Prediction of Forever Chemical Concentrations in Real-World Drinking Water Treatment Systems - PhD Cranfield University in United Kingdom

This fully funded PhD position at Cranfield University addresses the urgent challenge of per- and polyfluoroalkyl substances (PFAS), also known as "forever chemicals," in drinking water treatment systems. Sponsored by Anglian Water, Thames Water, Yorkshire Water, Northumbrian Water, and EPSRC, the project aims to develop a predictive model using experimental data to support utilities in evidence-based decision-making for resilient and cost-effective PFAS removal.

PFAS are micropollutants of increasing concern in the UK and globally, with recent regulatory guidelines requiring effective removal from drinking water. Granular Activated Carbon (GAC) is a key process in PFAS strategy plans, but its regeneration frequency can be drastically reduced by PFAS guidelines, impacting cost and sustainability. Water utilities currently rely on intensive sampling and expensive analysis to characterize PFAS behavior in GAC beds.

The research will deliver a model integrating water quality to predict PFAS behavior in GAC filters, providing water companies with a practical tool to forecast GAC bed life under varying water qualities, reduce monitoring burden, and enable proactive compliance with future PFAS standards. The mechanistic-driven multicomponent model will be built and validated using experimental data from live treatment plants.

Key impacts include cost savings from optimal GAC operation, accurate regeneration strategies, reduced need for experimental testing, and minimized PFAS analysis costs. The project will contribute to strategic planning for forever chemicals, future-proofing assets for current and future regulations, and promoting sustainability by reducing carbon footprint and OPEX.

This collaboration involves the Cranfield Water Science Institute and several major water utilities, as part of the EPSRC Centre for Doctoral Training in Water Infrastructure and Resilience (WIRe). The WIRe programme offers bespoke training in technical and personal skills, opportunities for overseas travel, and access to world-leading experimental facilities. An international placement is also available.

The doctoral centre is inclusive and welcomes applications from all highly motivated individuals, regardless of background, identity, or disability. Graduates will be well positioned for successful careers in the water sector or academia, supported by development in communication, project management, leadership, and an international network.

Entry requirements include a first- or second-class UK honours degree or international equivalent in chemical engineering, chemistry, environmental engineering, environmental science, or related fields. Understanding of water science and modelling skills are desirable. The position is open to both Home and Overseas fee status students, with limited studentships for Overseas status. The funding package includes a tax-free bursary of £25,726 per annum and registration fees for four years.
