Providing clean water for all remains one of the main challenges for humanity and thus is one of the UN’s Sustainable Development Goals (SDG6). In this project, we will address this challenge by investigating the potential of a recently discovered process involving natural sedimentary minerals to sustainably treat water. The process relies on the production of hydroxyl radicals to degrade organic pollutants during the reaction of reduced iron in clay minerals with oxygen and the sustainable regeneration of clay mineral reduced iron by microbes under anoxic conditions. However, it is currently unknown whether treatment efficiency can be maintained over several cycles of use and re-generation under realistic environmental conditions.
Using mesocosm experiments, we will evaluate the sustainability of the treatment and regeneration processes; monitor the evolution and efficiency of the microbial communities driving clay mineral reactivity regeneration (via DNA/RNA metabarcoding); and examine the suitability of ecological indicators and analytical techniques as novel, low-cost tools for performance monitoring. This interdisciplinary project will provide the proof of concept that a low energy, low input (waste) water treatment system harnessing microbially mediated redox processes of iron-bearing clay minerals can be operated sustainably and at scale. The overall aim is to demonstrate a feasible water treatment approach for high, middle, and low-income countries alike.

Your background should be in environmental chemistry, geochemistry, microbiology or a related discipline (minimum 2:1 honours degree or international equivalent), with experience in the laboratory. You should be motivated to engage in interdisciplinary work and to conduct extensive laboratory work, including aqueous and solid phase analyses (HPLC, ICP-MS, XRD, Mössbauer spectroscopy) and molecular biology techniques (DNA/RNA sequencing, metabarcoding). Experience in any of these techniques would be advantageous.
The award is available to UK/EU applicants only. Depending on how you meet the EPSRC’s eligibility criteria, you may be entitled to a full or a partial award.
