Anionic Polyacrylamide (APAM) is a highly effective water-soluble polymer widely used as a flocculant for wastewater treatment, industrial applications, and sludge dewatering. It has a negative charge that enhances its ability to bind with suspended particles, helping to separate solids from liquids efficiently. APAM is commonly used in municipal sewage treatment, industrial effluent clarification, paper production, and more.

Note: Exact specs available on request. We offer tailored grades for sludge dewatering, paper retention, and mining flocculation.
Clarification, tertiary treatment, and enhanced sludge dewatering in WWTPs and industrial effluent lines.
Tailings thickening, fine-particle recovery, and flotation feed conditioning—improves recovery and water reuse.
Retention aid and drainage improver—better sheet strength and less fiber loss in the wet end.
These are starting guidelines. Always perform jar tests and pilot trials to determine the optimal grade and dose for your water matrix.
Stock solution: Prepare 0.1–0.5% solution (w/v) using clean water; use low-shear mixing to avoid chain breakage.
Typical screening dose: 1–10 mg/L for clarification; dosing can be higher for heavy sludge conditioning.
Dosing point: Add APAM after primary coagulant (e.g., PAC) as a flocculant aid to improve floc strength and dewatering.
Jar test procedure: Rapid mix → slow flocculation → settle; measure turbidity, floc strength, and sludge volume.
Tip: Combining APAM with coagulants such as polyaluminium chloride (PAC) often yields the best results for turbidity & color removal.
| Parameter | APAM | Alum / Ferric |
|---|---|---|
| Dosage | Low (1–10 mg/L) | Higher (10–100 mg/L) |
| Sludge volume | Lower, denser | Higher, wetter |
| pH sensitivity | Low (broad window) | High (narrow window) |
| Dewatering | Good | Relatively poor |

Bulk packaging: 25 kg bag / 900 kg pallet / ISO tank options available.
A1: High-purity APAM grades with controlled residual monomer can be used as a flocculant aid in potable water systems when dosed and monitored according to local regulations. Always follow jar-test results and regulatory limits for residuals.
A2: Store in a dry, cool place; keep bags sealed. Avoid moisture and direct sunlight. Typical shelf life is 12 months under proper storage.
A3: Higher molecular weight improves bridging and dewatering but may reduce shear-stability. Select MW based on process (belt press vs centrifuge) and run jar tests to finalize choice.
