  • 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, ...

  • 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 ...

  • 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 ...

  • Selection of Bioreactor Media for Odor Control

    The support media is one of the most critical elements of a biofiltration system. In this chapter, biofilters and biotrickling filters will be referred to as “biofilter”, and this distinction will be discussed later in this chapter. The support media’s main function is to provide contact between the gas-phase contaminants and active microbial cultures either immobilized within and/or attached as ...

  • 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 ...

  • Advanced Enviro - Septic™ Wastewater Treatment System Septic Tank Effluent Filters and Charco al (Odor) Filters NOT Recommended

    Abstract: Effluent filters are installed in the outlet from the septic tank with the intended purpose of retaining solids inside the tank, preventing them from entering the treatment system and/or dispersal field. The concern is that if solids escape from the septic tank, they could cause clogging of the system components or the soil interface. While this may be a legitimate concern for some ...

  • 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 ...

  • Elimination of NH3 and odor from composting by biotrickling filter and preliminary exploration on molecular biology

    A biotrickling filter was focused on treatment of odorous NH3 gas, along with volatile organic compounds (VOCs) and other odorous gases during cattle manure composting. The biotrickling filter could treat NH3, the main composition, with removal efficiencies of close to 100% because NH4+ was bio-oxidized in the biofilm to NO3− resulting final NO3− concentrations of about 1000 mg/L. Results of ...

  • Treating Taste & Odor and Disinfecting Drinking Water with UV

    Cornwall is a city of nearly 60,000 people in Ontario, Canada. It is located on the St. Lawrence River, approximately 1,700 km from the Atlantic Ocean and 2,000 km from Lake Ontario. The city draws its drinking water from the St. Lawrence, a reliable and generally good-quality source. However, in the late summer and early fall, dying algae from algae blooms during the warmest months often ...

  • Controlling Odors from Waste Water Treatment Plants

    INTRODUCTION In recent years, there is growing public awareness of odors from waste water treatment plants, which mainly stems from the following observed trends: The public is less tolerant of objectionable odors from waste water treatment plants; Many waste water treatment plants have seen residential, commercial, or other developments established near the facility ...

  • Pilot-Scale Biofilter Test for Treating Zimpro Odors

    The thermal sludge conditioning process of U.S. Filter/Zimpro Corporation, Rothschild, Wisconsin (Zimpro process) is primarily used to improve dewatering characteristics of the waste sludge. The process entails a partial breakdown through oxidation and hydrolysis of complex, high molecular weight organic compounds, such as, proteins, fibers, carbohydrates, and fats. The partial breakdown of ...

  • 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 ...

  • Challenges in Designing an Odor Control System to Make a 32 mgd WWTP Odor Free

    INTRODUCTIONCity of Bakersfield located in Kern County, CA, is carrying out a major expansion to one of its wastewater treatment plants called Plant 3. Currently, Plant 3 treats about 15 mgd of wastewater flow with a design capacity of 16 mgd, on an Annual Average Dry Weather Flow (AADWF) basis. The current expansion will take the existing plant to an AADWF capacity of 32 mgd. As part of the ...

  • Combination filters

    Simply defined, a combination filter is one that does at least one other processing job at the same time as filtering a suspension. The classic example, of course, is the packed bed of activated charcoal, which acts as a remover of chemical impurities from the suspension, as well as removing dust particles - although this is actually not a very good example, because it is primarily an adsorber, ...

  • WEF/A&WMA Odors And Air Pollutants Conference March, 2010

    Abstract The application of biotrickling filters (BTF) has become commonplace for the removal of hydrogen sulfide and for the reduction of odors from air emissions in wastewater treatment facilities. Operation at a low pH of 1.5-2.0 provides an environment for rapid reproduction of thiooxidans bacteria and metabolism of hydrogen sulfide (H2S). An elimination capacity in excess of 90 gm of ...
