Calculate the amount of pebbles required for the following data. Flow: 200 m3/h Velocity of dual media filter: 15m/h Height: 0.6 m

Calculate the amount of pebbles required for the following data. Flow: 200 m3/h Velocity of dual media filter: 15m/h Height: 0.6 m Correct Answer 12668 Kg

First the diameter is calculated by finding the area. Area= 200/15. Diameter= square root (1.27 × 13.33) = 4.11. Amount of pebbles equals πd2/4. This equals 0.785 x 4.11 x 4.11 x 0.6 x 1600 = 12668 Kg.

A rotary drum filter with 30% submergence is used to filter concentrated aqueous slurry of calcium carbonate containing 15lb of solids per cubic foot of water. The pressure–drop is 2011Hg. If the filter cake contains 50% mixture (wet basis), calculate the filter area required to filter 10 gal/min of slurry. The filter cycle time is 5 min. The specific cake resistance depends on the pressure–drop as: α (ft/lb) = α (Δp)0.26, where α = 2.90×1010 Viscosity of the filtrate = 6.72×10-4 lb/ft-s. Density of calcium carbonate = 168.8 lb/ft3. Neglect filter medium resistance.
