PhD stipend in biopolymer flocculation and dewatering of lake sediment (18-21105)

At the Faculty of Engineering and Science, Department of Chemistry and Bioscience, a PhD Stipend is available within the study programme of Biotechnology, Chemistry and Environmental Engineering. The stipend is open for appointment from 1 April 2022. The position is for 3 years. The Department consists of two sections with research and teaching in Biotechnology, Chemistry, Chemical Engineering, Environmental Technology and Biology. Place of employment of the position is Section of Chemical Science and Engineering in Aalborg. In the workplace, we work for diversity in nationality, culture, and gender, growth as a team effort, maintaining an inspiring physical work environment, and ensuring a good work-life balance.

Job description

The PhD stipend is announced as part of the Circular Lake Restoration - rePair project funded by the Poul Due Jensen Foundation and the research of this PhD project will primarily focus on flocculation and dewatering of lake sediment for phosphorus extraction and recovery. The rePair project is managed by a consortium of multiple partners and close collaboration with other partners will be an integrated part of the project as well as participating in project status meetings and outreach activities. The overall aim of the RePair project is to promote a paradigm shift in lake management by restoring freshwater bodies by transforming lake sediment and phosphorus polluted lake water into valuable resources without any harmful effect on the environment.

Flocculation and dewatering are a key method for handling lake sediment and ensure that the water can be returned to the lake. Synthetic polymers are often use but may be toxic for the environment. Part of the PhD is to test and develop biopolymer as an environmental friendly alternative to synthetic polymers. Atomistic simulation and analyses of floc strength may be used as a method to design better biopolymers. Filter aids have to be tested experimentally to ensure high quality of filtrate and low water content in dewatered sediment and compared with chemical equilibrium simulation and theoretical calculation of interaction energy between biopolymers and particles. Thermogravimetric and hydro-textural method will be developed and used to predict final dry matter content and rheological properties of the dewatered sediment

Applicants must have Master of Science (MSc.) degree in Chemical Engineering, Chemistry, or similar from an internationally recognized University with a master thesis in one of the following areas: chemical engineering, process chemistry and rheology. 

We are looking for the ideal candidates and expect the candidate to have the following qualifications:

  • Practical experience with experimental research within chemistry and chemical engineering
  • Practical experience with flocculating and separation (preferred)
  • Knowledge on computational modelling (preferred)
  • Good collaboration skills, team spirit and the ability to work independently
  • High level of both spoken and written English to accommodate scientific communication and dissemination

We offer the possibility to be part of a motivated, progressive and internationally recognized multi-disciplinary research environment under the headline of chemistry and chemical engineering. This includes access to state-of-the-art laboratory facilities, a chance to see your research be brought into practice and freedom to develop your research project within the stated framework. The candidate will be provided a team of supervisors from AAU from campus Aalborg and co-supervision from partners at Aarhus University and DIS/CREADIS. The candidate can expect short research stays at Aarhus University and DIS/CREADIS, and an external mobility at another university in Europe.

For further information about scientific aspects of the stipend, please contact Associate Professor Morten Christensen by mail: mlc@bio.aau.dk  

The Department of Chemistry and Bioscience advances regional, national and global knowledge build-up, while contributing to the solution of societal tasks through innovative research, problem-based education and knowledge-based collaborations. We produce high-quality research in engineering and natural science and Aalborg University constantly ranks top of the World within engineering research and education. The Section of Chemical Science and Engineering has a clear goal of being the go-to partner for regional, national and international industries in need of research based knowledge and support for transition of classic chemical production to sustainable and more bio-based production processes and promote the green transition of society.

PhD stipends are allocated to individuals who hold a Master's degree. PhD stipends are normally for a period of 3 years. It is a prerequisite for allocation of the stipend that the candidate will be enrolled as a PhD student at the Doctoral School of Engineering and Science in accordance with the regulations of Ministerial Order No. 1039 of August 27, 2013 on the PhD Programme at the Universities and Certain Higher Artistic Educational Institutions. According to the Ministerial Order, the progress of the PhD student shall be assessed at regular points in time.

Shortlisting will be applied. This means that subsequent to the deadline for applications the head of department supported by the chair of the assessment committee will select candidates for assessment. All applicants will be informed whether they will be assessed or not.

For further information about stipends and salary as well as practical issues concerning the application procedure contact Ms. Vigdis Skomager-Bohnfeldt, The Doctoral School of Engineering and Science, email: vkns@adm.aau.dk   phone: +45 9940 7408.
