Example 1: A rotary drum filter with submergence is used to filter a concentrated aqueous slurry of containing of solids per cubic foot of water. The pressure–drop is 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:
Viscosity of the filtrate . Density of .Neglect filter medium resistance. Answer: Re–call the expression for the production rate of cake.
Here, production rate of cake
