PuriflOH (ASX: PO3) has achieved major milestone as part of the ongoing development of its proprietary PFAS destruction technology (FRG).
Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic organofluorine chemical compounds Per- and polyfluoroalkyl substances that are assessed to have the potential to cause damage to the liver and the immune system.
Independent verification and validation has been performed independently by Osmoflo at its facilities in Burton, South Australia. To ensure reliable analytical results, the PFAS content of water samples was assayed separately by two NATA-accredited laboratories: ALS and Leeder Analytical.
PFAS Remediation Testwork
PO3’s proprietary PFAS destruction technology (FRG) was challenged with contaminated water samples representing typical runoff water, with PFAS concentrations of 200 – 500 ppt, and typical highly concentrated reverse osmosis brines with PFAS concentrations of 10,000 - 500,000 ppt, usually stored onsite as hazardous waste.
Water from two key sites – a South Australian Managed Aquifer Recharge (MAR) well and an Australian Department of Defence base – was treated using PuriflOH’s PFAS destruction process.
The company’s single-step, in-situ treatment technology achieved an unprecedented result of 99.5-100% destruction of harmful PFAS compounds in all tests. Short, energy-saving cycles (7-10kWh/tonne) achieved 100% PFAS destruction in runoff samples, and greater than 99.5% PFAS destruction in concentrated brines. 20 - 25kWhr/tonne cycles achieved 100% PFAS destruction in all samples, including concentrated brines.
Further, PO3’s PFAS destruction technology fully mineralised all PFAS compounds, converting them to fluoride and carbon dioxide, thus rendering the treated water suitable for discharge into waterways (subject to presence of other contaminants).
This outcome demonstrates the robustness and effectiveness of the company’s Free Radical Generation (FRG) technology in intended use scenarios and positions PuriflOH as a unique provider of PFAS remediation solutions based on in-situ, single-step water decontamination.
The single step provides a distinct advantage over the traditional expensive and laborious two-step methodologies, in which PFAS is first concentrated on various carriers, followed by transport and incineration of the collected PFAS.
PuriflOH is focused on scaling its technology and pursuing strategic market opportunities. The Company is in discussions with several global operators with a view to identifying strategic partners to deploy its PFAS destruction technology to contaminated sites.
Additionally, PO3 is exploring further collaborations and partnerships to accelerate the commercialisation of its solutions for government agencies and environmental remediation firms seeking effective and sustainable remediation solutions for PFAS contamination.
