This will allow operational mitigations and investment decisions to be made by water companies to enable future reductions in risk when producing drinking water. Students will benefit from being part of the EPSRC Centre for Doctoral Training in Water Infrastructure and Resilience (WIRe), a world leading collaboration between three UK universities (Cranfield, Sheffield & Newcastle). The WIRe programme includes a bespoke training programme in technical and personal skills development, and provides opportunities for overseas travel and access to world leading experimental facilities (PhDs under this scheme are for a duration of four years full time).
Water resources are coming under increasing pressure. The greatest pressure on water supply is from population growth and development. Climate change is making these pressures even more challenging. This puts water companies in a position where the water they abstract for the production of drinking water is more likely to be impacted by sewage treatment works effluent, and climate change impacts such as algal growth and agricultural run-off will increase.
All these factors mean that the organic nitrogen levels are at significant and increasing concentrations in water being used as a drinking water source. These compounds are recalcitrant to removal by conventional treatment technologies resulting in elevated organic nitrogen levels in treated waters. This in turn impacts on the formation of nitrogenous disinfection by products (NDBPs). Disinfection by products are formed when organic matter present in treated drinking water sources reacts with the disinfectant (often sodium hypochlorite or chlorine gas). In addition to organic matter, the reactants include bromide, iodide and organic nitrogen. Although NDBPs are not regulated in the UK, legislation requires that DBP concentrations must be kept as low as possible without compromising the effectiveness of the disinfection process. In addition, a prescribed concentration of 100 µg L-1 has been set for the sum of the concentrations of the four trihalomethanes measured at the consumers tap with regulation for haloacetic acids included in the revised EC Drinking Water Directive with a likely UK standard of 60µg L-1 for HAA-5.
The aims of this project are to:
- Develop analytical methods for organic nitrogen, haloacetonitriles, halonitromethanes, haloacetamides and nitrosamines.
- Determine the impact of source waters containing different types of organic nitrogen on NDBP formation.
- Investigate the impact of treatment processes on removal of organic nitrogen compounds and subsequent formation of NDBPs at bench, pilot and full scale.
The project is an exciting collaboration between Cranfield University and UK Water Industry Research Ltd (UKWIR). UKWIR is a collaborative research platform for the UK and Ireland water sector, funded by the water utility companies operating in these countries. The project will enable water companies to develop strategies for control of NDBPs in order for them to meet the requirement for minimisation. By looking at the sources of organic nitrogen in water, its role in NDBP formation and potential routes to removal through treatment, this project will build an understanding of the fundamental science to be able to develop strategies for future investment to increase the resilience of our water supplies.
The successful applicant will make use of the Drinking Water Pilot Plant facility at Cranfield University to translate the lab results to full-scale. Additionally, as part of the WIRe doctoral centre, students will benefit from an enhanced stipend of £19,000 per annum, undertake an international placement, and complete a bespoke training programme within a cohort of up to 15 students across the three universities.
At the end of the project the successful applicant will be very well positioned to have a highly successful career in the water sector or in an academic role. We will help you develop into a dynamic, confident and highly competent researcher with wider transferable skills (communication, project management and leadership) with an international network of colleagues.

Applicants should have a first or upper second class UK honours degree, or equivalent, in a related discipline, such as chemistry or chemical engineering. The ideal candidate should have some understanding of watershed chemistry and water treatment. The candidate should be self-motivated, have good communication skills for regular interaction with other stakeholders, with an interest in applied scientific research. Prior experience in the water sector would be advantageous but is not essential.
Sponsored by EPSRC and industrial partners (Severn Trent, Thames Water, Scottish Water), this studentship will provide a bursary of £19,000 per year with fees paid. All training and placement (overseas/industry) costs will also be covered, subject to supervisor approval.
The studentship is open to UK and international students (including EU countries) however due to funding rules, no more than 30% of the projects in this cohort can be allocated to international students.
Cranfield Doctoral Network
Research students at Cranfield benefit from being part of a dynamic, focused and professional study environment and all become valued members of the Cranfield Doctoral Network. This network brings together both research students and staff, providing a platform for our researchers to share ideas and collaborate in a multi-disciplinary environment. It aims to encourage an effective and vibrant research culture, founded upon the diversity of activities and knowledge. A tailored programme of seminars and events, alongside our Doctoral Researchers Core Development programme (transferable skills training), provide those studying a research degree with a wealth of social and networking opportunities.
