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 20<sup>11</sup>Hg. 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:<br> (ft/lb) = ( p)<sup>0.26</sup>, where = 2.90 10<sup>10</sup>
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?
