Résumé:
The presence of heavy metals in a large number of rejection constitutes a major concern for
the public autorities from the fatal conséquences bieng able to take place on the environment what
makes their treatement imperative
The objective set in this work is to evaluate the effectiveness of zéolithe Na-X and polymeric
membranes containing « starch and bentonite with activated carbon addition » opposite the
elimination of cadmium and lead.An experimental study of the influence of some parameters was
carried in order to allow the optimisation of the retention of the both metals.
The results of this study show that the both processes studied prove to be efficient ways
opposite the depolltion of water charged of heavy metals.Zéolithe Na-X present satisfactory
performance of retention for cadmium and lead compared to the polmeric membranes
