Fouling in Membrane Filtration Systems

Project Description

In the last decades the use of membrane systems for fresh water production has increased strongly to supply the growing water demand due to increasing human population, industrial and agricultural activity, economic growth and urbanization. Fouling represent one of the major drawbacks of membrane systems. In this project, we aim to explore different techniques in order to study the fouling developed in the system and relate with the membrane performance decrease. ​

About the
Researcher

Johannes Vrouwenvelder

Professor, Environmental Science and Engineering<br/>Director, Water Desalination and Reuse Center<br/>

Johannes Vrouwenvelder

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.

Desired Project Deliverables

​The student will learn various approaches to characterize the fouling developed in membrane filtration systems. He/She will learn different techniques (i.e. Confocal, Flow Cytometry, ATP, SEM, LCOCD etc). Several experiments will be run in order to relate the fouling developed in the system with the overall performance.
