Ultra-high molecular weight for tailings and water recovery
Blufloc AA8520 is an anionic polyacrylamide powder with an ultra-high molecular-weight range of 20-25 million and an anionic degree of 30-45%. It is listed for raw-water and industrial treatment, sludge thickening and dewatering, and process-water recovery.
The product is a water-soluble copolymer of acrylamide and acrylic acid, supplied as a free-flowing, off-white granular powder. AA8520 is a candidate for screening programs that require this molecular-weight and anionic-degree combination, with final selection based on the actual feed and separation duty.

Values above follow the supplied grade-specific TDS. The bulk-density unit is not given in that sheet. The specific-gravity entry gives 25°C but does not state the sample concentration. The pH test concentration is not stated; confirm the test basis for purchasing comparisons.
The supplied TDS lists tailings thickening and water recovery in mining, metallurgy and coal processing. Test AA8520 on representative slurry and compare the condition of the separated liquid and solids. The stated molecular-weight and charge ranges identify the grade but do not predict a numerical settling rate.
Raw-water flocculation and clarification, lime-alum sludge dewatering and water recovery, primary industrial clarification, secondary or tertiary treatment, color removal, primary sewage treatment and sludge thickening or dewatering are listed. Define the treatment objective before setting up the laboratory comparison.
Other listed applications include paper-making water recovery, chlor-alkali brine clarification and thermal-power scrubber-water clarification. Drilling fluids, EOR, fluid-loss control, lubrication and shale stabilization are also included. A grade selection for these uses requires a stream-specific or formulation-specific evaluation.
AA8520 and AA6520 have overlapping ultra-high molecular-weight ranges but different anionic degrees. AA8520 lists 20-25 million and 30-45%, while AA6520 lists 20-24 million and 20-30%. AA8519 offers a further comparison at 18-20 million and 30-40%. Choose the screening set around the process question rather than assuming direct interchangeability.
| Grade | Molecular weight and charge-related specification |
|---|---|
| AA8520 | 20-25 million; anionic degree 30-45% |
| AA6520 | 20-24 million; anionic degree 20-30% |
| AA8519 | 18-20 million; anionic degree 30-40% |
The comparison identifies specification differences. It is not a performance ranking or an interchangeability statement.
The TDS recommends preparation as a 0.1-0.5% solution before use. This is the polymer solution concentration, not a fixed dose in the treated water or slurry.
The supplied instructions specify plastic, enamel or fiberglass containers for solution storage and advise against metal containers. Allow the polymer solution to dissolve before the application trial. Ask for grade-specific make-down guidance for the actual water, temperature and mixing equipment; the TDS does not provide a mixing speed.
Run a laboratory comparison using the actual water, wastewater, slurry or sludge. Record the feed condition, polymer concentration, dose basis, mixing and separation result. The TDS gives no universal treatment dose.
Use the selected conditions in an equipment trial before routine production dosing. Where another coagulant or process aid is used, include that chemical program in the evaluation; the TDS does not specify a universal chemical-addition sequence.
Blufloc AA8520 is listed in 25 kg Kraft paper bags with inner plastic liners. Confirm the packaging configuration and quantity in the quotation.
Store the product in its original packaging in a cool, dry place, away from heat, flame and direct sunlight. The listed storage temperature is 0-35°C. The TDS states a shelf life of 2 years. Refer to the current product label and SDS for handling instructions.
No. The range identifies AA8520, while the process result must be established on the actual water or slurry. Compare suitable grades and doses under representative conditions.
The TDS lists a two-year shelf life and storage at 0-35°C. Keep the product in its original packaging in a cool, dry place away from heat, flame and direct sunlight.
AA8520 is an anionic polyacrylamide powder. Its molecular-weight range is 20-25 million and its anionic degree is 30-45%. The supplied TDS identifies it as an off-white granular product with a particle size of 20-100 mesh.
Determine the dose by laboratory and equipment trials on the actual feed. A 0.1-0.5% working concentration describes the prepared solution in the TDS; it is not a treatment dose in mg/L. No universal treatment dose is provided.
Assess replacement through a side-by-side trial with the existing treatment program. The supplied data do not establish automatic replacement of alum, ferric salts, another PAM grade or a complete treatment process.
Contact Bluwat with the grade code, intended application, feed information, required quantity and packaging. Ask for the current grade-specific TDS, SDS and order specification, and discuss sample testing for the proposed duty.
