Installation, Operation and Startup of Australia's First Regenerable Resin System for PFAS Removal
A 200-gpm regenerable ion exchange (IX) resin system was selected by the Australian Department of Defence to remove PFAS from groundwater at the Royal Australian Air Force Base Williamtown. The system treats groundwater from the former fire training area and was installed during spring/summer 2018. It includes pretreatment filtration to remove suspended solids, IX resin to remove fouling agents including iron and natural organic matter (NOM), specialized ion exchange resins for PFAS removal, and an in-vessel regeneration process used to strip PFAS from the IX resin.
Influent concentrations to the full-scale system range from 18 to 410 ug/l. In addition to describing system installation and startup, this paper will present the system’s PFAS removal results for the first several months of operation. The efficacy of the in-vessel resin regeneration system will also be described, along with the effectiveness of waste minimization efforts, including distillation and super-loading.
