en.Wedoany.com Reported - Swiss cleantech company Oxyle has validated the effectiveness of its proprietary photochemical reduction technology, OxLight, under real industrial conditions during an on-site pilot at an industrial facility. The technology was used to degrade and defluorinate two process wastewater streams containing high concentrations of ultra-short-chain C3 PFAS compounds. This trial further expands the company's portfolio of customer validations and advances the commercialization of permanent PFAS destruction technology.
The pilot evaluated two wastewater streams containing the same ultra-short-chain C3 PFAS compounds but with significantly different matrix characteristics and contaminant concentrations. Oxyle tailored the OxLight process design for each matrix. In the inorganic-rich wastewater (PFAS concentration approximately 20-25 ppm), the system achieved over 99% degradation; in the high-organic wastewater (PFAS concentration approximately 70 ppm), the degradation rate exceeded 97%. Fluoride release measurements confirmed the cleavage of carbon-fluorine bonds, demonstrating that the PFAS had been permanently destroyed.
OxLight is Oxyle's proprietary destruction technology, which decomposes PFAS compounds on-site by combining ultraviolet light with mediator chemicals. Unlike adsorption and filtration methods that only concentrate PFAS onto used media or secondary waste streams, OxLight offers a destruction solution. This technology forms the core destruction stage of Oxyle's modular destruction system, with additional optimization stages that can be added as needed based on each site's water chemistry, PFAS profile, discharge requirements, and treatment objectives.
In addition to demonstrating treatment performance, the pilot generated critical engineering and operational data required for a full-scale process designed to achieve a 99.9% degradation rate. This includes insights into process operability, design parameters, process conditions, and economic performance under real industrial conditions. These results further solidify the foundation for commercial-scale deployment of Oxyle's PFAS destruction solution across a wide range of industrial wastewater applications.
Dr. Fajer Mushtaq, co-founder and CEO of Oxyle, stated: "Ultra-short-chain PFAS are among the most persistent and difficult-to-treat contaminants in water treatment. These pilot results demonstrate the successful destruction of these compounds and the adaptability of our solution to the complex wastewater conditions faced at customer sites. The resulting dataset provides an empirical basis for engineering a full-scale solution targeting a treatment rate greater than 99.9%."
