Project Description
Project Overview
This exciting fully funded PhD, sponsored by Anglian Water, Thames Water, Yorkshire Water, Northumbrian Water, and EPSRC, addresses the challenge of PFAS (forever chemicals) in drinking water. The project aims to develop a predictive model using experimental data from testing to support utilities’ evidence-based decision-making to improve the resilience and cost-effectiveness of forever chemicals removal from water.
PFAS are micropollutants of growing concern globally, with new regulations requiring effective removal in drinking water. Granular Activated Carbon (GAC), a common treatment, faces cost and sustainability challenges due to shortened regeneration cycles with PFAS compared to other pollutants.
What You Will Do
- Produce experimental data characterising PFAS removal in GAC systems.
- Build a mechanistic-driven multicomponent model representing PFAS removal in GAC filters.
- Validate the model with data from live treatment plants.
Expected Outcomes
The model will enable water companies to forecast GAC bed life under varying water qualities, reduce monitoring burdens, and support proactive compliance with future PFAS standards. The project will deliver cost savings, optimized GAC operation strategies, reduced experimental testing, and minimized PFAS analysis costs.
Why It Matters
This research provides an evidence-based approach contributing to strategic planning and future-proofing water infrastructure against PFAS regulations. It promotes efficient GAC use, reduces carbon footprint and operating expenses, and supports sustainability in the water industry. Collaboration with leading water companies and EPSRC ensures access to training, experimental facilities, and international placement opportunities.
