Product Overview

PolyDADMAC, also known as PDADMAC or PDMDAAC, is a high charge density cationic polymer widely used in coagulation and flocculation processes. DA203 is a medium high viscosity grade specifically developed for water systems where standard coagulants alone are not sufficient.

It bridges the gap between general purpose polymer grades such as DA201 and DA202 and heavier duty grades such as DA204 and above, making it a practical choice for treatment systems that need stronger floc structure without moving to very high viscosity products.

Performance Focus

DA203 is optimized for enhanced flocculation performance in more demanding treatment systems. It is especially suitable for high turbidity water, industrial wastewater with unstable quality, and systems containing fine suspended solids that are difficult to separate efficiently.

How DA203 Solves Common Problems

Problem 1 Flocs Too Small

DA203 helps build larger and stronger flocs, improving solid liquid separation in systems where flocs formed by standard treatment are too fine or too weak.

Problem 2 Slow Sedimentation

By improving aggregation and floc structure, DA203 supports faster settling and cleaner supernatant in clarification and sedimentation processes.

Problem 3 Variable Water Quality

DA203 provides more stable treatment performance when raw water conditions fluctuate, helping operators maintain consistent clarification results.

Problem 4 Poor PAC Efficiency

DA203 improves coagulation synergy with PAC, making the overall treatment sequence more effective in difficult water conditions.

Key Advantages

Technical Specifications

Typical Application Scenarios

1 High Turbidity Surface Water

DA203 is suitable for river water during rainy seasons and reservoir water containing higher levels of suspended solids, where improved floc structure is needed for stable clarification.

2 Industrial Wastewater with Fluctuation

It performs well in textile dyeing wastewater and chemical wastewater systems where water quality changes frequently and process consistency is harder to maintain.

3 Pretreatment Before Filtration

DA203 can improve pretreatment performance before filtration by reducing suspended solids more effectively and lowering filter load.

4 Systems Requiring Stronger Floc Structure

It is suitable for clarifiers and sedimentation tanks where stronger and more stable flocs are required to support efficient separation.
