A rotary drum filter with 30 percent submergence is to be used to filter a concentrated aqueous slurry of CaCO3 containing 14.7lb of solids per cubic foot of water (236 Kg/m³). The pressure drop is 1414 lb/ft². Calculate the filter area required to produce 0.302 lb/s CaCO3 from the slurry with a concentration of 19.24 lb/ft³ when the filter cycle time is 5 min. The viscosity of the slurry is 6.72*104 lb/ft s and the cake resistance is 2.9*1010 ft/lb. The filter medium resistance is negligible and the working temperature is 20 C Given data: Ap=1414 lb/ft²; f-0.3; a= 2.9 10¹0 ft/lb; Tc = 300 s; mc-0.302 lb/s; C-19.24 lb/ft Ans: 320 ft² A rotary drum filter with 30 percent submergence is to be used to filter a concentrated aqueous slurry of CaCO3 containing 14.7lb of solids per cubic foot of water (236 Kg/m³).
