  • Biosolids Recycling: An Assessment of Public Perception and Knowledge

    A descriptive-correlational study was conducted in a four county metropolitan area in the southeast United States (U.S.) to determine attitudes and knowledge about biosolids recycling. Eight biosolids land application site options (farmlands, grazing lands, public parks, highway medians, home gardens, lawns, forest lands, and use as mulch after composting) were assessed by each of the 303 ...

  • Biosolids Program Reliability through California’s First Design-Build Biosolids Recycling Facility

    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.

  • Biosolids ban struck down

    In 1994, Los Angeles County Sanitation Districts (LACSD) bought a 4,700-acre farm (called Green Acres Farm) in southwest Kern County for the purpose of land applying biosolids from its 11 wastewater treatment plants. LACSD land applied 800 wet tons/day at this site for several years. In 2006, Kern County voters passed Measure E on the ballot with 83 percent approval. This measure banned ...

  • Philadelphia Recycling Center case study

    The Challenge An arm of the City of Philadelphia Water Department, the Biosolids Recycling Center (BRC) was in need of critical support. Consisting of a dewatering complex and a compost operation that utilized a portion of the dewatered biosolids (with the balance transported offsite for disposal), the BRC had an expired Title V air management operating permit and was at risk of regulatory ...

  • 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 ...

  • Biosolids Odor Prediction Models: Sensory and Analytical Measurement Approaches

     Abstract Practical biosolids odor prediction models were developed to be use by managers for predicting the odor emission rates of biosolids generated daily at the District of Columbia’s wastewater treatment plant. These models evaluated daily wastewater treatment process data and predicted the expected biosolids odor emissions levels prior to recycling of this material on land. ...

  • BioCycle world 2011: International Conference on Composting, Organics Recycling and Renewable Energy

  • Phosphorus partitioning in co-dewatering biosolids and water treatment residuals

    Stabilization and dewatering methods for wastewater solids determine the concentration and nature of phosphorus (P) in biosolids and in-plant sidestreams recycled to the liquid treatment facility. Because water treatment residuals (WTR) exhibit strong immobilization of soluble P, this study evaluated the impact of co-dewatering WTR and biosolids on the P partitioning during dewatering and the ...
