Abstract
Conditioning studies were conducted on several water and

wastewater sludges using polymers to determine the effect of

high-intensity mixing on floc formation and breakup. Mechanisms

acting in particle coagulation were also investigated.

A rapid mixing apparatus was used in conditioning the

sludge to simulate the high velocity gradients encountered

in most dewatering equipment. Anionic and cationic polymers

of varying molecular weights and an inorganic coagulant were

chosen as the conditioning agents. Dewatering rates were

measured by the capillary suction time (CST) apparatus. The

effect of rapid mixing on the polymer efficiency was evaluated

by premixing the polymer, using the same mixing apparatus,

prior to applying it to condition the sludge.
