In a recent edition of Australian Water Association’s e-journal, ECT2’s team of experts published an article about a five-year case study of the treatment of PFAS-impacted groundwater at a project site in Australia. Regenerable ion exchange resin for PFAS remediation has been in service in Australia since September 2017. Currently, five regenerable systems are continuously operated for remediation purposes, and another regenerable system is providing municipal drinking water treatment. This article provides an update on PFAS treatment using regenerable resin data from bench, pilot, and full-scale systems. A comprehensive breakdown of total water treated and mass of PFAS removed to date is provided, as well as details on resin optimization work and data on regeneration efficiency. Since 2019, 26 regeneration cycles have been performed at these sites, without build-up of residual PFAS on the resin.
