Cationic polyacrylamide is used for flocculation

When cationic polyacrylamide dissolves water, sprinkle the product evenly into the stirred water, and heat properly.

Principle of flocculation: cationic polyacrylamide for flocculation, related to the surface properties of the floc, especially the suspension of the potential, viscosity, turbidity, PH value. The electrodynamic potential of particle surface is the cause of particle polymerization. The addition of PAM with opposite surface charge can reduce the galvanic potential and cause coagulation. But the quality and dosage of polyacrylamide must be controlled, because there will inevitably be a small amount of unpolymerized acrylamide monomer in polyacrylamide, with gun neurotoxicity and teratogenic, carcinogenic, mutagenic effects. The high concentration of acrylamide monomer in drinking water is 0.01 mg/L..

Cationic polyacrylamide application: polymer types, specifications, dosage and proportioned concentration. Aluminum sulfate PAM is polyacrylamide. There are three main types of PAM, namely anionic, cationic, and anionic. Depending on the type of ion, the required solution environment is different, and anions work better in basic conditions.
