Cationic Polyacrylamide CPAM
Cationic polyacrylamide (CPAM) is a linear polymer compound. As it has a variety of active groups, it can form hydrogen bonds with many substances through affinity and adsorption. Mainly flocculates negatively charged colloids, with functions such as turbidity removal, decolorization, adsorption, and adhesion. It is suitable for the wastewater treatment with organic colloid content in dyeing, papermaking, food, construction, metallurgy, mineral processing, coal powder, oil fields, aquatic product processing and fermentation and other industries, especially suitable for dehydration treatment of urban sewage, urban sludge, papermaking sludge and other industrial sludge.

Cationic Polyacrylamide Selection and Procurement Notes
Cationic polyacrylamide is mainly selected for organic sludge dewatering, municipal sewage sludge, paper sludge, food processing wastewater, alcohol and fermentation wastewater, and other systems where negatively charged colloids need to be neutralized and bridged. The key selection factors are cationic charge degree, molecular weight, dissolution time, sludge concentration, pH, and the dewatering equipment type.
- Typical use: belt filter press, screw press, centrifuge, plate-and-frame filter press, and sludge thickening.
- Testing method: prepare a 0.1%-0.3% solution, mature completely, then compare floc size, filtrate clarity, cake moisture, and dosage.
- Procurement support: sample, COA, MSDS, packaging, and technical grade recommendation are available for project buyers.
FAQ
How do I choose the charge degree of CPAM?
Higher organic sludge content usually needs a higher cationic charge, but the best grade should be confirmed by jar test and dewatering equipment trial.
Why does CPAM sometimes fail in sludge dewatering?
Common reasons include incomplete dissolution, wrong charge degree, overdosing, fast mixing damage, sludge quality change, or using a solution that has aged too long.
Can Xinqi provide samples before bulk order?
Yes. Buyers can request samples and share wastewater or sludge information so Xinqi can recommend a suitable cationic polyacrylamide grade.
