What is cationic polyacrylamide CPAM?

Cationic polyacrylamide CPAM is a linear polymer copolymerized by cationic monomers and acrylamide. It is used as dewatering agent with the functions of decolorization, adsorption, turbidity removal and adhesion. 3. highly effective dispersant. Your data is always safe with us.

What is cationic polymer flocculant?

Cationic Polymer Flocculant is the initiator of the physicochemical process of adhesion of small particles of dispersed systems to larger ones under the influence of adhesion forces with the formation of coagulation structures and the formation of an enlarged sediment.

Does cationic-polyacrylamide promote humic acid removal?

The combination of organic and inorganic coagulants is considered to be an effective strategy for Humic Acid (HA) removal. In this study, the performance of Titanium-based coagulants aided by Cationic-Polyacrylamide (CPAM) to HA molecules was compared. It was found that CPAM had a higher promotion effect in the TXC system.

How does CPAM affect the surface structure of a floc?

The addition of CPAM further enhanced the adsorption of particles on the surface of the floc, more hydrolysates were adsorbed on surface. In addition, the addition of CPAM densified the rough surface structure, which could be due to the strong bridging effect of CPAM. (Fig. 5 ). Fig. 5. SEM images of flocs with or without CPAM.

Can polyacrylamide be used as a coagulant in humic acid-kaolin water treatment?

Drinking water treatment by stepwise flocculation using polysilicate aluminum magnesium and cationic polyacrylamide J. Environ. Chem. Eng., 7 ( 2019), Article 103049 Polyacrylamide as coagulant aid with polytitanium sulfate in humic acid-kaolin water treatment: effect of dosage and dose method

Does cationic-polyacrylamide increase zeta potential of inorganic coagulants?

The use of Cationic-Polyacrylamide as a flocculant significantly increased the zeta potential of inorganic coagulants ( Fig. 2). Thus, the addition of CPAM in three coagulants was observed more effective in fluorescence quenching of HA-like organics, which indicated that CPAM promoted the effective removal of HA.
