Preparation, Characterization, and Sludge Conditioning of Cationic

Cationic polyacrylamide (CPAM) has been widely used for sludge conditioning because it can neutralize the surface charge of solid and bridge particles through its long polymer chain to form large flocs that can reduce the specific resistance and cake compressibility of sludge [4,5,6]. The molecular weight (MW) of CPAM, which can be characterized by intrinsic viscosity, is closely related to
