Abstract

Application of outflow water from treatment plants for irrigation purposes (as a non-usual water resource) is being developed due to a serious shortage of common water resources in Iran. Activated carbon as a conditioner in water treatment procedures causes undesired changes in hydraulic properties of such a porous media like soil, bringing about somehow its degradation. The effects of activated carbon concentration on hydrodynamic properties of a sandy soil were studied through a physical modeling. Variations of saturated HYDRAULIC CONDUCTIVITY, bulk density and porosity of the sandy soil were assessed for two categorical tests. First, flow of fresh water through a soil-carbon mixture of 1 to 7 percent (on a mass basis) and the other for a mixture of water-carbon of 0.5 to 2 percent (mass basis) through the sand. The results revealed that the saturated HYDRAULIC CONDUCTIVITY of sand decreased by 80 percent due to a mixing of 7 percent sand-carbon, reducing it 0.06 cm/s to 0.014 cm/s. Porosity was reduced from 0.44 to 0.426 and while bulk density being increased from 1.5 to 1.507 g/cm3. Also, a reduction of 91.5% and 6% in saturated HYDRAULIC CONDUCTIVITY and porosity, respectively, and an increase of 0.71% in bulk density were observed, due to flowing of water-carbon (concentration of 2%) through the sand column.
