Product Introduction

Water-Based Emulsion for Controlled Continuous Preparation

EWA 7520 combines a water-based carrier with very-high-molecular-weight APAM. The format can simplify continuous liquid handling where the storage, preparation, and dosing skid is designed and commissioned for this grade.

Automatic dosing only delivers consistent treatment when dilution water, flow pacing, mixing, residence time, calibration, and line flushing are controlled. Product and equipment should be commissioned as one operating system.

Blufloc EWA 7520

Blufloc EWA 7520 is a water-based anionic PAM emulsion with very-high molecular weight and medium anionic degree.

It is designed for compatible automatic dosing systems serving wastewater clarification, mining, sand washing, paper, and selected sludge duties.

Application Challenges

Where Dosing-Skid Control Determines Treatment Consistency

Water-based formulation can support continuous handling, but it does not remove the need for correct make-down, activation, calibration, residence time, and low-dose distribution.

Changing Solution Strength

Unstable dilution-water flow changes prepared-solution concentration and the active polymer dose reaching the process.

Low-Rate Distribution

Small neat-emulsion flows require accurate metering and effective initial mixing to prevent localized overdosing.

Pump Turndown

Variable plant load can push a dosing pump outside its stable operating range and weaken flow-paced control.

Activation Assumptions

A water-based carrier does not mean neat dosing is automatically suitable or that polymer-chain preparation can be skipped.

Bridging Mechanism

How EWA 7520 Works

EWA 7520 provides medium anionic charge for adsorption and very-high molecular weight for bridging. Correct preparation exposes the polymer chains so they can aggregate fine mineral or coagulated solids without concentrated-product fish-eyes, uneven feed, or localized overdosing.

Step 1

Meter and Dilute

Control neat-emulsion and clean dilution-water flows according to the current grade-specific preparation instructions.

Step 2

Mix and Activate

Provide the specified mixing and residence time so polymer chains are distributed and available for adsorption.

Step 3

Bridge Under Control

Pace the dose to process load, distribute it rapidly, then protect growing floc from unnecessary shear.

Important: EWA 7520 is a starting candidate, not a fixed prescription. Final grade selection, preparation conditions, and dosage require representative laboratory and plant trials using the actual water chemistry, solids, hydraulic load, and dosing equipment.

Grade Profile

Recommended Blufloc Grade

Use this profile for initial screening and automatic-dosing system review. Confirm commercial specification limits and preparation instructions against the current EWA 7520 TDS and order specification.

Grade	Base	Molecular Weight	Charge	Suggested Screening Role
EWA 7520	Water-based	Very High	Medium anionic	Automatic dosing for clarification, mining, sand washing, paper, and selected sludge duties

Blufloc 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 active content, viscosity, specification limits, shelf life, and preparation instructions must be confirmed on the current grade-specific TDS and agreed order specification.

Product Advantages

Water-Based Handling with Very-Long Bridging Reach

Water-based emulsion format for compatible liquid-handling systems
Very-high molecular weight for long-chain solids bridging
Medium anionic degree for suitable mineral and coagulated solids
Suitable for compatible continuous preparation and dosing skids
Technical support for commissioning, calibration, and application trials

Application Process

Commission Product, Water, Pumps, and Controls as One System

Verify Equipment and Utilities

Check storage temperature, pump materials, pump turndown, mixer design, dilution-water capacity, containment, and line arrangement.

Commission the Make-Down Sequence

Use clean water and the current EWA 7520 instructions to confirm addition order, mixing, prepared concentration, and residence time.

Calibrate Across the Operating Range

Measure and document both neat-emulsion and dilution-water flows at low, normal, and high plant loads.

Pace Dose to Process Load

Link polymer feed to process flow or solids load and verify the control response with routine clarification or separation tests.

Document the Operating Procedure

Define start-up, steady operation, flushing, shutdown, spill response, alarms, and troubleshooting responsibilities.

Product Selection Guidance

Select EWA 7520 for a Compatible Water-Based Automatic System

EWA 7520 suits sites seeking a water-based, medium-anionic emulsion with very-high-molecular-weight bridging. Compare it with oil-based EA 6520 where higher anionic charge or a different carrier may provide better separation or whole-system economics.

Compare Total Operating Cost

Neat-emulsion price per kilogram can be misleading when products differ in activity, preparation efficiency, dose, and equipment throughput.

Active polymer mass and prepared-solution consistency
Clarifier, thickener, DAF, filter, or press throughput
Water clarity, cake quality, or underflow density
Equipment uptime, maintenance, storage, and disposal cost

Operating Control

Indicators to Record

Prepared-solution consistency
Pump calibration
Process-water clarity
Polymer active dose
System uptime

Troubleshooting

Audit the Dosing Skid When Treatment Drifts

If Raw Water Is Stable but the Result Changes

Check neat-product and dilution-water flowmeters, dilution-water pressure, pump stroke or speed, calibration records, and alarms. Confirm that actual flows match the control-system values.

Inspect the static mixer, preparation-tank turnover, residence time, injection quill, concentrated deposits, blocked lines, and flushing sequence before increasing the polymer dose.

Safe Handling

Storage and Handling

Keep packages sealed in a cool, dry, ventilated area. Protect the product from direct sunlight, freezing, process dust, contamination, and excessive heat.

Follow the current EWA 7520 TDS and SDS for shelf life, handling limits, and transport classification. Polymer spills make floors extremely slippery and should be contained and cleaned promptly.

Frequently Asked Questions

EWA 7520 Anionic PAM Emulsion FAQ

What are the main EWA 7520 specifications?

EWA 7520 is a water-based anionic PAM emulsion with very-high molecular weight and medium anionic degree. Confirm exact commercial limits on the current grade-specific TDS.

Is EWA 7520 ready to dose directly?

Follow the product-specific preparation instructions. A water-based formulation does not mean neat dosing is automatically appropriate or that make-down can be omitted.

Which industries can screen EWA 7520?

Industrial and municipal clarification, mining, sand washing, paper wastewater, selected sludge duties, and related solid-liquid separation applications can be evaluated.

What should an automatic dosing skid control?

Control neat-product flow, dilution-water flow, mixing, residence time, process pacing, alarms, flushing, and calibration across the normal operating range.

EWA 7520 System Commissioning

Commission Preparation, Control, and Separation Together
