[School of Natural Sciences PhD Scholarships] Destruction of organic pollutants using novel electrochemical oxidation technology; Evaluating impact of metals on the removal efficiency.

About the project

About the Project Increased discharge of potentially toxic, hard-to-remove organic pollutants (pesticides, antibiotics etc) is causing major environmental/economic damage worldwide. Since these pollutants cannot easily be removed using conventional techniques it represents a real challenge for the (waste)water industry. There is therefore an urgent need to develop treatment technologies that could efficiency/sustainably destroy these pollutants, without the generation of toxic breakdown products. The Nyex Rosolox (NR) is such a novel water treatment technology, which makes use of an adsorption and electrochemical regeneration process, to remove and completely oxidize organic contaminants from aqueous solutions. The process uses a low capacity, proprietary graphitic adsorbent material (Nyex) that can be electrochemically regenerated. Although, this technology might provide a simple, flexible and reliable solution to removing a wide range of pesticides, dyes and organometallic pollutants [1-4], with significantly lower operating costs than traditional alternatives it remains unclear whether this is possible under realistic effluent conditions. This since the effectiveness of removing target organic contaminants in complex effluents, such as (natural) peat waters, containing high amounts of iron-bound organics or other metals are still poorly understood. It remains unclear what happens to these metals after the treatment, if it ‘poisons’ the Nyex media, which can have a negative impact on the treatment process. This project therefore seeks to evaluate the impact that the presence of iron or other metals has on the NR process removal efficiency of a wide range of organic pollutants in complex synthetic and natural water matrices. Using small scale setups, you will assess the efficiency of the process in destroying iron- (and other metal) bound organics, present in organic rich waters, including demonstrating that no toxic breakdown products are generated by the electrochemical oxidation. You will explore what happens to the metals after the treatment and what the long-term impacts of the presence of these metals are on the efficiency of the NR process for a range of organic pollutants (dyes, pesticides and antibiotics) in a variety of effluent conditions. Combined this will lead to a step-change in our fundamental understanding of the NR process efficiency, further positioning this technology as a promising solution for sustainable water treatment. This project is open to candidates with backgrounds relevant to environmental science/engineering or chemistry and some experience of one the following would be advantageous: UV spectroscopy, gas or liquid chromatography mass spectrometry, and scanning electron microscopy, however full training will be provided. The successful applicant will join a vibrant group of researchers working across themes in environmental chemistry/water pollution. We will deliver extensive training in all analytical aspects, and the applicant will have access to the state-of-the-art Williamson Research Laboratories. More widely, the applicant will gain extensive training in project planning, communication, networking and outreach which will be augmented by their interaction with the Manchester Doctoral College. This project is expected to start in September 2027. Before you apply: We strongly recommend that you contact the supervisors for this project before you apply.
