Hydrothermal oxidation (HTO) is an advanced thermal conversion approach which offers a unique route to address landbank challenges whilst unlocking valuable resources and preventing process emissions. Anglian Water are exploring the deployment of HTO with Cetogenix, Cranfield University and AtkinsRéalis within ambitious Ofwat Innovation projects (Catalyst and Transform). The team are investigating the potential application of HTO system to process biosolids at up to 3 tDS/d at a UK bioresources centre and the viability for a range of technologies to recover resources from its effluent. As a key enabler for the UK demonstration in the Ofwat Transform project, Cetogenix have developed and operated a continuous HTO pilot plant which yields a suite of energy and nutrient products. Over the past 12-months, they have focused on process performance using real sludges and the fate of carbon, nitrogen and phosphorus which will be critical aspects for scaling the technology. Lessons learnt from Cetogenix’s pilot scale system to date will be coupled with a strategic assessment for its full-scale deployment at UK bioresources centres. This provides crucial insight into the emerging technology landscape for advanced thermal conversion approaches, and their potential to transform biosolids treatment, process emissions and resource recovery across the sector.
