| Abstract | ||
| In this work, the focus was done on the study of the transport and absorption of Iron metal (heavy metal) through various multiple porous media. A physical model of a laboratory system similar to the filters system was established consisting of a 4-meter pipe, each meter of which is placed in a specific type of soil, which are sandy, organic, calcareous and sandy gravel soil respectively. The characteristics and the adsorption of the media were tested and the pollutant was prepared and pumped as an aqueous solution through the physical model continuously for more than 50 hours. The results showed that the adsorption process and consequently the removal efficiency are higher in the first porous medium contained in the first part until the saturation is near. Then the second media begin to play the major role for the adsorption and the removal efficiency and so on for the third and fourth media respectively. The results also showed that the adsorption efficiency depends on the arrangement and type of the porous medium. The system of a multiple porous medias provides a very good technique to getting rid the heavy metals with a very low cost. | ||
