Process intensification

Leader: José SANCHEZ

Objectives:

To develop the integration of membranes into processes, as independent processes of separation/extraction/purification/concentration (for gas separation, microfiltration, nanofiltration, etc) or as coupled and/or multi-functional processes (membrane bioreactor, enzymatic membrane reactor, advanced oxidation, adsorption). Through the use and development of multi-scale analysis and modeling tools, our methodology is based on the observation, quantification and modeling of transfers and reactions (chemical, photochemical, enzymatic or biological ones) to intensify a given process and to propose some innovative processes which would be efficient, sure, easy to control, compact, with a low energetic cost and a low environmental impact.

Technical support:

- Analysis: HPLC ; Gas chromatography ; Flamme atomic absorption ; Spectrophotometer UV-Visible (+Peltier) ; COT-meter ; NH_4+/NO_x online probes.

- Semi industrial pilot units: Enzymatic membrane reactor ; membrane bioreactor ;  

Projects actually developed:

- Enzymatic Membrane Reactor (REM)
- Membrane BioReactor for wastewater treatment.
- Separation / selective extraction in aqueous solutions by porous membranes
- Coupling of membrane and advanced oxidation process (AOP)
- Catalytic ozonation of industrial effluents
- Oxydation of membrane filtration retentates for wastewater reuse
- Coupling of membrane with sorption
- Membrane contactors
- Macroporous membranes ("breathing" membranes)
- Modeling the coupling of membrane and high temperature electrolysis

Oxidation of membrane filtration retentates for wastewater reuse

Today water resources drinkable are more and more weak and fragile. One of the solutions, to meet the needs in waters is to reuse waters after waste water treatment plant (WWTP). At present, the (...)
