Dosing Guidelines

Prepare 0.1-0.5% stock solution. Typical dosing: 0.5-5 mg/L active polymer. Allow 30-60 min dissolution time.

How It Works

Cationic polyacrylamide adsorbs onto negatively charged particles, bridging them together into large, settleable flocs for efficient sludge dewatering.

Usage Tips

Available in 25 kg bags. Dissolve slowly with gentle agitation. Avoid over-dosing which can restabilize particles.

Frequently Asked Questions

What is the difference between cationic, anionic, and nonionic PAM?▼

Cationic PAM works best with negatively charged particles (most wastewater), anionic PAM suits positively charged particles, and nonionic PAM is used for specific applications. Our PAM is cationic, optimized for municipal and industrial sludge dewatering.

How long does prepared PAM solution remain effective?▼

Prepare PAM solutions fresh daily for best results. Diluted solutions begin degrading within 24-48 hours due to polymer chain breakage. Always prepare only the amount needed for immediate use.

What mixing speed should be used when preparing PAM solutions?▼

Use gentle mixing (50-150 RPM) to avoid shearing polymer chains. High-speed mixing permanently damages the polymer and reduces effectiveness. Allow 30-60 minutes dissolution time with slow agitation.

Can PAM be overdosed, and what happens if it is?▼

Yes, overdosing PAM can restabilize particles and worsen performance. Signs include poor floc formation, increased turbidity, and higher polymer consumption. Always start with low doses and gradually increase while monitoring performance.

What factors affect PAM performance in dewatering applications?▼

Key factors include sludge characteristics (organic content, particle size), mixing intensity, contact time, and equipment type. Conduct small-scale tests to optimize polymer type, dose, and application method for your specific sludge.
