Granular Activated Carbon (GAC) is used to remove organics, such as pesticides and taste and odour compounds. GAC needs to be regenerated thermally, typically every 3 years, which is both costly and carbon intensive. This project will investigate different ways to regenerate GAC locally reducing both financial and carbon costs. 

“This funding will enable Welsh Water to lead this innovative project, exploring transformative ways of regenerating granular activated carbon locally rather than the traditional thermal regeneration route, which is both costly and carbon intensive.” – Paul Gaskin, Innovation, Optimisation and Compliance Manager, Dŵr Cymru Welsh Water
