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

Anionic Polyacrylamide (APAM) is a highly effective water-soluble polymer characterized by its negatively charged molecular chains (-COOâ»). It plays a crucial role in the treatment of high-turbidity water, making it an essential flocculant for various applications such as municipal sewage treatment, papermaking wastewater, and mining wastewater management. By utilizing the electrical neutralization + adsorption bridging mechanism, APAM efficiently binds with positively charged suspended solids and colloidal particles, facilitating rapid coagulation and precipitation. As a leading product provided by top China suppliers and manufacturers, our APAM is designed to meet the needs of industries requiring effective water treatment solutions. Trust our factory for high-quality Anionic Polyacrylamide that ensures optimal performance in challenging conditions

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

What is anionic polyacrylamide (APAM) and how does it work?

Anionic polyacrylamide (APAM) is a water-soluble polymer flocculant with a high molecular weight (12–20 million). It works by adsorbing suspended particles in water through charge neutralization and bridging effects, causing them to aggregate into larger flocs that settle rapidly, thereby clarifying wastewater efficiently.

What types of wastewater is APAM suitable for treating?

APAM is widely used in municipal sewage treatment, paper mill wastewater (black liquor delignification), mine and coal washing wastewater (coal slurry clarification), and building materials wastewater from cement and ceramic factories. It is effective for high-turbidity wastewater up to 5000 NTU.

What is the recommended pH range for using anionic PAM?

Anionic PAM performs stably across a pH range of 5–10. It is effective in both alkaline environments such as papermaking black liquor and acidic environments such as mine drainage, without corroding pipes or equipment.

How long does it take to dissolve anionic PAM powder?

Under normal room temperature conditions, anionic PAM powder dissolves within 60 minutes or less. Once dissolved, the resulting flocs are large and settle 25%–40% faster than conventional products. For best results, it is recommended to use APAM in combination with PAC (Polyaluminum Chloride).

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

Anionic PAM is available in 25 kg woven bags (with inner plastic liner) or 1-ton jumbo bags. Customized 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 sealed solid product is 2 years.

Is there a drinking water grade version of anionic PAM available?

Yes. A drinking water grade version is available with stricter heavy metal limits — for example, Fe ≤ 0.2%, As ≤ 0.0001%, Cr ≤ 0.0005%, and Hg ≤ 0.00001% — compared to the industrial grade. The drinking water grade also requires a higher Al₂O₃ content (≥ 29.0%) and lower insoluble matter (≤ 0.1%), ensuring safe use in potable water treatment applications.
