We are looking for a teaching assistant, which is a blend of teaching practicals for Bachelor and Master classes and performing research to obtain a PhD. The PhD topic is "Advanced control for sustainable resource recovery systems", under the guidance of professor Elena Torfs.

Deadline:

You will be working on a 1-year research project in collaboration with the Flemish drinking water utility De Watergroep. The project focusses on the development of a framework for automatic calibration and uncertainty analysis of digital twins for leak detection in drinking water networks. Your specific tasks include:

  • Conduct a literature review on state-of-the-art calibration methodologies.
  • Make an inventory among international drinking water utilities of the application and calibration of hydraulic models.
  • You will develop an open python package for automatic calibration of EPAnet drinking water network models. This framework will include:
    • Sensitivity analysis to determine the most important sources of uncertainty in a calibration exercise (ex. pipe roughness factors);
    • Definition of physical constraints on the calibration algorithm (ex. flow-pressure relation);
    • Implementation of a parameter optimization algorithm (ex. genetic algorithms);
    • Identifiability analysis on the estimated model parameters.
  • If needed based on the identifiability analysis you will look into model reduction strategies such as skeletonization.
  • You will develop a methodology for the propagation of important sources of uncertainty in a hydraulic model.
  • You will apply and test your methodology to a case-study in the north-east of Belgium.

et Departement Chemie/Biochemie van de Faculteit Toegepaste Ingenieurswetenschappen zoekt een voltijdse (100%) doctoraatsbursaal in het domein van de biologische zuivering van industrieel afvalwater

Functie

  • Je werkt actief aan de voorbereiding en verdediging van een doctoraal proefschrift in het domein van de biologische zuivering van industrieel afvalwater. Het doctoraatsproject handelt specifiek over de biologische verwijdering van fosfaat uit industrieel afvalwater, via het zogenaamde EBPR proces (Enhanced Biological Phosphorus Removal). We richten ons hier op het fosfaatrijke afvalwater uit de aardappelverwerkende industrie. Specifieke onderzoeksvragen zijn (1) is biologische fosfaatverwijdering mogelijk met dit type afvalwater?, (2) hoe kan EBPR optimaal geïntegreerd worden met de verwijdering van stikstof uit het afvalwater, en (3) welke micro-organismen zijn hiervoor verantwoordelijk? Het project gebeurt in nauwe samenwerking met de industrie
  • Je publiceert wetenschappelijke artikelen die verband houden met het onderzoeksproject.
  • Je neemt een beperkt pakket van onderwijs- en onderzoeksondersteunende taken op voor de vakgroep biochemische ingenieurstechnieken.

We are looking for a highly motivated postdoctoral researcher with an interest and affinity for process engineering to work on the development of novel mixed culture microbial processes for resource recovery. The selected candidate will work on the Thermomel project, a research project funded by the European Space Agency (ESA) to investigate the bioenergetics of acidogenic fermentations within the first compartment of the MELISSA (Micro-Ecological Life Support System Alternative; Melissa Foundation). Specifically, the researcher will investigate the conversion of carbohydrates in acidogenic fermentation conditions & the metabolic pathways involved.

The adsorption team of the Department of Chemical Engineering (Vrije Universiteit Brussel, Belgium) is looking for a PhD researcher to research the adsorptive separation of oxygen-rich gaseous streams emerging within a novel integrated carbon utilization process, this in the scope of a VLAIO funded project involving multiple partners. The focus is on fabricating and testing adsorbent structures for their oxygen separating performance: (I) formulating, shaping, characterizing adsorbents and (II) evaluating these for oxygen recovery (cyclic experiments, process modelling). To this purpose, you can make use of the available setups, synthesis knowhow and tools, and modelling expertise within the team.

The adsorption team of the Department of Chemical Engineering (Vrije Universiteit Brussel, Belgium) is looking for a PhD researcher (targeting a Baekeland project) to research drying of gaseous flows using pressure swing adsorption (PSA) techniques, together with a large world-wide company active in Belgium. The focus is on fabricating, characterizing and testing novel adsorbent structures in a PSA application, from lab to pilot scale. A significant portion of the work involves simulation and process modelling. To this purpose, you can make use of the available setups (including pilot), synthesis knowhow and tools, and modelling expertise and software within both the university as company.

The adsorption team of the Department of Chemical Engineering at the Vrije Universiteit Brussel aims at the development of separation processes for a sustainable chemistry. In this project, we will develop new processes for CO2 capture. In this large, multidisciplinary and multi-partner project, new processes for intensified CO2 capture will be studied. At the Vrije Universiteit Brussel, we will develop and study new adsorptive processes based on the use of alternative heating and regeneration methods. This includes both modeling and experimental work. The team of Prof. Denayer has extended know-how in the field; the well-equipped research lab contains all possible tools for the in-depth study of adsorption separation processes.

The adsorption team of the Department of Chemical Engineering at the Vrije Universiteit Brussel aims at the development of separation processes for a sustainable chemistry. In this project, we will develop new processes for the recovery of valuable chemicals from renewable resources (lignin oil). In this multi-partner project, new catalytic and separation processes are studied. At the Vrije Universiteit Brussel, process models for the downstream processing of the lignin oil have to be developed using Aspen Plus. The duration of this project is 1.5 years. The team of Prof. Denayer has extended know-how in the field; the well-equipped research lab contains all possible tools for the in-depth study of adsorption separation processes.

The adsorption team of the Department of Chemical Engineering (Prof. J. Denayer) at the Vrije Universiteit Brussel aims at the development of better and sustainable separation processes. In the present project, an industrial Pressure Swing Adsorption (PSA) process is optimized. A fully equipped 2-bed pilot PSA unit is available in the research unit, allowing to obtain very accurate data for the cyclic separation process. In this project, pilot plant tests will be combined with detailed modeling of the PSA process to achieve an improvement of process performance in terms of power consumption, productivity etc. Besides, a full characterization of the adsorption properties of the materials used in this separation will be carried out via a range of experimental methods (gravimetry, volumetry, calorimetry, porosimetry,…) available in the research group.
