  • Innovative Ammonia Control - Case study

    Ammonia has increasingly become more of a regulatory concern. Ammonia emissions into the atmosphere have been linked to the formation of fine particulate matter, while ammonia emissions in wastewater are restricted because of the negative affect the chemical has on rivers, lake, and aquifers. Many sources of biofuels contain ammonia or can create ammonia during processing. The following case ...

  • Chemical Engineering Magazine: Odor Issues and Solutions for Wastewater Treatment

    Today, there has been a dramatic increase in the number of industrial operations that are located within or near small towns and even large cities. When local residents constantly smell these industrial processes – particularly from wastewater treatment — unhappy neighborhoods are generally the result. In addition, many wastewater facilities can no longer produce odors without facing ...

  • 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, ...

  • Ammonia Stripping And Integrated Fixed-Film Activated Sludge

    The Keystone Sanitary Landfill (KSL) is located at the Keystone Industrial Park in Dunmore and Throop Boroughs, Pennsylvania. The 618 acre landfill site was originally permitted for 5,000 tons of trash per day, and recently received a permit to develop more cells to extend the operation for another 25 years at 5,000 tons per day. Landfill leachate, an inevitable by-product of landfilling, is ...


  • 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 ...

  • Comprehensive Odor Emissions Study Hall Street Wastewater Treatment Plant Concord, New Hampshire

    ABSTRACTThe operation of the Hall Street wastewater treatment plant (WWTP) in Concord, NH has caused the emission of objectionable odors from various liquid and solids treatment processes resulting in periodic odor complaints from its neighbors. The City of Concord retained Fay, Spofford & Thorndike (FST) to conduct a comprehensive odor emissions study at the Hall Street WWTP and to recommend ...

  • Comparison of different measurement methods of odour and odorants used in the odour impact assessment of wastewater treatment plants in Poland

    The aim of this study was to compare sensory and analytical methods used to measure odour and odorants concentrations for odour impact assessment on municipal wastewater treatment plants (WWTPs). A range of sources and odour or odorants concentrations were used to compare the methods. Four different odours and odorants measurement methods were compared: field olfactometry using Nasal Ranger® ...

  • Feasibility of a flow-through treatment regime by the EOH2O™ electrolytic oxidation process to meet BOD, TSS and ammonia discharge limits from municipal facultative wastewater lagoons

    The patented EOH2O electrolytic oxidation process has been employed as a continuous batch treatment system for reduction of nutrients, TSS, odor, and pathogens in manure lagoons for several years. Due to the positive results of such applications, several Pacific Coast rural municipalities approached Aquatic Technologies to determine if a constant flow-through treatment system could be designed to ...


  • Dispersion Modeling as a Tool to Establish Odor Policy

    Odor control is a critical component of the Orange County Sanitation District’s (the Sanitation District) planning and operations. The Sanitation District’s two wastewater treatment plants (Fountain Valley, CA and Huntington Beach, CA) were isolated when originally constructed in the middle of the 20th century, but are now surrounded by high-density residential areas as well as highly used ...

  • How NoMonia Works to Treat or Remove Your Ammonia - Case study

    Most water utilities should have effective treatment methods for the filtration of arsenic, iron and manganese from drinking water sources. However, as ammonia becomes increasingly concentrated in groundwater throughout the U.S., many utilities around the country are searching for ways to successfully treat the contaminant, while also meeting U.S. Environmental ...

  • Impact of Lime Dose and Mixing Quality on Odor Generation by Lime-Stabilized Biosolids

    ABSTRACTOdor generated from lime-stabilized biosolids with various lime doses and mixing regimes was studied during two bench scale experiments over four weeks of storage to determine the correlation between the lime stabilization process and odor strength. For the first bench scale experiment, dewatered solids were mixed with various lime doses (4.5% and 11.7% by wet weight) under various mixing ...

  • Home, Sweet Wastewater Building

    How can a wastewater treatment plant embedded into a neighborhood not use much landmass and be environmentally friendly and user-friendly all at the same time? One system aims to do all of the above. Why should a wastewater treatment plant always have to look like, well, a wastewater treatment plant?  A visual trip through project files of Aqueonics Inc., based in Greenville, SC, reveals photos ...
