High Cationic Charge Density

Provides rapid charge neutralization and effective destabilization of negatively charged suspended solids and colloids.

Ready-to-Use Liquid Form

Easy to meter, dilute and introduce into an existing treatment process without lengthy powder-polymer dissolution.

Complete Grade Range

Seventeen grades are available, covering three solid-content levels and a broad molecular-weight range.

Flexible Coagulation Programs

Can be used alone or together with PAC, alum, ferric salts or PAM, depending on the raw water and treatment objective.

Potential Reduction in Inorganic Coagulant Consumption

In an optimized system, PolyDADMAC may reduce the required dosage of alum, ferric salts or PAC and may help control total sludge production.

Improved Solid–Liquid Separation

Supports faster clarification, better floc formation, improved sludge thickening and more efficient dewatering.

Broad pH Applicability

The supplied product profile identifies a broad application range of approximately pH 0.5–14. Actual performance and optimum dosage should always be confirmed using representative water samples.

NSF-Certified Drinking-Water Options

Suitable certified grades are available for potable-water treatment, subject to the current certificate, maximum use level and local regulations.

Choose the 20% Series When:

• Lower liquid viscosity is preferred
• The dosing pump has limited viscosity capacity
• Easier dispersion and accurate low-rate metering are important
• The process primarily requires charge neutralization
• The plant prefers a lower-concentration working product

Choose the 40% Series When:

• A balance between active content and pumpability is required
• The customer needs a broad choice of molecular-weight grades
• The product will be used in municipal or industrial clarification
• Both coagulation and floc-building effects need to be evaluated
• Transportation efficiency is important

Choose the 50% Series When:

• High active content is preferred for freight efficiency
• The dosing system can handle a more viscous liquid
• High or very-high-molecular-weight grades are required
• The application involves demanding solid–liquid separation or sludge treatment
• On-site storage volume needs to be reduced

Important Selection Factors

Before recommending a commercial grade, Bluwat normally considers:

• Type and source of water
• Turbidity and suspended solids
• Colour and organic content
• Wastewater pH
• Existing PAC, alum or ferric-salt dosage
• Required settling or flotation speed
• Sludge volume and dewatering performance
• Dosing-pump capacity
• Operating and storage temperature
• Required treated-water quality

Drinking Water Treatment

Suitable NSF-certified grades can be used as organic coagulants or coagulation aids for turbidity reduction, colloid destabilization and clarification in municipal and industrial drinking-water plants.

For potable-water applications, the exact certified grade and maximum use level must be confirmed before use.

Municipal Wastewater Treatment

PolyDADMAC supports primary clarification, suspended-solids removal, sludge thickening and optimization of existing coagulation processes.

Industrial Wastewater Clarification

Suitable for treating suspended solids, colloids and negatively charged contaminants in a wide range of industrial effluents.

Mining and Mineral Processing

Used to improve solid–liquid separation in:

• Coal washing
• Gold processing
• Diamond processing
• Mineral slurry clarification
• Process-water recycling
• Tailings-water clarification

The final grade must be selected according to mineral type, slurry concentration, water chemistry and separation equipment.

Pulp and Paper Industry

PolyDADMAC can function as:

• Charge neutralizer
• Retention aid
• Drainage enhancer
• Anionic trash catcher
• Process-water clarification aid

It can help stabilize wet-end chemistry and improve the efficiency of other retention and drainage chemicals.

Textile Industry

Used for wastewater clarification, colour-treatment programs and process-water recycling. For strongly coloured wastewater, PolyDADMAC may be combined with a dedicated decolorizing agent, PAC and PAM.

Oil and Gas Industry

Applicable to oily wastewater and produced-water treatment, where it can support destabilization of dispersed contaminants and improve downstream separation.

Compatibility should be tested against salinity, oil content, temperature and the existing demulsification process.

Sludge Thickening and Dewatering

PolyDADMAC can improve charge neutralization before sludge thickening or mechanical dewatering. In some systems, it can be combined with cationic or anionic PAM to produce stronger and more drainable flocs.

PolyDADMAC Used Alone

Raw water → PolyDADMAC dosing → Rapid mixing → Floc formation → Sedimentation or flotation → Filtration

Suitable when charge neutralization and primary coagulation are sufficient.

PolyDADMAC Combined with PAC

Raw water → PolyDADMAC and/or PAC → Rapid mixing → Flocculation → Sedimentation or DAF → Filtration

The best dosing sequence should be established by jar testing because it may vary with the contaminant and existing plant design.

PolyDADMAC Combined with PAM

Raw water → PolyDADMAC destabilization → PAM flocculation → Sedimentation, DAF or dewatering

PolyDADMAC first neutralizes the particle charge, while PAM helps build larger and stronger flocs.

Sludge Dewatering Program

Sludge conditioning → PolyDADMAC or combined polymer program → Gentle mixing → Belt press, centrifuge or filter press

Evaluate cake solids, filtrate clarity, polymer consumption and equipment throughput during testing.
