 Addressing the Impacts of PFAS in Biosolids

 Common sludge treatment processes, such as lime treatment, digestion, thermal drying, and composting do not reduce PFAS in sludge. Therefore, PFAS are present in both plant effluent and in biosolids at majority of WWTPs. As expected, the concentration of PFAS in biosolids is higher at WWTPs that serve industrial customers. Research has shown that plants can contain PFAS if they are grown in land applied biosolids containing PFAS. Consumption of crops containing PFAS has the potential to cause adverse health effects in people and livestock.

 To reduce or eliminate PFAS in biosolids utilities must implement an industrial pre-treatment program for PFAS source reduction. Several emerging sludge treatment technologies exist that could meet the goal of reducing biosolids disposal costs and PFAS mitigation. Emerging technologies include pyrolysis, gasification, and supercritical water oxidation and will be covered.

Dr. Viraj deSilva is a Senior Treatment Process Leader at Freese and Nichols with more than 30 years of progressive experience in water and wastewater engineering, including landfill leachate and PFAS management, from concept through construction and start-up. His national and international experience includes specific expertise in PFAS regulation and treatment. Viraj provides consultation to municipal clients on upcoming regulations, such as PFAS, and how to upgrade existing treatment processes to comply with new regulations. He is the current Chair of the WEF PFAS Task Force and an advisor to EPA, AWWA and SAME on the topic. His PFAS Sampling and Investigations, PFAS Treatment, and PFAS Waste Management experience extends to six states. He currently serves on the Technical Advisory Group at four universities conducting PFAS Research.

Viraj has been published in or presented in more than 240 industry journals and conferences out of which 76 are PFAS related. He has authored EPA, WEF, ASCE and AWWA manuals of practice. His recent PFAS work is cited in AWWA and EPA publications. His AWWA paper “Managing and Treating PFAS in Membrane Concentrates” was selected for the 2021 AWWA Membrane Treatment Best Paper Award.
