Process intensification

Leader: José SANCHEZ


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.

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 (...)
