US agency Claros Applied sciences has accomplished a commercial-scale run of its proprietary UV-photochemical PFAS destruction methodology, reportedly reaching over 99.99% destruction throughout lengthy, quick, and ultra-short chain PFAS whereas treating greater than 170,000 gallons of business wastewater at excessive stream.
Introduced on 15 December, the work was carried out with Daikin America – the US manufacturing arm of Japan-based Daikin Industries and one of many world’s largest PFAS producers. It seems to have been one of many largest-scale – if not the biggest – trials of in-field PFAS destruction ever carried out.
In contrast to high-temperature incineration – to this point the one definitive PFAS destruction resolution, in some value determinations – the UV-based destruction methodology is relevant to high-flow industrial wastewater, doubtlessly permitting PFAS destruction with out intermediate seize and off-site transport. If the method is validated at full scale, it may subsequently scale back reliance on downstream disposal pathways.
“Over the previous yr, we’ve confirmed that full PFAS destruction at industrial scale isn’t theoretical—it’s taking place now,” mentioned David Hendrixson, Government Vice President of Daikin America.
On this newest section, the ClarosTechUV™ system handled greater than 170,000 gallons (roughly 640,000 liters) of business course of water containing a spread of PFAS compounds. The system achieved larger than 99.99% destruction of all focused PFAS species—lengthy, quick, and ultra-short chain—at excessive stream charges able to lots of of gallons per minute whereas demonstrating secure efficiency and distinctive power effectivity as properly.
By means of its collaboration with DAI and different industrial companions, Claros mentioned it has now processed greater than half one million gallons of PFAS-containing industrial course of water at industrial services, demonstrating constant, verified destruction efficiency throughout various concentrations and water chemistries.
The 2 corporations are actually mentioned to be working in direction of engineering and system specs for the primary full-scale PFAS destruction business set up.
The ClarosTechUV™ next-generation PFAS destruction system seemingly demonstrated: effectiveness throughout lengthy, quick, and ultra-short chain PFAS (together with TFA); 99.99% destruction of PFAS throughout all focused species; a high-flow functionality of lots of of gallons per minute (1000’s of litres per minute); a compact footprint for seamless integration; a secure, dependable UV-based expertise; and low-cost efficiency suited to industrial remediation functions.
