 Microwave reactivation of Granular Activated Carbon – Building capacity to manage PFAS

Amount awarded: £1,910,585 

Led by: Severn Trent 

Partners: CPL – Puragen, University of Nottingham, Cranfield University, Yorkshire Water, Anglian Water, South West Water, Dŵr Cymru Welsh Water 

Removing PFAS “forever chemicals” from drinking water will significantly increase the use of Granular Activated Carbon (GAC) and exceed the reactivation capacity available in the UK. We will develop an industrial-scale microwave solution to increase capacity, providing a faster, cheaper and sustainable low carbon alternative to traditional gas-powered reactivation furnaces. 

“Ofwat’s Innovation funding will enable us to prove and accelerate the use of clean, energy efficient microwave technology for reactivating GAC. This will help the water industry provide a safe and sustainable supply of water and make the UK a world leader in GAC reactivation technology.”
