🔍Product Overview
PolyDADMAC, also known as PDADMAC or Poly(dimethyl diallylammonium chloride), is a liquid cationic polymer widely used as a primary coagulant and coagulant aid in drinking water treatment, wastewater treatment, sludge dewatering, industrial clarification, paper-making, mining, and oil industry applications.
Bluwat PolyDADMAC 40% Liquid is designed for water treatment plants that need efficient charge neutralization and stable clarification performance. In municipal drinking water treatment, raw water may contain clay, silt, algae, natural organic matter, colloids, and fine suspended particles. These particles are usually negatively charged and difficult to remove by natural settling alone.
Bluwat PolyDADMAC 40% Liquid Primary Coagulant provides strong cationic charge to neutralize these particles and promote the formation of larger flocs. This helps improve turbidity removal, sedimentation efficiency, filter performance, and overall water treatment stability.
For drinking water projects, the applicable NSF certification scope, certified product grade, and maximum use level should be confirmed according to local potable water regulations and the latest certificate documents.
💧Application in Municipal Drinking Water Plants
Municipal water treatment plants require reliable coagulants to treat variable raw water quality and meet potable water standards. PolyDADMAC 40% Liquid can be used as a primary coagulant or in combination with inorganic coagulants such as PAC, alum, or ferric salts.
Typical applications include:

🏷️Available 40% PolyDADMAC Liquid Grades
DA 401 (Low MW)
Viscosity: <500 cps. Ideal for fast dispersion and low-viscosity dosing systems.
DA 402/403 (Medium MW)
Viscosity: 500-3000 cps. Balanced coagulation performance for general raw water.
DA 404/405 (High MW)
Viscosity: 3000-8000 cps. For higher turbidity and stronger floc requirements.
DA 406/407/408 (Very High MW)
Viscosity: 8000 to >15000 cps. For algae-containing water and challenging clarification.
💡Application Method & Selection
PolyDADMAC 40% Liquid should be selected based on raw water turbidity, organic matter, temperature, and pH. When used alone, it is normally diluted to 0.5–5% concentration before dosing.
For low to medium turbidity, DA 401 to DA 403 are recommended. For high turbidity or algae, DA 404 to DA 408 provide stronger floc formation. Optimum dosage must be confirmed by jar testing.
📦Packaging and Storage
Available in 25L plastic drums, 200L plastic drums, and 1000L IBC drums. Store in a cool, dry place away from direct sunlight and heat.
