Product Introduction

Stabilize Settling Across Variable Sand-Washing Loads

Sand and aggregate plants generate large water flows containing abrasive mineral solids and variable clay. Storms and feed changes can rapidly raise turbidity and overload settling ponds or compact clarifiers.

Emulsion polymer supports fast make-down and automated dosing, but the system must be protected from grit and calibrated for both diluted flow and high-solids peaks.

Blufloc APAM Emulsion

Blufloc anionic PAM emulsion aggregates clay, silt, and ultrafine mineral particles for faster settling and clearer recycled wash water.

Oil-based and water-based grades support fixed clarification equipment, compact automatic dosing systems, and mobile sand-washing plants.

Application Challenges

Why Sand-Washing Clarification Can Change Within Hours

Clay content, feed grading, rainfall dilution, hydraulic retention time, and equipment condition can shift polymer demand and recycled-water quality quickly.

High Clay and Silt Load

Stable ultrafine suspensions can remain cloudy after coarse sand and aggregate particles settle.

Short Settling Time

Compact clarifiers and mobile systems provide limited time for polymer distribution, floc growth, and separation.

Feed and Rainfall Swings

Raw-material changes and storms can alter water flow, TSS, clay fraction, and the required pump output.

Abrasion and Plugging

Grit, dust, weather, poor containment, and concentrated polymer can damage or obstruct dosing equipment.

Treatment Mechanism

How the PAM Emulsion Works

Very-high-molecular-weight APAM adsorbs onto mineral surfaces and bridges fine clay, silt, and ultrafine particles into rapidly settling floc. Anionic charge supports chain extension in many mineral-water systems, while correct pre-dilution improves distribution across high flow.

Step 1

Activate and Pre-Dilute

Prepare the emulsion according to the grade-specific TDS and avoid feeding concentrated polymer directly into poorly mixed water.

Step 2

Bridge the Mineral Fines

Long APAM chains connect dispersed clay, silt, and ultrafine aggregate particles into settleable floc.

Step 3

Settle and Recycle

Preserve floc through the clarifier to improve settling, sludge concentration, and recycled wash-water clarity.

Important: The grades below are starting candidates, not a fixed prescription. Final selection and dosage require representative laboratory and plant trials covering normal feed, high-clay conditions, rainfall dilution, actual settling time, and full-scale mixing.

Recommended Grades

Recommended Blufloc Grades

Compare candidates at equal active polymer mass using representative wash water and the actual TSS, clay fraction, pH, recycle ratio, temperature, and hydraulic conditions.

Grade	Base	Molecular Weight	Charge	Suggested Screening Role
EWA 7520	Water-based	Very High	Medium anionic	Convenient candidate for compact automatic dosing
EA 6520	Oil-based	Very High	High anionic	Strong candidate for clay-rich or demanding settling

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. Confirm exact commercial specification limits, active content, viscosity, shelf life, and preparation instructions on the current grade-specific TDS and order specification.

Application Process

Match the Test to Real Flow, Solids, and Settling Time

Collect Representative Samples

Sample both normal production and high-clay conditions without allowing selective settling before testing.

Characterize the Duty

Record water flow, TSS, clay content, particle size, pH, temperature, and the recycled-water ratio.

Screen Dose and Mixing

Compare grade, active dose, dilution, rapid mix, floc growth, and settling under the plant's actual time limits.

Calibrate Automatic Dosing

Link polymer flow to wash-water flow, solids load, or both, then verify pump output across the operating range.

Protect the Dosing System

Shield storage, make-down, pumps, and lines from grit, plugging, abrasion, weather, freezing, and direct sunlight.

Product Selection Guidance

Compare Carrier, Charge, and Plant Compatibility

EWA 7520 is a practical water-based option for compact systems and automatic dosing. EA 6520 should be included when clay-rich feed or demanding settling benefits from stronger high-anionic bridging.

Confirm the preferred grade separately for normal production, high-clay feed, rainfall dilution, mobile operation, and other major flow or feed regimes.

Compare Total Operating Cost

Neat-emulsion price per kilogram can be misleading. Compare active polymer mass and include preparation efficiency, dose, equipment throughput, sludge or underflow quality, recycled-water value, maintenance, and disposal cost.

Active polymer dose per ton of feed or volume of wash water
Settling time, recycled-water turbidity, and clarifier throughput
Sludge density, handling, and downstream disposal requirements

Troubleshooting

Separate Storm Dilution From Peak Solids Loading

A Fixed Pump Setting May Fail in Both Directions

If treatment deteriorates during storms, determine whether the dosing signal follows water flow, solids load, or both. A fixed output may underdose peak TSS while overdosing heavily diluted wash water.

Also verify polymer activation, dilution, pump calibration, injection-point mixing, blocked lines, grit wear, and actual clarifier retention time before increasing dose.

Safe Handling

Storage and Handling

Keep the package sealed in a cool, dry, ventilated area. Protect it from direct sunlight, freezing, excessive heat, dust, and grit contamination.

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.

Frequently Asked Questions

Sand-Washing Water Flocculation FAQ

Can APAM help recycle sand-washing water?

Yes. Improved clay, silt, and ultrafine-particle settling can clarify water for reuse, subject to the plant's process-water quality requirements.

Is water-based EWA suitable for mobile plants?

It can be. The compact dosing system must provide correct activation, dilution, containment, pump control, grit protection, and protection from weather extremes.

How should dose follow variable TSS?

Use site-specific flow-based, solids-based, or combined control supported by routine jar tests, TSS checks, recycled-water monitoring, and pump calibration.

Will polymer remove dissolved salts?

No. APAM mainly separates suspended mineral solids. Dissolved salts require another treatment process if they affect water reuse, discharge, or downstream equipment.

EA and EWA Screening

Match the APAM Grade to Clay Load, Flow Variation, and Clarifier Duty

Screen EWA 7520 and EA 6520 with representative normal and high-clay wash water, controlled carrier-specific preparation, actual settling time, and plant-like mixing. Confirm the preferred grade using settling time, recycled-water turbidity, sludge density, polymer consumption, clarifier throughput, dosing-system reliability, and total operating cost.
