This course teaches the basics of microfluidic technology and samples a range of applications in microbiology and chemistry, all through hands-on experience and live demos.
Hydraulic resistance of membrane biofilms: effect of extracellular polymeric substances
Bacteria inevitably colonize membrane filtration systems to form biofilms. The formation of biofilms on membrane surfaces reduces permeate flux due to the increased hydraulic resistance. But practical experience indicates that avoiding the formation of biofilms is almost impossible. Eawag has thus developed a new paradigm for the operation of membrane systems, which consists in taking advantage of biofilms formed on membrane surfaces. The biofilm present controls both the quantity and quality of the permeate.
The main objective of the proposed master thesis is to identify the causality link between the biofilm composition and the hydraulic resistance of membrane biofilms.
This master thesis is in collaboration with Eawag (Dr. Nicolas Derlon and Prof. E. Morgenroth). The work will mainly be conducted at ETH.
