Cationic pam is adopt the unique technology, which enable the molecular weight top 8000 thousand when cation density is 25%.
Add a little (1-100ppm) cation polyacrylamide, it can adsorb large amount of anion particles in sludge and sewage, make the suspending granules concentrate, flocculate and precipitate. The treatment affectivity is much higher than that of anion polyacrylamide, non-ion polyacrylamide.
