Project
Towards more cost efficient water reuse through MBRs (MembraneBio-flocculation-Reactors).
Biodegradation by activated sludge is the most cost efficient way of
wastewater treatment. To make water suitable for reuse, filtration can
be integrated with this biodegradation in so-called membrane
bioreactors.
Membrane bioreactors (MBRs) offer several advantages
including an effluent of high quality, higher degradation rates, lower
sludge production and a smaller surface area per plant. Membrane fouling
remains the main problem. This membrane fouling increases the operating
cost of an MBR drastically and must be better understood in order to
have a better process control.
Using an integrated approach, driven
by the findings that bioflocculation has a major impact on membrane
fouling, this project focuses on the cost efficiency of MBRs in an
industrial water reuse context. The rationale of the project is
reflected inthe statement that membrane bioreactors should actually be
membrane bio-flocculation-reactors. With a comprehensive set of
monitoring tools, new insights in bioflocculation are obtained. Finally,
these new insights will be indications for the optimal operational
parameters to strongly reduce membrane fouling.
