  • What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.
  • What is the difference between cationic starch and cation polyacrylamide?
  • The relative efficiency of the cationic starch and cationic polyacrylamide (CPAM) can be attributed to the difference in their charge density (CD). The CD of the C. Starch used in this study is about 0.9 mEq/g and the CD of the CPAM is 2.85 mEq/g. In other words, the CD of the C. Starch is only 31% of CPAM’s CD.
  • Do cationic and anionic polyacrylamide settling rates increase with charge density?
  • The maximum settling rates of flocs produced by cationic and anionic polyacrylamides decrease with charge density and increase with molecular weight.
  • Why do cationic polyacrylamides flocculate negatively charged particles?
  • The flocculation of negatively charged fine particles by high molecular weight cationic polyacrylamide occurs by the adsorption of the polyacrylamide chains on to the particle surface. Thus charge neutralization becomes a major mechanism, where the cationic polyacrylamides will locally reverse the particle surface charge.
