POLYDADMAC LIQUID
Poly(diallyldimethylammonium chloride) · PolyDADMAC (liquid grade) · CAS 26062-79-3
High–molecular-weight cationic polyelectrolyte for charge neutralization, bridging, and solids separation in municipal and industrial water systems.
Product overview
POLYDADMAC LIQUID is a linear, water-soluble cationic polymer used as a primary coagulant or coagulant aid. Positively charged groups neutralize negatively charged colloids and organic matter for faster aggregation and clearer filtrate.
Consistent performance from raw-water intake to sludge handling—one chemistry, many unit operations.
Grades differ in viscosity, solids, and molecular weight; match to influent chemistry, mixing, and downstream limits.
In continuous treatment lines, dosing strategy and injection point are as important as product grade. Jar tests, streaming-current trends, and sludge dewatering feedback should be combined to define an operating window that balances clarity, chemical cost, and sludge transportability.
Why operators choose it
Performance
- Strong charge neutralization across a practical pH window
- Effective on color, turbidity, and many NOM fractions
- Works with inorganic coagulants when dual treatment is used
- Often lowers downstream solids loading in clarification trains
- Supports more stable filtration run times under variable feed quality
Operations
- Liquid grades simplify metering and dispersion
- Proven handling in large-scale plants
- Helps stabilize clarifier and filter performance
- Compatible with automated dosing and feedback control loops
- Can reduce operator interventions during hydraulic fluctuations
Control points
- Prepare dilution water quality and ageing time according to supplier guidance
- Verify flash-mix energy and contact time before floc growth zone
- Track residual cationic demand where membrane or reuse systems are downstream
Typical applications
- Drinking water and municipal wastewater clarification
- Industrial effluent (food, textile, chemical processing)
- Sludge conditioning and mechanical dewatering support
- Papermaking retention and drainage (grade-dependent)
- Process water recycle loops; specialty cationic formulations
- Mining and mineral washing circuits with high suspended solids
- Surface water pretreatment ahead of UF/RO systems
- Cooling-water side stream polishing in industrial utilities
Application envelope depends on raw-water alkalinity, organics profile, salinity, and target discharge standards. Pilot runs are recommended for duty-critical systems.
TDS-aligned use cases
- Cationic flocculant in wastewater, mining, and mineral processing
- Formaldehyde-free fixing agent in textile processing
- Anionic trash catcher and AKD sizing promoter in papermaking
- Clay stabilizer and oil-water separation aid in oilfield operations
