  • RAISING THE BIOSOLIDS BAR: DEVELOPING AN ENVIRONMENTAL MANAGEMENT SYSTEM

    A California sanitation district’s journey through the process of establishing an EMS for biosolids provides valuable insights, especially for agencies battling public acceptance challenges. THE Orange County, California Sanitation District (District) provides wastewater treatment service for more than 2.2 million people. The facility treats approximately 250 million gallons/day of wastewater and ...


  • The longer-term phytoavailability of biosolids-phosphorus

    Phosphorus based nutrient management could limit biosolids application to rates based on crop fertilizer P recommendations (P-based rates). Determinations of biosolids P phytoavailability relative to inorganic P fertilizers are necessary when P-based rates are mandated. Previous shorter-term (≤4 mo) studies successfully distinguished P phytoavailability differences among biosolids, but the ...

  • An Advanced Biosolids Treatment Process and Potential Beneficial Applications of the Processed Biosolids

    ABSTRACTAn innovative and cost-effective biosolids treatment and processing technology was developed and demonstrated at a pilot and full-scale at the Guelph Wastewater Treatment Plant in Ontario. The Lystek process involves a low but optimized application of heat, alkali, and mixing in a batch or semi-continuous system to achieve the desired physical, chemical and microbiological characteristics ...

  • Oquirrh Mt. Biosolids Composting Facility

    Biosolids Composting at Waste Water Reclamation Facility utilizing the MOR, Inc. Covered Aerated Static Pile (ASP) Composting System.  Facility has eliminated disposal costs associated with land application and landfill by composting biosolids on site and producing at Class A STA approved soil amendment for sale to the public.  The facilty utilizes the MOR, Inc. cover system to reduce ...

  • Rapid Mono-Composting Biosolids Facility

    California Cental Valley composter utilizes the Managed Organic Recycling, Inc. Covered Aerated Static Pile (ASP) Composting System to meet Air Board regulations requireing greated than 90% capture of emissions (VOCs).  System was developed to rapidly compost bisolids to meet PFRP (process to further reduce pathogens) and compost stability in under 10 days.  Facility has increased ...

  • Biosolids Composter Satisfies Customers and Neighbors

    A ticket to Penn State football games isn’t the only hard thing to come by in State College, Pennsylvania. So is the biosolids compost produced by State College’s University Area Joint Authority (UAJA) wastewater treatment plant. “For the last four years, we’ve been sold out before we’ve made the compost,” says Stephen Welch, who manages the UAJA composting plant. All biosolids generated — about ...

  • Managing California’s ever Changing Biosolids Regulatory Climate through the State’s First Design-Build Biosolids Recycling Facility

     ABSTACT In response to regulatory action, the Sacramento Regional County Sanitation District (District) implemented a highly diversified biosolids management program that includes two major elements as well as a number of backup options. The District engaged the private sector for the design, finance, construction, ownership, and 20 year operation and of a Biosolids Recycling Facility ...

  • MSW and Biosolids Become Feedstocks for Ethanol

    The first commercial facility designed to recover recyclables from municipal solid waste, and utilize the residuals with biosolids as feedstock for ethanol production, is moving forward in Middletown, New York. The Orange Recycling and Ethanol Production Facility, to be built on a 22-acre site adjacent to the Middletown Wastewater Treatment Plant, has capacity to process approximately 230,000 ...

  • Can an Agency Maintain a Biosolids Management Program in Another County?

    Local jurisdictions in California are considering banning or restricting biosolids land application in their County because they have no oversight on biosolids being applied and because of public perception and nuisance issues related to biosolids, such as odors and flies. The City of Los Angeles developed a biosolids management program in 1989 and the program continues today. Several different ...

  • A Tale of Three Cities – Different Approaches to Class A Biosolids Management

  • A Comparison of Fluid Bed and Multiple Hearth Biosolids Incineration

    Abstract Incineration has been used as a disposal method for wastewater treatment biosolids for over sixty years. The first multiple hearth furnace for biosolids incineration was built in 1935 in Dearborn, MI. From that time through the late sixties, the multiple hearth was the thermal technique of choice for biosolids disposal. Today there are still some 150-175 aging multiple hearths in ...

  • In-vessel cocomposting of green waste with biosolids and paper waste
