Examination of technical literature reveals a potential use of combined water purification via physical, chemical and biological processes integrating the most recent techniques. The main goal of this research, concerning topics no 4.3.3 and 4.4.4 of the Brite programme, is to set up new multisectorial and cost effective, biological and membrane processes.
The originality of the approach consists of proposing new separation techniques which can easily be integrated in reaction systems and improve mass transfer while limiting the clogging and/or contamination risks. Technological progress is based on : the use of bacterial species capable of assimiling heavy metals and degrading the micropollutants present in industrial effluents of various origins; dyeing plants, surface treatments, non-ferrous metals, rainwater, lixiviation extracts in released products, etc...
The efficiency of aquatextile and composite membranes integrated in type reactions : sedimentation on fibrous matrix, tangential filtration, absorption-filtration on a mobile membrane, flat sheet membrane and tubular membranes.
