Polydadmac Beads Pdadmac P-Dadmac Q-Pdmdaac Granular Polymer Da9001h/Da9001L High and Low Viscosity Grades

High- and Low-Viscosity Cationic Grades for Precision Water & Wastewater Treatment

Polydadmac beads—also referred to as Pdadmac, P-Dadmac, or Q-Pdmdaac—are high-efficiency cationic granular polymers engineered for advanced water clarification, coagulation, and sludge conditioning. Offered in DA9001H (high-viscosity) and DA9001L (low-viscosity) grades, these bead-type polymers provide tailored performance for both simple and highly challenging treatment environments.

With a high active content, uniform bead structure, and strong quaternary ammonium charge, Polydadmac bead polymers deliver superior solid–liquid separation results across multiple industrial sectors.

1. Overview of DA9001H & DA9001L Granular Polymers

Polydadmac is a solid, bead-type poly(diallyldimethylammonium chloride) designed for rapid coagulation and floc formation. Both DA9001H and DA9001L share similar chemistry but offer different viscosity and molecular-weight profiles to match various treatment needs.

DA9001L – Low-Viscosity Grade

• Fast dissolving

• Ideal for general clarification

• Suitable for low-to-medium strength wastewater

• Provides stable coagulation with moderate floc size

DA9001H – High-Viscosity Grade

• Higher molecular weight

• Stronger flocculation capability

• Suitable for difficult, high-turbidity or high-COD wastewater

• Builds larger, denser flocs for improved separation

Together, these two grades give operators flexibility to optimize cost, performance, and process stability.

2. Key Functional Advantages of Polydadmac Beads

Strong Cationic Charge for Rapid Coagulation

The quaternary ammonium structure provides a permanent positive charge that quickly destabilizes colloids, dyes, and suspended solids.

High Active Content for Lower Dosage

At around 90–92% solids, these beads require significantly less dosage than liquid coagulants.

Precise Grade Selection (High vs. Low Viscosity)

• DA9001L: Efficiency + economy

• DA9001H: Maximum performance in complex wastewater

Clean & Consistent Dissolution

Bead structure ensures minimal dusting, uniform hydration, and reliable quality.

Reduced Sludge Production

Produces compact flocs that generate lower sludge volumes and improve downstream dewatering.

Performs Well Across Wide pH Ranges

Effective in acidic, neutral, and alkaline wastewater systems.
