英文摘要	In Morocco, many regions suffer from water scarcity. In order to address the arid zone water shortage in the Marrakech region, the reuse of wastewaters in agriculture can present new alternatives. However, there are significant concerns about the safety of wastewater reuse especially for irrigation purposes that can be insured by reducing the wastewater pollutants amount by accessible and inexpensive processes like slow sand filtration (SSF). In order to study the removal efficiency of SSF, a continuous fixed-bed adsorption study was achieved by using sand as an adsorbent of metallic trace elements (Cd, Cu, Pb and Zn) from contaminated water of Tensift River. This river received wastewater directly from industrial unit of Zn and Pb extraction of Draa Lasfar mine located at 13 km in north-west of Marrakech City in Morocco. Results showed that SSF can remove 100% of metallic pollutants and the removal efficiency of this process to decontaminate water depends greatly on the sand bed height (filter). Thus, the long filter eliminates more pollutants than the smaller ones. This result can be attributed to the exposition of new fixation sites of metallic pollutants on the sand surface that facilitates their adsorption process. The dynamic behavior of adsorption mechanism used in SSF process is predicted by using Langmuir kinetics of adsorption-desorption with no axial dispersion.
