Access is restricted indefinitely. ----- This study deals with the development of a hybrid process combining membrane filtration and adsorption or ion exchange for the treatment of secondary effluent for their reuse. The application of this process to the treatment of wastewaters requires looking for the lowest cost and developing a sustainable process (low energy consumption and use of regenerable sorbents). For this purpose, our study contained three main chapters.: • Research of an alternate material to the Powdered Activated Carbon PAC which is effective but non regenerable ; a comparative study of the kinetics and isotherms of adsorption of different materials was then performed. and resulted in the identification of an ion exchange resin. • Study of the hybrid process at lab scale and pilot scale using PAC and the Ion Exchange Resin. • Improvement of a protocol for the determination of the fouling potential of the treated water so as to get a quantitative information concerning its ability to be further treated by either nanofiltration or reverse osmosis for multi usage reuse.
