Embodiment 1
[0090] Three formulations of an anionic polymer, labeled Products A, B and C, were tested for their ability to aggregate into slurries to determine which was most suitable for in-line injection into solid-liquid applications using the Dynafloccer device. These formulations are listed in Table 1 below. Product A is figure 1 Products reviewed.

[0109] 1The composition is listed in Table 1
[0110] Comparing at a settling velocity of 10 in / min, these data show that the fast converting / dispersing anionic polymer Product A containing 3.5% ethoxylated octylphenol outperforms Products B and C by about 40%. Visually, Compound ...
Embodiment 3
[0114] Products A, B, and D were evaluated on two coal slurries, the compositions of which are shown in Table 1, using a Koflo(R) in-line static mixer. The sedimentation velocity of the slurry was analyzed using a Clarometer(R) manufactured by Ramsey Technology Inc., Minneapolis, Minn. From these data, the replacement ratio, referred to as "RR", was determined.
[0115] The displacement ratio is an indication of the efficacy of the polymer, ie how much polymer is required to achieve a certain level of performance compared to a control (benchmark). Here, the displacement ratio is the ratio of the amount required to rapidly convert the polymer to product D, the standard polymer in this study, on the basis of the same active species. The performance level chosen was a Clarometer(R) reading of 105.
