PolyDADMAC (Polydiallyldimethylammonium Chloride) – High-Efficiency Cationic Polymer Flocculant for Water Treatment
PolyDADMAC (Polydiallyldimethylammonium Chloride) is a premium high molecular weight cationic polymer flocculant designed for superior performance in drinking water treatment, industrial wastewater treatment, sludge dewatering, paper making, mining water treatment, and oilfield water management. With rapid coagulation, strong adsorption, and excellent turbidity removal capabilities, PolyDADMAC is a highly effective alternative to traditional inorganic coagulants like PAC (Polyaluminum Chloride), PFS (Polysilicate Ferric Sulfate), and aluminum sulfate.
What Is PolyDADMAC?
PolyDADMAC is a linear cationic polyelectrolyte polymer synthesized from DADMAC monomers. It offers:
- High activity and strong solubility
- Low toxicity and eco-friendly characteristics
- Stable flocculation across a wide pH range
- Exceptional ability to remove suspended solids, colloidal particles, COD, SS, and organic impurities
Its strong cationic charge ensures rapid floc formation, making it ideal for applications that demand efficient water clarification and wastewater treatment.
Key Features & Benefits
- Superior coagulation & flocculation: Rapidly neutralizes negative charges to form large, dense flocs
- Higher treatment efficiency than inorganic coagulants like PAC, PFS, or aluminum sulfate
- Wide pH compatibility: Effective between pH 3–7
- Low dosage requirement: Cost-effective operation with minimal chemical usage
- Non-corrosive & low toxicity: Safe for drinking water treatment and industrial applications
- Strong decolorization: Ideal for textile wastewater and dyeing wastewater treatment
- Enhances sludge dewatering performance: Reduces disposal costs and improves sludge cake solid content
