Cationic polyacrylamide (CPAM) is a linear polymer compound, which can affinity and adsorb hydrogen bonds due to a variety of lively groups. 

Cationic polyacrylamide is mainly a negatively charged colloid, which has the functions of turbidity, discoloration, adsorption, and bonding. 

Cationic Polyacrylamide is suitable for organic colloidal content in dyeing, paper, food, construction, metallurgy, mining, powder coal, oilfield, aquatic processing and fermentation, especially for the dehydration treatment of urban sewage, urban sludge, paper sludge and other industrial sludge.
