With growing challenges in biosolids disposal and rising concerns around emerging contaminants like PFAS, biosolids management strategies are evolving. This webinar outlines a biosolids road map and risk triggers analysis for utilities to plan effective management and PFAS reduction strategies. While the US EPA continues its risk assessment of PFAS, we’ll discuss current trends, barriers, and the future regulatory landscape impacting technology and resource recovery.
Our presenters share cutting-edge innovations that transformed biosolids management by reducing mass and volume, while potentially avoiding landfill or land application. They explore technologies like electro-dewatering and thermal options — such as gasification, pyrolysis, and hydrothermal processing — alongside updates on current research and real-world implementations addressing PFAS and other emerging contaminants.
Meet the speakers:
- Terry Goss, VP, Eng. Terry leads our biosolids practice leader in North America. He has two decades’ hands-on experience with biosolids process design, equipment integration, project delivery and plant commissioning. He has a strong background with anaerobic digestion, drying and energy recovery systems and has been at the forefront of tracking the impacts of PFAS in biosolids.
- Ganesh Rajagopalan, Ph.D., P.E., BCEE. Ganesh is our resource recovery practice leader in North America. He has 25 years’ experience with wastewater, sludge and biogas treatment research, pilot testing, planning, and process design. He has performed several research studies, pilot and full-scale demonstrations of co-digestion projects to enhance biogas recovery for various beneficial uses. Ganesh was the principal investigator for a recently completed three-year, $1.5 million full-scale demonstration of the food waste pre-processing and co-digestion at Silicon Valley Clean Water facility at Redwood City, California. He holds a patent for enhancing sludge dewatering using nanoscale polymer additives.
- Tim Abbott, Ph.D., M.A.Sc., E.I.T. Tim has 12 years’ experience exploring and optimizing anaerobic and aerobic digestion, hydrothermal liquefaction, and other biosolids treatment processes to better treat trace contaminants, odors, and nutrients. He provides municipalities advice and system design on process changes, facility plans and upgrades, and research projects.
