  • The effect of polyacrylamide charge density and

    2006-12-1 · In the present study, the loss of bridging and strong adsorption for the low molecular weight and high surface charge cationic polymer (i.e., C 446) allows most of the primary flocs to remain in suspension and additionally has more resistance to consolidate, so that a less compact sediment is produced during the centrifugation process because of the poor flocculation.
