AB  - In this study, the possibility of using wastes of construction, especially, the waste of granite in water
filtration is considered. A pilot plant is designed consisting of two columns, the first one is a sand filter which
is used for comparison while the second one is the assigned granite filter. The pilot plant was run for two times,
the first run was carried out with filtration rate of 5 m/h, pH of 7.6, Total Dissolved Solids (TDS) of
595 ppm, Temperature (T) of 30°C and Electrical conductivity (Ec) of 1193 μS/cm while the second run was
carried out with filtration rate of 7.5 m/h, pH of 7.8, TDS of 621 ppm, Ec of 1237μsec/cm and T of 31°C. The
maximum values of turbidity removal efficiency corresponding to first run for sand and granite filters are 84.89
and 84.12, respectively while the maximum values of turbidity removal efficiency corresponding to second run
for sand and granite filters are 80.66 and 74.77, respectively. The results show that the maximum values of
removal efficiency of Total Suspended Solid (TSS) corresponding to first run are 84.77 and 82.44 for sand and
granite filters, respectively while the maximum values corresponding to second run are 80.55 and 76.68 for sand
and granite filters, respectively. The results corresponding to both runs demonstrate that the removal efficiency
of turbidity and TSS of granite filter approach the removal efficiency of sand filter, thus, it can be deduced that
the granite filter yields satisfactory results as a filter media.
