recuperative thermal oxidizers are used to treat odorous emissions from various sources. The pilot study showed that it is possible to treat hydrogen sulfide and organic sulfur compounds at ...

  • 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 ...

  • Control of biosolids cake odors using the new biosolids odor reduction selector process

    ABSTRACT Recent introduction of more efficient dewatering devices that generate higher solids concentrations in dewatered cake has been plagued with the non-desirable side effect of more odorous dewatered biosolids. Previous research has shown that the production of volatile organic sulfur compounds (VOSC’s) such as methanethiol (MT), dimethyl sulfide (DMS), and dimethyl disulfide (DMDS) ...

  • Advancing Odor Control to New Levels Gurnee Sewage Treament Plant North Shore Sanitary District

    ABSTRACTThe North Shore Sanitary District (District) owns and operates a 24-mgd sewage treatment plant located in Gurnee, Illinois. Frequently, odors from the two-stage activated sludge plant’s solids handling facilities made their way into the adjacent residential neighborhood. A new two-stage odor control system for the plant’s solids handling facility was put on-line in October 1999. This ...

  • Managing Ponds for BOD Reduction and Odor Control

    A large number of food processors utilize ponds to treat their wastewater. Most of the time these ponds are aerobic in which they use oxygen to degrade the wastewater biological oxygen demand (BOD). Fruit and vegetables contain a high amount of simple sugars and other organic compounds that when exposed to water are released into the water stream. These organic compounds require oxygen to degrade ...

  • Southeast Georgia sewage treatment

    Problem: A WWTP in Southeast Georgia located on a resort island has a 3 million gallon per day flow. The WWTP was experiencing major odor problems at the head of the plant, as well as poor digestion and settling of bio-solids in the SBR’s and aerobic digesters. The odors were primarily H2S and were the source of numerous complaints from the residents living in the vicinity of the WWTP. The plant ...

  • Case study of odor and indoor air quality assessment in the dewatering building at the Stickney Water Reclamation Plant

    Indoor air quality (IAQ) and odors were determined using sampling/monitoring, measurement, and modeling methods in a large dewatering building at a very large water reclamation plant. The ultimate goal was to determine control strategies to reduce the sensory impacts on the workforce and achieve odor reduction within the building. Study approaches included: (1) investigation of air mixing by ...

  • Real-time monitoring and forecasting of odor after dewatering in wastewater treatment

    A real-time odor monitoring system was developed to evaluate and predict odors levels of dewatered solids generated by the District of Columbia Water and Sewer Authority’s (DCWASA) advanced 370 mgd wastewater treatment plant (WWTP) in Washington, DC. Each year, DCWASA generates over 400,000 wet tons of biosolids and recycles these biosolids by applying them to over 20,000 acres of agricultural ...

  • 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 ...

  • Full-scale field trials identify sulfate discharge limits for municipal wastewater odor and corrosion control

    ABSTRACT The Massachusetts Water Resources Authority (MWRA) owns and operates one of the largest wastewater collection and treatment systems in the U.S. serving 45 member communities and operating the 1.2 billion gallon-per-day Deer Island Wastewater Treatment Plant in Boston Harbor. The MWRA has very few odor and corrosion problems so it was unusual when the MWRA encountered a high ...
