Florence Wastewater Treatment Facility Optimizes Biosolids Composting<\/h2>\n

In 2009, the City of Florence, under the direction of City Public Works Director Mike Miller, commissioned a study to explore treatment methods that could provide value-added processing for the town\u2019s biosolids.<\/p>\n

SG SOLUTION: Pilot-Scale Composting Proves Cost-Effective for Class A Biosolids<\/strong><\/p>\n

To evaluate cost-effective composting technologies for biosolids management, the City of Florence launched a pilot demonstration project in 2010 using the SG MOBILE\u00ae System. After comparing various composting methods, the City selected this system due to its modular design, no permanent construction requirements, or hard-wired infrastructure.<\/p>\n

The pilot successfully demonstrated the system\u2019s ability to:<\/p>\n

    \n
  • \n

    Produce Class A biosolids compost<\/p>\n<\/li>\n

  • \n

    Meet the EPA Rule 503 pathogen reduction and Vector Attraction Reduction (VAR) standards<\/p>\n<\/li>\n

  • \n

    Deliver high performance at a lower capital investment<\/p>\n<\/li>\n<\/ul>\n

    Following the successful pilot, the City was awarded a $100,000 Waste Diversion Opportunity Grant<\/strong> from Lane County in 2012 to develop a small-scale biosolids composting facility. Sustainable Generation, LLC was selected to supply a permanent SG MOBILE\u00ae System with above-ground aeration.<\/p>\n

    Installed in winter 2012, the system now enables the Florence Wastewater Treatment Facility to process up to 600 tons of biosolids annually into high-quality, Class A EQ compost, meeting both regulatory and community sustainability goals.<\/p>\n
