Effect of Flocculation of Cationic Polyacrylamide on the Migration Rate of Suspended Particles
The effects of concentration of cationic polyacrylamide and pH-value on the migration rate of suspended particles have been measured by a Turbiscan Lab dispersion stability analyzer. The results showed that the migration rate of the suspended particles increases with the increase of concentration of cationic polyacrylamide between 40 and 70mg/L and decreases with the increase of its concentration between 70 and 90mg/L. The migration rate of suspended particles decreases with increasing pH-value or settling time.
