  • Startup of Anaerobic Mesophilic Digesters

    Many operators have started up mesophilic digesters, but everyone has differing stories and experiences. This paper is a combination of the startup of several mesophilic anaerobic digesters, with very low seeding to fully seeded conditions. Upper Occoquan Sewage Authority (UOSA) operates the Millard H. Robbins Water Reclamation Plant. UOSA started three anaerobic digesters between August 2000 and ...

  • Anaerobic Digestion at Dairy Farms

    The need to upgrade dairy waste management practices to overcome pollution problems is leading more farmers to seek solutions with anaerobic digestion technology. Two recent examples of this trend are underway at California sites. The Cal Poly Dairy is located adjacent to the California Polytechnic State University campus in San Luis Obispo. The dairy milks 180 cows with a total population of ...

  • Effect of Secondary Aerobic Digestion on Properties of Anaerobic Digested Biosolids

    ABSTRACTIn this study, the performance of sequential anaerobic-aerobic digestion was compared to conventional anaerobic digestion for sludge from the Blue Plains Advanced Wastewater Treatment Plant. Volatile solids removal, polymer conditioning demand for dewatering, and biosolids odor characteristics following anaerobic digestion and sequential anaerobic-aerobic digestion were monitored. Aerobic ...

  • Advanced anaerobic processes to enhance waste activated sludge stabilization

    The requirement for enhanced stabilization processes to obtain a more stable, pathogen-free sludge for agricultural use is an increasing challenge to comply with in the waste hierarchy. With this in mind, the Routes European project (‘Novel processing routes for effective sewage sludge management’) is addressed to assess innovative solutions with the aim of maximizing sludge ...

  • Toronto moves forward with anaerobic digestion of residential SSO

    In June 2007, Toronto's City Council approved the “Target 70” plan to achieve 70 percent diversion by 2010. Target 70 includes construction of two, 55,000 metric tons/year anaerobic digestion plants to process residential source separated organics (SSO). City Council says that the digester facilities, along with adoption of single stream recycling and a pay-as-you-throw funding system, will ...

  • Advanced Digestion Plant at Bran Sands design and construct experiences

    Abstract In June 2007 Northumbrian Water awarded a design and construct contract to Aker Solutions for a new advanced digestion (AD) plant at their Bran Sands site on Teesside. Following laboratory trials, advanced digestion via thermal hydrolysis was identified as the preferred treatment process for the upgrade of Bran Sands Regional Sludge Treatment Centre (RSTC). The plant will treat ...
