For flocculants based on a polyacrylamide (PAM) backbone, it is generally stated that increasing MW will lead to improved adsorption and settling performance ( Caskey and Primus, 1986, Clark et al., 1990, Petzold and Herrington, 1990 ), although this can be affected by many other factors.

Flocculating oil sands tailings with dual anionic/cationic polymers

[6, 7] Anionic polyacrylamide (PAM) is the most common flocculant for MFT, but when used alone it cannot recover much of the water trapped in the thick MFT slurry. [1, 8, 9] Even though modified PAMs and other new polymer flocculants have been used to improve MFT dewatering, they often need high doses, which limits their scale up. [6-8]

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.

3.3.2. Characteristics of slime water. The main characteristics of slime water were as follows: high concentration, high content of fine particles, high ash content, many negative charges on the surface of particles. These particles kept stable dispersion in the water due to the repulsion of the homoelectric charge.

Synergistic effects of surfactant-flocculant mixtures on ultrafine coal dewatering and their linkage with interfacial chemistry

Dioctyl sodium sulfosuccinate (AD) as an anionic surfactant, cetyl trimethyl ammonium bromide (CTAB) as a cationic surfactant, and an anionic polyacrylamide as a flocculant were used. Applied chemicals structures have been shown in Table 1.

Polymer Flocculants | SpringerLink

Polymer flocculants are water-soluble polymers which can form flocs from individual small particles in a suspension by adsorbing on particles and causing destabilization through bridging or charge neutralization. Polymer flocculants are high molecular weight polymers and have hydrogen-bonding groups and/or ionic groups in the molecule.
