Finding Energy in Biosolids

Presentation 1:  Sustainable Biosolids Management with Thermal Drying and Co-Digestion, Sharon Foley, HRRSA and DJ Wacker, RK&K

In late 2019, the Harrisonburg-Rockingham Regional Sewer Authority (HRRSA) commissioned a new thermal dryer system to produce Class A E/Q biosolids at its 22 MGD North River WWTF. HRRSA also utilizes co-digestion of high strength waste and heat recovery to leverage its digester gas for fueling the dryer system, which requires zero supplemental propane. This presentation will discuss project goals and drivers, project planning, operations and maintenance considerations, beneficial use of the new Class A product and lessons learned from both the Owner’s and Engineer’s perspective.

Sharon Foley, PE, is the Executive Director for HRRSA which provides wholesale wastewater treatment services to 5 municipal jurisdictions in the central Shenandoah Valley of Virginia. HRRSA serves a population of approximately 80,000 residents, owns and operate the North River WWTF and discharges enhanced nutrient removal quality effluent to the Chesapeake Bay watershed.

 DJ Wacker, PE, is a Project Manager for RK&K which was the prime consultant for HRRSA’s Enhance Biosolids Reuse and Reduction project. DJ’s experience is concentrated in the planning, design and construction of wastewater treatment plants. His biosolids experience includes evaluation and design of thickening, anaerobic digestion, dewatering, drying and digester gas conditioning and utilization processes.
