POLYDADMAC LIQUID
Cationic coagulantWater & process
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
