Trials have been undertaken by two independent institutions, using a next generation PFAS adsorbent media developed by Puraffinity, the London based science materials company.
These show that Puraffinity’s new material performs better by lasting longer and treating three times the amount of GenX contaminants compared with current ion exchange and activated carbon technologies.
“Our adsorbent material binds the GenX contaminants like lego blocks as the water flows past,” explained Puraffinity CEO Henrik Hagemann. “And, once all the Puraffinity material is filled up with GenX, the material is engineered to unclick the bound GenX using a safe regeneration step. The Puraffinity material can then be re-used for industrial or environmental remediation, enabling a circular economy for the future of water filtration materials.”
GenX chemicals are found in products such as food packaging, clothes and firefighting foam (pictured) and a recent study identified them across 200 different use categories.
“We are excited by third party results demonstrating that our next generation adsorbent performs strongly and can deal with these pollutants to avoid serious negative situations,” said Mr Hagemann. “The adsorbent material can operate in both Brita type cartridge applications, where GenX chemicals can be removed at the smallest pitcher type scale as well as in large steel tanks or vessels for industrial applications.”
