Product Introduction

Flocculate After the Emulsion Has Been Broken

Oil droplets stabilized by surfactants or fine solids do not behave like normal suspended mineral particles. A flocculant cannot reliably replace the demulsification step that destabilizes the oil-water interface and releases the dispersed phase.

Once destabilized, oil-bearing solids and coagulant floc can be aggregated by APAM for DAF, settling, or filtration. Excessive shear after polymer addition can break floc and re-disperse the separated phase.

Blufloc APAM Emulsion

Blufloc anionic PAM emulsion is applied after demulsification or coagulation to bridge separated oil-bearing solids, precipitate, and coagulant floc into larger aggregates.

Liquid grades support continuous preparation and dosing for flotation or settling. Final selection depends on the destabilized solids, oil type, pH, temperature, shear, separation equipment, and required treated-water quality.

Application Challenges

Oil Chemistry and Separation Conditions Change the Result

Successful treatment requires the correct chemical sequence, representative testing, and enough floc strength for the selected DAF, clarifier, or filtration process.

Stable Emulsions and Surfactants

Surfactants and interfacial films can keep oil droplets dispersed until a suitable demulsifier or coagulant destabilizes them.

Fine Oil-Bearing Solids

After coagulation, very small oil-coated particles and precipitate may still require long-chain bridging for efficient separation.

Changing Oil, Temperature, and pH

Feedstock, cleaning chemicals, temperature, salts, pH, and suspended solids can change demulsification and polymer demand.

Carryover and Floc Breakage

Poor chemical order, insufficient bubble contact, low settling density, or excessive shear can carry oil into treated water.

Flocculation Mechanism

How the PAM Emulsion Works

After the emulsion is destabilized and droplets or solids have suitable adsorption sites, very-high-molecular-weight APAM bridges them into separable floc. DAF floc must attach effectively to bubbles, while settling floc must develop enough density to sink.

Stage 1

Break and Destabilize the Emulsion

Optimize demulsifier, coagulant, pH, temperature, and mixing until the dispersed phase becomes available for separation.

Stage 2

Add Activated APAM Last

Distribute the prepared polymer rapidly, then reduce shear so the long chains can bridge oil-bearing solids and precipitate.

Stage 3

Float, Settle, or Filter

Match floc size, strength, bubble attachment, and density to the actual separation device and verify residual oil 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

Stabilize the upstream demulsification or coagulation program before comparing APAM candidates at equal active polymer mass under representative oil, solids, pH, temperature, shear, and separation conditions.

Grade	Base	Molecular Weight	Charge	Suggested Screening Role
EWA 7520	Water-based	Very High	Medium anionic	Water-based candidate for post-coagulation separation
EA 6520	Oil-based	Very High	High anionic	High-anionic comparator for difficult fine solids

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

Optimize the Separation Sequence Before Scaling Up

Characterize the Oil and Solids

Measure free, dispersed, and emulsified oil together with TSS, pH, temperature, salts, surfactants, and flow variation.

Optimize Upstream Destabilization

Establish the demulsifier, coagulant, pH, dose, addition point, and mixing conditions before APAM screening.

Add APAM Last

Use rapid initial distribution followed by gentle floc growth to avoid breaking the separated phase or formed aggregates.

Measure the Complete Result

Evaluate oil in water, TSS, DAF or settling behavior, sludge volume, sludge quality, dewatering, and treated-water compliance.

Maintain Chemical Order at Plant Scale

Preserve the successful order, dilution, addition points, contact time, and shear conditions when transferring the trial to the plant.

Product Selection Guidance

Match APAM to the Destabilized Solids and Separation Device

EWA 7520 is a practical water-based candidate for post-coagulation screening. EA 6520 provides higher anionic charge and strong bridging for comparison when difficult fine solids remain after destabilization.

Select the grade using the actual oil type, destabilized particle surface, residual coagulant, salts, pH, temperature, DAF bubble conditions, settling density, filtration duty, shear history, and treated-water target.

Compare Total Operating Cost

Neat-emulsion price per kilogram can be misleading. Compare active polymer mass with preparation efficiency, dose, equipment throughput, treated-water quality, sludge or underflow properties, dewatering, and downstream disposal cost.

Oil and TSS removal at the required throughput

Troubleshooting

Check Demulsification and Separation Before Raising APAM Dose

No Separate Phase or Persistent Oil Carryover

If no separate phase forms before APAM addition, revisit the demulsifier, coagulant, pH, temperature, dose, addition sequence, and mixing. APAM cannot reliably replace the step that breaks a stable oil-water emulsion.

If floc forms but oil carryover remains high, examine DAF recycle, bubble size and attachment, hydraulic loading, settling density, short-circuiting, and downstream shear before increasing polymer dose.

Safe Handling

Storage and Handling

Keep the package sealed in a cool, dry, ventilated area. Protect it from direct sunlight, freezing, excessive heat, 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 extremely slippery and should be contained and cleaned promptly.

Frequently Asked Questions

Oily Wastewater Flocculation FAQ

Can APAM break an oil-water emulsion?

Its main role is flocculation after destabilization. Stable emulsions generally require a dedicated demulsifier or coagulant step before APAM is used for bridging.

Is APAM suitable for DAF?

Yes, when the upstream emulsion has been destabilized and the floc is formed and mixed to support bubble attachment without excessive shear.

Why might floc float in one plant and settle in another?

Oil content, solids density, air-to-solids ratio, bubble contact, hydraulic conditions, and separation design determine whether the aggregate floats or sinks.

Should oil and grease be measured after treatment?

Yes. Visual clarity and TSS do not fully describe residual oil. Use the required analytical method and confirm treated-water quality against the applicable discharge or reuse target.

Process-Specific Screening

Match APAM to the Demulsified Solids and Separation Equipment

Screen EWA 7520 and EA 6520 only after the demulsifier, coagulant, pH, and mixing program has been stabilized. Select the grade, active dose, dilution, addition point, shear, and separation settings using oil and grease, TSS, DAF or settling performance, sludge properties, throughput, and total chemical cost.
