PFAS, also known as "forever chemicals", are substances with an extremely strong carbon-fluorine bond that are difficult to decompose. Electrons are usually paired and stable, but because radical species are unstable, they are effective in promoting the breakdown of PFAS. In high-concentration contaminated water, the concentration reduction rate of up to 99.98% was confirmed under the conditions of this demonstration. We provide solutions through a deeper understanding of the issues facing society and our customers to contribute to realizing a sustainable society. By leveraging its proprietary ultrasonic technology, the company is engaged in the development of technologies for the degradation and detoxification of per-and polyfluoroalkyl substances(PFAS).
