Abstract

The physical and fluidization characteristics of river sand from Masaya, Bay, Laguna and Cuyab, San Pedro, Laguna and white sand from Matukad, Caramoan, Camarines Sur were determined. Bulk density (1.74 g/mL) and particle density (2.75 g/mL), hence apparent specific gravity and real specific gravity of the Camarines Sur sand was the highest among the three sands. All three sands may be considered as fine sand in terms of effective diameter obtained, which ranged from only 0.13 mm to 0.18 mm. Uniformity coefficient ranged from 1.85 to 2.52, indicating that the raw sand samples were not well-graded. Each of the sand samples were sieved to two size grades of 0.600 to 0.850 mm and 0.106 to 0.425 mm to determine their fluidization characteristics for potential use as fluidized bed sand filter media. The particles with relatively smaller sizes fluidized first before the ones with larger sizes. The difference in hydraulic fluxes was significant for the 0.600 to 0.850 mm sands at 0% fluidization. It was also significantly different for the 0.106 to 0.425 mm sand samples. The San Pedro sand had the highest hydraulic flux requirements to achieve a specific fluidization percentage , while the Camarines Sur sand required the lowest.
