Choosing the Right Polyacrylamide Flocculant: A Comprehensive Guide

Matching the PAM type to the water¡¯s characteristics ensures optimal flocculation performance. PAM Dosage: The optimal PAM dosage depends on the water quality, desired treatment efficiency, and flocculant¡¯s concentration. Conducting jar tests or seeking guidance from water treatment experts can help determine the appropriate dosage.

Water Soluble Polymer Flocculants: Synthesis, Characterization, and

Flocculants with less than 1% charged functional groups are considered as nonionic flocculants. 34 Nonionic flocculants normally have high molecular weights, which helps them flocculate suspended particles through the bridging mechanism. 35 Polyacrylamide is the most important water soluble nonionic flocculant because its monomer, acrylamide, is highly water soluble, cost-effective, and very

A comparison study between bioflocculants and PAM for dewatering of

This high viscosity limited PAM distribution as a flocculant through the suspensions. Results highlighted that PAM had the highest flocculation activity in low dosages (0.05 and 0.1 wt%) while in dosages above 0.25 wt%, cationic biopolymers; protamine, and lysozyme for kaolinite and anionic pectin for serpentine showed a higher performance than the other polymers.

IOP Conference Series: Earth and Environmental Science PAPER OPEN

Action Mechanism of Pam PAM chemical are divided into cationic chemical and anionic chemical. Cationic chemical are mainly used in sewage treatment plant for sludge dewatering, and anionic chemical are used for flocculation or coagulation aid. The action mechanism of cationic chemical is discussed as follow.

Understanding the synergistic mechanism of PAM-FeCl

Organic-inorganic hybrid flocculants are widely used as high-performance materials in water treatment (Lee et al., 2011; Razani et al., 2019). Nevertheless, only a few researchers have studied the application of hybrid flocculant PAM-FeCl 3 in sludge pretreatment, and the mechanism for sludge conditioning was virtually unexplored.
