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 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).

Can polyacrylamide be used to treat pulp and paper mill wastewater?

SVI values of less than 70 ml g −1 are found for all polyacrylamide at their respective optimum dosage. Based on the cost evaluation, the use of the polyacrylamides is economically feasible to treat the pulp and paper mill wastewaters.

Which cationic polyacrlyamide has the highest flocculation efficiency?

Cationic polyacrlyamide Organopol 5415 with very high molecular weight and low charge density is found to give the highest flocculation efficiency in the treatment of the paper mill wastewater.

Can polyacrylamide be used alone in coagulation–flocculation process?

Based on the cost evaluation, the use of the polyacrylamides is economically feasible to treat the pulp and paper mill wastewaters. This result suggests that single-polymer system can be used alone in the coagulation–flocculation process due to the efficiency of the polyacrylamide.

Which coagulant–flocculant scheme is used in papermaking-reconstituted tobacco slice wastewater treatment?

According to our previous studies, PAC coupled with a CPAM with very high molecular weight and low charge density was selected as the coagulant–flocculant scheme for the coagulation–flocculation process of papermaking-reconstituted tobacco slice wastewater treatment.
