Influence of Different Factors on Flocculation Effect of Polyacrylamide on Water from Yellow River

Abstrcat Using the polyacrylamide as the flocculation agent, the factors influencing the flocculation effect on the water from the Yellow River are discussed. The results show that the best flocculation effect in 100 mL low turbidity water is the treatment of adding 0.1% PAM 0.09 mL, 25 ℃,180 r/min for 2 minutes, and depositing for more than 6 minutes.
