Preparation of amphiphilic cationic polyacrylamide (CPAM) with cationic

Cationic polyacrylamide (CPAM) is a water-soluble linear polyelectrolyte with high molecular weight and positive charge density. Because of its low cost, high efficiency, and simple operation, CPAM is widely used as a chemical conditioner for flocculation pretreatment of sludge before mechanical dewatering (Sun et al. 2018; Zhou et al. 2014).

Research on a new cationic polyacrylamide (CPAM) with a cationic

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 main drawbacks of using Fenton's reagent or the common polymers such as cationic polyacrylamide (CPAM) for sludge dewatering are the high water content and the slow filtration rate. These drawbacks are unfavorable for the subsequent disposal and reutilization of the dewatered sludge cake (Liu et al., 2012b).
