China Anionic Polyacrylamide (APAM) Suppliers - High-Quality Flocculant for Water Treatment from Leading Factory

Anionic Polyacrylamide (APAM) is a highly effective water-soluble polymer featuring negatively charged molecular chains (-COOâ»). This versatile flocculant is designed to enhance water treatment processes by utilizing the electrical neutralization + adsorption bridging mechanism with positively charged suspended solids, such as sediments and colloids, as well as colloidal particles like iron hydroxide. As a leading solution for high-turbidity situations, including municipal sewage treatment, papermaking wastewater management, and mining wastewater processing, APAM is essential for achieving rapid coagulation and precipitation. Our factory in China supplies high-quality Anionic Polyacrylamide, ensuring optimal performance for various industrial applications. Choose us as your trusted suppliers to meet your water treatment needs efficiently

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), resistant to dilute acid/alkali, 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

QWhat is the molecular weight range of anionic PAM, and can it be customized?

The molecular weight of anionic PAM (APAM) ranges from 12 million to 20 million and is adjustable based on specific application requirements. Customized molecular weight configurations are available to match different wastewater treatment conditions and flocculation demands.

QHow long does it take for powder APAM to dissolve, and what is the recommended method?

Powder APAM dissolves within 60 minutes at room temperature. It is recommended to slowly add the powder to water while stirring continuously to avoid clumping. Using warm water (below 50°C) can slightly accelerate dissolution. Combining with PAC (polyaluminum chloride) further enhances flocculation performance.

QWhat pH range is anionic PAM suitable for?

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

QWhat industries and wastewater types is APAM most suitable for?

APAM is widely used in municipal sewage treatment, paper mill wastewater (black liquor and white water), mine and coal washing wastewater, and building materials production wastewater (cement and ceramic factories). It is particularly effective for high-turbidity wastewater with turbidity up to 5000 NTU, achieving a turbidity removal rate of ≥ 95%.

QWhat packaging options are available for anionic PAM?

Anionic PAM is available in 25 kg woven bags with an inner plastic liner, as well as 1-ton jumbo bags for bulk orders. Custom packaging with English labeling or customer-specific logos is also available upon request, making it suitable for international export requirements.

QWhat are the storage requirements and shelf life of anionic PAM?

Anionic PAM should be stored in a cool, dry environment with a temperature not exceeding 35°C, away from direct sunlight and moisture. When stored in unopened packaging under these conditions, the shelf life is 2 years. Exposure to humidity may cause clumping and reduce product effectiveness.
