drinking water treatment by stepwise flocculation using polysilicate aluminum magnesium and cationic polyacrylamide

Drinking water treatment by stepwise flocculation using polysilicate aluminum magnesium and cationic polyacrylamide

In view of the aforementioned aspects, the prepared cationic polyacrylamide (cPAM) and polysilicate aluminum magnesium (PSAM) were used to stepwise flocculation drinking water. More importantly, in the flocculation procedure, the positive cPAM was first added into the simulated water sample to adsorb the negative impurities through charge neutralization.

Understanding the synergistic mechanism of PAM-FeCl3 for improved sludge dewaterability

Among various chemical conditioners, cationic polyacrylamide (CPAM) is widely used in sludge treatment plants due to its advantages of fast treatment rate and wide application range. However, the disadvantages of CPAM for sludge dewatering are its high filter cake moisture content (FCMC) and slow filtration rate.
