Pdadmac Polydadmac Bead-Type Cationic Polymeric Flocculant for Water Treatment Poly (Diallyldimethylammonium Chloride)

High-Purity Poly (Diallyldimethylammonium Chloride) for Clarification, Coagulation & Sludge Reduction

PolyDADMAC, or Poly (Diallyldimethylammonium Chloride), is a highly efficient cationic polymeric flocculant widely used in both drinking water and industrial wastewater treatment. With the growing need for rapid clarification, lower sludge production, and more economical treatment strategies, bead-type PolyDADMAC has become a preferred material for modern water treatment facilities and industrial users.

Compared with liquid or traditional powder forms, bead-type PolyDADMAC offers higher stability, greater active content, easier transportation, and excellent performance in a wide range of applications.

1. What Is Bead-Type PolyDADMAC?

Bead-type PolyDADMAC is a solid, high-purity cationic polymer with a typical active content of ≥90%. Its compact bead structure improves handling, dissolution rate, and storage stability, making it highly suitable for bulk treatment systems.

Key characteristics include:

• High charge density for fast particle destabilization

• Stable in a wide pH range (0.5–14)

• Available in low- and high-viscosity grades

• Cost-effective due to high solid content

• Uniform bead appearance for consistent dissolution

These properties make Polydadmac beads suitable for municipal water works, industrial plants, and specialized treatment processes across multiple industries.

2. Performance Advantages of Polydadmac Beads

High Solid Content

With ≥90% active ingredient, bead-type PolyDADMAC significantly reduces transportation cost, storage space, and total usage cost.

Strong Cationic Charge

Delivers rapid coagulation and flocculation, even at low dosages, helping remove suspended solids, colloids, dyes, and organic impurities.

Can Replace Alum & Ferric Salts

When used as a primary coagulant, Polydadmac can reduce or eliminate the need for conventional inorganic coagulants, resulting in lower sludge and improved system corrosion control.

Works Independently or Together with PAC

Polydadmac beads work effectively on their own and also show strong synergy with Poly Aluminium Chloride (PAC) in drinking water treatment and surface water clarification.

Wide pH Applicability

Effective in extremely acidic, neutral, or alkaline water systems, making the polymer suitable for complex industrial effluent.

Its high efficiency helps minimize sludge production during clarification and dewatering processes.
