Which polyacrylamide has a good flocculation efficiency?

Flocculation performance of four kinds of polyacrylamide (PAM) with different chain end group, namely, PAM, star-PAM, PGS-PAM and Al (OH) 3 –PAM hybrids, in Kaolin suspensions have been investigated by Spectrophotometer. It was found that their flocculation efficiency deceases in the order: PGS-PAM –PAM PAM.

Can polyacrylamide grafted hydroxypropyl methyl cellulose be used as flocculant?

Effect of flocculants for the treatment of mining industry wastewater. 4. Conclusion Based on the observed results, it can be concluded that polyacrylamide grafted hydroxypropyl methyl cellulose may be used as high performance flocculant for treatment of synthetic effluents and mine wastewater.

What are the different types of polyacrylamide flocculants?

1. Introduction It is well known that polyacrylamide (PAM), which is a type of water-soluble polymer, is widely used in industrial wastewater treatment as a flocculant , . In general, these flocculants can be divided into three groups, depending on the nature of their charge, i.e., cationic-PAM, anionic-PAM and non-ionic-PAM.

Is HPMC-G-Pam a good flocculant?

The flocculation performance of HPMC-g-PAM has been investigated using standard turbidity test as well as settling test methods and finally the efficiency of the graft copolymer as flocculant has been studied in mine wastewater.

What are grafted polysaccharide based flocculants?

Several grafted polysaccharide based flocculants including amylopectin , carboxymethyl cellulose , chitosan , glycogen , guar gum , starch , and tamarind kernel polysaccharide have been reported as efficient flocculants for the treatment of industrial wastewater and synthetic effluents.

Can cnpam flocculate kaolin suspension?

The CNCs content in the CNCs/PAM hybrid (CNPAM), hybrid dosage, and pH value were optimized. We further studied the effects of stirring speed and time as well as sedimentation time on the flocculation behavior. Under optimal conditions, the CNPAM flocculant could effectively flocculate kaolin suspension with a transmittance of >93%.
