Cationic Polymeric Flocculant Beads Polydadmac Pdadmac P-Dadmac Granular Bead

Product Specification

High-Performance Granular Bead-Type Polymer for Clarification, Thickening, and Sludge Solids Improvement

Polydadmac bead-type polymers—also known as Pdadmac, P-Dadmac, or Q-Pdmdaac—are high-efficiency cationic polymeric flocculants engineered for modern water purification and sludge dewatering systems. Their granular form, high active content, and strong quaternary ammonium charge make them ideal for applications that require fast floc formation, enhanced solid–liquid separation, and improved sludge dryness.

Whether in municipal water treatment, industrial wastewater clarification, or sludge thickening units, these bead-type polymers deliver consistent, reliable performance with lower chemical consumption and reduced sludge handling costs.

1. Overview of Cationic Polydadmac Bead-Type Flocculant

Polydadmac beads are solid, free-flowing granules of poly(diallyldimethylammonium chloride) designed for enhanced flocculation efficiency. Their strong positive charge rapidly neutralizes negatively charged suspended solids, organic matter, and colloids.

Core Characteristics

• White granular bead-type polymer

• High active content (≈90–92%)

• Strong, permanent quaternary ammonium cationic charge

• Uniform hydration and easy dissolution

• Stable under broad pH and operational conditions

• Excellent performance in clarification and dewatering

The bead-type format improves handling safety, minimizes dust, and ensures long storage stability.

2. Why This Polymer is Powerful for Water Purification

✔ Rapid Clarification

Polydadmac beads act quickly to collapse colloids and fine particles, producing clear supernatant water in both primary and tertiary treatment stages.

✔ High Efficiency at Low Dosages

The high active content allows treatment plants to achieve strong results with minimal polymer usage—reducing operational cost.

✔ Excellent Compatibility with Multi-Stage Systems

Performs well alongside PAC, alum, ferric salts, and other coagulants in integrated treatment lines.

✔ Effective Across Various Water Types

Applicable to:

• Surface water

• River and lake water

• Groundwater with high turbidity

• Industrial process water

Its versatility makes it suitable for water purification plants of any scale.

3. Strong Performance in Sludge Dewatering & Thickening

Sludge management is a major cost in wastewater treatment. Polydadmac bead-type polymers significantly improve sludge processing efficiency through:

✔ Formation of Dense, Compact Flocs

Produces stronger flocs that separate water more effectively.

✔ Improved Solids Capture Rate

Enhances filtration, centrifugation, belt press, and screw press performance.

✔ Reduced Sludge Volume

Lower water content in sludge results in reduced landfill or transport cost.

✔ Better Cake Dryness

Improves final sludge quality and reduces disposal difficulty.

✔ Stabilizes Dewatering Under Variable Conditions

Consistent performance even when influent characteristics change.

These advantages make Q-Pdmdaac and Polydadmac beads preferred choices in sludge thickening and mechanical dewatering systems.
