Blufloc EWC 8040 and EWC 8060 Water-Based Cationic PAM Emulsion

Product Introduction

Water-based emulsion can be attractive for sites that prefer its carrier profile or have equipment designed for water-based polymers. However, water-based does not remove the need for correct activation, controlled dilution, and performance testing.

The two EWC grades allow the site to compare high and very-high cationic charge without switching product format.

Blufloc EWC 8040 and EWC 8060 are water-based cationic PAM emulsions with high molecular weight and high or very-high charge. They are intended for rapid preparation and sludge conditioning in compatible automatic dosing systems.

Application Challenges

• Choosing carrier type without checking dosing skid compatibility
• Insufficient dilution or mixing during rapid make-down
• Using charge level as the only selection criterion
• Allowing prepared solution quality to vary between shifts

How the PAM Emulsion Works

EWC polymers use cationic groups for charge neutralization and long chains for bridging. The water-based formulation supports liquid handling, while final flocculation performance still depends on sludge demand, molecular configuration, and preparation conditions.

Recommended Blufloc Grades

Product Advantages

• Water-based carrier option
• High and very-high cationic charge choices
• High molecular weight for effective bridging
• Suitable for compatible continuous make-down systems
• Factory guidance for equipment and sludge trials

Application Process

1. Verify wetted materials, pump range, mixer design, and dilution-water supply on the dosing skid.
2. Commission the make-down system using the selected grade's instructions.
3. Check solution uniformity and feed calibration before the sludge trial.
4. Compare EWC 8040 and EWC 8060 on representative sludge at equal active mass.
5. Document the final recipe, start-up checks, and alarm response for operators.

Product Selection Guidance

EWC 8040 is the general starting grade. EWC 8060 should be included when the sludge has greater organic content or charge demand. Compare against an oil-based EC grade when the commercial decision requires evidence on performance and total handling cost.

Compare candidates on active polymer mass and total operating cost. Neat-emulsion price per kilogram can be misleading if products differ in activity, preparation efficiency, dose, equipment throughput, cake or underflow quality, and downstream disposal cost.

Operating Indicators to Record

• Solution consistency
• Sludge capture
• Water release
• Pump calibration
• Total chemical cost

Troubleshooting Note

If performance drifts between shifts, inspect the make-down sequence and water flow before changing grade. Entrained neat emulsion, poor mixing, or incorrect calibration can make a suitable product appear inconsistent.

Packaging, Storage, and Safe Handling

Standard supply options shown on the Blufloc PAM emulsion product pages are 25 kg containers, 200 kg plastic drums, and 1000 kg IBCs. Keep the package sealed in a cool, dry, ventilated area and protect it from direct sunlight, freezing, and excessive heat. Follow the grade-specific TDS and SDS for shelf life, handling limits, and transport classification. Polymer spills can make floors extremely slippery and should be contained and cleaned promptly.
