Research on a new cationic polyacrylamide (CPAM) with a cationic microblock structure and its enhanced effect on sludge condition and

Flocculation is one of the commonly used sludge conditioning methods in water supply plants, which can improve the sludge dewatering performance by reducing the specific resistance of sludge (SRF), decreasing the amount of sludge, and finally lowering the transportation cost and subsequent disposal cost of sludge.

The impact of polyacrylamide flocculant solution age on flocculation performance - ScienceDirect

The polyacrylamide dosages required to achieve measurable flocculation decreased as the flocculant age was increased, with optimal performance attained at 72 h. Flocculation using a 1-h-old flocculant solution consumed 75% more polymer than with an optimally prepared stock solution.
