Anionic Polyacrylamide APAM 20-100 Mesh 89% Minimum Solid Content for Oilfield Wastewater Flocculation

Product overview

Oilfield wastewater streams differ in oil content, fine solids, salinity and residual chemicals. A flocculant must be selected for the actual feed and treatment objective. Blufloc APAM can help evaluate polymer bridging after the particles or emulsion residues have been conditioned for separation.

Where oil emulsions are present, an emulsion-breaking treatment may be needed before flocculation. Coagulation and pH adjustment may also be required. Bluwat's selection approach compares the complete treatment sequence, rather than expecting APAM alone to remove every oilfield contaminant.

Technical specifications

Grade selection for this application

Provide the wastewater source, pH, salinity, suspended solids, oil characteristics, existing chemicals and treatment equipment. State whether the main target is clarified water, flotation performance, sludge thickening or another measurable endpoint.

A useful screening sequence for suitable oily waters is emulsion breaker, optional polyaluminium chloride coagulant, pH adjuster and then APAM. A pH of 7–8 may be tested as a starting condition where appropriate, but the optimum must be confirmed for the actual water and chemical package. Adjust pH before adding PAM.

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 25 kg kraft paper bag with an inner plastic liner. 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.
