A PhD position is available in the frame of the joint alliance research project “Development of digital twins to improve control and operation of (urban/industrial) water treatment systems” funded by the Technical University of Denmark. The project is in close collaboration with the Advanced Water Management Centre (AWMC) at the University of Queensland (Australia) and will deliver a set of virtual replicas of the different technologies comprising the flow diagram of the water treatment systems under study (Denmark, Australia).

The digital twin will enable process engineers to make more informed decisions about how to optimize: 1) energy recovery, 2) chemical use, 3) operational procedures, 4) sludge handling and 5) retrofitting equipment (=capacity liberation in the plant). The topic covered in this proposal is aligned with multiple UN Sustainability Development Goals : 6 (clean water and sanitation) 7 (affordable clean energy), 11 (sustainable cities and communities) and 14 (life below water). In general, the project aims towards a more circular economy where the waste generated from one industry becomes a secondary raw material for another and there is a lower dependency on raw material imports. 

Responsibilities and tasks
The PhD student will develop different types of mathematical models describing industrial / urban water treatment systems, and will furthermore focus on how to improve treatment system performance. The tasks will include, but not be limited to  

  • Design and participate in different types of measuring campaigns (full-scale)
  • Data collection and reconciliation
  • Model construction, mass balance verification and model coding
  • Calibration and validation exercises
  • Scenario analysis
  • Economic and sustainability analysis
  • Communication of results with industrial partners
In accordance with the above-mentioned tasks, the applicant should preferably have qualifications within several of the following areas: 
  • Experience in use of different types of statistical software packages
  • Experience in modelling of biological and physico-chemical processes
  • Experience in use of different types of simulation tools such as Matlab / Simulink or similar
  • Experience with the use of life cycle assessment methodologies
Expertise with biochemical/environmental engineering should be documented with the Master/Bachelor thesis and/or relevant publications in international journals. 

The project and co-supervision of the PhD student will be in close collaboration with personnel enrolled in the Advanced Water Management Centre at the University of Queensland (Australia) and long external stays at the University of Queensland will take place throughout the duration of the PhD project. Availability for a longer stay abroad, openness and willingness for establishing a fruitful collaboration across borders is therefore a prerequisite. 

Qualifications
Candidates should have a two-year master's degree (120 ECTS points), preferably in chemical or biochemical engineering, or a similar degree with an academic level equivalent to a two-year master's degree.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the
DTU PhD Guide


Assessment
The assessment of the applicants will be made by an evaluation committee headed by Professor Krist V. Gernaey & Senior Researcher Xavier Flores-Alsina (DTU) and Prof. Damien Batstone (UQ).
