Blufloc EC 8040 to EC 8080 Oil-Based Cationic PAM Emulsion Series

Product Introduction

Purchasers sometimes compare cationic PAM emulsions only by price or a single charge number. In practice, the optimum is the interaction of charge, molecular weight, carrier system, activation, sludge chemistry, and equipment shear.

The EC series provides a structured screening ladder. This makes it possible to compare adjacent charge levels while keeping the product family and handling format consistent.

The Blufloc EC 8040 to EC 8080 series provides oil-based cationic PAM emulsions with high molecular weight and medium, high, very-high, or ultra cationic charge. The range supports sludge-specific screening across municipal and industrial dewatering.

Application Challenges

• Selecting a grade without representative sludge testing
• Assuming the highest charge is automatically the strongest product
• Comparing neat volume rather than active polymer mass
• Ignoring make-down quality and carrier compatibility

How the PAM Emulsion Works

All EC grades use cationic functionality to neutralize anionic particles and high-molecular-weight chains to bridge them. Increasing charge can accelerate adsorption on organic sludge, but it can also change floc size, drainage, and sensitivity to overdosing.

Recommended Blufloc Grades

The product pages classify the cationic EC and EWC series as high molecular weight and the anionic EA and EWA grades as very high molecular weight. Exact commercial specification limits, active content, viscosity, shelf life, and preparation instructions should be confirmed on the current grade-specific TDS and order specification.

Product Advantages

• Four charge levels within one oil-based product family
• High molecular weight for particle bridging
• Fast liquid make-down for automated systems
• Application coverage from thickening to mechanical dewatering
• Factory support for grade ladder screening

Application Process

1. Select two or three adjacent EC grades based on sludge origin and upstream chemistry.
2. Prepare every candidate with the same water quality, active concentration, and activation procedure.
3. Apply the same shear and observation time during bench testing.
4. Advance the best two candidates to a machine trial at equal active-mass comparison points.
5. Choose on total treatment cost and operational stability, then retain the runner-up as a contingency grade.

Product Selection Guidance

EC 8050 is a sensible center point for a first screen. Move toward EC 8040 when residual coagulant or lower organic content reduces charge demand; move toward EC 8060 or EC 8080 when strongly negative organic sludge requires more charge.

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

• Active polymer dose
• Floc strength
• Water release
• Machine capture
• Total operating cost

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.

Why Choose Bluwat Chemicals
