Cationic Polyacrylamide (CPAM) – Advanced Sludge Dewatering & Wastewater Clarification Polymer
Cationic Polyacrylamide (CPAM) produced by Vanzon Water is a high-performance water-soluble polymer with a positive charge density. Engineered for superior interaction with negatively charged particles, CPAM excels in sludge dewatering,
wastewater clarification, and organic matter removal. Its tailored molecular structure ensures rapid flocculation, reduced
sludge volume, and compliance with stringent environmental standards.
Key Functions & Mechanisms for cationic polyacrylamide
Charge Neutralization
▲Binds to negatively charged colloids (e.g., organic sludge, proteins, cellulose fibers) via electrostatic attraction.
Bridging Flocculation
▲Long polymer chains bridge particles into dense, fast-settling flocs.
Sludge Dewatering
▲Releases bound water from biological/organic sludge, reducing moisture content by 25-50%.
Filtration Enhancement
Improves dewatering speed on belt presses/centrifuges/ screw /plate and frame press; cuts energy consumption.

Instructions of cationic polyacrylamide:
1.Before using,dissolve polyacrylamide with tap water at a ratio of 0.1%-0.5% and stir until fully dissolved.
2. Do not use iron materials to stir or hold PAM, because the reaction performance of PAM will decrease when it encounters iron.
3. The dosage needs to be calculated through laboratory pilot tests, with the aim of achieving the aggregation of flocs and presenting the phenomenon of sludge-water separation.
4.It is better to use up the prepared PAM solution within 24 hours.
5.Products should be stored in unopened package in a dry atmosphere at temperature no higher than 35℃.
