89% Minimum Solid Content 2-Year Shelf Life Anionic Polyacrylamide APAM Powder in 750kg Net Big Bag

Product overview

Produced water can contain suspended mineral particles, corrosion products, dispersed oil, salts and residual treatment chemicals. Clarification requires a process matched to those contaminants. APAM is evaluated here as a flocculant for suitable particles or previously destabilized aggregates, rather than as a universal treatment for all dissolved and emulsified material.

Bluwat can consider the flocculant alongside the required pretreatment and separation method. Depending on the water, free-oil removal, emulsion breaking or coagulation may be needed before polymer addition. The final grade and sequence should be selected by jar testing and equipment trials.

Product benefits

Technical specifications

Grade selection for this application

Provide salinity, pH, temperature, suspended solids, oil content, residual production chemicals and the required outlet quality. Identify whether separation uses settling, flotation or another process because the preferred floc structure and operating conditions may differ.

Test the actual water and its expected variability. Salinity affects polymer response, while anionic APAM may require suitable coagulation before it can bridge particles effectively. Evaluate clarified-water quality and sludge or float handling together; rapid settling alone is not sufficient if the overflow remains turbid.

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.
