Wholesale Anionic Polyacrylamide (APAM) Flocculant for Water Treatment - Leading China Suppliers & Factory Supplier, Suppliers

Anionic Polyacrylamide (APAM) is a highly effective water-soluble polymer featuring negatively charged molecular chains (-COOâ»). As a core flocculant, it utilizes the electrical neutralization + adsorption bridging mechanism to effectively address high-turbidity scenarios. This product works by rapidly coagulating and precipitating positively charged suspended solids, including sediments, colloidal particles, and iron hydroxide found in various water sources. APAM is widely utilized in municipal sewage treatment, paper wastewater management, and mining wastewater processing. As a leading manufacturer and supplier of Anionic Polyacrylamide in China, we ensure high-quality products from our factory to meet the rising demand in industrial applications

Product Description

Core Features

Precise Molecular Weight Control: The molecular weight of anionic PAM ranges from 12 million to 20 million (adjustable), with long and uniform molecular chains, showing significant flocculation effects on high-turbidity wastewater (turbidity ≤ 5000 NTU), and the turbidity removal rate is ≥ 95%.

Fast Dissolution, Low Residue: The dissolution time of powder PAM ≤ 60 minutes (at room temperature), after dissolution, the flocs are large and settle quickly (settling speed is 25%–40% faster than conventional products), and it works better when used in combination with PAC. Water insoluble matter ≤ 0.5%.

Strong Tolerance: Resistant to acid and alkali (pH 5–10), has a stable effect on papermaking black liquor (high alkalinity) and mine acidic wastewater (low pH), and does not corrode pipes or equipment.

Application Area

Municipal Sewage: Flocculation in the primary sedimentation tank and secondary sedimentation tank of urban domestic sewage treatment plants to reduce SS (suspended solids) to below 10 mg/L.

Paper Mill Wastewater: Delignification of pulping black liquor, white water recovery (fiber collection rate increased by 15%–20%).

Mine / Coal Washing Wastewater: Clarification of coal slurry water (collection rate of flotation clean coal increased by 8%–12%), flocculation and sedimentation in tailings pond.

Building Materials Wastewater: Production wastewater from cement plants and ceramic factories removes suspended solids (turbidity reduced from 2000 NTU to 50 NTU).

Packaging and Storage

Solid Powder: 25 kg woven bag lined with plastic bag / 1 ton jumbo bag (customizable English / customer logo packaging available).

Storage Conditions: Store in a cool, dry place (temperature ≤ 35°C), avoid direct sunlight; the shelf life of the solid is 2 years (unopened).

Frequently Asked Questions

Q What is the molecular weight range of anionic PAM (APAM)?

The molecular weight of anionic polyacrylamide (APAM) ranges from 12 million to 20 million and is adjustable based on application requirements. The long and uniform molecular chains provide strong flocculation performance, especially for high-turbidity wastewater with turbidity up to 5000 NTU.

Q How long does anionic PAM powder take to dissolve?

Anionic PAM powder dissolves within 60 minutes at room temperature. After dissolution, the resulting flocs are large and settle quickly — 25%–40% faster than conventional products. The water insoluble matter content is ≤ 0.5%, ensuring minimal residue.

Q What pH range is anionic PAM suitable for?

Anionic PAM is resistant to both acid and alkali environments, performing stably across a pH range of 5 to 10. This makes it effective for treating papermaking black liquor (high alkalinity) as well as mine acidic wastewater (low pH), without corroding pipes or equipment.

Q What industries and wastewater types is anionic PAM used for?

Anionic PAM is widely used in municipal sewage treatment, paper mill wastewater (pulping black liquor and white water recovery), mine and coal washing wastewater (coal slurry clarification and tailings pond sedimentation), and building materials wastewater from cement and ceramic plants.

Q What are the packaging options and shelf life for anionic PAM?

Anionic PAM is available in 25 kg woven bags (lined with plastic bags) or 1-ton jumbo bags. Custom English labeling and customer logo packaging are available. When stored in a cool, dry place at temperatures ≤ 35°C and away from direct sunlight, the shelf life of the unopened solid product is 2 years.

Q What is the difference between Industrial Grade and Drinking Water Grade anionic PAM?

Drinking Water Grade anionic PAM has stricter specifications than Industrial Grade, including higher Al₂O₃ content (≥ 29.0% vs ≥ 28.0%), lower insoluble matter (≤ 0.1% vs ≤ 0.4%), and significantly lower heavy metal limits (Fe, As, Cr, Hg, Pb, Cd), making it safe for use in potable water treatment applications.
