What will be your challenge? In this PhD trajectory, you will develop improved ion exchange membranes for electrodialysis applications in bio-based chemical process industry. Although the projectproposal has already been written, you will be expected to defend the proposal to obtain FWO funding for this PhD.
An experimental approach will be used to:
Your work will result in a prototype and a proof of concept for selected industrial cases.
Arguments in favour of a shift from petrochemical feedstock to alternative bio based chemicals are well-known. Bio-based chemicals are produced from the fermentation or direct transformation of natural feedstock (upstream processing). This is followed by several operational steps with the purpose of isolating and purifying target molecules (downstream processing). Electrodialysis provides an attractive alternative for existing separation technologies, e.g. ion exchange (IEX) and membrane filtration. It can provide cost-effective processing at higher concentrations compared to IEX while providing highly selective separations between charged and uncharged components. The latter is not the case when applying pressure-driven membrane filtration applications such as reverse osmosis (RO). Fouling however is a challenge when processing bio-based streams. This is due to the fact that these streams are typically highly complex mixtures. Therefore fouling is a recurring issue hampering effective implementation of electrodialysis in the bio-based chemical industry.
