V. BULK DENSITY OF POWDERED CARBON
Bulk density is important when powdered carbon is removed from the treated waste water by filtration because it determines the weight of carbon that can be contained in a filter of given volumetric solids capacity. When two carbons differing in bulk density are used at the same weight of carbon required per gallon per gallon, more gallons can be filtered with higher density carbon before the available cake space is full. Since cleaning and restarting a filter is expensive , the dense carbon permits less filter down time cost [118].
Bulk density is important when the carbon is removed by settling, which is the more common practice in water treatment. A carbon with a higher bulk density will provide a fast settling rate and volume of sludge which have to be handled or dewatered will be less.

The ideal activated carbon would have the maximum amount of internal surface with ample volume in the pores to hold the maximum weight adsorbed material. Due to its great porosity, ac...
