Diallyl Dimethyl Ammonium Chloride Polymer Polydadmac Pdadmac P-Dadmac Q-Pdmdaac Beads for Coagulation

High-Activity Bead-Type Cationic Polymer for Advanced Clarification & Solid–Liquid Separation

Diallyl Dimethyl Ammonium Chloride Polymer—commonly known as Polydadmac, Pdadmac, P-Dadmac, or Q-Pdmdaac—is a high-efficiency cationic polymer widely used in water treatment systems that require strong coagulation and rapid particle destabilization. In bead-type form, this polymer offers exceptional purity, stability, and performance, making it an ideal choice for drinking water, municipal facilities, industrial wastewater, and process-water clarification.

The bead-format polymer delivers consistent dissolution, high active content, and reliable floc formation, enabling operators to achieve clear, stable water quality even under challenging treatment conditions.

1. Overview of Diallyl Dimethyl Ammonium Chloride Polymer Beads

This polymer is a quaternary ammonium cationic flocculant designed to neutralize negatively charged particles rapidly. Its bead-type structure ensures easy handling and long shelf life while delivering higher efficiency compared with liquid coagulants.

Key Features

• Solid bead / granular appearance

• High active content (typically around 90–92%)

• Strong, permanent cationic charge

• Highly effective within broad pH ranges

• Fast coagulation response for improved clarity

• Uniform dissolution with minimal residue

These attributes make it suitable for both simple and highly contaminated water matrices.

2. Coagulation Advantages of Polydadmac & Its Variants

Superior Charge Neutralization

The quaternary ammonium groups provide strong, immediate charge neutralization, leading to the rapid breakdown of colloidal stability.

Enhanced Floc Structure

Produces compact, dense flocs with excellent settling or flotation characteristics, improving sludge separation and downstream filtration.

High Activity = Low Dosage

Due to the concentrated active content, only small amounts are needed to achieve strong coagulation, reducing chemical usage and operational costs.

Stable Performance Across Water Qualities

Effective on both low-turbidity and highly polluted water, including waters containing dyes, organics, emulsions, and suspended solids.

Works as a Primary or Secondary Coagulant

Can be used independently or in conjunction with PAC, alum, or other inorganic coagulants to enhance treatment efficiency.

Reduced Sludge Generation

Better coagulation kinetics lead to less sludge volume and easier dewatering—beneficial for facilities working to lower disposal costs.
