  • Liquid Flocculation of Emulsions: Practical Guide

    Comprehensive Understanding of Dispersants PAM in Paper Mills Dispersants PAM (Polyacrylamide) are anionic or nonionic water-soluble polymers designed to optimize pulp dispersion, improve fiber suspension stability, and minimize aggregation during paper production. Their molecular structure contains carboxyl and amide functional groups that interact with pulp fibers, pigments, and fillers, crea...

  • Polyacrylamide: Precipitation & Bridging Chemical

    Mechanisms: How polyacrylamide precipitates and bridges organic colloidal particles Polyacrylamide (PAM) causes removal of organic colloids primarily by two complementary physical–chemical mechanisms: charge neutralization (precipitation) and bridging flocculation. In charge neutralization, cationic PAM (or partially hydrolyzed PAM in the presence of multivalent cations) reduces the electrostatic ...
