Product Introduction

Control Fast-Changing Site Water and Slurry

Construction wastewater can shift rapidly between rainwater dilution, cement-rich washout, bentonite slurry, TBM fines, and groundwater inflow. pH and suspended-solids loading may change by orders of magnitude as work fronts, geology, weather, and flow change.

Treatment must first address extreme pH or specific contaminants, then use coagulation and flocculation to separate suspended solids. Mobile dosing systems require robust calibration, containment, and protection from demanding site conditions.

Blufloc APAM Emulsion

Blufloc anionic PAM emulsion aggregates clay, cement fines, rock flour, bentonite, TBM fines, and other suspended mineral solids for settling, DAF, or mechanical separation.

Pumpable liquid grades support compact automated plants and variable project flow. Final selection depends on actual solids, pH, water chemistry, shear, equipment, and treatment target.

Application Challenges

Flow, Solids, pH, and Geology Can Change in the Same Shift

A practical polymer program must handle large TSS swings while fitting limited space, temporary pipework, variable treatment trains, and changing discharge or reuse targets.

Very High and Variable TSS

Excavation, washing, dewatering, rainfall, and groundwater inflow can change solids load and particle size rapidly.

Cement-Driven High pH

Cement washout can create extreme alkalinity that must be corrected before stable flocculation is expected.

Stable Bentonite and Clay

Fine bentonite, clay, and TBM slurry particles may remain colloidally stable without suitable pH and coagulation conditions.

Limited and Changing Footprint

Mobile and compact plants must remain controllable as project flow, treatment duty, weather exposure, and available space change.

Flocculation Mechanism

How the PAM Emulsion Works

After pH correction and particle destabilization as required, very-high-molecular-weight APAM adsorbs on fine mineral surfaces and bridges multiple particles into larger floc. Continuous emulsion preparation supports compact treatment units and changing project flow.

Stage 1

Correct Critical Chemistry

Address extreme cement pH and specific contaminants, then apply a coagulant when charge destabilization is required.

Stage 2

Distribute Activated APAM

Prepare and dilute the emulsion correctly so long polymer chains contact clay, bentonite, rock flour, and precipitated solids.

Stage 3

Separate and Verify

Protect formed floc through settling, DAF, or mechanical separation and verify discharge or reuse quality analytically.

Important: The suggested grades below are starting candidates, not a fixed prescription. Final selection and dosage require representative laboratory and plant trials.

Recommended Grades

Recommended Blufloc Screening Candidates

Test each major wastewater type separately and compare candidates at equal active polymer mass under representative pH, solids, water chemistry, temperature, mixing, shear, and residence time.

Grade	Base	Molecular Weight	Charge	Suggested Screening Role
EWA 7520	Water-based	Very High	Medium anionic	Practical starting candidate for compact mobile systems
EA 6520	Oil-based	Very High	High anionic	High-anionic candidate for difficult clay and rock fines

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.

Product Advantages

Flexible Liquid Treatment for Temporary and Compact Plants

Fast make-down for mobile and compact plants
Strong bridging of clay and rock flour
Potential for rapid settling and water reuse
Two carrier options for project requirements
Technical support as geology and slurry change

Application Process

Build Separate Control Bands for Each Site-Water Type

Segregate Major Wastewater Streams

Keep cement washout, bentonite slurry, tunneling slurry, and general site water separate where practical.

Characterize the Incoming Water

Measure pH, TSS, conductivity, dominant solids, flow, temperature, and any project-specific contaminants before treatment.

Correct pH and Destabilize Particles

Treat extreme pH and specific contaminants first, then add coagulant where required before APAM flocculation.

Calibrate Separate Dose Bands

Set preparation, dilution, pump output, and dose ranges for each major wastewater type and realistic flow or solids-load range.

Verify Compliance and Reuse Quality

Use analytical testing for discharge or reuse acceptance; visual clarity alone does not confirm treatment compliance.

Product Selection Guidance

Match the Grade to Solids, Chemistry, and Equipment

EWA 7520 is a convenient water-based candidate for compact mobile systems. EA 6520 should be screened for difficult clay, bentonite, rock flour, or high bridging demand. Extreme cement pH must be corrected before stable flocculation performance can be expected.

Re-screen when geology, excavation method, bentonite recipe, cement activity, groundwater inflow, rain dilution, treatment flow, reuse target, or separation equipment changes materially.

Compare Total Operating Cost

Neat-emulsion price per kilogram can be misleading. Compare active polymer mass with preparation efficiency, dose, equipment throughput, sludge or underflow quality, discharge compliance, reuse value, and disposal cost.

Troubleshooting

Correct Chemistry and Control Logic Before Raising the Dose

Bentonite Dispersion and Rainfall Swings

If bentonite remains dispersed, test coagulant choice, dose, pH, mixing, and addition sequence before increasing APAM. A higher polymer dose cannot reliably compensate for unsuitable particle-destabilization conditions.

If treatment varies with rain, adjust control logic for both water flow and solids load. Protect emulsion storage, preparation, pumps, and containment from construction dust, freezing, direct sunlight, excessive heat, and site impact.

Safe Handling

Storage and Handling

Keep the package sealed in a cool, dry, ventilated area. Protect it from direct sunlight, freezing, excessive heat, construction dust, water ingress, and physical damage.

Follow the grade-specific TDS and SDS for shelf life, handling limits, and transport classification. Polymer spills can make floors and site surfaces extremely slippery and should be contained and cleaned promptly.

Frequently Asked Questions

Construction and Tunneling Wastewater FAQ

Can APAM treat high-pH cement wash water directly?

pH correction and precipitation may be required first. APAM then helps aggregate and separate suspended or newly precipitated solids under the selected separation conditions.

Is APAM effective on bentonite?

It can be, but bentonite often requires careful optimization of coagulant, pH, polymer charge, dose, dilution, addition sequence, and mixing.

Can clarified water be reused for construction?

Only if analytical testing confirms that it meets the project's technical, equipment, environmental, and regulatory reuse requirements.

What is important for a mobile dosing skid?

Stable dilution water, correct emulsion inversion and activation, pump turndown, flow or solids pacing, containment, weather protection, and routine calibration are important.

Project-Specific Screening

Match APAM to Site Water, Geology, and Separation Equipment

Screen EWA 7520 and EA 6520 using representative cement washout, bentonite slurry, tunneling water, and general site-water samples. Select the grade, active dose, dilution, addition point, mixing, and control strategy using TSS removal, settling, sludge behavior, equipment throughput, discharge or reuse compliance, and total operating cost.
