This PhD position offers an exciting opportunity to do pioneering research on the recovery of nutrients and metals from water treatment sludge to embrace the circular economy and protect our environment. Worldwide, the demand for iron salts for treatment is rapidly increasing as improved water quality targets are required, thus generating both a risk to supply and excess waste that needs disposal. The ambition of this project is to establish the basis to harness natural biological processes for resource recovery, enabling resilient and sustainable water treatment within planetary boundaries. Ultimately this will change the way we think about coagulant use and help us transform towards a circular economy.
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. 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). More details of the CDT WIRe at www.cdtwire.com
We are an inclusive and diverse doctoral centre and welcome applications from all highly motivated individuals, regardless of background, identity or disability.The production of potable water and enhanced treatment of wastewater are heavily dependent on chemical use. Currently both use fresh coagulant once before disposal, which generates waste and requires further mining of minerals to generate fresh coagulants. There is an urgent need to re-think how resources are used respecting planetary boundaries. Work to date has been based on chemical recovery processes, which can have prohibitive financial and environmental costs. This PhD opportunity postulates that recovery can be made sustainable using innovative biological processes.
The project aims to understand, improve and accelerate the use of microorganisms for iron-based coagulant recovery. The work will explore the conditions under which specific organisms can naturally cycle iron from waste into a recoverable product for local reuse, and propose ways to optimise this. As such, the ideal candidate will have a strong background in either microbiology or an engineering discipline, and a desire to apply it to drive towards a sustaining circular use of coagulants for improved environmental impacts. The work will be primarily in the laboratory, with frequent contact and opportunities for intellectual discussions with the expert team within Cranfield Water.
The project is part of the CDT WIRe and is co-sponsored by four water utilities, illustrating the applied science components as well as the real-world impact of the expected results. There will be opportunities to disseminate the research findings at both academic conferences and industrial networking events, as well undertaking an international placement. The multiple skills needed to deliver this work will be developed through hands-on training and a bespoke training programme depending on the candidate’s first degree and post-graduation ambitions. As part of WIRe, the student will participate in inspiring group activities as well as complete technical and transferable skills modules within a cohort of up to 15 students. Upon graduation, the student will be well placed to pursue a successful career that has a positive impact in the world.
