  • Biosolids- Considering the Types, Applications and Biosolids Drying Methods

    While some water treatment plants are meant to simply make the sludge safe enough to dispose of, most facilities continue to treat the sludge so that the material can be put to good use in their communities. Once sludge is treated and processed to meet EPA safety standards for productive use, the resulting nutrient-rich organic material is termed as biosolids. ...

  • Pyrobustor for the thermal treatment of biosolids

    ARA Pustertal AG operates the Tobler wastewater treatment plant in South Tyrol, Italy. The Tobler ARA facility is the fi rst and only water treatment plant in Central Europe that is housed in an underground cavern. The impressive cavern plant, whose tunnels are twice as large as that of a highway tunnel, began operation in July, 1996. The inclusion of a sludge drying plant and a thermal sludge ...

  • Texas composter grows with biosolids

    New Earth Compost and Soils — with facilities in San Antonio and Conroe, Texas — was born 15 years ago out of a local meat packing plant’s long-standing need to dispose of manure from its operation (see “Composting Integrated Into Family Business,” October 2009). It soon became evident that scores of other businesses in and around the San Antonio area, where the ...

  • Small-Scale Biosolids Composting

    Cambridge, Ohio retrofitted a portion of its vacuum assisted drying beds into a covered composting facility, processing about 300 dry tons/year of biosolids and wood chips. Like many small communities in an agricultural area, the City of Cambridge, Ohio (pop. 14,000) managed biosolids generated by its 2.25 mgd Water Pollution Control Center (WPCC) via land application on farm fields. “Then ...

  • 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 ...

  • 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 ...

  • Chemical and toxicological assessment of a full‐scale biosolid compost

    The impact of a full‐scale biosolid composting plant on the fate of a broad range of priority organic pollutants was investigated. Chemical analysis was performed at different steps of the process during two seasons. Simultaneously, the toxicological quality was assessed using estrogen α‐, dioxin‐, and pregnane X‐receptor reporter cell lines. Mass‐balance calculation highlighted the removal of ...

  • Biosolids Applied to Land: Advancing Standards and Practices

    Summary Wastewater treatment in the United States is a major cornerstone of efforts to keep the nation’s waters clean. Sewage sludge is the solid, semisolid, or liquid residue generated during treatment of domestic sewage. Since the early 1970s, the U.S. Environmental Protection Agency (EPA) and the wastewater treatment industry have promoted recycling of sewage sludge. With the prohibition of ...


  • Biosolids Heat Drying: Safety in Design and Owner Operation

    ABSTRACTInterest continues to grow in heat drying as a means of processing biosolids into an aesthetically pleasing product form with multiple use opportunities, while also achieving a significant reduction in both volume and weight of biosolids for off-site hauling. As the number of heat drying installations increase, so too do reports of safety incidents—an indication that Owners and facility ...

  • Pyrobustor - A Proven,Small-Scale, Biosolids-to-Energy Solution

    27 municipalities in southern Germany set up a special-purpose entity called KSV GmbH for the specific purpose of disposing regional sewage sludge. The goals of this project were two-fold; eliminate the expensive cost of transporting sewage sludge over long distances and avoid incalculable costs by outsourcing sludge disposal. To achieve this, KSV GmbH installed the Pyrobustor® at the ...

  • Trends in biosolids handling technologies: economics and environmental factors

    Changes in activated sludge technology, with a much greater focus on nutrient removal instead of removal of organics, together with relatively long sludge mean that the primary sludge stream has been lost, and the sludge produced is less degradable. At the same time with the growing importance of sustainable solutions, beneficial agricultural use is being increasingly used. This changes quality ...

  • Biogeochemical response of a northeastern forest ecosystem to biosolids amendments

    Received for publication September 22, 2007. In the northeastern United States interest in the use of biosolids on forest lands is growing due to the prevalence of extensive forests and market incentives for waste disposal, yet much of the regulatory framework for biosolids land application is based on agronomic practice. This study evaluated the response of soils in a young (~20 yr old) ...

  • Biocycle Nationwide Survey: The State of Biosolids in America

     The State of Biosolids in America TAKING the pulse of biosolids management practices in the United States yields a combination of hard data and valuable insights. Between survey responses and telephone conversations, state biosolids coordinators around the country paint an overall picture of progress with the beneficial use of biosolids, along with a dose of reality about political, ...
