PURIFLOH LIMITED (PO3)

The company lodges its Quarterly Activities/Appendix 4C Cash Flow Report.

PuriflOH Limited continues to advance its proprietary PFAS removal technology with ongoing testing providing further validation and encouraging results. The latest series of experiments focused on validating an even more energy efficient methodology, whilst being safer to humans and to the environment. The results have provided confirmation of both previously successful PFAS destruction methodologies being suitable for larger scale operations and of the improved ones being suitable for smaller scale local operators, of which there are many. The economic feasibility of these solutions for both smaller and larger scale water purification operations will likely be compelling. The most recent results and the protocols of the tests will now be used in preparation for upcoming field trials in conjunction with Osmoflo. The IP for PFAS destruction using the new PuriflOH proprietary technology is being finalized in preparation for the field trials. Market awareness of the issue of PFAS is growing. The Company is keeping track of media attention on the issue and the scope of the problem in relation to where PO3's unique solution will apply.

PuriflOH Limited has progressed the applicability of its new PFAS removal technology, substantially decreasing the energy consumption and contact time requirements. When challenged with levels of PFAS typically found in contaminated water, an improved FRG-based system also demonstrated capability to destroy PFAS within minutes and at a power consumption of approximately 0.0001 KWhr/litre. This is 10-15 times faster and with 20-30 times less power consumed than previously reported. The achieved process parameters indicate a potential breakthrough in PFAS removal industrial solutions, where PFAS could be substantially removed in a simple in-line flowthrough process as opposed to current state of the art batch processes that require storage of large volumes of contaminated water. Since PFAS represent the worst-case scenario of industrial water contamination with stable organic compounds, PuriflOH's proprietary solution could be applicable to any land remediation or decontamination processes required for reclaiming industrial sites and mining waste. PuriflOH's PFAS removal process has a carbon footprint that is a fraction of that of activated carbon. Activated carbon provides similar removal efficiency of PFAS but requires incineration of filtration material, incurring high costs and energy consumption. On the other hand, PuriflOH's process is designed to destroy PFAS compounds via complete oxidation without any by-products. Results are likely to be enhanced further with more optimization testing, which is now underway.

The company releases a notice of application for quotation of securities.

The company has executed a Memorandum of Understanding with Osmoflo Water Management Pty Ltd, dated 15 August, 2023, to jointly explore the potential for the use of the PuriflOH Free Radical Generator in water treatment systems. The duration of the MoU spans two years initially, with the possibility of extension through mutual accord. The essence of this partnership involves a joint-funded effort to assess the technical and financial viability of the FRG water treatment system. Furthermore, the parties intend to pursue the commercialization of any resulting products or systems stemming from this collaboration. The key area of exploration with Osmoflo is to investigate and verify the potential for the FRG to destroy Perfluoroalkyl and Polyfluoroalkyl substances on a commercial scale.

company and a fully owned subsidiary of Hitachi Zosen Corporation, of Japan, has provided an evaluation of the PuriflOH water treatment system based on extensive validation testing conducted over 11 months. Preliminary results are successful as measured by Osmoflo wishing to enter into a formal engagement for future development and commercial exploitation. Following the success in the validation testing, pilot testing and co-development of products and technologies in key water treatment sectors are being planned. The combination of radicals produced by PuriflOH's Free Radical Generator creates an Advanced Oxidation Process environment in water and acts as a powerful water treatment method to destroy all microbial and chemical contaminants in the water. FRG shows capability of PFAS removal.
