  • 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 ...

  • 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 ...

  • Principles and Practice · Quick-to-Implement Odor Reduction Techniques

    The city of close to one million has already exceeded its 50 percent recycling rate as it prepares to launch a new organics curbside collection program in 2002. SAN JOSE, California recently hit — and exceeded — its 50 percent landfill diversion goal, due in large part to the yard trimmings collection program for its 930,000 residents. The city in the heart of the digital divide has submitted a ...

  • 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) ...

  • 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 ...

  • 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, ...

  • A combined process of non-thermal plasma with sludge stabilization for the simultaneous reduction of odor and organic waste

    Odor emissions and sludge disposals have become most challenging issues in many sludge treatment plants, and separate chemical oxidation processes have been commonly employed for these problems. It is, therefore, necessary to develop a combined process that simultaneously reduces the odor emissions and the amount of waste sludge. In this study, a non-thermal plasma reactor using a dielectric ...

  • Case Study - Georgia wastewater utility credits Ecosorb for significant reduction in odor complaints.

    The Douglasville-Douglas County Water and Sewer Authority (WSA) has been delivering quality water and wastewater service to more than 90,000 Douglas County residents for over 17 years. WSA’s slogan “Award-Winning Service For Our Local Community,” proves to be much more than just advertising jargon. Over the past 17 years, their honors have included three citations from the U.S. ...

  • 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 ...

  • 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 ...

  • Treatment of unpleasant odors in municipal wastewater treatment plants

    The purpose of this paper to present a case study on how to address the odor problem from secondary sources within a municipal wastewater treatment plant (WWTP) by first identifying the locations of the problem and second by evaluating alternative treatment technologies. The WWTP of Chania is a typical 100,000 equivalent inhabitants-facility in a warm semi-arid environment which is located close ...

    Utah Valley Daily Herald Article on the benifits on using micro-pore membrane compost covers when composting highly odorus material.  In February of 2009 Utah Valley's North Sewer Distirict conducted a pilot study to determine the effectivness of mirco-pore membrane compost covers in reducing odors from biosolids (sewage sludge) composting.  Odor testing was conducted over a term of one ...

  • Wastewater-Solids Dewatering Odor Control - Case Study

    Background The Milan Wastewater Treatment Plant, located just south of Moline, Illinois, is a 1.7 MGD (6,434 m3/day) activated sludge facility with an average wastewater flow of 700,000 gpd to 800,000 gpd. This facility dewaters primary sludge using a belt filter press (Figure 1). The press operates an average of three times per month, 8 hours per day at a pump rate of 100 gpm. The ...

  • Odor issues at Mariposa MSW composting facility

    The Mariposa County MSW composting facility was built at the county landfill to remove some dry recyclables from the waste stream and to produce compost for daily cover. One key motivation was to increase the lifespan of the landfill and to postpone a costly long-haul. The facility was permitted, designed and built by a team of engineers and vendors. It began operation in the summer of 2006. ECS ...
