Question: A rotary vacuum drum filter having a 30 % submergence of the drum in the slurry The solids concentration in the CaCO3 slurry is CF

A rotary vacuum drum filter having a 30 % submergence of the drum in the slurry The solids concentration in the CaCO3 slurry is CF = 14.7 lb solids/ft3 slurry Filter cake contains 50% moisture (wet basis) The filter cycle time is 5 min delta P = 20 in. Hg = 1414 lbf /ft2 The specific cake resistance = 2.9 x 1010 P 0.26 Assume Rm = 0 ps = 168.1 lb/ft3 For water: p= 62.3 lb/ft3 , u = 6.72 10-4 lb/ft.s mc = 0.302 Ib/s Calculate the filter area required to filter 10 gal/min (= 0.0022 ft3 /s) of slurry
