Product Positioning

PolyDADMAC, also known as PDADMAC or PDMDAAC, is a cationic polymer widely used in water treatment. DA404 is specially developed for extreme solid rich environments such as mining wastewater, mineral processing tailings, sand washing water, and slurry separation systems.

It is engineered for treatment conditions where suspended solids are high, settling is difficult, and conventional clarification programs may not deliver sufficient separation efficiency.

Why DA404 Performs in Mining Systems

Mining and slurry systems present special treatment challenges, including high density suspended solids, abrasive particles, and poor natural settling behavior. DA404 is designed to improve separation performance under these difficult industrial conditions.

Strong Particle Bridging

DA404 connects heavy particles effectively and helps form larger flocs quickly, improving solid aggregation in high solids systems.

High Settling Efficiency

It accelerates sedimentation in clarifiers and thickeners, helping improve overflow water clarity and separation speed.

Resistance to Harsh Conditions

DA404 performs well in high shear environments and helps maintain floc integrity under turbulence and demanding plant conditions.

Performance in Slurry Systems

Tailings Treatment

DA404 supports faster separation of solids and water in tailings systems, helping reduce pond load and improve water management efficiency.

Sand Washing Plants

It helps improve water recycling performance and reduce suspended solids in recovered process water from sand and aggregate washing operations.

Thickening Systems

DA404 can improve sludge concentration and underflow density, making it suitable for thickening applications in mining and heavy industry.

Key Benefits

Technical Specifications

Ideal Application Scenarios

Mining Wastewater

DA404 is highly recommended for coal washing plants, metal mining operations, and other mineral processing systems where suspended solids are high and clarification is difficult.

Slurry Separation

It is suitable for sand and gravel processing, construction wastewater, and slurry separation systems requiring rapid settling and improved water recovery.

High Solids Industrial Wastewater

DA404 also performs well in mineral processing wastewater and heavy industry effluent streams with high suspended solids and difficult settling behavior.

NSF Certification Advantage

Bluwat PolyDADMAC products are NSF certified for drinking water treatment chemicals, supporting compliance with international standards in regulated water treatment systems.

Although DA404 is mainly used in industrial systems, it can also support water reuse systems and integrated treatment plants that require certified chemical solutions.

Process Application

DA404 is suitable for rapid solid liquid separation programs in mining and industrial slurry systems where strong floc formation is required before sedimentation or thickening.

Results

• Faster settling
• Higher solid capture
• Improved water reuse

Dosage Strategy

• Dilute to 0.5 percent to 5 percent solution before use
• Adjust dosage according to solids concentration and settling target
• Jar testing is recommended for process optimization
• Avoid excessive mixing to protect formed flocs

Packaging and Storage

Store in cool and dry conditions away from sunlight to maintain stable product quality and treatment performance.
