The accurate estimation of flocs characteristics is valuable for evaluating water treatment performance under certain coagulation conditions. Synthetic organic polymers, such as polyacrylamide (PAM) and polydimenthydiallyammomium chloride (PDMDAAC), have been widely applied as flocculant aids in many industries, including thickening operations

The result indicates a move toward bridging flocculation mechanism for the higher molecular weight polymers as it is commonly observed that bridging flocculation results in flocs of large size. Fig. 1 also showed that the flocs aggregated by adding cationic PAM were larger than those formed by anionic PAM.

The repulsion between the negatively charged polymer and negatively charged surface of kaolin allows the primary amide functional groups of polyacrylamide to be extended to produce loops and tails, which lead to the formation of large and open-structured flocs (Gregory, 2005, McGuire et al., 2006).

The shorter the aggregation time was, the smaller the flocs produced for the same hydraulic conditions were. Another interesting discovery was that broken flocs that formed in shorter aggregation time had the capacity to completely recover, whereas those formed in a longer amount of time had rather worse reversibility of broken flocs.
