Cheryl Bertelkamp is a researcher on the drinking water treatment team which is part of the water systems and technology group. In December 2015, she completed her PhD, supervised by Professor Jan Peter van der Hoek (Delft University of Technology) and Professor Arne Verliefde (Ghent University). In this research, she examined the main removal mechanisms (sorption and biodegradation) of organic micropollutants during bank filtration. In addition, she developed a model which, on the basis of functional groups that occur in the molecular structure of an organic micropollutant, can predict whether or not this substance is biodegraded during bank filtration. Cheryl has experience setting up experiments to simulate soil sinking, modelling organic micropollution patterns in columns and many analysis techniques. At KWR, Cheryl works on several projects such as research into: pyrazole, nano particles and nano-modified membranes, natural organic material (NOM) removal with (open) nano filtration membranes, the robustness test, the biological processes in activated carbon, underground water purification, modelling iron and manganese removal in quick filters, and exploratory research into resilient cities.
