Project Description

Membrane filtration plays an important role in seawater desalination and wastewater reclamation. Biofouling is an unacceptable loss of performance caused by the growth of bacteria inside the membrane element. The aim of the project is to establish relations between operational conditions, such as water velocity, production rate and nutrient concentration and the growth rate of biofilms. The results will allow better understanding and control of biofouling formation. The two main methods to observe the thickness of the biofilm are via its hydraulic resistance and via optical coherence tomography (OCT). ​

Education Profile

  • Ph.D., Biotechnology, Faculty of Applied Sciences, Delft University of Technology, The Netherlands, 2009

Research Interests

a€‹Professor Vrouwenvelder studies microbiological and process technological aspects of water treatment and transport. This includes fouling control of membrane systems and cooling towers, and sensors and tools for biofouling/biofilm monitoring and rapid sensitive microbial water quality monitoring. Additionally, Professor Vrouwenvelder performs numerical modelling of fouling and water treatment system performance, and studies the dynamics of the microbial ecology of water distribution systems.
