1- Industrial Wastewater Treatments (WWT) and Water Reuse/Recycling (WR) in Grenoble
Goals:
� Reducing excess sludge production

Context:
� In Europe, the production of excess sludge is exceeding 10 million tons of dry solids and forecasted to increase.
� Sludge management is about half of the operating costs.

1-2 Coupling Hydrodynamic/Biofilm in a biofilter:Multiscale approach
Key words: bioprocesses, biofilms experiments, modelling, coupling hydrodynamic-biomass
Goals:
� To understand relations betweenhydrodynamic and biofilm:

optimizise the design and to intensify the use
Context:
Biofiltration is a bioprocess with fixed-
biomass for wastewater treatment:
robust, compact, limited sludge
production, low functioning cost (energy),…
but with empirical design and operating
dysfunctionings mainly related to clogging
effect
limited development and use

� Biological kinetics are closure lawswhose structures depend on processesaveraged on the biofilm and at the reactor
scale. They integrate the biofilm response to environmental and hydrodynamical stess.
� Experiments at microscale required to derive these closure laws
