Claros Technologies has validated its ClarosTechUV system at commercial scale, destroying at least 99.99% of PFOS and PFOA in highly contaminated groundwater concentrate sourced from the Minnesota Pollution Control Agency’s Lake Elmo remediation site. Using foam-fractionation concentrate derived from roughly one million gallons of contaminated groundwater and surface water, the pilot showed the system can operate effectively in low-transparency, high-turbidity conditions that mirror real-world remediation challenges.
In the large-scale run, ClarosTechUV treated concentrate representing about 600,000 gallons of groundwater in four hours, with energy use below 200 Wh per liter and an operating cost of about $0.015 per 1,000 gallons of untreated groundwater, positioning the technology as a potentially cost-competitive alternative to PFAS management and disposal. Analytical work by ClarosLabs, using a modified EPA 1633 method and combustion ion chromatography, confirmed about 88% reduction in total organic fluorine and a corresponding increase in inorganic fluoride, indicating mineralization rather than transfer of PFAS to another waste stream; executives said the results expand Claros’s addressable market in large-scale groundwater and remediation projects and demonstrate that the platform scales reliably from lab to full-field deployment.
