Anionic Polyacrylamide APAM 20-100 Mesh 89% Min Solid for Oil Sands Tailings Thickening CAS 9003-05-8 ISO 9001 Manufacturer 750kg Net Big Bag

Product overview

Oil-sands tailings can combine fine mineral particles, clay, process-water salts and residual hydrocarbons. Thickener performance depends on both floc formation and the ability of the concentrated solids to settle, compact and move through the underflow system. APAM screening must assess these outcomes together.

Bluwat evaluates candidate flocculants using representative tailings and the proposed process conditions. A fast initial settling rate is useful only when the overflow and underflow also meet requirements. Performance in one tailings sample should not be generalized to every oil-sands feed or process-water composition.

Product benefits

Technical specifications

Grade selection for this application

Provide feed solids, fine-particle and clay information, process-water chemistry, residual oil and the thickener operating targets. Include feedwell conditions, underflow pumping limits and the required water-recovery quality.

Evaluate dosage in a stated dry-solids basis where appropriate and test more than the early settling interface. Compare supernatant turbidity, final solids concentration, compaction behavior and underflow handling. Excessive polymer can increase cost or alter the underflow response, so optimize against the entire process.

Application evaluation and use

Solution preparation and dosing

Use clean, compatible make-up water and add the powder gradually into an established mixing flow. Avoid dumping powder in one location, which can create lumps with dry cores. The TDS gives 0.1–0.5% as general solution-preparation guidance. If specified on an as-supplied powder mass basis, this corresponds to 1–5 kg of powder per 1,000 kg of final solution; agree the concentration basis for the project.

Allow approximately one hour of agitation as a starting reference, then confirm complete hydration. Water quality, temperature, grade and equipment affect the required time. The TDS’s 200–400 rpm reference is equipment dependent and should not be scaled to a different tank solely by rpm. Avoid severe shear after hydration. Determine the final treatment dosage through the application tests described above.

Packaging storage and handling

The featured packaging is a 750 kg net big bag. Confirm unloading, metering and moisture-protection requirements for the receiving site. The TDS also lists 25 kg kraft paper or PE bags and 750 kg net big bags. Store powder dry, protected from direct sunlight and at 0–35°C. Keep opened packaging tightly closed. Consult the current SDS for handling, spill control and personal protection.
