Quick CPAM Selection Guide
Use this table to shortlist a starting CPAM direction before lab testing and final grade confirmation.
| Application | Starting Grade | Selection Focus |
|---|---|---|
| Municipal sludge dewatering | Medium to high charge density CPAM | Start from sludge type, dewatering equipment, and cake dryness target before final sample testing. |
| Industrial sludge with oil or high organics | High charge density CPAM | Check floc strength, filtrate clarity, and polymer consumption at the same time. |
| Paper retention and drainage | Low to medium charge density CPAM | Balance fines retention, drainage speed, and sheet quality instead of chasing one metric only. |
| Industrial wastewater clarification | Medium charge density CPAM | Confirm upstream coagulant program, pH, and solids profile before scale-up. |

Frequently Asked Questions
What is cationic polyacrylamide (CPAM) used for?
Cationic polyacrylamide is primarily used for sludge dewatering (municipal and industrial sludge on belt presses, centrifuges, and filter presses), paper making (retention and drainage aid), and oily wastewater treatment. The positive charge neutralizes negatively charged sludge particles, enabling rapid flocculation.
What are the MOQ, lead time, and packaging for CPAM export orders?
The standard trial-order MOQ is 500 kg. Common-grade lead time is usually 7-10 days after order confirmation. Standard export packaging is 25 kg kraft paper bags with plastic liner or 25 kg PE bags, with OEM labels supported for suitable orders.
How do I choose the right charge density for sludge dewatering?
Charge density selection depends on sludge type: municipal sewage sludge typically needs 30-50% CD, oily industrial sludge 50-70% CD, and paper mill sludge 20-40% CD. Higher organic content generally requires higher charge density. We provide free jar testing with your sludge sample to determine the optimal grade.
What is the price of cationic polyacrylamide per ton?
CPAM pricing depends on charge density, molecular weight, application target, order quantity, and document requirements. For buying decisions, ask for the recommended grade, sample-test plan, packing option, lead time, and batch document list together instead of comparing by price alone.
What payment methods and packaging are available for CPAM export orders?
The confirmed public payment methods are T/T and L/C. Standard export packaging is 25 kg kraft paper bags with plastic liner or 25 kg PE bags, and OEM labels are supported after grade, bag type, and artwork scope are confirmed.
