About the Project

This studentship is now open to applicants from outside the UK.

This exciting opportunity is a fully funded PhD studentship, which will investigate the application of advanced oxidation processes for drinking water treatment making use of light-emitting diode (LED) technology, with an enhanced stipend of £19,000 per annum for a duration of 3 years. Part-funded by EPSRC, this project brings together a collaboration between an SME technology provider, Typhon Treatment (www.typhontreatment.com), and an end user, Anglian Water (www.anglianwater.co.uk), facilitating the route for scientific discovery to be implemented at large scale. The successful candidate will be in regular contact with Anglian’s Innovation Discovery and Typhon Treatment’s scientific teams and will be part of the Drinking Water group at Cranfield’s Water Science Institute.

Micropollutants such as pesticides, pharmaceuticals or personal care products are present in water bodies due to anthropogenic activities. In the UK, pesticides in drinking water are regulated to a limit of 0.1 µg/l for each individual pesticide or 0.5 µg/l for the sum of all pesticides. Many of these compounds are persistent to conventional treatment and new solutions that increase resilience of water supply are needed. Advanced Oxidation Processes (AOPs) are a group of chemical processes based on the in-situ generation of oxidative radicals, which can efficiently react with persistent pesticides and other compounds, removing them from water. Many AOPs require the use of UV light to produce oxidative radicals, which increase the treatment cost, but thanks to the development of light-emitting diodes (LEDs) a new door is open not only to lower costs, but to enhance operation, reactor design and sustainability.

UV/Chlorine is an emerging AOP with potential application for drinking water treatment. However, the complex chemistry behind the UV/Chlorine process, which is not yet fully understood, has resulted in conflicting reports in the literature about its efficiency to degrade micropollutants.

This project will build on previous research developed at Cranfield University in collaboration with Anglian Water and Typhon Treatment. This research aims at determining the process variables affecting pollutant degradation mechanisms; identifying the fate degradation by-products from target micropollutants during UV/Chlorine treatment; investigating the impact of other processes upstream and downstream of the UV/Chlorine process; understanding the influence of different LED operation modes on the UV/Chlorine process efficiency.

It is expected that this research will unlock the full potential of the UV-LED/Chlorine process for its application in drinking water treatment

The student will be able to attend national and international conferences and undertake targeted placements with both sponsor partners. The student will also benefit from the Cranfield Core Development Programme for doctoral researchers. This includes development in the areas of quality of information, research ethics, data analysis, writing, communication and presentation skills, leadership, employability and well-being.

In addition to the experience that the student will gain in the academic environment, this project exposes the student to gaining an insight into technology companies and a water utilities work. This opportunity provides a platform to support the development on research competency and ethics, communication skills, working across teams with different stakeholders, project management, and developing a professional network. These skills will position the student in the right place to develop a successful career in the water sector or academia.

Entry requirements

Applicants should have a first or second class UK honours degree or equivalent in a related discipline such as chemical engineering or chemistry. The ideal candidate should have some understanding of water chemistry and treatment. We are looking for an enthusiastic, engaging, self-motivated individual, curious about science and with good communication skills for regular interactions with supervisors and project stakeholders. An MSc in a related discipline or prior experience in the water industry would be advantageous, but not essential.
