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.

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.

What is polyacrylamide (PAM)?

Enteromorpha prolifera polysaccharide based coagulant aid for humic acids removal and ultrafiltration membrane fouling control Polyacrylamide (PAM) has been used as a coagulant aid in water treatment process for past decades, but it has caused great damages to human nervous system.

What is cationic polyacrylamide (CPAM)?

Cationic polyacrylamide (CPAM) is a linear macromolecule compound. Because of its various active groups, it can adsorb many substances to form hydrogen bonds (Ma et al. 2017; Li et al. 2018).

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.

Which cationic polymer emulsion has the highest molecular weight?

When the amount of crosslinking agent was 0.4 ppm, the molecular weight of CPAME-uhc was the highest. When the amount of crosslinking agent exceeded 0.6 ppm, the molecular weight of cationic polymer emulsion decreased obviously.
