Is cationic polyacrylamide emulsion a flocculant for paper mill wastewater treatment?

" Cationic polyacrylamide emulsion with ultra-high concentration as a flocculant for paper mill wastewater treatment ," BioRes. 15 (2), 3173-3189. Cationic polyacrylamide emulsions prepared with ultra-high concentration (CPAME-uhc) have the advantages of fast dissolution, convenient operation, and low transportation cost.

Why is cationic polyacrylamide important?

Because of its wide application, it is an important synthetic water-soluble polymer. Traditional cationic polyacrylamide powder products have many problems associated with their application, such as difficulty of dissolving, slow dissolution speed, and the need for large dissolution equipment, etc.

Can cationic polyacrylamide emulsions with ultra-high concentration save transportation costs?

Cationic polyacrylamide emulsions with ultra-high concentration (CPAME-uhc) can obviously save transportation costs, but their molecular weight, solubility, and temperature/salt resistance need to be further improved. Therefore, this study attempted to improve the molecular weight of CPAME-uhc by optimizing the preparation conditions.

What is cationic polyacrylamide (CPAM)?

Cationic polyacrylamides (CPAMs) are widely utilized due to their excellent performance in flocculation and sludge dewatering . Numerous studies have been conducted on CPAM synthesis technologies, including grafting, free radical polymerization, and polymer modification .

Are cationic copolymers used in sludge dewatering?

Four groups of synthesis technologies of cationic copolymers were reviewed, including aqueous solution polymerization, dispersion polymerization, inverse emulsion polymerization and photo initiated polymerization. Furthermore, the paper reviewed that the application of cationic flocculants in sludge dewatering treatment.

Does microblocked polyacrylamide improve municipal sludge dewaterability?
