title: Effect of aggregate size and structure on specific resistance of biosolids filter cakes.
abstract: Investigation of the specific resistance to filtration of biosolids modified by cationic polymer addition reveals a dependence on both size and structure of the resulting biosolids flocs. This dependence is reasonably described by a modified form of the Carman-Kozeny equation and reveals that effects of differences in floc structure on cake resistance are most marked for flocs of small size. Conversely, effects of differences in floc size are most significant when flocs are more compact.
