Improve primary clarification, phosphorus-floc capture, and tertiary solids removal with oil-based EA 6520 and water-based EWA 7520 screening options.
Municipal plants may use polymer to improve primary clarification, wet-weather capture, chemically enhanced treatment, or tertiary solids removal. Each duty has a different particle load, hydraulic constraint, and downstream sensitivity.
Anionic PAM should be tested as part of the complete coagulation and mixing sequence, with attention to downstream biological treatment, filtration, sludge production, and chemical carryover.
Blufloc anionic PAM emulsion bridges destabilized fine solids to improve settling or filtration pretreatment in municipal wastewater TSS-removal duties.
EA 6520 and EWA 7520 can be evaluated after the plant's primary coagulant or phosphorus-removal chemistry.
Flow, particle load, upstream chemistry, mixer capacity, contact time, and clarifier or filter loading can all change between dry-weather and peak-flow operation.
Higher flow and TSS can shorten contact time, overload clarification, and reduce the opportunity for floc growth.
Metal-salt phosphorus removal can create fine precipitate that needs effective bridging before settling or filtration.
Floc may break through mixers, channels, launders, transfer points, or high-flow hydraulic transitions.
Residual polymer or coagulant can affect biological treatment or filters when dose, mixing, and separation are not balanced.
After the primary coagulant neutralizes colloids or forms precipitate, very-high-molecular-weight APAM bridges fine solids into settleable or filterable floc. Controlled mixing is essential: rapid dispersion at the injection point followed by gentle growth.
Use the actual municipal coagulant or phosphorus-removal chemistry to destabilize colloids or form precipitate.
Distribute the prepared APAM evenly at the injection point so the polymer contacts fine solids without local overdosing.
Reduce shear after initial dispersion so the bridged particles grow into floc suitable for settling or filtration pretreatment.
Use these grades as starting candidates and compare them at equal active polymer mass with the plant's actual coagulant under normal and wet-weather conditions.
| Grade | Base | Molecular Weight | Charge | Suggested Screening Role |
|---|---|---|---|---|
| EA 6520 | Oil-based | Very High | High anionic | Comparator for higher bridging or anionic charge demand |
| EWA 7520 | Water-based | Very High | Medium anionic | Water-based starting candidate for automated municipal dosing |
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.
Confirm whether the duty is primary capture, phosphorus-floc settling, or tertiary polishing before testing.
Run jar tests at representative dry-weather and wet-weather water quality with the plant's actual coagulant.
Verify that the selected dose does not create chemical carryover, biological inhibition, or filter problems.
Begin at stable flow, then confirm performance under peak hydraulic loading, realistic contact time, and plant shear.
Monitor sludge production and downstream dewatering, filtration, or biological response as part of the chemical balance.
EWA 7520 is a practical water-based first screen for municipal automatic systems. EA 6520 provides a higher-anionic oil-based comparator where fine coagulant precipitate or hydraulic stress requires stronger bridging. Confirm the preferred grade with representative laboratory and plant trials.
Neat-emulsion price per kilogram can be misleading. Compare on active polymer mass and include preparation efficiency, primary or tertiary performance, sludge production, downstream compatibility, and disposal cost.
If performance falls only during storms, the cause may be insufficient contact time, hydraulic short-circuiting, excessive clarifier loading, or mixer capacity rather than the APAM grade itself.
Review feed-forward dosing, flow and water-quality signals, injection distribution, mixer capacity, channel shear, and clarifier loading. Reconfirm coagulant dose and polymer carryover before simply increasing APAM.
Keep the package sealed in a cool, dry, ventilated area. 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.
For municipal primary and tertiary clarification, Bluwat can screen adjacent PAM emulsion grades, review preparation and dosing conditions, and help define a plant-trial plan using agreed TSS, settling, sludge-production, and downstream-response indicators.
Confirm the required grade specification and order documentation before production and shipment.
Shortlist products under realistic pH, temperature, solids, water chemistry, and shear.
Supply clear make-down, dilution, dosing, and scale-up recommendations for the selected grade.
Adjust charge level, dose, addition point, or mixing conditions using plant-trial data.
Yes, when fine solids are first destabilized and the downstream separation or filtration unit is compatible with the resulting floc.
APAM does not precipitate dissolved phosphorus by itself. It can help capture the precipitate formed by metal salts or another phosphorus-removal process.
Use flow and water-quality data with plant-specific dose bands, then verify chemical carryover, effluent quality, sludge production, and downstream impacts.
Any chemical program should be checked for downstream effects, especially when residual polymer or coagulant can reach the biological process.
Screen EWA 7520 and EA 6520 with representative normal- and wet-weather wastewater, the plant's actual coagulant or phosphorus-removal chemistry, controlled carrier-specific preparation, and realistic mixing. Confirm the preferred grade using effluent TSS, settling, dose, sludge production, peak-flow stability, downstream response, and total cost.
