  • Are cationic polyacrylamides better than anionic polyamides?
  • They suggested that cationic polyacrylamides (PAM) produced floc aggregates with larger size, greater shear-resistant ability and higher regrowth capacity than anionic one, arising from the contribution of charge neutralization and bridging effects , , .
  • Do polyanions interact with cationic proteins?
  • Thus, the interaction with proteins depends on both, the protein and polymer characteristics, showing stronger interactions with cationic proteins. However, polyanions, in particular sulfated and carboxylated polysaccharides, are known for their good modulation of blood coagulation. (62) Figure 4.
  • Does lysozyme interact with cationic proteins?
  • Lysozyme interacts as well with P (Gly-OH-AAm), leading to, however, smaller aggregates ( d ≈ 150 nm). Thus, the interaction with proteins depends on both, the protein and polymer characteristics, showing stronger interactions with cationic proteins.
  • Does polymer-enhanced floc cohesion affect particle aggregation during ballasted flocculation?
  • 4. Diverse predominant floc-growth mechanism (such as charge neutralization, polymer bridging, and/or electrostatic patch) seemed to occur for each combination of coagulant dosage and PAM type, thus determining the interaction between polymer-enhanced floc cohesion and particle aggregation during ballasted flocculation.
