Abstract
There is growing awareness of, and concern about, the fate and human and environmental impacts of per- and polyfluoroalkyl substances (PFAS) that are introduced to wastewater treatment plants (WWTPs). In this report, a simple model was developed using the BioWin 6.0 (EnviroSim Accociated Ltd. 2019) WWTP simulation and design software and used to assess the fate of two key PFAS, perfluorooctanesulfonic acid (PFOS) and 2-(N-ethylperfluorooctanesulfonamido)ethyl alcohol (EtFOSE). Sensitivity analysis was performed, and the impact of process changes on the production of wastewater treatment solids and the concentrations of these PFAS in the biosolids were analyzed and are summarized in this report. Modeling results concluded that the concentration PFOS in sludge is dependent on the operational decisions, such as solids production, solids retention time (SRT), sludge thickening, and changes to aeration. The parameters that are sensitive in the model are influent chemical oxygen demand (COD) and the liquid phase mass transfer coefficient, KL.
