Best Anionic PAM for Water Treatment

In water treatment, coal washing, and sand washing, choosing the right anionic polyacrylamide (PAM) is very important. The hydrolysis degree and molecular weight of PAM affect both the flocculation effect and the cost.

Choosing the Right Hydrolysis Degree

• Medium Hydrolysis (23%–27%) Best for flocculation and settling. Often used with coagulants like PAC or PFS. Common in industrial wastewater pre-treatment.
• High Hydrolysis (28%–35%) Good for high-concentration sludge and inorganic wastewater. It makes flocculation stronger.
• Low Hydrolysis (5%–15%) Mostly used for mining or low-concentration wastewater.

Choosing the Right Molecular Weight

• 12–16 million Good for industrial wastewater. It’s a good balance between performance and cost.
• 18–25 million Used in coal washing and sand washing. It increases viscosity, less product is needed, which saves money.
• Above 25 million Higher cost. Usually not needed for most projects.

Summary

When choosing PAM, think about:

• The type of water
• Your treatment goal
• And your budget

This helps you get better flocculation results and save money at the same time.
