The pollution of natural waters is related to industrial and domestic waste, employment in agriculture pesticides and fertilizers. The purpose of the various treatments is to eliminate or reduce the quantity of pollutants in wastewater. This purification provides a solution to the insufficiency of water especially in the field of agriculture. Among the methods applied in this field, we mention: Traditional biological treatment, adsorption, electrodialysis and infiltration percolation. The process chosen for the wastewater used in our work is infiltration percolation. The effectiveness of this technique focuses on the study of a number of physicochemical parameters of wastewater and characterization of filtering mass. Different filtering mass used in this process are the raw titaniferous sand and sifted sand titaniferous also called black sand. Mineralogical and particle characteristics (size distribution curve, weight parameters, values deduced ...) of different type sand show a difference between the two massifs. For wastewater, the results for the different parameters before and after infiltration on both columns (major ions, BOD5, COD, suspended solids, ...) show a better performance for the titaniferous sifted sand.
