 in filtration plants all over the world and in Nigeria. The sand was subjected to various soil mechanics and hydraulic tests including Particle Size Distribution, Specific Gravity, Acid solubility, Porosity, Permeability and Filterability. The study shows that, sand from river Asa have Effective size (Es) of 0.40 mm; Uniformity coefficient (Uc) of 1.25; Acid solubility (%) of 2.10; Specific Gravity of 3.77; Porosity (%) of 51; Permeability (cm/sec) of 1.06. The maximum head loss obtained from river Asa sand with hydraulic Loading rates of 6.45 m/hr and 9.65 m/hr at 16 and 13 hours of filter run time were 19.014 cm and 24.347 cm of water. The results obtained for filter quality of the Asa river sand with turbidity of 32 NTU and hydraulic loading rates of 6.45 m/hr and 9.65 m/hr at 16 and 13 hours of filter run times were 4.52 NTU and 4.87 NTU, which were well below the recommended value of 5.0 NTU. The Specific objective of the study was achieved and the study shows that, sand from river Asa have potential properties to be used as filter media due to its properties were encouraging.&picture=http://www.aascit.org/aascit/decorators/img/journal/924.jpg)

This study investigated the Potential use of sand from River Asa at Ilorin, kwara State in North- Central Nigeria as filter media in water treatment plants. Sand is mostly widely employed as porous substance (Filter Medium) in filtration plants all over the world and in Nigeria. The sand was subjected to various soil mechanics and hydraulic tests including Particle Size Distribution, Specific Gravity, Acid solubility, Porosity, Permeability and Filterability. The study shows that, sand from river Asa have Effective size (Es) of 0.40 mm; Uniformity coefficient (Uc) of 1.25; Acid solubility (%) of 2.10; Specific Gravity of 3.77; Porosity (%) of 51; Permeability (cm/sec) of 1.06. The maximum head loss obtained from river Asa sand with hydraulic Loading rates of 6.45 m/hr and 9.65 m/hr at 16 and 13 hours of filter run time were 19.014 cm and 24.347 cm of water. The results obtained for filter quality of the Asa river sand with turbidity of 32 NTU and hydraulic loading rates of 6.45 m/hr and 9.65 m/hr at 16 and 13 hours of filter run times were 4.52 NTU and 4.87 NTU, which were well below the recommended value of 5.0 NTU. The Specific objective of the study was achieved and the study shows that, sand from river Asa have potential properties to be used as filter media due to its properties were encouraging.
