Water Treatment Magnafloc Cationic Polyacrylamide PAM White Granule Powder

Ionization degree:
The cationicity is the charge density of the CPAM molecular chain. Cationic degree is one of the determinants of flocculation effect. If the ion is too low, the flocs are small or have no effect. If the ion is too high, the sludge flocs will be repelled due to excessive charge. Therefore, for the sludge to be dewatered, flocculants of different ionicity can be screened through small experiments to select the best and suitable polyacrylamide, which can achieve good flocculant effects, and minimize the amount of chemical added. cost. The key point of ion selection:
(1) The size of the flocs: too small flocs will affect the speed of drainage, too large flocs will bind more water and reduce the degree of mud biscuit. The size of the flocs can be adjusted by selecting the molecular weight of polyacrylamide.
(2) Floc strength (moisture content): The floc should remain stable and not broken under shearing action. Increasing the molecular weight of polyacrylamide or choosing a suitable molecular structure can help improve the stability of the flocculation.
