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: (ft/lb) = ( p)0.26, where = 2.90 1010
Filter aid can also be added to the fermentation broth to increase the porosity of the cake as it forms , what does this statement means?
